I need some help here !

I think I understood I don't have to change anything in the  
ByteIOContext structure ...
So whatever I have to do on the data, it has to be done on the  
AVPacket data, that's filled by the
get_partial_buffer method.

So if I need to skip some bytes, should I do a memmove on the data  
field of the packet ?
