    Default start time of the first .ts file is 10, but not 0, why?

    Hi,

    I stream mp4 videos over HLS/SMIL using url like http://serverort/vod/smil:test.smil/playlist.m3u8. I downloaded some .ts files, specified in the chunklist. With the help of ffplay, I can get the duration and start time of the .ts files. However, the strange thing I have seen in the first .ts file is that, it starts with time 10, but not 0 which is what I'm expecting. I've tried several different videos and the first .ts file of all videos starts with time 10.
    So, is there a setting in wowza server allowing me to make the start time of .ts files to be 0?

    I can confirm, ffprobe reports start:10.0 using first .ts file in the sample.mp4 chunklist. I am not sure exactly why but I can say that these chunks work as expected for HLS (cupertino) playback, and a single downloaded chunk plays back in VLC as expected. So it is not a bug and there is little chance it will change.
