A few things:

* You are replying to an email thread on the topic of YOP, yet you are
talking about BFI. It would be more appropriate to start a new thread.
Note that this does not mean replying to a message and changing the
subject line. Create a new message with a new subject and send it to the
list. It's less confusing.

* There is no demuxer in FFmpeg to handle BFI files. The first part of
your qualification task is to write a BFI demuxer. There is no
bfi_probe() function in the code. That's your job. Run 'ffmpeg -i' on a
supported file (like mpg, avi, mov) and you will see what kind of data
FFmpeg will output.
