I am trying to convert a MKV into m4p using Windows, every time I do it has issues with codec. Which line of code canI I use which will work?
I have tried for %%a in ("*.mkv") do ffmpeg.exe -i "%%a" -vcodec copy -acodec copy "%%~na .mp4"
but no luck and ffmpeg -i input.mkv -c:v copy -c:a copy output.mp4, again, no luck
Please help :)
