Event Name

ComposeMediaComplete

Event Description

If the application is configured with event notification, after a video is composed, the application backend can get an event notification through "normal callback" or "reliable callback". The content of the event notification is the ComposeMediaTask structure.

Samples

Normal callback

If you choose the normal callback mode, the callback URL will receive an HTTP POST request from VOD, whose content is in the BODY as shown below (the fields with null value are omitted):
