vod callback settings

HTTP form callback) Continued upload a video, you found a problem when Ali goes over there to set up video transcoding, if the upload is complete you immediately go to get video information, the video will return you still can not get video transcoding information, Ali looked callback api write callback, the callback when the video transcoding after the success of data to fill in the video information
to note if you set up a callback URL authorization, he will send two "X-VOD-TIMESTAMP "," X-VOD-SIGNATURE " this is to prevent someone malicious brush your link
URL link authentication api
callback event type api link

on the code:

AliyunVideoUtils.callbackUrl // this is where you set the callback url
