    Viewing a mp4 file by mediaInfo,there are source frame count info and frame count info,and the frame count is larger than source frame count,also the Source duration is lager than Source_Duration_LastFrame correspondingly,who can tell me why?

    Usually, the source frame count (the raw stream) is larger than the track frame count (the tracks says it does not want the whiole raw stream).
    track frame count could be larger than source frame count if the tracks edit list has a kind of repetition.
    Or MediaInfo is totally wrong ;-).

    I need the file for analysis if you want something more precise.
