We currently give ".mod" as a file name to ffmpeg when opening anything.
This allows playing amiga MOD files, which ffmpeg doesn't have a better
way to detect than the file extension. However, now MP3s are also detected
as MOD files and played with libmodplug, which has no idea how to handle
them.
I tried setting the parameter back to NULL, but then ffmpeg does not
detect any format at all and nothing is played.
Setting it to ".mp3", the decoding works fine again.
So, for things to work properly in as much formats as possible, we should
get either the MIME type or the file name to this function. Unfortunately,
we only get a BDataIO at that level. We can cast it to a BFile, but that
still doesn't get us to the filename, we would need a BEntry. An
alternative is to sniff the data to try to detect the file type.
