According to spec, if we use VkBindImagePlaneMemoryInfo to bind image we mush create image with disjoint flag. The offset in subresourcelayout is relative to the base address of the plane, but the offset in drm is relative to the drm objectis so I think this offset should be 0. Also, when I import vaapi frame to vulkan I got broken frame, and setting plane_data->offset to 0 makes command works.
