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.

#define FF_API_BUFS_VDPAU 1

#define FF_VDPAU_STATE_USED_FOR_RENDER 1

The videoSurface is used for rendering.

Definition at line 154 of file vdpau.h.

#define FF_VDPAU_STATE_USED_FOR_REFERENCE 2

The videoSurface is needed for reference/prediction.

The codec manipulates this.

AVVDPAUContext* av_alloc_vdpaucontext ( void )

allocation function for AVVDPAUContext

Allows extending the struct without breaking API/ABI
