I don't understand what you mean by that. What does not work?

Well you can't have it both ways:
- Either we redirect, and there is not going to be any metadata.
- Or we use a playlist, and we'll have the URL expiry problem (and major delay 
in parsing larger playlists).
That same conumdrum affects any other plugin, and redesigning the VLC input is 
a non-goal.

Maybe we can add a preparsing mode, a meta fetcher module or a meta reader 
module, though I don't really understand the functional difference between the 
later two. (Maybe it is so that reader is supposed to read from the input byte 
stream and fetcher from the internets. But that seems like an implementation 
detail.)

We are not going through the playlist demux in that case, so I don't exactly 
understand how you blame it on using the playlist demux.

And playing without metadata is surely no worse than failing to play and also 
to get any metadata, which is the current situation with VLC for most 
YoutubeDL-supported sites.
