On the Tasks page of the ApsaraVideo Media Processing (MPS) console, you can submit a job with a few clicks to process a media file stored in Object Storage Service (OSS). For example, you can submit a job for transcoding, snapshots, video moderation, or media fingerprinting. This topic describes how to create and submit a job, and how to view the status and details of a job after the job is submitted.
Prerequisites
- The input media bucket and output media bucket are specified. For more information, see Add media buckets.
- An MPS queue is activated based on the job type. For more information, see Manage MPS queues.
- Optional: A template is available. If preset templates cannot meet your business requirements, you can create a custom template. For more information, see Transcoding templates.
Limits
The maximum size of a file that a job can process is 100 GB. If the file size exceeds the upper limit, the job fails.
Create a transcoding job
This section describes how to create a transcoding job in the MPS console. You can create a transcoding job to transcode a video into different formats that are suitable for playback on various platforms. For more information about the complete process of submitting a transcoding job, see Submit a transcoding job.
Note You can call the SubmitJobs operation to submit a transcoding job, or you can configure a workflow so that multiple transcoding jobs can be automatically initiated after a file is uploaded. For more information, see Use a workflow.
