[ANNOUNCE] naludump 0.0.1
by Udo Richter 13 Feb '11

13 Feb '11

Hi list, This is the test version 0.0.1 of my h.264 nalu fill data removal tool. The tool deletes NALU fill data from h.264 streams embedded into TS files, like VDR recordings. The overall file structure isn't modified, only complete TS packets of NALU fill data are removed. On HD TV channels that use fixed video bandwidth, this can save 40-60% file size without loosing any data. Version 0.0.1 is a standalone tool to process single files, and is mainly for compatibility tests and verification. Please use it on recordings, then check whether these recordings seem un-modified, and if you have, use stream verification tools like ts-doctor for verification. Later versions will also integrate into VDR as a patch, and will filter out these fillers while recording. For backgrounds, and for the Nalustripper tool of MartenR, see http://www.vdr-portal.de/board/thread.php?threadid=98948 For vdrportal topic, see: http://www.vdr-portal.de/board/thread.php?threadid=102634 Source code available here: http://www.udo-richter.de/vdr/naludump.html (de) http://www.udo-richter.de/vdr/naludump.en.html (en) For code readers: Most files are stripped-down versions of VDR code. New code is in naludump.c (basic file processing) and remux.c (class cNaluDumper and some helper functions). Cheers, Udo

Detecting recording errors
by Tobias Grimm 10 Feb '11

10 Feb '11

Hi! Is there a patch/plugin/tool/whatever which would make VDR somehow tag recordings where there were stream-error when recording? It shouldn't be too hard to scan a *.ts-File for discontinuity errors, but I would like to make VDR detect this while recording and somehow set a flag, so I can see if a recording might have errors. BR, Tobias

It appears to just not work at all :S Both are working. You need a compositing manager like xcompmgr or compiz for the first possibility, or the option "--opengl-all" (not sure about correct typing" for the second possibility. Gerald

Problem with VDR h264 ffw/rew (using VDR-1.7.16)?
by VDR User 28 Jan '11

28 Jan '11

When fast forwarding or rewind h264 VDR recordings, the still frames update very slowly. Often times I've seeked several minutes in a recording before the still frame updates and this is much farther then I intended. This doesn't happen with mpeg2 recordings at all. The still frames update very often with those making seeking to the right spot no no problem. Is this a flaw in how VDR seeks h264 or would it be an issue in xine-lib or vdr-xine? This seems worthwhile to address since the still frames are the only reference a user has to tell how far he's seeked in a recording. Can someone please shed light on how to fix this? Thanks.

[PATCH] GOTOX patch for vdr-1.7.16
by Ales Jurik 28 Jan '11

28 Jan '11

Hi, after some time I've improved the gotox patch for vdr - it is now correctly resolving condition for sending diseqc command in cDvbTuner::SetFrontend(void) even if diseqc command doesn't change also with cascaded diseqc switches. So the diseqc is now sent immediately after channel switch and not after frontend tuning is timeouted. It was tested with diseqc.conf entries like this (cascaded: motor <-> uncommitted switch <-> committed switch): S1.0W 11700 V 9750 t V G [E0 10 39 F1] v W30 [E0 10 38 FC] W30 v t S1.0W 99999 V 10600 t V G [E0 10 39 F1] v W30 [E0 10 38 FD] W30 v T S1.0W 11700 H 9750 t V G [E0 10 39 F1] V W30 [E0 10 38 FE] W30 V t S1.0W 99999 H 10600 t V G [E0 10 39 F1] V W30 [E0 10 38 FF] W30 V T S9.0E 11700 V 9750 t V G [E0 10 39 F1] v W30 [E0 10 38 FC] W30 v t S9.0E 99999 V 10600 t V G [E0 10 39 F1] v W30 [E0 10 38 FD] W30 v T S9.0E 11700 H 9750 t V G [E0 10 39 F1] V W30 [E0 10 38 FE] W30 V t S9.0E 99999 H 10600 t V G [E0 10 39 F1] V W30 [E0 10 38 FF] W30 V T BR, Ales

Replacing aging VDR for DVB-S2
by Adrian C. 28 Jan '11

28 Jan '11

Hello, I'd like to replace my VDR with Duron 1200, Skystar2 and GeForce4. I'm not particulary interested in HDTV but I'd like to prepare the new VDR for the future, even though I'm on a budget. I'd buy Skystar2-HD with a GeForce that supports VDPAU. Would you be so kind to tell me if the SS2-HD works OK? Also with VDPAU, but more importantly in the absence of it would any of these CPU be up to the task of processing: Athlon2 X3 450 3.2GHz and Pentium E6500 or E6700 3.0GHz. Thank you very much. -- Adrian C. (anrxc) | anrxc..sysphere.org | PGP ID: D20A0618 PGP FP: 02A5 628A D8EE 2A93 996E 929F D5CB 31B7 D20A 0618

Remote receiver options...
by Laz 25 Jan '11

25 Jan '11

I've been following various threads over the past year or so exploring various options for having a server-client vdr setup and it got me thinking. I'm currently using a home-brew LIRC receiver attached to a serial port which works perfectly. The ION-based boards look very nice as a vdr front end (using xinelibout or some yet-to-be-written plugin!) because they can do hardware HD decoding. However, I suspect a lot of these lack a serial port so my simple LIRC receiver would be no good. What are others doing in this sort of situation? USB-based receiver (there are a couple described at lirc.org), or do most of the ION boards still have a serial header (must admit, not looked into this properly yet!)? Several DVB devices do contain receivers but that pretty much defeats the object of having a server containing DVB devices and a client just for viewing. It all looks nice in principle but any lack of a remote is a deal breaker! Cheers, Laz
