VDR Issues with DVB-T Services in Israel
by Barak Nahari 24 Jul '11

24 Jul '11

Hi. I'm trying to get vdr working with DVB-T Services in Israel. I think that something maybe off with the transmission because I can watch the dvb-t stream with VLC, MuMuDVB but not with VDR and TVHEADEND. (In windows platform there isn't any issue, working with MediaPortal, MC7) I may add that I've really basic skills with linux and very limited experience with vdr. My goal is to set VDR as a TV server and XBMC machines as clients. I've followed this guide http://forum.xbmc.org/showthread.php?t=62696 and installed on ubuntu 11.04. My scan template # Initial scan config for Israel # T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy T 538000000 8MHz 2/3 NONE QAM16 8k 1/32 AUTO T 514000000 8MHz 2/3 NONE QAM16 8k 1/32 AUTO Successfully found and config the channels, installed vnsiserver. When trying to watch the channels with xbmc, xbmc connecting and disconnecting to vdr constantly (while i can see the channels listing on xbmc). I had no idea where to find the vdr log file, and didn't knew how to watch vdr stream without xbmc, so i've installed vdr-fbfe plugin run it and got allot of errors, you can see them in the attached file vdr-fbfe.txt. I had no idea where the problem origin, so i've followed this guide http://forum.xbmc.org/showthread.php?t=45314 to manual compile everything i could, that didn't help. I'm using a usb dvb-t dongle based on afatech af9015 chip running a virtualbox ubuntu machine. I've also tried a usb dvb-t dongle based on ite9135 chip (had to manual compile drivers). More info Using vlc to save the ts stream C:\Program Files\VideoLAN\VLC\vlc.exe dvbt://frequency=538000000 --demux=dump :demuxdump-file="D:\test.ts" you can get it from here http://www.2shared.com/file/9QZtoJrZ/test.html Scan information in scanlog.txt file. Stream info in streaminfo.txt file. Information on this issue in TVHEADEND https://www.lonelycoder.com/redmine/issues/251. I would be happy to get vdr working. Thanks in advance, Barak.

vdr-1.7.19 recording issue
by Mike Booth 21 Jul '11

21 Jul '11

I've got round the problem of noty being able to play recordings made with vdr-1.7.19 by removing recorder.c recorder.h recording.c recording.h and remux.c remux.h and replacing them with the same files from vdr-1.7.18. Not very elegant but seems to work with new recordings and in the absebce of anything else............................ Mike

DAB+, VDR and Linux
by Luboš Doležel 18 Jul '11

18 Jul '11

Hello, I'd like to experiment with DAB+ as there are now some broadcasts in my country. Are there any DAB+ receivers known to work under Linux? Does VDR (or other tools) support it? There is little information that can be found on this topic with Google... Thanks, -- Luboš Doležel

Diseqc problems with VDR1.7.19
by Hawes, Mark 18 Jul '11

18 Jul '11

Hi, Since upgrading to VDR 1.7.19 I have experienced problems with Diseqc. My diseqc configuration uses command strings which contain 3 code sets: a diseqc switch command, a diseqc go to command, and a repeat goto command. Since upgrading to VDR 1.7.19 it appears that the only code set sent is the last one, but it's sent three times. To demonstrate this I have put some trace in cDvbTuner::SetFrontend within dvbdevice.c which traces the complete diseqc string, the diseqc action, and for diseqc codes - the actual diseqc code sent. It produces the following output: Diseqc command list found = t v [E0 10 38 F4] W500 [E0 31 6B 04] W250 [E0 31 6B 04] W15 T Diseqc action = 1 Diseqc action = 3 Diseqc action = 7 Sending Diseqc command: E0 31 6B 04 < Wrong, should be E0 10 38 F4 > Diseqc action = 7 Sending Diseqc command: E0 31 6B 04 < Wrong, should be E0 31 6B 04 > Diseqc action = 7 Sending Diseqc command: E0 31 6B 04 Diseqc action = 2 The same trace in vdr 1.7.18 shows the correct codes being sent in the correct sequence. I note that some work was done in this area for 1.7.19 but my C++ skills are a little weak to diagnose the problem any further. Can anybody throw some more light on what's going on? Thanks, Mark.

HDHomerun and streamdev
by Rob Davis 15 Jul '11

15 Jul '11

I have just added an HDHomerun to my setup. This is a network tuner, which plugs into VDR with the hdhomerun plugin. VDR picks it up as another ATSC tuner and the same channels.conf works with it as with my ATSC tuners. However, I noticed streamdev doesn't work with it, to either another remote VDR server or VLC. If I turn off the plugin and use the ATSC cards it works again. Not much in the way of useful log info (Ie, nothing..) Rob

Ring buffer overflows with streamdev and remux script

[Patch] MAXCAIDS size increase
by LACARRIERE Jerome 06 Jul '11

06 Jul '11

Hi, On the channel MTV Live HD (S19.2) we reach the limitation of MAXCAIDS. This channel currently provides 9 conditional access ids. (MAXCAIDS is define to 8). To ensure that all users can access(decrypt) this channel, it's necessary to increase this size. it's the aim of the patch in attach file. MAXCAIDS increase to 12. channel details: MTV Live HD;MTV Networks Europe:11778:VC34M2O0S0:S19.2E:27500:2000=27:2001=@4;2002=eng@106 :0:D00,100,500,1810,1811,1863,1817,1818:28600:1:1068:0 Thanks.

strcmp() segfaults if one (and only one) of the parameters is NULL ?
by sundararaj reel 05 Jul '11

05 Jul '11

Hi, strcmp() returns 0 if both are parameters NULL, but segfaults if one of the parameters is NULL. Is this a known behaviour ? man page says nothing about NULL parameters. I ask because, vdr checks for NULL parameter(s) to strcmp() sometimes. Check for one or both parameters: epg.c:692: if (shortText && strcmp(title, shortText) == 0) { epg.c:742: if (shortText && description && strcmp(shortText, description) == 0) { No check for null parameter: channels.c:227: bool nn = strcmp(name, Name) != 0; channels.c:228: bool ns = strcmp(shortName, ShortName) != 0; -- Thanks, Sundararaj $ /lib/libc.so.6 GNU C Library (Ubuntu EGLIBC 2.11.1-0ubuntu7.7) stable release version 2.11.1, by Roland McGrath et al. ...
