I've never really had that much success with HD channels on Freeview, although it seemed more stable with live TV rather than HD recordings. For me (I think! I tend not to bother trying most of the time!), I get both video and audio but after a while the video will freeze but the audio carries on. If I play back an HD recording, this will probably happen after a couple of minutes or so. Due to this, I didn't really both trying again until recently! I gave it another go when the olympics was on and BBC 1 HD played live fairly happily for hours on end. Every now and then the video would freeze but this could be fixed by switching to another channel and back (audio carries on quite happily otherwise!). The time between video freezes seems to be random so could be caused by an error in the stream that cannot be corrected, or something like that?! Every now and then, I update xineliboutput + libxine + ffmpeg to the latest cvs / hg / git source (and I can never remember which is which version control system!). I'm currently on all of those from near the end of July. I keep hoping it will suddenly "just work" but it hasn't really changed much in this respect that I can see. Also with vdr-1.7.29. For SD recordings it is much more stable although skipping multiple times in quick succession usually locks it up and requires vdr-sxfe to be restarted! It's a bit of a pain but I've (nearly?!) learned to live with that! Laz

Filesystem hierachy standard patch needs review.
by Christopher Reimer 07 Sep '12

07 Sep '12

Hi Mailinglist, could someone please review the attached patch? It's originally posted by Maniac in this thread --> http://www.vdr-portal.de/board60-linux/board14-betriebssystem/p1054966-vdr-… The documentation and some Makefile changes are my work. The main code changes are Maniac's work. I hope the code as well as the documentation is ok, so that the patch can be added in the next VDR Version. Thanks, Christopher Reimer

I used to have loads of problems with xine and AAC LATM encoded audio on my VDR rig, and mplayer tells me that your BBC recordings uses exactly that format: ... Playing 2012-09-07.02.07.54-0.rec/00001.ts. libavformat version 54.1.100 (internal) TS file format detected. VIDEO H264(pid=101) AUDIO AAC LATM(pid=102) SUB DVB(pid=105) PROGRAM N. 132 AFAICT support for LATM audio was only added in xinelib-1.1.19 and later: http://old.nabble.com/-PATCH--Add-AAC-LATM-support-from-FFmpeg-0.7%2B-td323… The LATM channels finally started working here when I upgraded to VDR+xineliboutput from the yavdr unstable packages. My install is a bit dated but I suppose it works with more recent versions than these, too: ii libavcodec53 4:0.7.6-0ubuntu0.11.10. Libav codec library ii libxine2 1.2.1.hg20120511.1541-0 the xine video/media player library, binary files ii vdr 1.7.22-2yavdr1~oneiric Video Disk Recorder for DVB cards ii vdr-plugin-xineliboutpu 1.0.7+cvs20120511.1602- VDR plugin for Xine based sofdevice frontends ii xine-ui 0.99.7~hg20120217-0yavd the xine video player, user interface Additionally I just tested that your recording plays with audio when played directly in xine on my LMDE (Debian Testing based) laptop with the following packages: ii libavcodec53 5:0.10-0.1 Library to encode decode multimedia streams - runtime files. ii libxine2 1:1.2.1-0.1 Xine media player library, meta-package (development branch). ii xine-ui 0.99.7~hg20120125-1 the xine video player, user interface So perhaps you need a more recent xine/libav combo. Cheers, Jonas

VDR File splitting validation
by Rares Pop 05 Sep '12

05 Sep '12

Dear all, We are using vdr (1.7.21) to record from a DVB-T2 stream. File split quota is at 200MB. The broadcast stream comes with audio packets (data) roughly 2 seconds after then the video packets. They are in perfect time stamp sync (video-audio). It is just the data packets that are late in the data stream). Now, when VDR does the file split (after the quota has been met and a video I-Frame is about to start) the audio packets that would be in sync with the latest video frames before the split are actually being contained in the next split file. This creates me big extra workload, I want to be able to process the split files individually, but I cannot since they don't have audio-video integrity. What would it take to make vdr splitting smarter in this case, that is to only split the files after all the significant audio packets have been received as well? Thanks for your attention, Rares -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

DVB cards and multichannel decoding
by Bernard Jaulin 02 Sep '12

02 Sep '12

Hi all, I want to renew my VDR box with a new PCI express DVB-S2 card. I just want to know if a multichannel decoding card is necessary for the multiple recordings ? A very small number of DVB cards have this feature... Regards, Bernard. --- *And thank you Mr Schmidinger and the community ! VDR is an amazing software with Infinity possibilities. It's really a pearl of free software ! *
