Yes, they all demux in userspace themselves. If you search the archives, I've pointed out this same problem. One thing you do lose with the kernel demuxing system is the relationship between the different streams. For instance, a PMT change takes effect for all packets that follow it, but with the demuxed streams, you don't know where that is. Of course if you want to work with existing systems, you have to demux in userspace since no one will have this new feature yet. And if you're doing that anyway, it's more work to add additional support for demuxed TS streams to your software. That probably why no one has bothered to add this feature. _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
