RegisterMedia - Developer Guide| Alibaba Cloud Documentation Center

Description

You can call this operation to register media objects (including audios and videos) in OSS buckets that have access to ApsaraVideo for VOD. After a media object is successfully registered as a media asset, you can submit a transcoding or video snapshot based on the media ID.

Restrictions:

You can register a maximum of 10 OSS media objects that have the same storage location at a time.
After a media asset is registered, this operation does not automatically trigger a transcoding job if the transcoding template group ID is not specified. If the transcoding template group ID is specified, the system uses the specified template group to transcode the media asset. This processing is different from video upload.
If you submit a media object that has been registered, this operation returns only the unique media ID associated with the media object, without other processing.
