Hi Nidaan,
For mp4 you would require H 264 codec. I have not tried mp4 conversion in ffmpeg .

Thanks,

ffmpeg -i -acodec libmp3lame -ab 160kb -ac 2 -ar 44100

The Above command executed and 0 byte mp3 file is created always. Can anybody tell me what might be the reason?

Thanks in advance.

Try “ffmpeg -i test.mp3 test.flv”

Hi Malli,
Converting from wav to mp3 using ffmpeg is straight forward: “ffmpeg -i test.wav test.mp3″

NOTE:
You need to have libmp3lame installed on your system and ffmpeg is compiled with libmp3lame enabled.

Thanks,
Hitesh Agarwal
