vaQueryImageFormats missing packed RGB24 format in postproc

[HeJunyan]

Gstreamer

gst-launch-1.0 videotestsrc ! capsfilter caps=video/x-raw,format=RGB,width=800,height=600 ! vaapipostproc ! video/x-raw,format=NV12 ! filesink location=ppp.yuv

can not work, because the FOURCC of VA_FOURCC_R8G8B8 can not be found in current driver.

While, I checked, at least the version:

still have this support

Since driver cannot output R8G8B8, currently, we cannot separate the image capability for input and output, and we remove it in image capability immediately, but you still can use it as input.

Jister, please help to follow up this issue, thanks a lot in advance!

it is a limitation of caps reporting, could we close it or move it to libva @HeJunyan
