VDR with 50Hz clock output
by martinez 25 Aug '10

25 Aug '10

Looking at the circuit diagram for the vga2scart cable. at http://vga2scart.gw90.de/cable/vga2scart/ What pins need to be mapped on the scart to include also sound (for a complete vga+ stereo out > SCART cable) Message: 1 Date: Sat, 21 Aug 2010 15:54:03 +0300 From: Pasi K?rkk?inen <pasik(a)iki.fi> Subject: Re: [vdr] Advice on new motherboard, xineliboutput, vdpau, hdmi video & audio, etc. To: vdr(a)linuxtv.org Message-ID: <20100821125403.GW2804(a)reaktio.net> Content-Type: text/plain; charset=iso-8859-1 On Fri, Aug 20, 2010 at 01:37:10AM +0300, Niko Mikkil? wrote: Thu, 2010-08-19 at 20:54 +0400, Goga777 wrote: Computer hardware usually cannot provide 50.000Hz, 59.940Hz or 23.976Hz outputs to your TV/Monitor. This will cause some judder on display output as MPEG/AVC input-stream is not synchronized to output framerate. do you mean that all nvidia vdpau cards with existing drivers from Nvidia can't provide exact 50.000Hz, 59.940Hz or 23.976Hz ?? There is no graphics card, BD/DVD player or other standalone device that outputs those rates exactly. I don't know how much they deviate, but I'd guess it's usually something like 0.01 % (50.005 Hz instead of 50 Hz), as Jori said. However, the rate doesn't need to match exactly because the display device is synchronized to the video signal. The rate could be 50.1 Hz or maybe even 51 Hz and the display wouldn't mind. 50 fps video files would play slightly faster, but there would be no need to drop video frames because of that. Things are more problematic when receiving live broadcast. Then the display and the video source (graphics card and software) needs to be synchronized to the broadcast to avoid dropping or duplicating frames. Set-top digital television boxes and FF DVB cards do that, but most graphics cards/drivers can't because they aren't designed to follow an external time source. Audio playback synchronation is another issue, and somewhat difficult to handle properly on a PC where the audio chip's clock is almost always separate from the graphics card's clock. By default, many media players time everything according to the audio clock, and therefore they need to drop/duplicate video frames every now and then. The other alternative is to drop/duplicate audio frames or resample the audio completely. I assume you guys are aware of projects like: http://frc.easy-vdr.de/ It was originally started to get perfectly synced RGB output from a VGA card (to PAL TV), just like from FF DVB card. I haven't really used that myself, but afaik they've been working on making that exact synchronization (variable framerate) possible with new HD/VGA/DVI outputs aswell. -- Pasi

Automatic shutdown / restart of VDR
by Lari Tuononen 24 Aug '10

24 Aug '10

Hi! I've been trying to play with different settings around nvram-wakeup and vdr. My idea of the working setup would be: * VDR will shut down the computer ONLY when it is told so with the power-key (so VDR will continue recording if there is a timer active or coming in next few hours) * VDR will wake up if timer is to record and computer shut down * VDR will not shutdown automatically I've managed to get the waking-up working properly, and also so that VDR will shutdown at night after the last timer has stopped, but if there is a timer in the morning and it wakes computer up, VDR also shuts down the computer, which is something I do not want. Settings in setup.conf: MinEventTimeout = 120 MinUserInactivity = 0 So the question is: Which settings should I have to get the functionality I like? Best Regards, Lari Tuononen

projects.vdr-developer.org update to Redmine 1.0.0
by Tobi 23 Aug '10

23 Aug '10

Hi! On August 21 / 22 I will update projects.vdr-developer.org to a new Redmine version, so please be prepared for some service downtime. With the update Redmine will show Git-branches and tags in its built-in repository browser plus some other nice features. I try to make this transition as smooth as possible, but I might need to take down the whole service for some hours. Only the Redmine webinterface will be affected and you can still use the Git repositories! bye, Tobias

