Note

This operation does not upload auxiliary media assets. To upload an auxiliary media asset, you must obtain the upload URL and credential, decode the URL and credential by using the Base64 algorithm, and then use OSS SDKs to upload the auxiliary media asset to a specified bucket. This process is the same as that of uploading a video or an image.
If the upload credential expires after 3,000 seconds, you can call the CreateUploadAttachedMedia operation again to obtain a new upload URL and a new upload credential.
If you enable the URL signing feature of ApsaraVideo VOD, you may be unable to access the returned URL of the media asset by using a browser and the HTTP status code 403 may be returned. You can disable the URL signing feature or generate an authentication signature.
For more information, see Upload URLs and credentials.
