Re: [Discuss-gnuradio] stream_mux tag propagation

There is no special processing for stream tags in stream_mux. It simply takes 
the input streams and copies them input-wise into the output buffer. Stream 
tags are propagated according to their initial offset at the input. And there 
you get behaviour you described.

Did you have a look at tagged_stream_mux ? Maybe it will serve your needs? It 
sounds not unreasonable to have a switch to change tag propagation in 
stream_mux to your desired behaviour. Or is it a major breakage to the tag 
propagation policy?
