To ensure service reliability and data security, MPS only supports CMQ callback notifications.
If you successfully uploaded a file but did not receive a notification containing the file transcoding result after a certain amount of time, possible reasons include:
MPS uses Tencent Cloud CMQ to send callback notifications containing the transcoding results. You need to activate CMQ in advance and create a queue before you can receive transcoding callback notifications. In addition, you need to grant MPS permission to write data into the queue. Then, you can set the corresponding queue parameters when creating a workflow in the MPS Console.
For CMQ-related usage and fee information, please see CMQ Cost Description.