Re: [vdr] speeding up vdr+xine on an old Pentium4
by martinez＠embl.de 22 Aug '10

You are absolutely right, the P4 has indeed 2.4GHz (and 512MB of RAM) Which makes it the more surprising that on SD channels I am getting cpu utilization in the region of 80% to 95% It should be a lot less? This is the lspci output for the graphics card: 00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 01) 00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) Date: Sat, 21 Aug 2010 23:34:15 +0100 From: Tony Houghton <h(a)realh.co.uk> Subject: Re: [vdr] speeding up vdr+xine on an old Pentium4 To: vdr(a)linuxtv.org Message-ID: <20100821233415.5c6c5a7f(a)realh.co.uk> Content-Type: text/plain; charset=ISO-8859-1 On Sat, 21 Aug 2010 22:41:32 +0200 <martinez(a)embl.de> wrote: I?ve taken an old PC (Intel graphics card on board, P4@553Mhz, 512Megs of RAM) and installed mms, vdr and lirc basically. Do you mean P3 or have you mistyped the clock speed? The slowest P4 was about 1400MHz, I thought. Surely one wouldn't be underclocked by such a huge factor. -- TH * http://www.realh.co.uk

vdr-1.7.15 dvb-t channel mismatch
by Stefan Lucke 22 Aug '10

22 Aug '10

Hi, reststarting my vdr activities I went into trouble with dvb-t channels.conf for Berlin. Just took the channels from: http://www.vdr-wiki.de/wiki/index.php/Channels.conf_DVBT-De-Berlin-Brandenb… There is the following entry for ARTE: arte;ARD:191500:I999B7C23D12M16T8G8Y0:T:27500:201:202=deu,203=fra:204:0:2:8468:0:0 I was able to tune and watch tv on this channel, but there was no EPG available. VDR created the following new entry in channels.conf: arte;ARD:191500000:B7C23D12G8M16T8Y0:T:0:0:0:0:0:2:8468:257:0 Tuning to this VDR generated channel shows now the EPG information, but no video and no sound :-(. -- Stefan Lucke

speeding up vdr+xine on an old Pentium4
by martinez＠embl.de 21 Aug '10

21 Aug '10

Hi, I´ve taken an old PC (Intel graphics card on board, P4@553Mhz, 512Megs of RAM) and installed mms, vdr and lirc basically. Everthing works fine but I see cpu utilization in the region of 90% (this is with SD, I have no delusions about HD channels on this hardware) At the moment it is connected to a monitor, so I have a feeling it goes for the maximum resolution. Eventually it will be connected to an old 28 inches TV (CRT not LCD) with an adaptor VGA to RCA Any tips on how I could speed things up? Xine settings? Xorg settings? vdr settings? xv or opengl?

nvidia-vdr closed driver or open source?
by martinez 20 Aug '10

20 Aug '10

Hi, I have an onboard nvidia 8200 graphics card, using vdr-1.7.15 connecting with xine and using xv , not vdpau At the moment out of habit I am using the nvidia proprietary driver, but should I use the open source instead? Which one is likely to yield better performance in my setup? Cheers, Art

Dish Network and Diseqc switches.
by Rob Davis 19 Aug '10

19 Aug '10

I had a nice European sat system until moving to the US. Since coming here I've cludged VDR to work with cable using PVR cards and an HD-PVR. However, I bought a Dish Network satellite "Superdish" at an auction for about $2.50 and wondered if I can get it working with my DVB-S cards. It appears to have three LNB's, a dual one and then a side one. Each LNB seems to have two plugs coming off it. Can I connect all three to a Eurospec Diseqc switch I brought with me or does it need it's own switch from Dish Networks?

Re: [vdr] xineliboutput - pausing playback takes time
by JJussi 18 Aug '10

18 Aug '10

Hi! I found "fix" to this problem.. After removing .xine directory (from home of 'vdr'; user what runs vdr-sxfe) pausing works as it should be.. When vdr-sxfe starts, it created again that .xine directory.. But it (directory) stays empty. After creating config_xineliboutput to that directory (file is empty; touch config_xineliboutput) problem returns, but not every time when you try to pause playback... Strange!

Re: [vdr] frequent xine crashes with vdr
by martinez 17 Aug '10

17 Aug '10

Hi Reinhard, Unfortunately I can not reproduce it anymore, because in the meantimeI installed a newer version of xine-lib and the problem disappeared. What I notice is that using vdpau, on 28e BBC HD for example drops many frames (unwatchable, although cpu load remains low), whereas using xv the same channels plays perfectly (although ITV1 HD even using xv drops some frames) So for me it is xv for now as vdpau does not seem quite mature Regards, Art
