Whisper api completely wrong for mp4

[jwatte]

@jwatte

If you use a library to transcode from mp4 to some other format/codec (mp3 or wav,) before you forward it to the Whisper model, does it work better?

@kwento

It definitely seems like the Whisper API is unable to understand mp4 file types encoded with mp4a.

So, if you use a library to transcode from mp4 tomp3 or wav, before you forward it to the Whisper model, does it work better?
