Transcoding

The Transcoding page is where all of the magic happens.  Users can drag and drop files, while power users can link up cloud data storage from (aws, google and oracle clouds), use templates, curl and or API calls to batch their high volume jobs.

Please Note: This page is a dynamic page which changes based on what has been selected, your page may look different.  Choosing cloud resources, separating audio from video, adding multiple audio tracks and using video ladders adds more complexity to this page.  Drag and drop, using temporary storage and video files with embedded audio reduces complexity.

Transcoding Page Overview

1.) Access other Pages, Home page and Log out

Access any page by clicking on it in the left menu.

2.) Blue Triangle

This page can be very advanced, generally start with the blue triangle pointed down and only expose the options you want to turn on.  Once you get comfortable with this you can use more options by clicking the triangle to the up position.

3.) INPUT LOCATION

Where is the input video file located?  file-upload (default), aws, gcloud, oracle cloud, or any http or https URL.  With file-upload you can drag and drop a video file from your web browser.  As the file is uploading do not close the web browser that you are on.  Open a second browser window if you want to do additional work while you wait for the file to upload. 

To use AWS, google cloud or Oracle cloud see detailed settings in documentation below.

4.) OUTPUT FORMAT

Select output format MP4, TS, DASH, HLS or DASH+HLS.  Separate Audio

5.) COMMON OUTPUT SETTINGS

Cloud providers for video input 

If you are using any cloud providers please make sure you save your templates, when you are done configuring them.  All of the fields under the cloud provider are required and will need to be filled in to run properly. Wild cards are not supported at this time, if you want to batch process videos you will need to use scripts either with curl or api.

Please Note: Fields that are required will have a red box around them.  Depending on settings and options you choose different fields may be required.

1.) AWS

AWS - Amazon Web Services one of the oldest and largest cloud providers. AWS offers a free tier and paid tier if you need more resources.  It will require a credit card to signup.  To use with StreamEngine we recommend S3 buckets* (their file system) make sure you have some sort of permissions on your files so that you stay within your budget.   *AWS has many options for file storage that you can use as well.

transcoding input aws with numbers.png

  1. If using Amazon Web Services select AWS in the pull down.  
  2. Use your input file location on AWS starting with S3://   be sure to put the full name of the file with extension. 
  3. Paste your Access Key into the Access Key field.
  4. Paste your Secret Key into the Secret Key field.
  5. Select the Region in the drop down list.

Please Note: Fields that are required will have a red box around them.  Depending on settings and options you choose different fields may be required.  For AWS

2.) Oracle Cloud

Oracle Cloud Infrastructure is provided by Oracle corporation, the makers of the leading database used by corporate America as well as other products.  Oracle cloud is used by StreamEngine for temporary storage.  Oracle cloud has a free tier and limited trial as well.  For use with StreamEngine you will need Oracle File Storage and security to restrict access.

6.) Paste your client id into the Client ID field.
7.) Select the private key id in the Private Key ID field.
Optional - Save this as a template so it remembers your settings.

4.) HTTP(S)

If you want to convert a file on the web that you have permissions to use or if it is a public domain video.  You can use the web video url with StreamEngine to convert the video.   This does not work for YouTube and other videos without file extensions.

transcoding input http with numbers.png
1.) Select http from the drop down list.
2.) Enter the http or https url with the full name of the file including the extension.

5.) File-Upload

The most common is file-upload.  When you click on File-Upload, you'll see a form similar to the one below.  The first time you will see a blank drop down list, after a few conversion you can select files that have been recently uploaded by selecting the drop down menu.  If you want to convert a new file drag and drop it over the green down arrow.  If you click on the green arrow you can browse for the file you want.  If you are on a mobile device or tablet the green arrow is a great option and will even allow you to take a new video from your camera.

input file-upload-newuser-w-5numbers.png

For new users, this is the default for input location and will look like the image above.  Options 2 & 3 do not have any files that were loaded so they can't be picked from the drop down or sorted.

input file-upload-olduser-w-numbers.png

If you have been using the system for a little while it may have a history of files that are in your temporary storage location. In the example above the last file used was a GoPro file and that is the most current file.  If you want to use the file in the drop down list you do not have to do any more.  Or you can select an existing file or upload a new file.  If you have more than one file they can be sorted A-Z or reverse sorted Z-A.  These sorts are based on the first character of the file name only. Files in temporary storage are only available for a limited time.

1.) To upload a file select file-upload from the drop down list.
2.) Existing file list, these files are in your private igolgi temporary storage.  If you want a file already used, you can select it. If you know the file name you can type the first letter to find it faster.
3.) Sort the files in the list.  Sorting is a toggle if its clicked on it will be sorted in that order until reverse search is clicked on.

Sorted A-Z

transcoding-input-location-dropdown-sorted-AZ.png

Sorted Z-A

4.) Click the green arrow to browse for a video file on your local disk or mobile device.

