FFmpeg Introspection

I accidentally used the main ‘ffmpeg’ binary as an input to itself. Its best guess is that it’s an MP3 container with MPEG-1, layer 1 audio data:
[NULL @ 0x1002600]Format detected only with low score of 25, misdetection possible!
[mp1 @ 0x1003600]Header missing
Last message repeated 35 times
[mp3 @ 0x1002600]max_analyze_duration reached
[mp3 @ 0x1002600]Estimating duration from bitrate, this may be inaccurate
Input #0, mp3, from 'ffmpeg_g':
Duration: 00:03:20.29, start: 0.000000, bitrate: 256 kb/s
Stream #0.0: Audio: mp1, 32000 Hz, 2 channels, s16, 256 kb/s
At least one output file must be specified
What an Easter egg it would be if the compiled binary could actually decode to something — anything — valid.

We had an idea on IRC once to add detection to common file formats an fail gracefully with an “informative” message…

How about an audio clip of Mans screaming at the user that they should have read the man page?
