Relationship between VOD and OSS
VOD provides the massive, fast, and elastic upload capability based on the OSS storage. The VOD upload SDK can implement multipart uploads by encapsulating the OSS SDK. You can also directly use the OSS SDK to upload files. The upload procedure is as follows:
Obtain the upload address and credential from VOD. The upload address is the OSS bucket address. This bucket is automatically allocated when you activate the service, which is specified by Region. This bucket is used as the input storage. The cross-domain settings, crossdomain.xml, and related permissions have already been configured. For more information, see Upload address and credential.
Use Base64 to parse the upload address and credential. The UploadAddress field contains the upload OSS bucket address, and the UploadAuth field contains the temporary access credential.
Call the OSS SDK to upload the original video files to the specified bucket. After the upload is complete, the video files are automatically transcoded. You can configure a callback to receive notifications such as the transcoding completion notification.
