ffmpeg convert mp4 to mpg which can be played in a dvd player
17 avril 2014, par Santhosh YedidiI have seen that to convert a file to dvd player format using ffmpeg we use
ffmpeg -i input.mp4 -target ntsc-dvd output.mpgthe output.mpg will be played from usb in the tv.
But the bitrate at which ntsc-dvd converts is very high. Because of which the size of the mpg is 5 times bigger than mp4.
So i tried to convert manually
ffmpeg -i input.mp4 -c:v mpeg2video -q:v 5 -c:a ac3 -b:a 60k output.mpgthe problem is the file gets converted with almost equal size as mp4 but without any sound. The audio codec of output.mpg shows ac3. Why ac3 is not having any sound.
