    更新時間：Nov 25, 2024

    Obtains the upload URL and credential of a media stream.

    Operation description

    • You can call this operation to upload only a local media stream. After the media stream is uploaded, it is associated with the specified media asset ID.
    • You can call this operation to upload media streams only to ApsaraVideo VOD, but not to your own Object Storage Service (OSS) buckets. To upload a media stream to your own OSS bucket, you can upload the file to your OSS bucket by using OSS SDK, and then call the RegisterMediaStream operation to associate the media stream with the specified media asset ID.
    • This operation is available only in the China (Shanghai), China (Beijing), and China (Shenzhen) regions.
