With a data processing workflow, you can quickly and flexibly create video processing processes as needed. A workflow is bound to a path of an input bucket. When a video file is uploaded to the path, the media workflow will be automatically triggered to perform the specified processing operation, with the processing result automatically saved to the specified path of the destination bucket.
You can use a data processing workflow to implement the following features: audio/video transcoding (including top speed codec and broadcast media format transcoding), video frame capturing, video to animated image conversion, intelligent thumbnail, audio/video splicing, voice separation, highlights generation, HLS adaptive multi-bitrate, SDR to HDR, video enhancement, super-resolution, audio/video segmentation, custom function, and image processing.
- Currently, workflows can process 3GP, ASF, AVI, DV, FLV, F4V, M3U8, M4V, MKV, MOV, MP4, MPG, MPEG, MTS, OGG, RM, RMVB, SWF, VOB, WMV, WEBM, MP3, AAC, FLAC, AMR, M4A, WMA, and WAV files. When initiating a media processing request, you must enter the complete file name and extension; otherwise, the format cannot be recognized and processed.
- Currently, the workflow feature can only manipulate video files being uploaded. To perform media operations on cloud data, use the job feature.
/. If it is not specified, the workflow will be triggered for all paths in the input bucket. After the media workflow is enabled, when a video file is uploaded to this path, the workflow will be automatically triggered.
Description: The intelligent thumbnail feature understands the video content with the aid of Tencent Cloud's advanced AI technologies to intelligently extract three optimal keyframes.
Description: The HLS adaptive multi-bitrate feature encapsulates multiple files with multiple bitrates and audio tracks into one multi-bitrate adaptive video file.
You can view the list of created workflows on the workflow management page.
The workflow list displays the names, IDs, input paths, creation times, and statuses of workflows. You can search for workflows by name and ID to view, edit, or delete specified workflows.
Workflows are disabled by default. To enable a workflow, click the toggle in the Enable column. Once enabled, the workflow will take effect in five minutes.
You cannot edit or delete an enabled workflow.
An execution instance will be generated after a workflow is executed for each video file. The execution instance page displays the source file address, workflow execution status, and execution time.
After a workflow is created, it can be automatically triggered for files uploaded to the specified bucket or manually triggered for existing files in the bucket.
Workflows support rendering destination file names and URLs with the following variables:
|InputName||Filename of the input file (without file extension)|
|InputNameAndExt||Filename of the input file (with file extension)|
|InputPath||File input path|
|RunId||Execution instance ID|
|Ext||Destination file format|
|Number||Destination file number|
If the names of your input files are
test2.mp4, and you want to convert them to the FLV format (the final filenames will be
test2.flv), then set the parameter format of the destination filename to
If the parameter format of the destination filename is set to
When the workflow generates two instances (
000002) during execution, the final filenames will be
