[Mesa-dev] [PATCH v5 05/10] st/va: add colospace conversion through Video Post Processing

Julien Isorce j.isorce at samsung.com
Fri Oct 30 04:42:48 PDT 2015


Add support for VPP in the following functions:
vlVaCreateContext
vlVaDestroyContext
vlVaBeginPicture
vlVaRenderPicture
vlVaEndPicture

Add support for VAProcFilterNone in:
vlVaQueryVideoProcFilters
vlVaQueryVideoProcFilterCaps
vlVaQueryVideoProcPipelineCaps

Add handleVAProcPipelineParameterBufferType helper.

One application is:
VASurfaceNV12 -> gstvaapipostproc -> VASurfaceRGBA
