AFAIK, we don't have hwaccel for audio codecs. That sentence makes zero sense.

And again, you can't expect users to select decoders manually. If vvdec is the 
default, hwaccel won't work. If vvdec is not the default, then it's dead code.

So most people use libavcodec through higher-level frameworks or applications, 
not the CLI tool, and that is especially true for playback. If that's the 
super-niche use-case for vvdec, then I agree with Kieran that it's just bloat.

To handle multiple implementations of decoding for a given codec, and not 
force them as installation and load-time dependencies.
