Event Name

ConcatComplete

Event Description

If the application is configured with event notification, after a video is transcoded, the application backend can get an event notification through "normal callback" or "reliable callback". The content of the event notification is the ConcatTask2017 structure.

Normal Callback

If you choose the normal callback mode, the callback URL will receive an HTTP request in the following format:

{
    "EventType":"ConcatComplete",
    "FileUploadEvent":null,
    "ProcedureStateChangeEvent":null,
    "FileDeleteEvent":null,
    "PullCompleteEvent":null,
    "EditMediaComplete":null,
    "WechatPublishComplete":null,
    "TranscodeCompleteEvent":null,
    "ConcatCompleteEvent":{
        "TaskId":"Concat-1edb7eb88a599d05abe451cfc541cfbd",
        "FileInfoSet":[
            {
                "ErrCode":0,
                "Message":"",
                "FileId":"14508071098244931831",
                "FileUrl":"http://125676836723.vod2.myqcloud.com/xxx/xxx/playlist.f6.m3u8",
                "FileType":"m3u8"
            },
            {
                "ErrCode":0,
                "Message":"",
                "FileId":"14508071098244929440",
                "FileUrl":"http://125676836723.vod2.myqcloud.com/xxx/xxx/f0.mp4",
                "FileType":"mp4"
            }
        ]
    },
    "ClipCompleteEvent":null,
    "CreateImageSpriteCompleteEvent":null,
    "SnapshotByTimeOffsetCompleteEvent":null
}

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.

{
    "Response":{
        "EventSet":[
            {
                "EventHandle":"EventHandle.N",

                "FileDeleteEvent":null,
                "PullCompleteEvent":null,
                "EditMediaComplete":null,
                "WechatPublishComplete":null,
