I had an old version of this patch which contains the following snippets, and tested it on my baytraili platform.
if (fourcc == VA_FOURCC('Y', 'V', '1', '6')) {
width[1] = obj_image->image.width / 2;
height[1] = obj_image->image.height;
width[2] = obj_image->image.width / 2;
height[2] = obj_image->image.height;
}
Yesterday, I found the previous version of this patch miss the snippets, so I noted the patch maker. Today, I found he had added the missing part, so I blindly +1 for this patch without careful review and retesting. Sorry.
