Firewire output on cable box.
by Rob Davis 19 Feb '11

19 Feb '11

Hi Guys, I discovered yesterday that my cable box produces usable input on the firewire output. Following a mythtv tutorial I managed to get a reasonable ts stream dumped to a file. However, each channel appears to have it's own vpid and apid/dpid (often several) similar to ATSC content. I'm guessing the cable box it outputting the raw ts. To get the fire I followed this page: http://www.mythtv.org/wiki/FireWire And managed to get test-mpeg2 working. This file was playable (in really good quality) on xbmc. Is there a way I can get this into VDR? I tried iptv, but ffmpeg throws an error: [mpegts @ 0x80719c0] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 228701 >= 228701 av_interleaved_write_frame(): Operation not permitted Probably due to bugs in the ts stream.. I also tried test-mpeg2 -r 0 - | nc -u 127.0.0.1 4321 in a script but iptv believed the script had finished and tried to kill it? I can put a 1 min sample somewhere if it'll help?

The finnish translation file is nowadays in UTF-8 (as most of the Linux distributions), but gettext should handle the charset conversion automatically. Somehow this conversion seem to fail on your system. BR, -- rofa

startup problems
by Jouni Karvo 17 Feb '11

17 Feb '11

hi, after upgrading my kernel to 2.6.37 SMP PREEMPT x86_64 and switching to the in-kernel lirc devinput drivers, I have had vdr startup problems. At some boots; typically when the system wakes up from sleep, either by RTC or by power key from the remote, VDR watchdog-restarts every 1 minute for arond 10 times (this last time, it did it 14 times). Only after that it starts properly, xine starts and picture, sound and remote control start working. When rebooting, vdr might start immediately, without this restart hassle. Before; using the imon drivers, this problem did not occur. vdr-1.7.16, lircd from the git repo. I don't know where to start. Is this a vdr, lirc or a driver problem, or perhaps initscript order problem? Should I try the 2.6.38-rc5, or would that be just looking for trouble? yours, Jouni

[PATCH] do not flag all audio tracks as "clean effects" in remux.c
by Anssi Hannula 14 Feb '11

14 Feb '11

Hi! cPatPmtGenerator::MakeLanguageDescriptor in remux.c incorrectly flags all audio tracks as "clean effects", which means a track without any voice or language. The proper solution would be to preserve the audio_type of the original stream (which may indicate e.g. a visual-impaired audio track, as used for e.g. automated subtitles-to-speech audio tracks by YLE here in Finland). The attached patch is a simpler stop-gap measure that simply always sets the audio_type to the value of 0x00 which means a "normal" track, which is obviously better than marking the track as a special "clean effects" one. -- Anssi Hannula

[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

AvetTV a761

Hi. I have Aver Media AverTV a761 dvb-t tuner, on bt878 and SP887x. And 2 troubles with it. 1. It works well with kaffeine, but does not work with vdr. Kaffeine can scan and play dvb-t h.264 transponder in my area. With vdr I can scan channels only, with reelchannelscan or wirbelscan. When I try select dvb-t channel, I have message info: Channel not available!

vdr-plugin-live 'multischedule'

Just happened to notice the new MultiSchedule tab on live had shown up in my yaVDR-based VDR today. Looks great! Posting these links for people that haven't seen or heard about this new feature: http://www.vdr-portal.de/board/thread.php?threadid=102587 http://www.vdr-portal.de/board/attachment.php?attachmentid=27115 Seems there's been quite a bit of activity on the vdr-live git repo recently. Great to see. http://git.gekrumbel.de/?p=live.git

[ANNOUNCE] streamdev 0.5.1 / moved to projects.vdr-developer.org
by Frank Schmirler 11 Feb '11

11 Feb '11

Hi, a few month ago streamdev's CVS got lost when www.vdr-developer.org moved to a new server. In the meantime I moved the project to projects.vdr-developer.org. Unfortunately only the latest releases plus a few snapshots could be saved from the old CVS tree and imported into git. Streamdev's old address http://streamdev.vdr-developer.org now forwards to the new home http://projects.vdr-developer.org/projects/plg-streamdev. I just released the new version 0.5.1, mostly a bugfix release. Some of the fixes have also been applied to the 0.4 branch (for VDR 1.4.x). In case there's still interest in this old releases, please contact me and I'll publish a final 0.4.1. Changelog of 0.5.1: - updated copy of GetClippedNumProvidedSystems to the version used since VDR 1.7.15 (reported by carel@vdrportal) - fixed the code deciding if a device is in use for live TV or not. It did not work as expected for FF cards (reported by wtor@vdrportal) - increased client side timeout for TUNE command - more dsyslog messages to help troubleshouting channel switch issues - improved the channel switch code trying to move live TV to different card - make sure that a client doesn't interrupt replaying on server's FF card (reported by wtor@vdrportal) - switching away live TV failed even when "always suspended" (reported by Michal Novotny) - fixed regression: no receiver created for ES/PS/PES (reported by Gavin Hamill) - VTP no longer uses a static priority value for its server-side receivers. The server stores channel and priority requested with the PROV command and re-uses these values in a subsequent TUNE for the same channel. The new PRIO command is used to update the receiver's priority if necessary. - added parameter HEIGHT to externremux.sh - fixed syslog messages reporting local instead of remote IP and port - fixed regression of the GetDevice(...) change. Filter streaming to clients with a recent VDR version no longer worked. - log an error if externremux.sh is missing or not executable - since VDR 1.5.0 cDevice::GetDevice(...) is no longer a query only method. It detaches all receivers of the device it returns. So it is no longer suitable for testing the availability of a device. Added a copy of VDR's cDevice::GetDevice(...) without the detach receivers part as a workaround until a better solution is available - added dsyslog messages to help troubleshouting channel switch issues - VTP command SUSP didn't attach the player to the primary device - fixed incompatibilities with older make versions - replacing a connections receiver is now an atomic operation. Solves stuttering audio/video due to lost TS packets when adding/removing PIDs - disabled attribute warn_unused_result in libdvbmpeg - slightly increased thread priorities of cStreamdevWriter/Streamer (suggested by Rolf Ahrenberg) - fixed missing support for invisible channel groups (groups without name) in HTTP menu (reported by Timothy D. Lenz) - don't quote actual program call in externremux.sh, so you can run the program through e.g. nice or taskset just by extending the variable which holds the program name - in externremux.sh each mencoder audio and video codec has a dedicated variable for a default option string now. Still you can override each default option with an URL parameter - externremux.sh mencoder now uses scale parameter with negative height instead of -xy for scaling (suggested by vel_tins@vdrportal) - added FPS (frames per second) parameter to externremux.sh (suggested by vel_tins@vdrportal) - don't use std::map.at(). It's not available in older libstdc++ version (reported by Matthias Prill) - fixed extremux x264 using value of ABR for VBR (thanks to vel_tins@vdrportal) Have fun, Frank
