Detailed Description
VDPAU hardware acceleration has two modules.
- VDPAU decoding
- VDPAU presentation
The VDPAU decoding module parses all headers using FFmpeg parsing mechanisms and uses VDPAU for the actual decoding.
As per the current implementation, the actual decoding and rendering (API calls) are done as part of the VDPAU presentation (vo_vdpau.c) module.

This structure is used to share data between the libavcodec library and the client video application.
The user shall zero-allocate the structure and make it available as AVCodecContext.hwaccel_context. Members can be set by the user once during initialization or through each AVCodecContext.get_buffer() function call. In any case, they must be valid prior to calling decoding functions.
