NOTE : Several demuxers may be opened at the same time so
demuxers should NEVER rely on an external var to enable them
self. If a demuxer can't do any autodection it should only use
file_format. The user can explictly set file_format with the -demuxer
option so there is really no need for another extra var.
For conivence an option can be added to set file_format directly
to the right type (ex: rawaudio,rawvideo).
Also the stream can override the file_format so a demuxer wich rely
on a special stream type can set file_format at the stream level
(ex: tv,mf).