5.) Drag and drop a file from your system into the box and release it here.

transcoding-input-drag-drop-video.png

Output Format

Select the Output Format of the file containers you want to create.  MP4 & TS are a video containers they can contain more than one file, usually a video file and audio file.  StreamEngine allows multiple files within each video container. 

output format with no numbers.png

transcoding onput format with numbers.png

1.) MP4

MP4 (MPEG-4 Part 14) is a digital container format that stores and plays back video and audio content. It's one of the most widely used formats for streaming and playing back videos
online.

2.) TS

Transport Stream file, is a type of digital container format used to store and stream video and audio content. It's a packetized elementary stream (PES) that carries multiple streams of data, including video, audio, and metadata.

DASH, HLS and DASH+HLS

These options will make a bunch of little video files and corresponding audio files, you will be required to select separate audio and should use tar file format which is similar to zip.  If you are on Windows you can download free open source 7-zip program. this allows a standard webserver the ability to stream the video, play it faster with less lag time and allow people playing the videos to quickly jump around or use an index into the video within seconds.   Normal videos still work but they are slower to start and rewind of fastforward until the full video file gets downloaded.  To learn more check out our API section on HTML+DASH+HLS.

3.) MP4+DASH

MP4-DASH (MPEG-4 Dynamic Adaptive Streaming over HTTP) is a digital container format that combines the benefits of MPEG-4 (video and audio encoding) with the adaptive streaming capabilities of DASH (Dynamic Adaptive Streaming over HTTP).

4.) MP4+HLS

MP4+HLS (MPEG-4 + HTTP Live Streaming) is a combination of two popular digital container formats: MPEG-4 for video and audio encoding, and HLS (HTTP Live Streaming) for adaptive streaming over HTTP.


5.) MP4+DASH+HLS

MP4+DASH+HLS (MPEG-4 + Dynamic Adaptive Streaming over HTTP + HTTP Live Streaming) is a combination of three popular digital container formats: MPEG-4 for video and audio encoding, DASH for adaptive streaming over HTTP, and HLS for efficient packaging and segmentation. This format allows for the creation of highly adaptable and efficient streaming experiences.

Separate Audio

image.png

This is set to No by default so the video container will have audio embedded in it, but if you would like to separate audio track from the video and get two separate files select Yes and you will get separated video and audio files.  If you have a lot of videos and audio files you may want to select tar option to bundle all of the files together.  On windows you may need the free 7-zip program to export a tar file. 

Select Yes to separate the video and audio files, you will not be prompted to add audio to the video profiles below.  

Select No to embed audio into the video file container, you will have the option under video profiles to add the audio you want in the source stream location you want.

Common Output Settings

This is where you can specify how your output location, settings and if the picture needs to be transformed.  By default we keep the video in the igolgi-store, which allows you to preview it in a browser (assuming you have the playback codecs) download and save the file.  You can also save your converted video in the cloud using AWS, Oracle or Google Cloud.   You have three different output codecs to use AHC/H.264, mpeg2 or HEVC/H.265.   You also have three choices for Picture Transform, none, deinterlace and deinterlace/detelecine.

transcode-common-output-numbered-1only.png

options 


Temporary Storage (1.)

igolgi-store

Igolgi store is the default setting for Common Output Setting, Cloud Provider.   StreamEngine will save your output files for up to 24 hours giving you time to view, download to save them. 

Cloud Providers (1.)

We are not going to cover cloud settings in great detail because we covered them above.    If you are using different cloud services we would recommend saving a template so you can refer back to them.

transcoding-cos-copy.png

1.) If you are using the same cloud service for input and output you can copy your settings from input to output so you don't have to re-enter your credentials. If you have different clouds for input and output you will not see the copy credentials option.

AWS

transcoding-cos-aws-1-2.png

In the example above aws was used for storage in file input so we can copy our settings without having to re-enter them again.

1.) Select AWS (or the same cloud service you used for file input location).

2.) Select copy credentials to copy settings from the input settings to output setting.

Oracle

transcoding-cos-oracle-numbers.png

The form example above is oracle cloud for file output but since oracle cloud for input was not selected you will not be able to copy oracle settings from input to output and you will need to  enter them in this form.

1.) If using Oracle Cloud Infrastructure (OCI) select oracle in the pull down.  
2.) Paste your Access Key into the Access Key field.
3.) Paste your Secret Key into the Secret Key field.
4.) Paste your tenancy ocid into the Tenancy OCID field, it may start with ocid1.tenancy.oc1
5.) Paste your user ocid into the User OCID field, it may start with ocid1.user.oc1
6.) Paste your oci fingerprint into the Fingerprint field, it should have colons (:) inside of it.
7.) Select the Region in the drop down list.
Optional - Save this as a template so it remembers your settings.

Google Cloud


transcoding-cos-gcloud-numbersv2.png

In the example above gcloud is selected for file input and you could copy credentials from the input to output, but you also have the opportunty to use different cloud accounts on the same cloud provider.  This would be good copying videos from your production house to a vendors cloud account.  In the case above you will need to fill out the information.

