VideoFrames backed by one NV12 texture are currently sent to the compositor as RGB VideoFrames. The compositor can sample out of those wihtout worrying about the underlying buffer format since they behave as normal RGB textures. We're planning to change the format of these VideoFrames to NV12.
In order to scanout from these buffers we need to know the buffer format. This patch makes VideoResourceUpdater produce an associated resource that has YUV_420_BIPLANAR buffer_format for NV12 VideoFrames backed only by one native texture.
