Manage media files - ApsaraVideo Media Processing - Alibaba Cloud Documentation Center

The Media List page of the ApsaraVideo Media Processing (MPS) console displays the media files that are uploaded by using the MPS console or generated from workflows. You can search for, view, publish, unpublish, or remove media files on the Media List page. You can also manage media files by calling API operations.

Features

Feature	Description
Search by condition	You can search for a media file based on the time, file name, and video ID. The video ID is the ID of the media file.
View media information	A media file contains an input file, an output file, and related resources such as snapshots. Each media file has a unique ID. You can use the unique ID to search for the media file and view the information about the media file, including the Object Storage Service (OSS) storage paths and metadata such as the creation time, format, length, bitrate, frame rate, thumbnail size, and file size. Media information also includes the information about the nodes in a workflow. You can view the information about the nodes on the tabs such as Intelligent Thumbnail, Content Moderation, and Video DNA.
Publish or unpublish a media file	By default, the Published or Unpublished state of a media file depends on the settings of the Publish node in the relevant workflow. You can change the state of a media file in the MPS console. If a media file is published, the access permissions on all resources related to the media file, including playback resources and snapshots, are the same as those on the OSS bucket in which the media file resides. If a media file is unpublished, the media file can be accessed only by the current account.
Remove a media file	If you remove a media file on the Media List page, the file is not deleted from the OSS bucket in which the media file resides.
Update a media file	You can call an API operation to update the specified or all media files.
