Hi, This patch series fixes and optimizes support for H.grayscale streams encoded in H.264 (Patch8). This is backwards compatible with solutions that incorrectly request for YUV 4:2:0 formats instead of the appropriate Y800 one.
Tested with gstreamer-vaapi and FFmpeg/vaapi on Ivybridge. No regression. v2: split into smaller patches, while maintaining regression testability, drop dead code in the Y800 rendering code path. Regards, Gwenole Beauchesne (8): surface: fix geometry (size, layout) of grayscale surfaces. surface: factor out release of surface buffer storage. surface: fix vaDeriveImage() for grayscale. config: fix vaGetConfigAttributes() to validate profile/entrypoint. config: fix vaCreateConfig() to not override user chroma format. config: fix supported set of chroma formats for JPEG decode. decoder: h264: factor out allocation of reconstructed surfaces. decoder: h264: optimize support for grayscale surfaces. src/gen6_mfd.c | 20 ++- src/gen75_mfd.c | 18 +-- src/gen7_mfd.c | 18 +-- src/gen8_mfd.c | 18 +-- src/gen8_render.c | 3 + src/i965_decoder_utils.c | 75 +++++++++++- src/i965_decoder_utils.h | 8 ++ src/i965_drv_video.c | 301 +++++++++++++++++++++++++++++++--------------- src/i965_drv_video.h | 14 +++ src/i965_output_dri.c | 6 +- src/i965_render.c | 3 + 11 files changed, 326 insertions(+), 158 deletions(-) -- 1.7.9.5 _______________________________________________ Libva mailing list Libva@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libva
