Make vaapisink expose only the set of supported caps for raw YUV buffers. Add gst_vaapi_uploader_get_caps() helper function to determine the set of supported YUV caps as source (for images). This function actually tries to zero and upload each image to a 64x64 test surface. Of course, this relies on VA drivers to not claim success if vaPutImage() is not correctly supported.
