[MPlayer-dev-eng] [PATCH]demus_asf.c : ASF video not playing

[alexis.deruelle]

There's a bug in libmpdemux/asf_demux.c that prevents some videos 
(grabbed with my digital camera) from playing. 
 
The packet pointer calculation at the begining of demux_asf_fill_buffer 
is broken IMHO, the logic tries to adjust the pointer value with the 
size of optional ECC info. 
 
The simple patch below fixes it for me (against current CVS snapshot) :

             unsigned char segtype=p[1]; 
 
If no ECC is present, there's no need to offset the ponter at all. 
moreover the offset 
 
What do you think ?
