What is wrong with the following ffmpeg command
14 août 2013, par BradWhat is wrong with the following ffmpeg command. Originally this had -sameq instead of the -qscale:a 0
Command :
ffmpeg -loglevel debug -threads 4 -i sample-in.mpg -ss 00:00:01 -t 00:00:05 -f image2 -y sample-frames/frame%d.png -acodec copy -qscale:a 0 -y sample.mp3
