What I think is going on here is that the format they are using is proprietary (I read somewhere that this could be to avoid licence fees). Output file #0 does not contain any stream Stream #0: not enough frames to estimate rate consider increasing probesize Format h264 detected only with low score of 1, misdetection possible! The following shows the command and relevant output:įfmpeg -i atest.h264 -c:a copy -vn -sn ffatest.m4a I tried the solution above but the audio extraction doesn't work and I get lots of error messages and no output file. I then discovered ffmpeg and found I could convert these files usingįfmpeg -r 12 -i atest.h264 -c copy ffatest.mp4 I also really need a way of batching the conversion of all the files which I am sending to an ftp server.

videoconver lacks any documentation and delivers video which runs at double speed. h264 and until recently, the only way I had found to convert them to a format I could play on Windows was using software they supplied (videoconver.exe) to convert to mp4 (video and sound). The camera records files with the extension. Hi, I am trying to convert files from a Chinese manufactured birdbox camera which also has a microphone.

Ffmpeg convert h264 to h265
