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. ---

Jon, Take a look at codec info in GSpot: [https://www.wowza.com/docs/how-to-view-on-demand-file-details](https://www.wowza.com/docs/how-to-view-on-demand-file-details) It may not be h.264 video. Richard ---

Jon, I get the same error: “Atom size is invalid: 0”. Your encoding process is going wrong somehow. But I was able to fix it with ffmpeg just by doing this: ffmpeg -i c:\59418.mov -vcodec copy -acodec copy c:\out.mp4 Can you use Expression 4 instead?

Jon, The video is the problem with that one. The other one also had unsupported audio codec. I guess you can do ffmpeg post process to fix them. Richard ---

Hi, WE had the same issue and we find out that our video file was wrong because of the following - the first stream was audio - the second stream was video Which is not a correct usage! We swapped the stream and it worked fine! ---

Info on Atom size here: [http://wiki.multimedia.cx/index.php?title=QuickTime\_container](http://wiki.multimedia.cx/index.php?title=QuickTime_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. ---

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: [https://www.wowza.com/docs/how-to-install-and-configure-wowza-streaming-engine#supportedMedia](https://www.wowza.com/docs/how-to-install-and-configure-wowza-streaming-engine#supportedMedia) ---

> 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 ---
