	Better than no one ;-)

	It don't work with audio only, I wouldn't have change it if it worked.
	To see you must try with a live stream, with a on disk sample it work
	without change but you will not like why it work. The reason is that
	the asf demuxer take packets without looking what sort is asked.
	So to use it as is we must check if it will found them or not before 
	calling it. It's the reason why I added this two stream counter.
	With file the "common part" try to get video packet and the "asf 
	part" load all audio packets until eof (it don't check what is asked
	it just put in the good buffer what it found), then the "common part" 
	return that no video packet were found and pass to audio packet 
	wich are all alredy loaded. With live stream you can't get eof so 
	it undefinitly wait for video packets wich will never come.
	So I saw only two ways, make big modif on the asf demuxer, or use
	the header to only load something that we are sure to find, this is
	what I done.

	I didn't find another way, ideas are welcome. I thaught it was
	ok because it's the way used when no audio is here (not a so
	good reason). Some parts can be jumped with some goto,
	but we will need a bunch of if(sh_video) anyway mainly
	because of the osd wich need some sh_video fields.
