Scanning and channels.conf problems
by anthony kelly 15 Mar '07

15 Mar '07

Hi I am not sure if I should post this to vdr or to v4l/dvb as I'm not sure where the problem lies. One of our local TV stations changed their broadcast configuration as follows: "Guard Interval will change from 1/8 to 1/16 The FEC will change from 2/3 to 3/4" To get this channel working again, I tried to scan a new channels.conf. I changed the transponder file au-Darwin appropriately. Before this the scan did not see the 2 channels from this station at all, after the change it did. However, neither vdr or tzap is able to lock onto the config output. The errors are respectively: VDR: frontend 0 timed out while tuning to channel 17, tp 557 TZAP: ERROR: error while parsing inversion (syntax error) The dvbscan I used is from csv in 19/12/2005, all other channels work fine with the channels config output. I got the latest DVBAPPS and found that dvbscan no longer exists, but "scan" seems to replace it. However, scan produces a different output again, and vdr will not tune to any channel from the resulting output. I have a friend in Darwin who changed his au-Darwin transponder file in the same way and scanned and got workable outputs for him. But his channels.conf entry for this particular channel doesn't work for me either. In the past I have noticed that both he and I have different channels.conf formats but they have both worked find so I never worried about it. He and I were both on VDR 1.4.X also. Sorry if I am wandering here, I have tried so many things that I don't know exactly where the problem lies. In summary: -the latest scan utility generates output my vdr cannot read (1.4.1 or 1.5.1) -the older dvbscan utility generates output that works for all channels but one -my friend does the same thing and gets channel configs that work for him on all channels, but not for me. My config is: Debian 2.6.14.4 vdr 1.5.1 Compro DVB300-T tuner (SAA7134) v4l/dvb from csv (I think) from 14/6/2006 My latest scan output is: ABC HDTV;ABC:543625:I999B7C34D999M64T8G16Y0:T:27500:2314+2309:0;2315:2316:0:640:0:0:0 ABC TV Darwin;ABC:543625:I999B7C34D999M64T8G16Y0:T:27500:512+128:650=eng;660=eng:576:0:641:0:0:0 ABC2;ABC:543625:I999B7C34D999M64T8G16Y0:T:27500:2307+2306:2308=eng:2310:0:642:0:0:0 ABC TV;ABC:543625:I999B7C34D999M64T8G16Y0:T:27500:512+128:650=eng:576:0:643:0:0:0 ABC DiG Radio;ABC:543625:I999B7C34D999M64T8G16Y0:T:27500:0:2317=eng:0:0:646:0:0:0 ABC DiG Jazz;ABC:543625:I999B7C34D999M64T8G16Y0:T:27500:0:2318=eng:0:0:647:0:0:0 Nine Darwin SD;NINE NETWORK:550500:I999C34D34M64B7T8G8Y0:T:27500:512+128:650=eng;651=eng:578:0:1793:12921:0:0 Nine Darwin HD;NINE NETWORK:550500:I999B7C34D34M64T8G16Y0:T:27500:514+130:0;671:578:0:1794:12921:0:0 SBS HD;SBS:536625:I999B7C23D23M64T8G8Y0:T:27500:102:103=eng:41:0:864:12802:0:0 SBS DIGITAL 1;SBS:536625:I999B7C23D23M64T8G8Y0:T:27500:161:81=eng:41:0:865:12802:0:0 SBS DIGITAL 2;SBS:536625:I999B7C23D23M64T8G8Y0:T:27500:162:83:0:0:866:12802:0:0 SBS DIGITAL;SBS:536625:I999B7C23D23M64T8G8Y0:T:27500:161:81=eng:41:0:867:12802:0:0 SBS RADIO 1;SBS:536625:I999B7C23D23M64T8G8Y0:T:27500:0:201:0:0:878:12802:0:0 SBS RADIO 2;SBS:536625:I999B7C23D23M64T8G8Y0:T:27500:0:202:0:0:879:12802:0:0 SCTV Darwin;SCTV:557625000:I999C23D23M64B7T8G8Y0:T:27500:609:610=eng:611:0:2305:12954:0:0 SCTV HD - Darwin;Southern Cross Television:557625:I999B7C23D23M64T8G8Y0:T:27500:3311:0;3312:611:0:2337:12954:0:0 The last 2 entries (SCTV*) are the ones that do not work. They differ from the rest in the order of the parameters (i.e all the others are IxBx whereas the onex that donw's work have the B* much later). I have tried to manipulate these manually to match the others with no success. Also interestingly the guard interval is scanned as 8 instead of the 16 it should be. Any ideas are welcome. I am at a complete loss. I have very old card drivers, could this make a difference (I tried new ones but couldn't get them compiled). Thanks in Advance Anthony Kelly

TV Standards option for vdr-1.5.x
by Stone 15 Mar '07

15 Mar '07

Hi, In all the prevous versions of VDR, I have had to patch the FRAMESPERSECOND and change the rest of the hardcoded PAL values in VDR for my NTSC television. Is making this an option in VDR on the TODO list? Best Regards.

