How do you stream the entire MPEG-TS with dvbstream?
Hi everyone,
I've just installed a new DViCO FusionHDTV dual digital 4 (which appears to the PC as two USB "Zarlink ZL10353 DVB-T" devices.)
I'm trying to set up dvbstream to send the whole transport stream across the network to another PC, but I can't get this to work. If I do something like this:
dvbstream -f 226500 -gi 16 -bw 7 512 650
Then it works fine, I get video and audio on the other PC and about 500kB/sec network use, but if I do this:
dvbstream -f 226500 -gi 16 -bw 7 8192
Then the network use goes up to 1.7MB/sec but the picture and sound arrive corrupted, as if I have extremely bad reception.
Using an old version of dvbstream with a Hauppauge Nova-T this works fine, except in that case I have 3MB/sec of network traffic with the same channel. It's almost as if the latest version of dvbstream doesn't correctly capture the whole MPEG-TS stream from the card.
Has anyone else gotten this to work?
Thanks,
Adam.

with the same drivers and a different version of dvbstream? In any case you should always try a fresh cvs checkout of dvbstream. A simple test you should run is this:
dvbstream -f 226500 -gi 16 -bw 7 -o 8192 > dump.ts
and try to play the dump.ts from another terminal. If you see corruptions then report back, please.P.S. 1.7 and 3 MB/s are really low bandwidth usage that shouldn't cause any trouble

OH, well this was with my distribution's most recent version, which I assumed would be only a month or two behind CVS. Unfortunately I've just realised that according to the banner it's version 0.5, whereas the "old" version I was running (with a last modified date of 2004) is version 0.6!
I was going to mention a couple of other issues I found while I was running your above command, but given that the version is so out of date I think I'll go file a bug report with my distro instead :-)
Thanks for your response!
Cheers,
Adam.

Well I've upgraded to today's CVS, but the problem remains. I've also tried the new version on my old server but it works there, so obviously there's some issue with my system configuration:
Working server: Slackware 9.1, kernel 2.6.11.6 (2005-06-19) Broken server: Gentoo 2007.0, kernel 2.6.24.2 (2008-02-23)
Both servers have Realtek 8169 gigabit ethernet cards, using the r8169 driver. Both MTUs are 1500, both are connected via the same switch to my desktop PC.
According to gkrellmd running on each server and on my desktop PC, broadcasting PID 8192 on the broken server only transmits/receives 1.7MB/sec, whereas it transmits/receives 3MB/sec on the working server.
Is there any local network config that needs to be set up before dvbstream will work?
Thanks,
Adam.
