            Bug ID: 109783
           Summary: YUV422 support not advertised for
                    VAProfileJPEGBaseline decoding
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: andrescj@chromium.org

Hi. I'm trying to detect the VAAPI JPEG decoder capabilities using
vaQueryConfigAttributes(). I'm getting VA_RT_FORMAT_YUV420 as the only value
for VAConfigAttribRTFormat when the profile is VAProfileJPEGBaseline and the
entrypoint is VAEntrypointVLD. However, based on [1], it seems that the JPEG
decoder would be happy to decode YUV422 images (in fact, YUV422 decoding works
when I call vaCreateSurfaces() with VA_RT_FORMAT_YUV422).

Note that when I use vaQuerySurfaceAttributes(), I only get NV12 for
VASurfaceAttribPixelFormat, so YUV422 is also not advertised there.

Is this intended behavior?
