In the job management module, you can quickly submit individual processing jobs for media files stored in OSS. These jobs include transcoding, snapshots, intelligent thumbnails, video moderation, media fingerprinting, and smart tags. This topic describes how to create and submit these jobs, and how to view their status and details.

Prerequisites

  • Set an input Bucket and an output Bucket. For more information, see Add media Buckets.

  • Enable the required pipeline based on the job type. For more information, see Enable a pipeline.

  • Optional: Create a template. If preset templates do not meet your business requirements, you can create a custom one. For more information, see Transcoding templates.

Limitations

The maximum size of an input file is 100 GB. Jobs fail if the file size exceeds this limit.

Create a transcoding job

This section describes how to submit a single transcoding job in the console. You can create a transcoding job to convert a video file into formats suitable for playback on various platforms. For a quick overview of the process, see Quickly submit a transcoding job.

Note

You can also submit a transcoding job by calling the SubmitJobs operation, or configure a workflow to automatically start multi-node transcoding jobs after a file is uploaded. For more information, see Get started with workflows.

  1. Log on to the MPS console.

  2. In the top navigation bar, select a region from the drop-down list.地域

  3. In the navigation pane on the left, choose Job Management.

  4. On the Encode tab, click Create Task.

  5. Configure the job parameters.

Parameter

Description

Input File URL

Click Select. In the Bucket drop-down list, select a Bucket. The folders in the selected Bucket are displayed under Path. Select an input file from a folder.

Note

  • If no Buckets are available in the Bucket drop-down list, go to the OSS console and create a Bucket in the current region. For more information, see Add media Buckets.

  • If you select a Bucket and no files are available under the path, go to OSS and upload files to the current Bucket in the current region.

  • If prompted that OSS is not activated, activate the service in the OSS console. For more information, see Activate OSS.

  • If you encounter a role error or a permissions error, log on with your Alibaba Cloud account, go to the Resource Access Management (RAM) console, and grant the required OSS access permissions to your current RAM user. You can attach the AliyunOSSFullAccess policy to grant full permissions on OSS, or customize permissions as needed. For more information, see Create a RAM user and grant permissions.

Encoding Pipeline

Select a pipeline name from the drop-down list.

Note

  • If no pipeline is available in the drop-down list, enable a pipeline first. For more information, see Enable a pipeline.

  • The transcoding pipeline has a default concurrency limit of 200 jobs. This is a soft limit and depends on resource availability.

Output File Name

Enter a name for the output file. A file extension is required for all file types except M3U8. For example: example_video01.mp4.

Output Path

Click Select. In the Bucket drop-down list, select a Bucket. The folders in the selected Bucket are displayed under Path. Select a folder to use as the output path.

Note

  • If the output path is the same as the input path and you use a different output file name, the source file is not overwritten. If the file names are the same, whether the source file is overwritten depends on your OSS configuration. To prevent overwriting, see Prohibit overwriting objects with the same name (Java). After this configuration is applied, writing the transcoded file to OSS fails if its name is the same as the source file. We recommend using a different name for the output file.

  • For information about how to resolve other common issues, see the description of the Input File URL parameter above.
