Johan, - Try using an 800x600 resolution, I know that typically nVidia, ATI and S3 chipsets drive the TV (at least NTSC) with that setting. - You might want to try disabling "XvMC" (GPU assisted video decode) - I think with older nVidia drivers you had to use their AGPGart and not the one in the kernel, that might be something else to check. - Disable video de-interlacing in softdevice. You WANT an interlaced signal since most TVs are interlaced. Does TV-out work OK if you watch a DVD or play some other kind of video clip? Finally, there is also the "nvtv" program which might give you some additional settings to tweak your card with. Please report back if you get it working. Regards, C.

[ANNOUNCE] ExtRecMenu-Plugin 0.11
by Martin Prochnow 30 May '06

30 May '06

Hi folks, here a new release of my Extended-Recordings-Menu-plugin. - added czech translation; thanks to Vladimír Bárta - added missing dialog for video dvds - added more meaningful error messages - avoid empty names and names starting with . or .. while editing - free space display in title bar is now updated immediately - switched off editing of recordings and directories while a cut is in progress - switched off resume by 'Play' or 'Menu'->'Blue' for archive dvd recordings - changed back the behaviour if replay ends; plugin has to open to unmount archive dvds - removed setup option "While opening jump to last replayed recording"; its implemention interfers with the following one - after renaming a recording, the selection bar now stays at this renamed list entry - the parameters 'move' and 'rename' for the '-r'-option of VDR have now the following format: move/rename oldname newname - fixed hopefully all problems in connection with renaming and moving directories - plugins closes if there are no recordings - fixed Screenshots and download: http://martins-kabuff.de/extrecmenu_en.html Have fun with it! Greets, Martin

reelchannelscan-0.3.0 with complete empty channels.conf before
by Matthias Schwarzott 30 May '06

30 May '06

Hi! With this patch applied reelchannelscan will no longer crash if the channels.conf file was completely empty before scanning. Btw. why I am able to start vdr with a completely empty channels.conf, but not when the file is missing. I thinks this should be changed, vdr should create the file if necessary.

Zapping between channel with many audio tracks
by nouche 1er 30 May '06

30 May '06

Hi, Now, I try to write a plugin, in this plugin I want to switch channel and I use : > cChannel *Channel = Channels.GetByNumber(Number); > if (Channel) { > cDevice::PrimaryDevice()->SwitchChannel(Channel, true); > } It works perfectly with common channels, but when I have two channels with multiple audio tracks, like these: > MOSA 2:12324:vC34:S19.2E :27500:163:1921=fra,1922=fra,1923=fra,1924=fra,1925=fra,1926=fra,1927=fra,1928=fra,1929=fra,1930=fra,1931=fra,1932=fra,1933=fra,1934=fra,1935=fra,1936=fra,1937=fra,1938=fra,1939=fra,1940=fra:0:0:8604:1:1096:0 > MOSA 3:12324:vC34:S19.2E :27500:164:1941=fra,1942=fra,1943=fra,1944=fra,1945=fra,1946=fra,1947=fra,1948=fra,1949=fra,1950=fra,1951=fra,1952=fra,1953=fra,1954=fra,1955=fra,1956=fra,1957=fra,1958=fra,1959=fra,1960=fra:0:0:8605:1:1096:0 > MOSA 4:12324:vC34:S19.2E :27500:166:1961=fra,1962=fra,1963=fra,1964=fra,1965=fra,1966=fra,1967=fra,1968=fra,1969=fra,1970=fra,1971=fra,1972=fra,1973=fra,1974=fra,1975=fra,1976=fra,1977=fra,1978=fra,1979=fra,1981=fra:0:0:8614:1:1096:0 Vdr switch the channel, but it still black screen (no audio, no video). When I zap using the channel menu, I have the same result. MOSA 2 -> MOSA 3 = Black MOSA 2 -> An Other Channel -> MOSA 3 = OK MOSA 2 -> MOSA 3 -> MOSA 4 = MOSA 3 Black then MOSA 4 OK I would know if there is a solution to switch directly between these channels. Perhaps a solution like this: 1) Switch to MOSA 2 2) Switch to MOSA 3: 2 a) " "Unload" MOSA 2 audio tracks" 2 b) Switch channel to MOSA 3 Have you got any ideas ? What can I do ? Thanks BR, Nouche

Re: vdr-1.4.0-2, g++ 4.1.1 compiler warning

Hello Ville, I'm making this a ML posting to allow others to comment on this, too. Hope that's ok with you. Well, looking at <pthread.h> it does look like there actually should be a pointer to a 'struct sched_param'. But then again it says: The realtime scheduling policies SCHED_RR and SCHED_FIFO are available only to processes with superuser privileges. which VDR usually isn't. Since I assume that the line in question doesn't have any effect if a NULL pointer is given as 'param', maybe it's safe to drop it altogether? Klaus

Running Perl script from VDR via commands.conf ?
by karim 29 May '06

29 May '06

Hello, I am trying to run a Perl script from VDR menu, but it sticks VDR after one second : "timeout". I've added this line in VDR's commands.conf : MY_SCRIPT: /usr/local/bin/myscript.pl & How could I launch the Perl script in background mode ? Thanks.

vdr and ppc
by Luis Palacios 29 May '06

29 May '06

Hi, Has anybody running vdr in a PPC box?. The idea is to take advantage of a Mac Mini box with PowerPC and try to use it with VDR as a remote client, so I would need vdr, streamdev and softdevice at least. I´m having problems with Softdevice as there are some X86 dependencies on the utils.c file. Any tip or suggestion would be really appreciated. Thanks, Luis

Re: [vdr] [PATCH] find v4l device on kernel 2.6 (GRAB Problem)
by Travel Factory S.r.l. 29 May '06

29 May '06

I casually discovered that GRABbing is sometimes working sometimes not. I have a Nexus FF + an AverMedia DVB-T. No message in the log, just an empty grab image. I should investigate if the problem resides on which card tunes first.... Francesco

Maybe it is ok for stable to, but dont know ;-). I just found this old thread while cleaning up my inbox. Is this still a problem, or have things gotten better due to other changes (VDR or driver) in the meantime? Sorry for having lost sight of this one...

analogTV ffmpeg can't find video grab device
by Simon Baxter 28 May '06

28 May '06

I've been trying to get analogTV working with a PVR-150, but the ffmpeg fails. I ran the syntax myself: ffmpeg -f mpeg1video -s 352x288 -ad /dev/dsp:14 -ar 44.1 -vd /dev/video0 -ac 1 -b 2000 -ab 80 -y -re -title analogTV -author analogTV -copyright GPL -comment analogTV -aspect 4:3 -tvstd NTSC /tmp/.analogtv.avi and it fails as ffmpeg can't find the video grab device /dev/video0 but if I change it to: ... -i /dev/video0 ... the encoding starts ok, but I still don't see a picture. Any ideas??
