lcdproc and Logitech G15 (Illegal instruction) ?
by Gregoire Favre 23 Nov '07

23 Nov '07

Hello, is there something "special" to do in order to get lcdproc working on my G15 lcd keyboard ? Or maybe another LCD plugin ? I got a really suspicious Illegal instruction when compiling with gcc-4.3alpha of today so I tried with gcc-4.2.2 with same result. With gcc-4.2.2 I used : -g -march=k8 -pipe And with 4.3alpha : -g -O3 -march=core2 -DPIC -pipe -Wall If I start vdr with -Plcdproc I get on the LCD : "Welcome to V D R Video Disk Recorder Version : 1.5.12" Then : " Mute `black bar" " Some epg info" And then vdr quit with : "Illegal instruction" OK, then some gdb : gdb ./vdr GNU gdb 6.7.1 Copyright (C) 2007 Free Software Foundation, Inc.

Q::LinuxTV::USB-DVB-S -- what is supported?
by Andrey Vlassov 22 Nov '07

22 Nov '07

Hi, My friend is looking for USB DVB-S device with support HDTV. A quick search on seach engines didn't give much information. Could you share your expirience with USB DVB-S devices and give some recommendations what to buy? At this time he interested to buy it and make it work in Windows and little latter when he will get more confortable with Linux -- make it work in Linux. So far we found next devices: http://cgi.ebay.com/Twinhan-DTV-VisionPlus-Starbox-NIB-Sealed_W0QQitemZ2001… http://cgi.ebay.com/USB-2-0-DVB-S-Satellite-HDTV-TV-receiver-w-Remote-SAT_W… http://cgi.ebay.com/GeniaTech-Satellite-DVB-S-FTA-USB-Receiver-HDTV_W0QQite… Could somebody who has any experience with this devices share what advantages and disadvantages this devices have? NOTE: LinuxTVWiki does not have any information for USB devices http://www.linuxtv.org/wiki/index.php/DVB_USB http://www.mjmwired.net/kernel/Documentation/dvb/README.dvb-usb Could you refer us to documentation with a list of supported USB DVB-S devices? What would be best place to buy USB DVB-S device? Thank you, Andy

VDR & EPG documenation
by sundararaj reel 22 Nov '07

22 Nov '07

Hi, I am novice in VDR programming. I tried writing a plugin for getting EPG data from the Internet and using it. Now a prototype is up and running. To debug, extend and maintain the plugin I could use some more information. I wish I could get my hands on some documentation on the VDR classes (what they do...) and EPG ( for eg. how/when to set eventID, TableID ). I have with me doxygen generated documentation. But I still do not have something on par with cEvent::FixEpgBugs() kind of comments. Any help would be welcomed. Thanks in advance, Sundararaj

[Announce] vdr-scheduler-0.1.0
by Christian Wieninger 22 Nov '07

22 Nov '07

Hi, here's a new plugin especially for VDRs not running 24/7. It allows you to execute tasks in the context of VDR and trigger wakeups for this. Features: - optional wakeup of VDR to execute a job (no dummy timers needed anymore) - prevent a shutdown while a job is still executed - optional announcements of job start/finish via OSD - start external jobs via SVDRP in the context of VDR - display current and previous job output Requirements: - vdr >= 1.5.1 or - vdr-1.4.5 with the backport of the new shutdown handler (http://www.udo-richter.de/vdr/patches.html#shutdown) Project homepage and screenshots: http://winni.vdr-developer.org/scheduler Download: http://winni.vdr-developer.org/scheduler/downloads/vdr-scheduler-0.1.0.tgz Have fun!

Bug ? dvbsubtitle.c lign 105
by Gregoire Favre 21 Nov '07

21 Nov '07

Hello, lign 105 of dvbsubtitle.c is : bool Decode8BppCodeString(const uchar *Data, int &Index, int&y, int y); shouldn't that be : bool Decode8BppCodeString(const uchar *Data, int &Index, int&x, int y); Or better all 3 advanced declarations ligns : bool Decode2BppCodeString(const uchar *, int &, int&, int); bool Decode4BppCodeString(const uchar *, int &, int&, int); bool Decode8BppCodeString(const uchar *, int &, int&, int); At least with gcc 4.3alpha of today I can't compil vdr-1.5.1x with this. -- Grégoire FAVRE http://gregoire.favre.googlepages.com http://www.gnupg.org http://picasaweb.google.com/Gregoire.Favre

Multiple diseqc.conf's when using multiple dvb devices??
by VDR User 20 Nov '07

20 Nov '07

Greets. If you have more then one dvb device and each is plugged into a diseqc switch, how would you define a diseqc.conf for each of them? I've checked VDR's documentation and saw no reference to this unless I've somehow missed the info. If VDR doesn't currently support different diseqc.conf's per each dvb adapter, I guess this could be a formal request to add support for this. Maybe just doing something like this: # Format: device satellite slof polarization lof command where device is used for this purpose? Not sure the best way to identify the devices since they can be pci, pci-e, usb, etc. Any thoughts? Thanks fellas!

HD setup
by Gregoire Favre 19 Nov '07

19 Nov '07

Hello, I know 720p, 1080p/i resolution are getting common which is fine. >From the next feature thread I see there is some interest in H.264 channels :-) I don't like the hardware decoder solution : Intel core duo 2 are really cheap now and don't use that much power... I built my VDR PC (in fact my only PC...) with such a solution (and a fanless nvidia gfx card) and I find it perfectly suited for HD. The most important part from my point of view was the case : http://techgage.com/article/antec_p182_performance_mid-tower/ So that I don't have noise from the PC... I think almost any PC with core duo 2 CPU are enough for perfect H.264 decoding... I don't really like closed hardware solution neither... -- Grégoire FAVRE http://gregoire.favre.googlepages.com http://www.gnupg.org http://picasaweb.google.com/Gregoire.Favre

> Besides, I don't think > that many users are still using some ancient pc with a slow cpu > like Klaus has. I've been using a IBM Netstation, 266mhz, 128 mb ram with a FF dvb-s and a aver 771 dvb-t. It worked FLAWLESSY ! I could record 2 streams and play a third one, the OSD was slow but recording were ok. (At the time I used ~1 Ghz AMD and Intel chip and chipsets that were not able to handle the load !!!!) Now it has hardware and software problems... I will solve as soon as I have time... Aver 771 doesn't work anymore, don't know why, it doesn't lock any signal. Also in a Windows PC. I just bought an USB stick, I'm looking for a PCI-USB2 adapter. I upgraded the ram to 256 and then upgraded from suse 9 to 10.3.... that is a bloated S.o. that takes forever to do anything.... Francesco

vdr-1.5.11 & subtitling problems
by Rolf Ahrenberg 18 Nov '07

18 Nov '07

Hi, I'm having heavy artifacts with the new vdr-1.5.11 in finnish DVB channels. The picture freezes now very often compared to previous VDR version (I reported about the same rare problem in vdr-1.5.10) and it seems that the problem is the new SUBTITLE_PACKS size. I reverted it back to 2048 and haven't noticed the problem after that. During the freeze VDR's transfer buffer gets full and VDR is clearing transfer buffer to avoid overflows. This happens only on channels with DVB subtitling. I'm using 4MB FF card as a primary device, if that makes any difference. BR, -- rofa
