Media Processing Service (MPS) is an on-cloud transcoding and audio/video processing service for massive amounts of multimedia data. You can write functions to process the callback information in MPS and dump, publish, and process relevant events and subsequent content in video tasks by receiving relevant callbacks.
Characteristics of MPS triggers:
WorkflowTask
) and video editing task (EditMediaTask
).When a specified MPS trigger receives a message, the event structure and fields will be as shown below (with the WorkflowTask
task as an example):
