Otomatisasi pengambilan metadata media melalui BatchGetMediaInfos-ApsaraVideo VOD-Alibaba Cloud - ApsaraVideo VOD

Mengambil informasi dasar dan informasi file sumber untuk beberapa aset media.

Deskripsi operasi

You can retrieve information for up to 20 audio or video files in a single request.
The media asset information is generated asynchronously because Video on Demand (VOD) analyzes the source file after it is uploaded. You can configure event notifications for Audio/Video Analysis Complete. After you receive the notification, call this operation to retrieve the audio or video information.
