CreateUploadMedia - Intelligent Media Services - Alibaba Cloud Documentation Center

Obtains the upload URL and credential of a media asset and creates information about the media asset.

Operation description

You can call this operation to obtain the upload URLs and credentials of audio and video files. You can also call this operation to obtain the upload URLs and credentials of images and auxiliary media assets.
Obtaining an upload URL and credential is essential for Intelligent Media Services (IMS) and is required in each upload operation.
If the video upload credential expires, you can call the RefreshUploadMedia operation to obtain a new upload credential. The default validity period of a video upload credential is 3,000 seconds.
After you upload a media asset, you can configure a callback to receive upload event notifications or call the GetMediaInfo operation to determine whether the media asset is uploaded based on the returned status.
The MediaId parameter returned by this operation can be used for media asset lifecycle management or media processing.
You can call this operation to upload media assets only to ApsaraVideo VOD, but not to your own Object Storage Service (OSS) buckets. To upload a media asset to your own OSS bucket, you can upload the file to your OSS bucket by using OSS SDK, and then call the RegisterMediaInfo operation to register the file in the OSS bucket with the media asset library.
This operation is available only in the China (Shanghai), China (Beijing), and China (Shenzhen) regions.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
