Detailed Description

VDPAU hardware acceleration has two modules.

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.