1.) If using Google Cloud (gcloud) select gcloud in the pull down.  
2.) Paste your secret key into the Secret Key field. 
3.) Paste your project id into the Project Id field, it may start with gcloud
4.) Paste your client email into the Client Email field it may end in gserviceaccount.com
5.) Paste your client id into the Client ID field.
6.) Select the private key id in the Private Key ID field.
Optional - Save this as a template so it remembers your settings.

Common Output Settings Continued ...

transcode-common-output-numbered-2-3.png

1.) Video Codecs 

transcoding-cos-video-codecs-numbers.png

Video codecs are use to reduce the size and bandwidth of videos.  Raw uncompressed or low compressed videos are great for editing but would be almost impossible to watch on cable and impossible to watch over wireless devices today. Videos need to be compressed. The lower the bandwidth the lower the cost or more people you can support on your hardware.  Lower compressed videos are great for editing but not streaming. Of the three codecs we currently support, hevc / h.265 has the highest compression and lowest bandwidth, h.264 / AVC is good all around widely supported and good compression and low bandwidth.

1.) h.264

H.264 also known as AVC is the default, it is an industry standard video codec for streaming and web based video.  It has a good compression ratio to show high motion, high fidelity audio at low bandwidths.

2.) mpeg2

Is an older standard from the broadcasting industries and is best for live events.  It has a very low latency for linear video but not recommended for nonlinear video applications, indexing and quick search.  For mpeg2 we only support HD jobs, resolution less or equal than 1920x1080. Framerates supported for this codec are:

3.) hevc

Is a newer codec also known as h.265, it may need to be licensed.  It is available on most players, mobile devices and browsers.  It currently allows the best video compression rates.  It does take longer to compress and is slightly rate higher to transcode. 

2.) Picture Transform

transcoding-cos-picture-transform-numbers.png

Picture Transform options are used to convert interlaced or telecined video into progressive video.  

Interlaced video is a technique used in video displays where each frame is divided into two fields: one containing all the odd-numbered lines and the other containing the even-numbered lines. These fields are displayed in rapid succession, with the odd lines shown first, then the even lines, creating the perception of a complete image. This approach effectively doubles the frame rate, making motion appear smoother and reducing flicker, while using the same bandwidth as a non-interlaced signal.

This method was originally developed for analog television to optimize broadcast bandwidth while maintaining image quality. However, in modern digital displays, interlaced video is often converted to progressive scan (where each frame is shown in its entirety) to improve clarity and reduce artifacts, especially for fast-moving content.

1.) none

None is the default setting.   None will not modify the the input video format.  Therefore, if the input video is progressive the output will be progressive,  or if the input is interlaced the output will be interlaced, etc.

2.) deinterlace

This setting will convert interlaced input video into progressive video.  The streamengine algorithm for deinterlacing is an advanced motion compensated, multi-frame solution that minimizes distortions that can occur when deinterlacing. If content is not interlaced streamengine will not perform any conversions.

3.) detelecine/deinterlace

This setting will convert telecine content back to progressive and remove repeated fields.  The streamengine algorithm analyzes the input video first to detect the telecine pattern and find the repeated fields.  In a second pass the algorithm removes those fields.  

In the case that the input video does not have telecine, the algorithm will deinterlace the content.

The input telecine cadence (3:2, 5:4, etc) will be automatically detected (even in the case there are mixed cadences).

The output framerate will be reduced back to the original progressive frame rate.  A typical example is a 29.97 fps input video with 3:2 telecine will be reduced to 24 fps progressive.

The benefits of detelecine your video is that the video sequence will have fewer artifacts, and also will require 20% or fewer bits to encode since repeated fields are removed.

See an example of the streamengine detelecine algorithm here  https://streamengine.igolgi.com/#detelecine

If content is not interlaced or telecined streamengine will not perform any conversions.

Audio Profiles

The first pull down selection is setting the codec for the audio.  AAC is the default.

transcode-audio-profiles-codec-numbers-dialnorm2b.png

Choose a Codec

1.) AAC

AAC or advanced audio coding is the standard for streaming video replacing mp3 format.  For more information see you can visit Wikipedia Advanced Audio Coding (AAC).

2.) AC3 & Dialnorm

AC3 & Dialnorm is the standard codec for Dolby Audio.  If you select AC3 you will need to set a Dialnorm as well.  Dialnorm stands for dialog normalization is a decibel range for changing dialog audio signal between 0 and -31 dB.  If you are not an audio engineer with a target dB range, you can play around with setting starting with 0 dB for no change or visit Dolby.com. Please note that you need to have a license to rebroadcast Dolby content. More information is also available on Wikipedia Dolby Digital AC-3 or Wikipedia dialnorm. 

