Hi, I am using WOWZA with Flowplayer. Today I have encountered a problem with some of the mp4 files. When I try to play these files I am getting this error: WARN server comment demo2\_0.mp4 MediaReaderH264.open[2]: java.lang.Exception: QTUtils.parseQTMediaContainer: File is missing ‘moov’ atom. WARN server comment demo2\_0.mp4 MediaReaderH264.open[2]: java.lang.Exception: QTUtils.parseQTMediaContainer: File is missing ‘moov’ atom. I have read some of the discussion here and applied … patch but this does not help. These files are not static files (that means content of these files are not getting changed or recorded live). Please suggest an way-out. Note: I have uploaded one such video in youtube.Please check that for reference.

How were these files recorded, exactly? With Wowza? What recording method? What is the source? Richard ---

I can’t get to those files because my anti-virus program says that site is known spyware site. Try using flv: prefix instead of mp4: Richard ---

I tested demo2.mp4. It appears to be h.264 video/AAC audio in a FLV container with a .mp4 prefix. I opened it in VLC and looked at Tools \> Codec info, which shows h.264 and AAC. Good so far, however… Then I played it back in Wowza SimpleVideoStreaming RTMP client with vod application and stream name “mp4:demo2.mp4”, which resulted in no playback and this error in Wowza logs: > QTUtils.parseQTMediaContainer: File is missing ‘moov’ atom. Then I played it back in Wowza SimpleVideoStreaming RTMP client with vod application and stream name “fly:demo2.mp4”, and it played back fine without error in client or Wowza server. I was able to fix it with ffmpeg: ```auto ffmpeg -i demo2.mp4 -acodec copy -vcodec copy new.mp4 ``` Richard ---

That file is using vp6 video and mp3 audio, according to VLC. You will have to transcode the video to h.264. Richard ---

Hi dbhattacharjee, You would have to re-encode to create the moov atom. Perhaps: ffmpeg -i input.mp4 -c:v copy -c:a copy output.mp4 More info here: [understanding-the-moov-atom-once-and-for-all](http://learnfromlisa.com/2010/10/understanding-the-moov-atom-once-and-for-all/) ---

Hi Richard, These files are not recorded but they are downloaded from different sites to test playback with WOWZA and Flowplayer. You can get one of the source file from here: [http://www.freefilehosting.net/demo2](http://www.freefilehosting.net/demo2) ---

I can’t use fixed prefix as ‘flv:’ as file extensions are dynamic in my case and I am targeting Ipad,Iphone etc. ---

I have uploaded sample file to Google Drive.

BTW,if these are corrupt files then how google is able to play them ? ---

Thanks for the detailed answer. 🙂 I am now able to play demo2.mp4. But when I try to apply same technique to demo.mp4 it fails. It seems there is some problem with codecs. can you please check ?
