<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> </head> <body bgcolor="#ffffff" text="#000000">    Hi all,     I have a few questions related to the flutsmux/flutsdemux elements.    Firstable, which is the standard way to do streaming with the output of the "flutsmux" element? I mean, you get the output flow from "flutsmux", and do you directly encapsulate it into UDP packages for being sent through the network? Or it is normally used TCP packages, or any other kind of encapsulation before being sent?    Where can I find some more information/documentation about flutsmux/flutsdemux?    In "flutsdemux" I have seen that you have a property named "program-number". But, how do you mux several "programs" using "flutsmux"? Is there some pipeline example muxing several channels in a sender and then demuxing them in a receiver?     One specific question about a pipeline multiplexing streams. Next pipeline encodes 2 video and 2 audio streams into one .ts file (it works fine). But, how do I play either one stream or the other? gst-launch-0.10 \    filesrc location=video0.mp4 ! qtdemux ! h264parse ! queue ! mux. \    filesrc location=audio0.mp3 ! mp3parse ! queue ! mux. \    filesrc location=video1.mp4 ! qtdemux ! h264parse ! queue ! mux. \    filesrc location=inputs/audio1.mp3 ! mp3parse ! queue ! mux. \    flutsmux name=mux ! filesink location=test_2prog.ts I guess that is should be something like this, but I can play only video0 with audio0. gst-launch-0.10 filesrc location=test_2prog.ts ! flutsdemux program-number=1 name=demux demux. ! queue ! ffdec_h264 ! xvimagesink demux. ! queue ! mad ! alsasink demux. (changing "program-number" I always get: ERROR: from element /GstPipeline:pipeline0/GstFluTSDemux:demux: Could not determine type of stream)    THANK YOU VERY MUCH.    All the best.    LD. </body> </html>