3.) MP2

MP2 is a codec used with mpeg and ts video formats which is used by the television and broadcasting industries.

transcode-audio-profiles-channels-numbers-w-downmix.png

Channels and Downmix to Stereo

1.) 2 channels

Two channels are the default for stereo, left and right channel.

2.) 6 channels

Six channels are for surround sound or 5.1 audio (Front: right, center, left; Rear: right, left; and a subwoofer).   This will not

3.) Downmix to Stereo

If your input video is 5.1 audio, you can convert it to 2 channel stereo by selecting 2 channels and setting Downmix to Stereo to Yes.

Note: If your input is 2 channel audio it will not automatically convert your audio to 5.1 channel audio if you set it to 6 channels.  You must remix the audio in an audio or video editor first.   If you have 5.1 audio and set to 2 channels without setting downmix to stereo to Yes, it will put the right channel on the center channel instead.

transcode-audio-profiles-source-stream.png

Source Stream 

Most videos only have one source of audio so 1 is the default.  However, professional videos can have to 8 separate audio tracks that can be at different formats or different languages.  StreamEngine allows professionals the ability to setup different audio profiles - 8 

transcode-audio-profiles-bitrate.png

Bitrate kbps

Bitrates vary from 32 kbps - 768 kbps, depending on audio codec selected this list may be different as some codecs do not have the fidelity of AAC.  MP2 and AE3 have a bitrate range between 64 kbps - 448 kbps. 

Add or delete profiles 

transcode-audio-profiles-add-delete-numbers.png

1.) Click the blue Audio Profile link to add a new audio profile, you can add up to 3 profiles.

2.) Click the garbage can to delete a profile. 

Video Profiles

Depending on options selected above the video profile selection options may vary.

transcode-video-profile-w-numbers.png

1.) Video Defaults

transcode-video-profiles-video-defaults.png

This setting allows you to select presets with defined resolutions.  You can settings if you need to, and if you want to reset them just choose a different option then choose the one you want.

1.)  Video Defaults is the default, you can manually configure your video using the form
2.) Passthrough keeps the incoming video resolution allowing you to add additional features, this is great for changing bandwidth, converting video codec, dash, hls, dash+hls, adding a logo or changing other advanced settings.
3.) PC1 small size, PC2 medium or PC3 or larger size videos for small display screens.
4.) SD1 or SD2 Standard Definition presets, Prior to High Def or HD TV SD was the standard.
5.) HD1 or HD2 High Definition preset, 720 and 1080
6.) 2K standard setting for 1440
7.) 4K standard setting for 4K output 2160

Ladders are presets that allow multiple video outputs. you can always modify these settings and delete profiles you do not need.

8.) SD Ladder - has 3 Standard Definition settings.
9.) HD Ladder - has 5 High Definition settings
10.) 2K Ladder - has 5 settings 2 PC, SD, HD, & 2K
11.) 4K Ladder - has 5 settings 2 PC, SD, HD & 4K

2.) Blue Pencil icon

Click this icon to see a list of common preset sizes you can choose from.  Eight (8) sizes from small screens to 4K. Selecting a larger resolution might require a higher bandwidth to be selected in the Bitrate field, if you need to increase the bitrate you will get a message prompting you to set at least a minimum bitrate speed.

3.) Width

Horizontal resolution of the video.  If the video is being played back in landscape this number is generally larger than height. If the video is being played back in portrait this number is generally smaller than height. 

4.) Height

Vertical resolution of the video.  If the video is being played back in landscape this number is generally smaller than height. If the video is being played back in portrait this number is generally larger than height.

5.) Bitrate in kbps

Bitrate is the video, is the total bandwidth of the video.  In general a higher number will be a higher quality video, but it will use a higher bandwidth than a lower bitrate video.  Higher resolution and action videos usually need a higher bandwidth than lower resolution and less action videos.  Note: audio bitrate is in addition to video bitrate settings.

6.) Framerate

This setting will not adjust the speed of how a video plays it only changes the frame rate. 

7.) Audio Profiles

Each video can have up to 3 audio profiles added to it.  These can be set in the audio profile setting above.  Specify what audio you want to use with the video configured above.   The first audio track is the default.

8.) Add Video Profile

Click on this to add another video profile.  You can have up to five (5) videos per submission.  You can also delete profiles by clicking on the garbage can icon at the end of the line although you must have at least one video profile.

transcode-video-profiles.png

If you selected to separate your audio from the video container you will see a simpler video profile (above) that will only ask settings about the video.

image.png

If you selected to embed the audio profile into each video container then you will have to specify which audio profile to add to which video (above).

video-profile-save-to-cloud.png

If you selected to embed the audio into the video container and use a cloud provider to save your output you will be prompted to give the output location of the video (above).   i.e. on aws s3://igolgi-se-out/filename   if you selected tar as an advanced output option you will nee

Each video profile has a corresponding audio profile (above in the audio profiles section).


Complex Audio and Video Settings 

When you are using multiple audio profiles and generating multiple videos in the UI it might be best to choose the create .tar file option which should zip all of these files together for one download file.  On windows you may need to use free 7-zip to extract the videos.

