This seems like making it impossible for the Lua stream filters to 
return a different content than the original stream, in order to trigger 
the adaptive streaming demuxer. Could a demuxer actually forward the 
content to another demuxer ?

This is not just for Lua scripts. The ytdl module should also do the 
same rather than force one version of the stream regardless of 
network/screen/gpu capabilities.
