• Concat 2 H264 mov into mp4 using ffmpeg or other ?

  19 septembre 2013, par pixelwiz

  We recently bought a JVC GY-HM650U camcorder. One of the things it can do is record into a "web" format at the same time it records HD. However, the problem we've ran into is that it splits up the recording about every 30 minutes. I've contacted the manufacturer and they might fix the firmware in the future, but I need to do something about it now. So the camera produces an MOV file, but it's supposed to be a H.264 mp4 under the surface. I tried to follow the steps here : http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20concatenate%20%28join,%20merge%29%20media%20files but was not successful. I can either merge the two files into one mov, and if I try to play the MOV in JWPlayer for some reason I lose the audio. If I try to go into a .mp4 I get an error. I found some 3rd party software for joining video files without having to re-encode them if they are already encoded the same way, but none proved successful at producing a playable file with audio. Any suggestions ?
