Video Compositing Completion
Last updated: 2022-10-26 17:20:53
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):{"EventType": "ComposeMediaComplete","ComposeMediaCompleteEvent": {"TaskId": "1256768367-ComposeMedia-f5ac8127b3b6b85cdc13f237c6005d8","Status": "FINISH","ErrCode": 0,"Message": "SUCCESS","Input": {"Tracks": [{"Type": "Video","TrackItems": [{"Type": "Video","SourceMedia": "5285485487985271487","AudioOperations": [{"Type": "Volume","VolumeParam": {"Mute": 1}}]}]},{"Type": "Audio","TrackItems": [{"Type": "Empty","EmptyItem": {"Duration": 5}},{"Type": "Audio","AudioItem": {"SourceMedia": "5285485487985271488","Duration": 15}},{"Type": "Audio","AudioItem": {"SourceMedia": "5285485487985271489","SourceMediaStartTime": 2,"Duration": 14}}]}],"Output": {"FileName": "Video composing effect test","Container": "mp4"}},"Output": {"FileType": "mp4","FileId": 5285485487985271490,"FileUrl": "http://125676836723.vod2.myqcloud.com/xxx/xxx/xxx.mp4"}}}
Reliable callback
If you choose the reliable callback mode, after the PullEvents API is called, an HTTP response in the following format will be received (the fields with null value are omitted).
{"Response":{"EventSet":[{"EventHandle":"EventHandle.N","ComposeMediaCompleteEvent":{"TaskId":"1256768367-ComposeMedia-f5ac8127b3b6b85cdc13f237c6005d8","Status":"FINISH","ErrCode":0,"Message":"SUCCESS","Input":{"Tracks":[{"Type":"Video","TrackItems":[{"Type":"Video","SourceMedia":"5285485487985271487","AudioOperations":[{"Type":"Volume","VolumeParam":{"Mute":1}}]}]},{"Type":"Audio","TrackItems":[{"Type":"Empty","EmptyItem":{"Duration":5}},{"Type":"Audio","AudioItem":{"SourceMedia":"5285485487985271488","Duration":15}},{"Type":"Audio","AudioItem":{"SourceMedia":"5285485487985271489","SourceMediaStartTime":2,"Duration":14}}]}],"Output":{"FileName":"Video composing effect test","Container":"mp4"}},"Output":{"FileType":"mp4","FileId":5285485487985271490,"FileUrl":"http://125676836723.vod2.myqcloud.com/xxx/xxx/xxx.mp4"}}}],"RequestId":"335bdaa3-db0e-46ce-9946-51941d9cb0f5"}}
