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.