Curl Command

For advanced users we include a curl command option, click on curl command to expand it and click on copy to copy the curl command to a clip board.  Curl can be used in Windows command shell, windows PowerShell or Linux.  Once you configure what you want in the StreamEngine Transcoding page and copy the curl, you can paste it an run it in curl.  With a little scripting skills you can automate curl calls to convert your videos, but it helps to build a few templates on the ui and download them to modify on your windows, mac or linux pc.  We do have some curl examples in the API section of this document.

Advanced Settings

Click the Advanced drop down

transcode-advanced-num-w-goodbetterbest.png

1.) Logo URL

If you are a professional user and not a trial user you can add your own logo to your videos.  File must be .jpg or .png format, logo will be scaled and put in lower right hand corner.  url needs to be publicly available image, i.e. http://localhost/logo.jpg will not work.

2.) Audio Volume

Decrease volume to 0 or increase volume to 200, default is 100.

3.) Create .tar file

default is no, depending on the number of videos or using external you are creating you might want to bundle your job into one file.  If you are using cloud storage specify the file output name.  i.e. on aws s3://output-directory/videofilename and .tar or .tar.gz should be appended to your videofilename.

Video Coding Options


4.) Video Quality  (Only available if h.264 video codec is selected)

Good, Better, Best.  This allows you to adjust the video quality these changes have subtle differences on most video files.  If you are looking for lower bandwidth choose good if you need the best quality at highest bandwidth choose best.

5.) IP Distance 

Distance between i/P frames 2 is two seconds, faster action videos could be lower and slower action could be longer.

6.) GOP Length

GOP Group of Pictures default is 2   To learn more about setting GOP lengths click here.

7.) Aspect Ratio

Common resolutions and aspect ratios, 8K is currently not supported.

Resolution Common Name Aspect Ratio Pixel Size
SD 480p 4:3 640x480
HD 720p 16:9 1280x720
FHD 1080p 16:9 1920x1080
QHD 1440p or 2K 16:9 2560x1440
UHD 2160p or 4K 16:9 3840x2160
FUHD 4320p or 8K 16:9 7680x4320

transcode-advanced-aspect-ratio-1-8v2.png

1.) Passthrough 

Passthrough is the default it keeps aspect ratio and video orientation the same as the input video.

Changes to aspect ratios should have Video Profile, video settings set to Passthrough (see below) 

image.png

2.) Force 4:3

Force the aspect ratio to 4:3 which is the SD stand definition standard on older TV and CRTs as well as older computer monitors and some smaller displays.  640x480 is 4:3 while HD and higher is generally 16:9 or 1920x1080.  If a video was recorded in 16:9 it may look distorted when resized to 4:3.  If you are processing a lot of videos do a test first.

3.) Force 16:9

Force the aspect ratio to 16:9 which is HD 720p or 1280x720 and higher resolution on newer TV and monitors. If a video was recorded in 4:3 it may look distorted when resized to 16:9.  If you are processing a lot of videos do a test first.

4.) Invert Aspect Ratio

This will switch the aspect ratio from 16:9 to 4:3 or visa versa.

The settings below are usually for video recorded with mobile devices.  Either in portrait or landscape modes.  These settings may be changed in the future. 

5.) Rotate Counterclockwise

Rotate the video 90 degrees counterclockwise.    Holding a phone in portrait mode converting it to landscape mode.  This may make the video upside down, if so use clockwise instead.

6.) Rotate Clockwise

Rotate the video 90 degrees clockwise.  Holding a phone in portrait mode converting it to landscape mode.  This may make the video upside down, if so use counterclockwise instead.

7.) Rotate Counterclockwise & invert Aspect Ratio

Rotate the video 90 degrees counterclockwise and change the aspect ratio.

8.) Rotate Clockwise & Invert Aspect Ratio

Rotate the video 90 degrees clockwise and change the aspect ratio.

8.) Rotation Side Panel Transparency

When converting a portrait video to landscape side panels can be added to show.

9.) Closed captions

No (default) yes if video has closed captions.

Run Job 

Once all of your settings are set click the blue "Run Job" button, if there are any mistakes, a red message will appear above the button and the parts of the form that need to be filled will have a red box around them.  You might want to click the blue triangle at the top of the page to open all dialog boxes if you can't find the missing fields.

run-job.png

After you submit your job, you can disconnect, log out if you want and the project will continue to run unless it has an error.  After you submit a job you might see a brief message below in the lower left hand corner near the igolgi logo.  this lets you know that your job is being transcoded.

job is submitted.png

The first step is transferring your job from the server to the worker which will do the encoding, at this step about 25% of the bar will be used.

run status uploading and finding backend server.png

At this step the worker is transcoding your job, depending on jobs in the queue and size of your video this could be short or take a while.

transcoding-job.png

Once the transcoding is done your job will be transferred to igolgi-store (temporary storage) or a cloud resource if you used one.

