    Default Help with "Atom size is invalid: 0"

    WARN server comment xxxxxxxx\58654.mov MediaReaderH264.open[2]: java.lang.Exception: QTUtils.parseQTMediaContainer: Atom size is invalid: 0

    Our wowza server performs well and provides VOD rtmpe streams

    Recently we have had the above error with a particular batch of mov files.

    These are files exported directly from AVID

    Can anyone help me understand why these wont play?

    Thanks

    Jon

    So you're saying the problem happened one time and has since resolved itself? Maybe you had network problems that produced corrupted files. Or, maybe the device needed to be rebooted.

    No the problem is ongoing - with any file made from AVID.

    I am trying to understand what the error means.

    Jon,

    Take a look at codec info in GSpot:
    http://www.wowza.com/forums/content....o-audio-codecs

    It may not be h.264 video.

    Info on Atom size here: http://wiki.multimedia.cx/index.php?...Time_container

    That is just a WARN, not a fatal error. Try playing the file in the Wowza SimpleVideoStreaming example with or without the mp4 prefix: "mp4:filename.mov".

    If it still doesn't work, describe your setup, your file encoding, and post the output of your Wowza console or your access log from when you try to play the file.

    Thanks, what happens is that warning just repeats 1000 times down the page, the video does not play:

    narcosi,

    Thanks. The lines I'm looking for describe the codec, which would appear right when click play. Please post what the encoding/codec of the file is as Richard said using the GSpot or Mediainfo programs.

    Jon,

    It looks like your audio is encoded in Apple QuickTime IMA4. This is not supported by Wowza and would require transcoding to play on anything other than Quicktime. Take a look at the Quickstart Guide for a list of supported codecs:

    I will report back.
