[FFmpeg-user] need help to convert wav to mp3

[Arif Driessen]

Looking at your output it looks like it can't figure out what your
input.wav is. Does your wav file work in other applications? Have you tried
increasing the value for 'analyzeduration'?
If you know the details you could manually specify them, something like:
ffmpeg -acodec pcm_s16le -i input.wav out.mp3 (it's likely going to be
pcm_s16le or pcm_s24le or pcm_s32le)

Perhaps you don't have these codec installed/enabled. You will want
something with PCM in it. Run: ffmpeg -codecs and look for anything with
PCM in it. On Linux, and possibly Mac, you could run: ffmpeg -codecs | grep
-e '\sPCM'
to filter for lines containing PCM for you.
