$ ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 output.mp4 |
does anyone know why I do not get any audio when I use ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 output.mp4
or ffmpeg -i input.mp4 -vcodec h264 -acodec mp3 output.mp4
?
I found a solution that works with ffmpeg -i input.mp4 -vcodec h264 -acodec copy output.mp4
but it does not solve the problem with the audio converting and I would really like to know what's the problem with the audio
tbh I got a pretty niet 650M file out of 2.7G
ffmpeg -i video.MOV -c:v h264 -c:a aac -strict -2 -pix_fmt yuv420p -q:v 0 video.mp4
I convert mov to mp4 and the result is good enough: 985 mb -> 358mb
ffmpeg -i video.mp4 -vcodec libx264 -crf 23 -preset medium -acodec aac -b:a 128k video-compressed.mp4
Next i want to compress it, got: 360 mb -> 302 mb
ll video*

ffmpeg is video compression software (among many other things), as far as I can tell the only difference is that you run it from a command line instead of a GUI, and it's free.