3.png

Sometimes your job might seem to hang at 99% this usually with large dash, hls or dash+hls where their are lots of little files that need to be packaged together in a tar file.

Once your job has completed you might see that your job has completed.  It is possible in rare occasions when using tar files you may get a completed before the job has been fully uploaded.  In these cases look to make sure your job has finished and has a finishing time on the job history page. If the job does not have a time stamp it is still copying the tar file to the output location.

job completed.png

Job History

Overview

The job history page will keep track of all of the jobs you have run and the state of the jobs.  Its hard to estimate how long a job will take to run, sometimes they are fast and other times they are slow.  It depends on the size of the video and what needs to be done as well as other jobs in the queue.  Once you submit a job you don't have to stick around, you can disconnect or log off from StreamEngine

image.png

Job Id

This is the front end job id of the job that was run.  If you submit a job with our UI or CURL this is the only Job_Id you need.  If you are a developer using our API there are two Job_Id's one for front end and one for back end and both can be different, you will use the front end Job_ID to access the back end Job_ID.

State

This shows the current state of the job, it may be orange - ongoing, green -success, red - error or gray - abort

Progress

Progress jumps in large segments, initially it copies your video to the server at about 25%, then finds a back end server and moves it to the proper back end server this is about 1/2 done and is being transcoded, then it is about 95% done it copies the finished file to the location specified.

Started

This is the time stamp when you hit the run job button on the transcoding page. 

Finished

This is the time stamp when the job has been copied to the location you specify in on the transcoding page.

Seconds

This is the playing time of the video that was encoded in seconds.  A 90 minute video is  5400 seconds.  We bill on seconds depending on options you choose.  You will not be billed if your job does not run for some reason.

Charge

This shows how much it costs to process the video.  The prices shown may not be the same prices you get charged.  Pricing is subject to change at any time. 

Config 

The config section shows all of the options below:

Errors

If you get an error message you can hover over it to see what it might be and

API

Creating cURL Jobs

Creating Jobs


To create a job, use your API key along with a JSON payload matching the schema described in the tables above, and make an HTTP GET request like the following:

curl https://streamengine.igolgi.com/api/v0/job \
  -k \
  --request POST \
  -u 8e6f7a5bf90821a175338ce08be4b7ca:a \
  --header 'Content-Type: application/json' \
  -d '{
  "videoProfiles": [
    {
      "output": "",
      "width": 1024,
      "height": 768,
      "video_bitrate": 3500,
      "video_bitrate_mode": "cbr",
      "video_framerate": "1x"
    }
  ],
  "audioProfiles": [
    {
      "audio_bitrate": 256,
      "audio_channels": 2,
      "audio_codec": "aac"
    }
  ],
  "output_container": "mp4",
  "video_codec": "h.264",
  "input": "oci://yzwhip2gci7s/jey_test_bucket2/test_dir/moana_30_seconds.ts",
  "cloud_credentials": {
    "input": {
      "cloud_provider": "oracle",
      "access_key": "...",
      "secret_key": "...",
      "region": "ca-toronto-1"
    }
  }
}'

Retrieving a Sent Job

To retrieve a job, use your API key to make a GET request to the /api/v0/job/id endpoint, replacing id with the id of the job you wish to retrieve:

curl https://streamengine.igolgi.com/api/v0/job/1 \
  -u 8e6f7a5bf90821a175338ce08be4b7ca:

The response will look something like this:

{
    "status": {
        "tcode_progress": "0",
        "state": "ready",
        ... # additional fields
    },
    "config": {
        ... # your job configuration
    },
}

This allows you to retrieve the original configuration for your job, as well as check on its progress using the tcode_progress field.

Ruby Examples

Feel free to modify the following script for your environment.  To process the video, this script below assumes your job is on aws in an S3 bucket for input and output.  

require 'net/http'

request = Net::HTTP::Post.new(url.path, headers)
request.basic_auth(auth[0], auth[1])
request.body = data.to_json

response = http.request(request)

# Print the response content
puts response.body

Save the file as se-api-aws.rb or similar.

Run: 
ruby se-api-aws.rb

You may notice an error like this:
...error ... message: "The video bitrate for this profile and codec should set at a minimum of 2300."...

The error above means the video_bitrate variable in the code should be higher than 2300, it was already changed in the code above, but used as an example of the messages you might see.

When it runs correctly you might see something similar to this:
{"_auto_generated_id_":13453,..."updated_at":"2024-07-16T18:49:57.000Z"}

The Id number can also be found on the Job History page.

