[FFmpeg-devel] [PATCH]Add function pointer struct to vdpau.h

[Carl Eugen Hoyos]

Hi!

All vdpau using applications, inside and outside ffmpeg, (will) need a set 
of function pointers to use vdpau functions.
Attached patch aims at reducing possible code duplication by defining a 
struct containing all function pointers.

Please comment, Carl Eugen
