sox FAIL formats: no handler for file extension `mp4'

[sandeeppatel1986]

I have .mp4 file and a .wav file.

I am passing .mp4 as good file and .wav as bad file. I am getting correct offset value.
But, out.wav is not getting generated and I am getting this error.

sox FAIL formats: no handler for file extension 'mp4'

So, what are the supported formats for sync audio/video?

At least WAV, FLAC and Ogg Vorbis work for me.

Boring details:

• SoX is used to read good file and to write output. So everything that SoX can read should work for good file, everything that SoX can write — should work for output file (see sox --help-format all)
• both good and bad files are also read by ffmpeg. So everything that ffmpeg can read is supported (see ffmpeg -formats and ffmpeg -codecs)
