When we use -c:a copy, no re-encoding is done on the audio track.When the -pix_fmt yuv420p argument is specified, 4:2:0 subsampling is used, a widely used and supported pixel format.The -c:v libx264 argument tells FFmpeg to use H.264 video compression.$ ffmpeg -i input.mp4 -c:v libx264 -pix_fmt yuv420p -c:a copy output.mp4 Here's how to convert any video to H.264, a format that's mostly associated with MP4.

For this tutorial we'll use FFmpeg 5.1.2, but any recent version will do.

It's also a very robust solution for implementing video automation, as we use it extensively in our own video editing API. It definitely contains both video and audio.ĭoes anyone have any advice on how to convert these files - I suspect that millions of people have these cameras (mine is made or oem'd by Golbong but I suspect others are using this format too judging by a bit of googling).FFmpeg is a free and open-source video editing tool capable of trimming, cropping, concatenating, muxing, and transcoding almost any type of media file you throw at it.

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.