ATI + mesa driver + vdr-xine = buffer usage : 100% -> X freeze
by Sébastien Serra 14 Mar '07

14 Mar '07

Hi, my system : - ubuntu edgyup-to-date, - radeon 9700 using opensource radeon driver - vdr 1.4.3 (Eclipse pack from vdr.bluox.org) + vdr-xine 0.7.10 + xine-lib and xine-ui found at http://home.vrweb.de/~rnissl/ When DRI is loaded and 3D acceleration is ON my X server quickly freezes. My log (using ssh) tells me something like buffer usage: 0% (tid=19349) ERROR: 1 ring buffer overflow (177 bytes dropped) Mar 21 03:30:45 sid vdr: [19350] buffer usage: 70% (tid=19349) Mar 21 03:31:00 sid vdr: [19350] buffer usage: 80% (tid=19349) Mar 21 03:31:01 sid vdr: [19350] buffer usage: 90% (tid=19349) Mar 21 03:31:02 sid vdr: [19350] buffer usage: 100% (tid=19349) When i disable 3D acceleration (non dri) everything works fine but on HD channels (Astra, MPEG2) CPU load higher. Is there a way to prevent this sort of vdr buffer overflow ? I would like to keep my 3D acceleration enabled thx

very unlikely bug report / race condition in cRecordings vs. extrecmenu plugin
by Patrick Cernko 14 Mar '07

14 Mar '07

Hi List, I'm not sure at all if this is a bug / race condition or a miss-operation my the user (== me ;-) ). I just used the move-between-filesystems feature from the extrecmenu for the first time. Obviously, this ran for some time. While it was still running, I renamed another recording (in the target recordings folder). When the move was finished, the recording disappeared from the source location but it did not appear in the target location. A quick look into the logfile showed up that everything was successful, so I simple touched the .update file and after reopening the (ExtRecMenu)-Recordings-Menu the recording showed up correctly. Attached you can find the mentioned log section. My first idea was a missing recording registration in this new feature in the extrecmenu plugin, but this seems to be correct. Maybe it is some sort of thread synchronization problem in cRecordings as the moving is done in a seperate thread in extrecmenu. I can perfectly live with this issue but I thought it might be a good idea to let you known about it. Maybe someone sees the cause of the problem. @Klaus: Maybe you can integrate a "update" menu item anywhere, e.g. in Setup->Recording (similar to "scan" in Setup->EPG), when you have some free time? So long, -- Patrick Cernko | mailto:errror@errror.org | http://www.errror.org Eva: "Geht das bei den Floeten mit etwas mehr PATOS?" H.J.: "Is' dos der Schoofskaes'?"

how do you get a valid channels.conf?
by Bob Self 13 Mar '07

13 Mar '07

I have a nexus-s satellite card and am running Ubuntu edgy eft. The card works fine. I can zap to FTA channels using szap using an old incomplete channels.conf I had. I'm trying to create a new channels.conf for echostar 7 at 119w so that I can use vdr to change channels instead of szap. I trie running the scan that comes with dvbutils, dvbscan from Thoraz but they both create channels.conf files that don't work. They are incomplete or have the wrong frequencies. Eg, I've tried ./dvbscan -G -lDBS -o vdr -e 3 -s 1 -x 0 -p dvb-s/echostar-119w > channels.conf.119w For the NASA channel it shows the frequency as 12369 but it should be at 12370. So I manually changed it to 12370. I then ran vdr and changed to NASA but I get a blank screen. Does anyone know why that could happen? the line in /etc/vdr/channels.conf is NASA:12370:v:S119.0W:20000:4130:4131:0:0:213:4100:11:10000 the .conf file for szap shows nasa as: NASA:12370:v:1:20000:4130:4131:213 I'm not sure how I got this .conf file but it works for szap. Questions: 1. does scan or dvbscan work for N.A. satellites? 2. I've read about an nscan. Does that one work? 3. How do you get a valid channels.conf file for N.A. sats? With dvbscan I find that it can't tune to some transponders that are supposed to be on the satellite, or records the wrong frequency in channels.conf and gives incomplete results (maybe because it can't tune to a transponder). thanks, Bob

