ApsaraVideo VOD supports the manual review feature. We recommend that you use the automated review feature to review videos on media platforms. Then, perform manual reviews only on files that contain suspected violations. This topic describes how to use the manual review feature and how to view the review history.
Overview
If you use the manual review feature, your files are reviewed by professional reviewers. This lets you detect and block illegal and non-compliant videos in advance or take them offline. This reduces the adverse impact caused by illegal and non-compliant content.
Usage notes
The final moderation result of an audio or video file is determined by both the automated and manual moderation results. However, the manual moderation result always overrides the automated moderation result.
After media moderation, only audio and video files in the Normal state can be played. Audio and video files in the Flagged or Reviewing state can be played only in the ApsaraVideo VOD console or using a security IP for moderation. You cannot obtain playback addresses for these files using an API or SDK. However, any valid playback addresses that have already been exposed can still be used for playback.
Prerequisites
ApsaraVideo VOD is activated. For more information, see Activate ApsaraVideo VOD.
You must upload the audio and video files to the Video-on-Demand (VOD) media asset library for review. For more information, see Media Upload.
Step 1: (Optional) Configure event notifications
We recommend that you configure event notifications in ApsaraVideo VOD before you perform manual reviews on media files. This way, you can obtain information such as review status and results from the callbacks after the files are reviewed. For more information about how to configure event notifications, see Configure callbacks.
The event that related to manual review is CreateAuditComplete.
