APIs
Retrieve a task
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
ID of the task
Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Path Parameters
ID of the task
Response
Task ID
Type of the task
upload, export, export-data, transcode-file, clip Timestamp (in milliseconds) at which task was created
Timestamp (in milliseconds) at which the task was scheduled for execution (e.g. after file upload finished).
ID of the input asset
ID of the output asset
ID of the requester hash(IP + SALT + PlaybackId)
Parameters of the task
Parameters for the upload task
URL of the asset to "upload"
Decides if the output video should include C2PA signature
Restricts the size of the output video using the constant quality feature. Increasing this value will result in a lower quality video. Note that this parameter might not work if the transcoder lacks support for it.
H264Baseline, H264Main, H264High, H264ConstrainedHigh H.264, HEVC, VP8, VP9 How many seconds the duration of each output segment should be
Parameters for the export task
custom URL parameters for the export task
URL where to export the asset
Method to use on the export request
Headers to add to the export request
Parameters for the export-data task
File content to store into IPFS
Custom credentials for the Piñata service. Must have either a JWT or an API key and an API secret.
Name of the NFT metadata template to export. 'player' will embed the Livepeer Player on the NFT while 'file' will reference only the immutable MP4 files.
file, player Additional data to add to the NFT metadata exported to IPFS. Will be deep merged with the default metadata exported.
Optional type of content
Optional ID of the content
Parameters for the transcode-file task
Input video file to transcode
URL of a video to transcode, accepts object-store format "s3+https"
Storage for the output files
URL of the output storage, accepts object-store format "s3+https"
Output formats
HLS output format
Path for the HLS output
MP4 output format
Path for the MP4 output
Restricts the size of the output video using the constant quality feature. Increasing this value will result in a lower quality video. Note that this parameter might not work if the transcoder lacks support for it.
H264Baseline, H264Main, H264High, H264ConstrainedHigh H.264, HEVC, VP8, VP9 How many seconds the duration of each output segment should be
unverified Decides if the output video should include C2PA signature
URL of the asset to "clip"
Strategy to use for clipping the asset. If not specified, the default strategy that Catalyst is configured for will be used. This field only available for admin users, and is only used for E2E testing.
The start timestamp of the clip in Unix milliseconds. See the ClipTrigger in the UI Kit for an example of how this is calculated (for HLS, it uses Program Date-Time tags, and for WebRTC, it uses the latency from server to client at stream startup).
The end timestamp of the clip in Unix milliseconds. See the ClipTrigger in the UI Kit for an example of how this is calculated (for HLS, it uses Program Date-Time tags, and for WebRTC, it uses the latency from server to client at stream startup).
The playback ID of the stream or stream recording to clip. Asset playback IDs are not supported yet.
Force to use a specific strategy in the Catalyst pipeline. If not specified, the default strategy that Catalyst is configured for will be used. This field only available for admin users, and is only used for E2E testing.
catalyst, catalyst_ffmpeg, background_external, background_mist, fallback_external, external ID of the session
ID of the input asset or stream
Status of the task
Phase of the task
pending, waiting, running, failed, completed, cancelled Timestamp (in milliseconds) at which task was updated
Current progress of the task in a 0-1 ratio
Error message if the task failed
Number of retries done on the task
Output of the task
Output of the upload task
Type of the asset.
video, audio The playback ID to use with the Playback Info endpoint to retrieve playback URLs.
URL for HLS playback. It is recommended to not use this URL, and instead use playback IDs with the Playback Info endpoint to retrieve the playback URLs - this URL format is subject to change (e.g. https://livepeercdn.com/asset/ea03f37e-f861-4cdd-b495-0e60b6d753ad/index.m3u8).
The URL to directly download the asset, e.g. https://livepeercdn.com/asset/eawrrk06ts2d0mzb/video. It is not recommended to use this for playback.
Whether the playback policy for an asset or stream is public or signed
public, jwt, webhook ID of the webhook to use for playback policy
User-defined webhook context
Interval (in seconds) at which the playback policy should be refreshed (default 600 seconds)
List of allowed origins for CORS playback (<scheme>://<hostname>:<port>, <scheme>://<hostname>)
url URL from which the asset was uploaded.
Gateway URL from asset if parsed from provided URL on upload.
unverified Developer-managed ID of the user who created the resource.
Requested profiles for the asset to be transcoded into. Configured
on the upload APIs payload or through the stream.recordingSpec
field for recordings. If not specified, default profiles are derived
based on the source input. If this is a recording, the source will
not be present in this list but will be available for playback.
Restricts the size of the output video using the constant quality feature. Increasing this value will result in a lower quality video. Note that this parameter might not work if the transcoder lacks support for it.
H264Baseline, H264Main, H264High, H264ConstrainedHigh H.264, HEVC, VP8, VP9 Name of the NFT metadata template to export. 'player' will embed the Livepeer Player on the NFT while 'file' will reference only the immutable MP4 files.
