vaapidecode: negotiate p010 (1.54 KB, patch)

Description sreerenj 2015-12-08 15:47:44 UTC
The main intention is to support downloading hevc-10 bit decoded surfaces.

P010 (16 bits per channel, interleaved U-V plane , set lowest 6 bits to zero)
is the native format picking by the vaapi-intel-driver for chroma format VA_RT_FORMAT_YUV420_10BPP

Right now,
1: No support for P010 video format in GStreamer
2: No support for P010 vaGetImage()/vaPutimage() in vaapi-intel-driver
3: As a result of 1&2 , we have no support for Vaapi Video memory mapping
       through GstVideoMeta.

BPP for VAImageformat should be 24 i guess, check the driver source code..

vaapidecode: negotiate p010

This should be on top of patches in,

I am just adding patches here for reference, we can push after the 1.8 release, also have to push the P010 support patch in gst-plugins-base first.

Pushed with slight change in bpp for aligning with driver. Thanks for the patch

    Add P010 video format support
    The P010 video format is the native format used by the vaapi intel driver
    for HEVCMain10 decode . Add support for planes and images of this video format.

As a result of the following patch, vaapidecode's default src pad format will become NV12 instead of I420 in most of the usual decode scenarios. And will negotiate P010 for 10 bit formats.

    vaapidecode: Use video format derived from decoded surface as default src pad format
    Use the surface format derived from first decoded surface
    to negotiate the downstream video format capabilities.
