Dear all, Thanks for your response. I find that the output is mp2 if I use ffmpeg -i input.mp4 output.mp3. Of course, I can use lame to further convert the mp2 file to mp3. How can I achieve the same mp3 by one command?
I tried add the command mentioned by Sjoerd, but it says "Unknown encoder 'libmp3lame'", what package should I install to make it works? Thanks.
