March 2009 - Getstream

getstream + CI/CAM first tests
by Jakub Głazik 15 Apr '09

15 Apr '09

Hello everybody, I'm glad to inform about successful tests of latest CI/CAM patches - but with one issue: I have to first run VLC to run and decode interesting channel, kill it and THEN run getstream. If I run getstream without first run of VLC - I have no output and no error messages. If I do rmmod/modprobe dvb_ttpci I have to run VLC again before running getstream. My setup: - Ubuntu Intrepid @NFS, stock kernel 2.6.27-13-generic - TT Premium-S C-1500 (?) with CI slot. - getstream from repo, latest CI/CAM patch with g_threads_init fixes. CAM tested: - aston crypt - nagravision 3 More to come. It works fine for 6 hours now: ps aux: root 5719 3.3 0.3 28572 1976 pts/0 Sl+ 17:44 12:22 ./getstream/getstream -c config.travel top: 5719 root 20 0 28572 1976 1056 R 3.9 0.4 12:23.23 getstream Tomorrow I'll send some debug output, I'm just dropping this mail so you could tell me some hints how to test this weird behaviour. Some initialization problems? I wish to test it with my TT-S3200+CI DVB-S2 card, hope that CI patch is compatible with multiproto? I have problems with C-1500 that it crashes every few hours and there's need to rmmod/modprobe before the card can work again. -- Jakub Glazik zytek at nuxi.pl

adapter lockup
by Jakub Paweł Głazik 17 Mar '09

17 Mar '09

I'm using TechnoTrend 1500/1600 cards (Premium-S) and they like to lockup randomly. For example I'm seeing situation when one of two configured adapters hangs and I get output only from one adapter. dvr.c has a hack for Flexcop cards and on debug output I have seen that bouncing filter works for TT card reanimation but every now and then it does not. I would like to detect such situation, getstream could die and I would do some scripting for bringing everything up again (module reload or even reboot). Should it be implemented in internal watchdog or in dvr_stuck_timer, maybe some retry-counter with SIGABR when reanimation does not work for a card after N tries? -- .: Jakub Paweł Głazik, .: email & jabber: zytek<at>nuxi.pl

100% cpu usage when closing controling terminal
by Jakub Paweł Głazik 06 Mar '09

06 Mar '09

When I run getstream in the background and close the terminal (ssh session) cpu usage goes to 100%. root@odb:~# getstream -c config & root@odb:~# logout Effect - 100% cpu usage and after a while getstream dies. Running it through nohup helps: root@odb:~# nohup getstream -c config > /dev/null & After this I can logout and everything works ok. Any ideas? I could work on adding a true 'daemon mode' to getstream next week. -- .: Jakub Paweł Głazik, .: email & jabber: zytek<at>nuxi.pl

What do you think about this patch http://tipok.org.ua/downloads/iptv/DVB/getstream/patches/filter-ps-es.diff in config it's look like stream { name "FG"; input { pid 3336; }; output-http { filter { es; }; url /fg; }; }; maybe include it to repo? -- С уважением, Mihail Lavkin mailto:lmikd@nm.ru

DVB Streaming Question
by David Devereaux-Weber 03 Mar '09

03 Mar '09

I'm receiving a number of encrypted satellite channels with two Motorola DSR4410MD (multi-decrypter) satellite receivers. As the name implies, they can decrypt multiple encrypted channels (up to 64!). And the output can be ASI or Ethernet. They are output as a MPTS. Can getstream accept an MPTS over Ethernet and break them up into individual multicasts, also over Ethernet? Dave -- David Devereaux-Weber, P.E.
