    Hi,
    How was the vod file created?

    You may want to take a look at this article regarding suggestions for creating Wowza compatible vod files.

    thanks daren!!!
    I am using ffmpeg library to get RTP-H264 Stream and save to mp4 file. I can play with VLC (video lan) or mplayer. but no video display on VOD, with sample.mp4 is ok.
    what something wrong??
    Thanks!!!

    You're welcome!
    Please provide an example of the ffmpeg command line you are using currently.

    What I really need to know is are you just saving directly from a stream to an mp4 file,
    or are you re-encoding the video and/or audio? But the command you are using should hopefully tell me.

    In the meantime I would try adapting the ffmpeg lines provided in the article I highlighted / linked to above
    to see if re-encoding fixes the problem.

    Hi,
    It's more likely to be a problem with the atom structure of the file and not the encoding profile or level.
