This is the alphaless version of VUYA that I introduced recently. After further discussion and noting that the Intel vaapi driver explicitly lists XYUV as a support format for encoding and decoding 8bit 444 content, we decided to switch our usage and avoid the overhead of having a declared alpha channel around. Note that I am not removing VUYA, as this turned out to have another use, which was to replace the need for v408enc/dec when dealing with the format. The vaapi switching will happen in the next change Signed-off-by: Philip Langdale <philipl@overt.org> --- libavutil/pixdesc.c | 12 ++++++++++++ libavutil/pixfmt.h | 2 ++ libavutil/tests/pixfmt_best.c | 1 + tests/ref/fate/imgutils | 1 + tests/ref/fate/sws-pixdesc-query | 3 +++ 5 files changed, 19 insertions(+)
