update on CI/CAM support status

Hey all, Few months ago I posted some info on CI tests, and Romolo send me revoked CI patches. I tested then on TechnoTrend C-1500 DVB-S card and it didn't work, both original and Romolo's. Now I have DVB-S2 card TT-3200 CI on 2.6.30 kernel. In brief: 1. Getstream works with CI but only with some CAM's. SMIF Conax CAM: - with TVnaKarte smartcard (polish prepaid sat tv) works OK - with Filmbox channel smartcard DOESN'T work Technisat Conax CAM: - requires changes in DVR_BUFFER_SIZE in dmxdev.c kernel sources (buffer overlow), anyway - same situation as SMIF Conax CAM Viaaccess CAM with Eurosport2 works OK Nagravision CAM - DOESN'T work. 2. EVERYTHING listed above works ok using VLC. 3. Running VLC before getstream (to initialise CAM) doesn't help. 4. Romolo's revoked patches do not change the situation, but the debug output differs. 5. getstream even has problems with locking on a transponder when using not supported CAMs Attached 4 files: win - 3 adapters with TVnaKarte (Conax CAM) and Viaaccess, working ok win_revoked - same but with Romolo's patches (look and the PMT messages and errors. don't know why so much, anyway streaming worked without any problems) fail - Filmbox adapters (Conax CAM), do not work fail_revoked - same with Romolo's patched I'll do some more research next week to check what exactly fails with some CAMs and maybe compare the code with VLC. Any hints from you would be helpful! -- .: Jakub Paweł Głazik, .: email & jabber: zytek<at>nuxi.pl

I am no expoert in this, so if anybody can help it would be more then welcome: root@sat-2-p2p-server:/home/getstream# make gcc -O0 -g -Wall -I. -I/usr/include/glib-2.0/ -I/usr/lib/glib-2.0/include/ -c -o getstream.o getstream.c getstream.c:21:19: error: event.h: No such file or directory In file included from output.h:5, from sap.h:5, from getstream.h:15, from getstream.c:23: libhttp.h:82: error: field ‘ev’ has incomplete type In file included from sap.h:5, from getstream.h:15, from getstream.c:23: output.h:116: error: field ‘rtcpevent’ has incomplete type output.h:128: error: field ‘event’ has incomplete type In file included from getstream.h:15, from getstream.c:23: sap.h:41: error: field ‘event’ has incomplete type In file included from getstream.c:23: getstream.h:233: error: field ‘patevent’ has incomplete type getstream.h:256: error: field ‘timer’ has incomplete type getstream.h:257: error: field ‘event’ has incomplete type getstream.h:296: error: field ‘dvrevent’ has incomplete type getstream.h:298: error: field ‘stucktimer’ has incomplete type getstream.h:318: error: field ‘event’ has incomplete type getstream.h:323: error: field ‘dmxevent’ has incomplete type getstream.c: In function ‘init_guard_evtimer’: getstream.c:57: error: storage size of ‘gevent’ isn’t known getstream.c:63: warning: implicit declaration of function ‘evtimer_set’ getstream.c:64: warning: implicit declaration of function ‘evtimer_add’ getstream.c:57: warning: unused variable ‘gevent’ getstream.c: In function ‘terminate_init’: getstream.c:88: error: storage size of ‘event’ isn’t known getstream.c:88: warning: unused variable ‘event’ getstream.c: In function ‘main’: getstream.c:136: warning: implicit declaration of function ‘event_init’ getstream.c:177: warning: implicit declaration of function ‘event_dispatch’ make: *** [getstream.o] Error 1 root@sat-2-p2p-server:/home/getstream# Also, another question: My DVB-S is connected to a multiswitch with 4 satellite positions.

