[BUG] Pat table lost PMT-pid

Hi, I have problem with getstream. After long time of working, getstream sending stream with all needed pids, but pat-table sends without pmt pid. Here is example of UDP-stream dump with PNR=1 and PMT=4110 Broken stream: http://magnus.wnet.ua/dump_notworking.ts After restarting of getstream: http://magnus.wnet.ua/dump_working.ts Here is VLC log of broken PAT: [00000427] ts demux debug: PATCallBack called [00000427] ts demux debug: new PAT ts_id=0 version=0 current_next=1 [00000427] ts demux debug: * number=1 pid=0 Here is VLC log of good PAT: [00000427] ts demux debug: PATCallBack called [00000427] ts demux debug: new PAT ts_id=0 version=0 current_next=1 [00000427] ts demux debug: * number=1 pid=4110

I misunderstood, as they listed the channels but not frequencies. Regards, Chris

2 multiplexes on the same frequency?
by Chris Hills 30 Sep '09

30 Sep '09

Hi I am using getstream for home use, and it is great! On 1st November a new multiplex will be transmitted in Denmark. According to the list at http://www.digi-tv.dk/Indhold_og_tilbud/frekvenser.asp it will use the same frequency as the first, but a different channel (29 vs 57 on Nibe-Tolne). How should getstream be configured to pick up either multiplex? My current configuration is as follows:- adapter 0 { dvb-t { frequency 538000000; bandwidth 8; transmission-mode auto; guard-interval auto; hierarchy none; modulation auto; }; [..] }; Regards, Chris Hills P.S. There is a stream report from dk-mux-1 at http://www.chaz6.com/files/dk-mux-1.html made with TSReader. A longer configuration is available from http://www.chaz6.com/files/config-dvbt-dk-9220.conf

Downscaling questions
by Ron van Herk 18 Sep '09

Hi, Is there a way to downscale the bitrate for individual http output channels (from dvb-S source) ? Or even downscale all the outgoing http stream bitrates? Best regards, Ron

update on CI/CAM support status
by Jakub Paweł Głazik 16 Sep '09

16 Sep '09

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

Question on compiling
by Ron van Herk 09 Sep '09

09 Sep '09

Hi, I just set up a new server, to tune in to DVB-S signals and stream them out internally. However, I get an error when compiling getstream. 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. How can I pick the right one with getstream? Thankls and best regards, Ron
