Description Andres 2019-02-25 22:57:10 UTC 
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?
