Re: [vdr] VDR 1.7.16 - emergency exit on recording HD shows

(Sorry for not responding using my mailer's Reply function, I didn't realize I couldn't do that in the digest mailing list mode.) After enabling the debugging options in remux.c as was suggested, all I got was a load of forward slashes in console output until it terminated. I failed to find any other useful debugging output. ////////////////////////////////////////////////grabbing event /////////////////////////////////////////////////[more slashes] frame duration = 3600 FPS = 25.00 FPPU = -2 /////////////////////////////////////////////////[more slashes] frame duration = 3600 FPS = 25.00 FPPU = -2 /////////////////////////////////////////////////[more slashes] # (terminated) The one-line patch provided here didn't help, I dare say it even can't, because the TV programs I have problems with are in H.264 and not in MPEG-2, in the switch branch of which the altered line is located. So if this is a problem related to I frames, I suppose we should tinker with the following line: independentFrame = Data[i + 1] == 0x10; Regards, -- Luboš Doležel

projects.vdr-developer.org - Domain down!
by Tobi 14 Nov '10

14 Nov '10

Hi! You might have noticed already, that projects.vdr-developer.org is not reachable right now. The whole vdr-developer.org domain seems to be gone. Let's hope it hasn't expired and some stupid domain grabber gets his hands on it. I've already contacted Siegmar at vdrportal.de (he's the domain holder). Meanwhile you can access projects.vdr-developer.org temporary under this address: http://community.xeatre.tv/ Sorry for the inconvenience! I hope this gets solved soon. Tobias

RfC: add encryption and compression to VDR
by Christian Tramnitz 13 Nov '10

13 Nov '10

Right now when the needs of a vdr extension goes beyond core SVDRP capabilities a different approach is being used by the each extensions. Prominent examples are: - vdradmin (using native SVDRP and suffering from its performance, optional use of direct file access to epg data) - live-plugin (integrating into vdr as plugin) - vdr iphone remote (using native SVDRP and due the bad performance and encryption capabilities an optional web-based interface) (and I'm sure there are more) While this is not bad per se there is obviously room for improvement. So my idea was to introduce a new standardized interface to VDR (either as plugin or native SVDRP commands) to plugins/extensions offering: - encryption (to be able to use it remotely in a more secure fashion) - compression (to overcome performance limitations especially when large amount of epg data have to be transferred) - and optionally authentication for obvious reasons Now I would like to start a few discussions related to this topic, the ones that come to my mind mind first are: - Should this be implemented as plugin or in core vdr as svdrp extension? - Would Klaus accept patches if this will be native SVDRP? - Are developers/maintainers of current or feature plugins/extensions interested in such a solution? - What technical implementation would make most sense? - Who would be willing to contribute to such a project? For the first step I was thinking about adding a "STARTTLS" command to core vdr (as patch) handling encryption and maybe also tranparent compression. This taks should be fairly easy as we could borrow ideas or even code from existing projects using STARTTLS (like mail servers). Authentication however would require a major redesign as far as I can tell. German version of this discussion can be found here: http://www.vdrportal.de/board/thread.php?threadid=101357 Thanks for your feedback, Christian

cSdtFIlter and LinkChannels
by Luca Olivetti 12 Nov '10

12 Nov '10

Hello, I'm trying to understand cSdtFilter in order to write a channel scanner. I see that when it finds a SI::NVODReferenceDescriptorTag it will add it to the previously found channel with channel->SetLinkChannels, but it only does if it is in the current section (channel is a local variable) while the sdt could span several sections. From the specifications here http://neuron2.net/library/mpeg2/iso13818-1.pdf and here http://www.dvb.org/technology/standards/a005r5.tm1324r13.tr101211.v1.10.1.p… I don't understand if this mechanism is correct, shouldn't the "time_shifted_services" link to the "NVOD_reference"? Besides, I don't see that the relation between a channels and its linkchannels is preserved in channels.conf (though I don't really care). I also see that cSdtFilter starts processing with the first section, and that shouldn't really be necessary as long as one processes all sections. Bye -- Luca

EPGSearch doesn't avoid repeats anymore?
by Teemu Suikki 11 Nov '10

11 Nov '10

Hi, I recently updated my VDR from 1.4.5 to 1.7.15, and also updated all plugins to their latest version. EPGSearch is epgsearch-0.9.25.beta17. Everything works, but epgsearch doesn't avoid repeats anymore! Here's an example from the file epgsearchdone.data: ---------------- R 1266873900 1800 0 C T-8438-8193-65 T Frasier D Kevyt-Frasier. KACL haastaa kilpailevan KPXY-aseman painonpudotuskisaan, ja vastapuolen tiimiss<E4> on Frasierin lukioaikainen koulukiusaaja. Niles ja Martin puolestaan hoivaavat ikkunaan t<F6>rm<E4>nnytt<E4> lintua. Amerikkalainen komediasarja. 11. @ <epgsearch><channel>4 - Nelonen</channel><searchtimer>Frasier</searchtimer><start>1266873600</start><stop>1266876300</stop><s-id>0</s-id><eventid>436</eventid></epgsearch> r ----- some time later ---- R 1289337600 1800 0 C T-8438-8193-65 T Frasier D Kevyt-Frasier.

Recordings Numbering
by Dominic Evans 11 Nov '10

11 Nov '10

Hi all, I was wondering about the recording numbers associated with recordings in the LSTR output. There doesn't seem to be any obvious pattern, is the numbering just random? It'd be preferable if recordings kept a unique number, that didn't change when every time a recording gets deleted, or a new recording is started. Cheers, Dom

UK users - multiple BBC One/Two/News in channels list
by Alasdair Campbell 09 Nov '10

09 Nov '10

Hi, Been a while since I've used VDR. Have it setup after scanning using the scan program, however something is strange. There are multiple versions of some channels, such as BBC One/Two/News, Channel 4 etc. Some of these either have video and no EPG, have video and EPG, or have EPG and no video... Obviously what I'm looking for is the video & the EPG - this works for BBC One, but when I tune to the BBC Two which has the EPG visible, I receive no signal found message. If any UK users have a cluestick on how to fix this, please let me know. It seems like VDR is updating the channels.conf but not merging the information, because a fresh scan using dvbutils does not show multiple versions for the same channel. Any help appreciated..

xine-lib and vaapi support
by Theunis Potgieter 08 Nov '10

08 Nov '10

I'm considering to upgrade my current p3 system to a hdmi/optical SPDIF and enough expansion slots to fill in dvb-s devices. I found plenty of motherboards with combinations of 2x or 3x pci and 3x pci-express. I can simply convert those pci-e to pci with an adapter so that is not a problem. The unkown factor for me is, should I consider a motherboard where the Core i3 (System on Chip) has got a built in hdmi interface? Or would I be better off with nvidia's vdpau, of consider to go ati/amd and what power usage are we looking at? Should I then rely on vaapi support again? The end result should be a machine that is good for vdr as a frontend and a backend, that is fast enough to be able to do transcoding on the fly for those mobile devices that don't accept mpeg2 natively. (I have been doing some transcoding using vlc + mediatomb on a core2 duo 1.8GHz). I'm trying to get rid of the core2 duo and the p3 (currently hosting the dvb-s cards) I don't see intel atom machines with at least 5+ expansion slots. You suggestions are most welcome. Thanks, Theunis

FF-Card and Receivers
by Rainer Blickle 07 Nov '10

Hi, i have a question about a vdr with a ff card. When watching tv with a ff card (=> not in transfer mode): Is there a receiver attached to the primary device ? I cannot test it by myself because i dont have a ff card. Regards, Rainer
