while having the default vtdec at secondary rank. This allows decodebin/playbin to prefer the hardware based decoders, and if that fails to initialize because hardware resources are busy to fall back to e.g. the libav based h264 decoder instead of the software based vtdec (which is slower), and only fall back to the software based vtdec if there is no higher ranked decoder available.