Stream videos with HTML-DASH and HLS

Why would I want to use hls or dash?
Dash and Hls are great for streaming large files and give the user the ability to jump around in the video, fast forward, rewind or jump to an index.  In the past you needed expensive streaming servers and serve videos using rtsp: or mms:

In StreamEngine convert a file you want to stream from a website to mp4-hls, mp4-dash or mp4-hls+dash.  This will create a tar or tar.gz file
DASH - Dynamic  Adaptive Streaming over HTTP

then copy the file to your webserver and name it playlist.m3u8 or modify the <source src = "playlist.m3u8" ... line below.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>HLS-DASH Player</title>
    <link href="https://vjs.zencdn.net/7.20.3/video-js.min.css" rel="stylesheet">
    <script src="https://vjs.zencdn.net/7.20.3/video.min.js"></script>
</head>
<body>
    <video-js id="my-video" class="video-js vjs-default-skin vjs-big-play-centered" controls preload="auto" width="640" height="360">
        <source src="playlist.m3u8" type="application/x-mpegURL">
    </video-js>

    <script>
        var player = videojs('my-video');
        player.play();
    </script>
</body>
</html>

This HTML file does the following:

  1. It includes the video.js CSS and JavaScript files from a CDN.
  2. It creates a video player using the video-js tag.
  3. It sets the source of the video to your playlist.m3u8 file.
  4. It initializes the video.js player and attempts to start playback.

To use this:

  1. Save this HTML code to a file (e.g., player.html) on your web server.
  2. Make sure your playlist.m3u8 file is in the same directory as the HTML file, or update the src attribute with the correct path to your playlist file.
  3. Access the HTML file through your web server (e.g., https://yourserver.com/player.html).

Note:

API

Curl - Check Job Status

When you submit a curl job you should get a response back from the StreamEngine server with the job id on it.  

Curl - Linux and Windows 

curl -u API_KEY:a -H "Content-Type: application/json" https://streamengine.igolgi.com/api/v0/job/<JOB_ID>

replace API_KEY with your StreamEngine API Key

replace <JOB_ID>

If you only want to see job status and have jq installed on linux you can run

curl -u API_KEY:a -H "Content-Type: application/json" https://streamengine.igolgi.com/api/v0/job/<JOB_ID> | jq ".status" 

$ curl -u API_KEY:a -H "Content-Type: application/json" https://streamengine.igolgi.com/api/v0/job/<JOB_ID> | jq ".status"

Note the job_id above (backend) will be different than is the  <JOB_ID> submitted which is the id of the frontend,

or

$ curl -u API_KEY:a -H "Content-Type: application/json" https://streamengine.igolgi.com/api/v0/job/<JOB_ID> | jq ".status.job_completed"

jq is available for Windows, use at your own risk, it's a separate install, AMD64 executable should work with intel. 

Windows cmd, note API_KEY blurred out.

curl - powershell-check-jobstatus.png

On Windows with PowerShell.  PowerShell is a little different curl works but -u option does not so we will need to write a program.

param(
    [Parameter(Mandatory=$true)]
    [string]$JobId
)

$url = "https://streamengine.igolgi.com/api/v0/job/$JobId"
$username = "API_KEY"
$password = "a"

$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username,$password)))

$headers = @{
    Authorization = "Basic $base64AuthInfo"
    "Content-Type" = "application/json"
}

try {
    $response = Invoke-RestMethod -Uri $url -Headers $headers -Method Get

    Write-Host "Status for Job ID: $JobId"
    Write-Host "Full status:"
    $response.status | ConvertTo-Json

    Write-Host "`nKey status fields:"
    Write-Host "State: $($response.status.state)"
    Write-Host "Job Completed: $($response.status.job_completed)"
    Write-Host "Tcode Progress: $($response.status.tcode_progress)%"
    Write-Host "Xfer Progress: $($response.status.xfer_progress)%"
}
catch {
    Write-Host "Error checking job status: $_"
}

save it to a file for example CheckJobStatus.ps1

Then you can run the script above.

.\CheckJobStatus.ps1 -JobID <JOB_ID>

Linux shell script if you want to store your API key an reuse it with a script.

#!/bin/bash

JOB_ID=$1

if [ -z "$JOB_ID" ]; then
    echo "Please provide a job ID as an argument."
    echo "Usage: ./check_job_status.sh <job_id>"
    exit 1
fi

echo "Checking status for job ID: $JOB_ID"

while true; do
    response=$(curl -s -u API_KEY:a -H "Content-Type: application/json" https://streamengine.igolgi.com/api/v0/job/$JOB_ID)
    status=$(echo $response | jq -r '.status')
    
    echo "Job status: $status"
    
    if [ "$status" = "completed" ]; then
        echo "Job completed!"
        break
    else
        echo "Job still in progress. Waiting 10 seconds before checking again..."
        sleep 10
    fi
done

Curl - Windows PowerShell

Here is another example on Windows in PowerShell

 .\CheckJobStatus.ps1 -JobId <Your-Job-ID>

param(
    [Parameter(Mandatory=$true)]
    [string]$JobId
)

$url = "https://streamengine.igolgi.com/api/v0/job/$JobId"
$username = "API_KEY"
$password = "a"

$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username,$password)))

