Re: [Discuss-gnuradio] stream_mux tag propagation

Hi Merlin,

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?

Best Regards,
