It is, I added pos now.

In general, it is working quite OK in linear case (decoding), but 
something makes trouble when seeking in my keyframe finding routine I 
posted earlier today. Timestamps and positions from previous backward 
seek steps keep reappearing in new seek steps, even though the parser is 
reset after each av_read_frame sequence (which also resets st->cur_pkt). 
I don't quite get it where it comes from. Well, I'll have to analyse 

I'm just wondering, if the default buffer of 4 packets is going to be 
enough now.