epia ex10000eg - platform for vdr?
by Marco Skambraks 13 Mar '07

13 Mar '07

hi, during my search for a good vdr plaform I found some epia boards with the cx700 chipset (mpeg2/4 acceleration) the epia drivers for xorg should support the mpeg acceleration is this true? and is it useable togther with softdevice? in the documentation epia says that a patched xine from sourceforge supports the acceleration features thanks marco -------------------------------------------------- AMMEC - Accessible Multimedia Entertainment Center http://www.ammec.de Email: Marco Skambraks <marco(a)ammec.de>

[ANNOUNCE] New plugin remotetimers-0.0.1
by Frank Schmirler 13 Mar '07

13 Mar '07

Hi, the successor of streamdev's former remote timers feature is finally there. You can get the new remotetimers plugin at http://vdr.schmirler.de. Features: - Add, edit and delete timers on the local (client) VDR and a remote (server) VDR - Move timers between client and server - Assign user IDs to timers. Filter the timer list by user ID. - Support for MainMenuHooks patch. Replace the VDR mainmenus "Schedule" and "Timer" by remotetimers' counterparts. In addition, the plugin comes with its own "Schedule" menu. Adding timers without EPG is not very convenient, is it? All menus are more or less copies of VDR's originals. That should help to keep up with changes in VDR. Credits to Klaus and everyone who contributed to those parts of the code I copied. Remotetimers requires the svdrpservice plugin. So make sure, both plugins are installed. Differences between the original VDR menus and their remotetimers counterparts: The edit timer menu has two additional options: Location determins if the timer is stored on the local or the remote machine. Use this setting to move the timer from client to server or vice versa. Note that you cannot move a running timer. You will have to stop it first. You can assign a user ID to each timer. Every user or client can use its own ID or maybe you want to distinguish timers by genre? Whatever you prefer. You can then filter the timer list by ID. The special ID "0" actually means "no ID". A corresponding timer will always be visible. In the plugin setup you can determine the default values for location and user ID. In the timer list you will see a letter in front of the channel number. "L" indicates a local timer, "R" a remote timer. Use the number keys to filter the list. Press "0" to see all timers. Any other digit will show only timer with a matching ID and timers with ID "0". The menu title shows the current filter setting. In the plugin setup you can configure the default filter. There's nothing special about the schedule menus, of course except for the fact that remote timer matches are marked with "T", too. Note that there's no user ID filter. You will always see all timer matches. Warning: This is the very first release of the plugin. Even though it works perfectly for me, it may not in your environment. Keep this in mind when testing and maybe doublecheck the timer list on the remote VDR. Enjoy, Frank

vdr-xine 0.7.10 buffering
by Jouni Karvo 13 Mar '07

13 Mar '07

hi, as the kernel finally supports standby or spin down or whatever mode for my SATA disks, I have set up an aggressive scheme trying to spin down disks whenever possible. The results: 2 degrees drop in case temperature and a significantly lower noise. And a playout "problem"... It takes about 5 secs to start stopped disks. It is not a problem when starting a recording, but when recordings span over several disks there will be an annoying pause when it is time to start reading from another disk. The live-TV buffering works like a charm, though. Is there a possibility to configure (for example) a 10s buffering for playback while keeping the live-TV buffering as it is now? yours, Jouni

NTSC vdr playing on PAL TV cropped
by Simon Baxter 12 Mar '07

12 Mar '07

I'm running vdr-pvrinput and vdr-xine. Until recently I was living in the US (NTSC land), but moved back to NZ (PAL land) recently. I'm also now playing at 16:9 Everything I watch or record here is at full screen, but all the recordings I made in the US are cropped with verticle black bands up either side. Can I 'stretch' the replaying image horizontally? Thanks Simon

6-channel audio from analog?
by Simon Baxter 12 Mar '07

12 Mar '07

Hi y'all. My media box has 6 channel output LF,RF,LR,RR,C,SW which I'm using with ALSA. Mplayer plays through all channels fine (settings in ~/.mplayer/config), but VDR sourced audio only plays in stereo from the LR,RF output. Given that there is no way to play 'real' surround sound from pvrinput sourced audio, what is the easiest way to 'copy' the audio to the other channels, so I at least get sound out all the speakers? Hmm, perhaps this is a setting in xine...? Thanks Simon
