+  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).