$headers = @{
    Authorization = "Basic $base64AuthInfo"
    "Content-Type" = "application/json"
}

function Check-JobStatus {
    try {
        $response = Invoke-RestMethod -Uri $url -Headers $headers -Method Get
        return $response
    }
    catch {
        Write-Host "Error checking job status: $_"
        return $null
    }
}

Write-Host "Checking status for job ID: $JobId"

do {
    $result = Check-JobStatus
    if ($result -ne $null) {
        $status = $result.status  # Adjust this if the API response structure is different
        Write-Host "Job status: $status"
        
        if ($status -ne "completed") {
            Write-Host "Job still in progress. Waiting 10 seconds before checking again..."
            Start-Sleep -Seconds 10
        }
    }
    else {
        Write-Host "Failed to get job status. Retrying in 10 seconds..."
        Start-Sleep -Seconds 10
    }
} while ($status -ne "completed")

Write-Host "Job completed!"

Anatomy of a Video

When you look behind the scenes of a video on YouTube you will notice that each video has more than one video (in the example below, YouTube has 24 videos). Streaming video companies like YouTube, Netflix, Apple, Pluto and others need to support different devices with different bandwidths and screen resolutions.  If the internet gets too bogged down, video providers will step down to the next video at a lower bandwidth until a higher bandwidth is available.   

image.png

Most video files are actually containers.  mp4, avi, mov, mkv and flv are containers.  Containers can hold a lot of information, audio tracks in different languages, video, closed caption text files etc. 

Codecs are different from containers as they compress and decompress different file.  The word codec was even taken from compress and decompress.  Most popular codecs are h.264, h.265 or hevc, aac, mp3 and others vp9 is a youtube codec.

Tools like ffprobe and mediainfo allow you to see inside of a video container.  Most containers contain a compressed video and at least 1 audio track.

StreamEngine allows you to convert up to 8 audio tracks inside of a container.

Below is a video from the united nations with many different language tracks.

Here is what a .mov video container looks like with mediainfo, the following example has 4 - two channel audio tracks as well as 1 video track and 1 other track.

Delta is an additional cost that will be added to the video size and format above.   If your video bandwidth is higher than 25,000Kbps there will be an additional fee, although 20,000Kbps is good for 4K with 5.1 surround.  Please note setting video bandwidth to 25,000 and audio to 256kbps would exceed 25,000.  A better setting would be to top out video at 24,000Kbps and use any audio setting. 

Beyond the Enterprise Plan you might want to consider igolgi hardware solutions for your organization.  Streamengine is based on iLux File and Blazar products.

While we can compress videos to Dolby format audio you will need a separate license from Dolby to broadcast or stream Dolby content.  Click to learn more about Dolby Audio Licensing

Using Tar

Some of the professional options of StreamEngine allow you to create several to thousands of video files, for these options we recommend using tar (tape archive) or adding all files to one big file which can be compressed. tar.gz is the compressed version of tar tar.gz which is similar to windows .zip files.  Most versions of Windows support tar and newer versions support tar.gz, however, windows tar is only accessible in from the command line.   There is a free open source tool called 7 zip which can be downloaded as well.

Selecting Tar as an options

Save as tar, tar is a compressed file similar to zip but for Linux, macOS and Windows 11 update 23H2 or higher.  You can open a tar file in Windows 10 using command line or you can use a third party app like free opensource 7-zip found at https://www.7-zip.com . 

Tar on Windows

On Windows 10 & 11
1.) Search for cmd
2.) Select Run as Administrator

You may get a popup windows asking "Do you want to allow this app to make changes to your device?", if so click Yes.

A command window will popup, navigate to the directory where the tar file is.

Then run tar -xf  tarfilename.tar and it will extract the file into the current directory.
In the example in the image above we ran tar -xf test.tar and it extracted 3 files from the tar file and put them in the current directory.

7-Zip on Windows 

1.) Search for 7-zip
2.) Click to download it
3.) Optional - Read more about 7-zip

Troubleshooting

If you get an error

image.png

On the job history page you may see this error ....  It is possible to use a video codec with streamengine that you do not have loaded on your computer, its also possible that your browser does not know how to play the video.  It's usually HEVC/H.265 that may be causing this issue.  HEVC/H.265 may require licensing some operating systems license it and some 3rd party player or video editors may license it as well. Use a Google or your favorite AI tool to search on how to get HEVC installed on your computer or browser.  When searching for errors it is best to be as specific as possible I can't play an H.265 video in Firefox v128 on Ubuntu 22.04. 

Also clicking on "Config" might give you clues as to what might be causing the playback problem.   The project was a success but the video won't play in the browser.  So the video file is good and you can click to download it and play it in a video player that supports the codec.  Although the video does not play in the browser so let's look for trouble shooting clues.  The video is on oci which is the oracle cloud and igolgi's temporary storage.  The audio codec is 'aac' which is pretty standard, the output container is mp4, but the video codec is HEVC which needs to be licensed.  Some computers and some browsers may be licensed and most mobile devices.