[Bug] Memleak in libhttp.c
by Hervé Rousseau 23 Aug '09

23 Aug '09

Hi there, While packaging getstream for Debian, someone from the Debian Devel list (George Danchev) reported a possible memleak in the code, he also included a patch. Here is what he said : [...] There is also a very innocent memory leak you might want to fix: --- libhttp.c.orig 2009-08-23 16:36:05.000000000 +0200 +++ libhttp.c 2009-08-23 16:39:43.000000000 +0200 @@ -556,11 +556,15 @@ hs->sin.sin_addr.s_addr=INADDR_ANY; if (bind(hs->fd, (struct sockaddr *) &hs->sin, - sizeof(struct sockaddr_in))) + sizeof(struct sockaddr_in))) { + free(hs); return NULL; + } - if (listen(hs->fd, 3)) + if (listen(hs->fd, 3)) { + free(hs); return NULL; + } flags=fcntl(hs->fd, F_GETFL); fcntl(hs->fd, F_GETFL, flags | O_NONBLOCK); Cheers, -- Herve Rousseau

Getstream seems to be working, but not the HTTP part
by Bonny Gijzen 09 Aug '09

09 Aug '09

Hi, First of all thanks for this nice application. I am trying to get it working with dvb-c but I seem to have some problem. I am using recent git tree version. I am using a config file like this: http { port 80; }; adapter 0 { budget-mode 0; packet-buffer 50; stat-interval 2; stuck-interval 2; dvb-c { frequency 826000000; symbol-rate 6875000; modulation 64; }; #Nederland 1 HD:826000000:INVERSION_AUTO:6875000:FEC_NONE:QAM_64:101:102:201 stream { name "Nederland 1"; input { pid 101; pid 102; pid 201; }; output-http { url /ned1; }; output-pipe { filename "/tmp/ned1"; }; }; }; Here is the output from the console: root@DVB-SERVER:~/getstream# ./getstream -c ./configs/ziggo.conf -d 2009-08-09 10:21:21.831 fe: Adapter 0 Setting up frontend tuner 2009-08-09 10:21:22.376 dmx: Setting filter for pid 101 pestype 20 2009-08-09 10:21:22.377 dmx: Setting filter for pid 102 pestype 20 2009-08-09 10:21:22.377 dmx: Setting filter for pid 201 pestype 20 2009-08-09 10:21:22.385 dvr: lockup of DVB card detected - trying to reanimate via bouncing filter 2009-08-09 10:21:22.404 dvr: lockup of DVB card detected - trying to reanimate via bouncing filter 2009-08-09 10:21:22.412 dvr: lockup of DVB card detected - trying to reanimate via bouncing filter 2009-08-09 10:21:22.420 dvr: lockup of DVB card detected - trying to reanimate via bouncing filter 2009-08-09 10:21:22.428 dvr: lockup of DVB card detected - trying to reanimate via bouncing filter 2009-08-09 10:21:22.443 fe: Adapter 0 Status: 0x1f (HAS_SIGNAL HAS_CARRIER HAS_VITERBI HAS_SYNC HAS_LOCK) 2009-08-09 10:21:24.377 dvr: inputstats: 2 pids 8256 pkt/s 1552222 byte/s 2009-08-09 10:21:26.377 dvr: inputstats: 2 pids 8353 pkt/s 1570458 byte/s When I can the /tmp/ned1 file I get a bunch of data, so this seems fine. When connecting with HTTP (I tried to use mplayer (w32), VLC, NMT) and there doesn't seem to be any data sent out ... Could this be a bug in current git tree? Is there anything else I can check? I hope I configured my dvb-c card ok, because there aren't any config examples ... Thanks, Bonny

HTTP output
by Y.Bosco 30 Jul '09

30 Jul '09

Hi! There are lines at getstream.conf which read something like: http { port [someport]; }; ....................................... output-http { url /[some name]; }; If you try to open http://[netaddress]:[someport]/[some name] with VLC then you could see a movie (if it exists :) ). I tried to include a link to http://[netaddress]:[someport]/[some name] into a web page, but the browser could only save the file (?!) under that link. I tried to change browser options but nothing changed. Is it possible to include links into web pages or not? Other videos like http://www.rbctv.ru/live/open.shtml are displayed properly. -- Mr. Yourij Bosco Bosco Electronics http://boel.ru

Your switches must support IGMP. And you'll need an igmp querier, normally the router handles this part. It it's an linux router, try xorp.

Multicast routing
by Nicola Caldera 30 Jul '09

30 Jul '09

Hello to all, is a bit of time getstream use and i am very satisfied, the program is stable and light, congratulations! Using getstream with a Skystar 2 HD "and" Airstar, ubuntu 9.04. The problem is that I always flodded the network from various channels. What multicast router do you use? You may help me? Thank you!

DVB-T config

Hi, I just wanted to let you know, that the dvb-t sample config file shipped with getstream does not work. I attached one that works nicely with my dvb-t adapter and current getstream git release.
