25 years of VDR
by Klaus Schmidinger 06 Jul '25

06 Jul '25

25 years ago today, on February 19, 2000, I released the very first version of the VDR. I never thought that this project would keep me busy for a quarter of a century. I would like to use this special anniversary to thank the many users who have contributed to the further development of VDR with suggestions, patches, bug fixes and plugins. At its peak, there were more than two thousand VDR users around the world (who registered with the VDR User Counter), of which today there are still a good 800 active. With the availability of media libraries and streaming, interest in a DVB recorder has naturally waned. However, there are also advantages to being able to record films and series under your own control without being exposed to the risk that they will disappear from the online offering at some point. On the page https://www.tvdr.de/cgi/vdr-counter?action=summary I have shown the history of the number of users over the years (generated from the counter's log file). In the first years of VDR, the number of users increased rapidly, peaking at over 2200. In March 2015, the counter started sending emails to those who had not accessed their entry for more than a year, marking them as "outdated" if they did not respond with a confirmation of their entry. This caused the number of active users to drop abruptly by almost 800, and in the following years it continued to decrease. Apparently many of the initial 2200 users only used VDR for a short time. In October 2024, this mechanism was revised so that those who have been notified once since 2015 will be notified again on a regular basis and have the option to either confirm or delete their entry. Here too, the number of active users fell by several hundred and settled at just over 800 in January 2025. Perhaps the "dark figure" is higher, because not everyone reads the VDR-Portal or the VDR mailing list. In any case, I still enjoy the project, and TV without VDR is unthinkable anyway ;-). I wish all VDR users continued enjoyment with it! Klaus

Thanks

About 10 years ago I built an OTA recording system using a SiliconDust ethernet receiver connected to a BeagleBone (linux) computer recording to a SD card and then uploading to a NAS file server in the wee hours. I hired an Elance programmer in Spain to write the code to interface with the SiliconDust "calls". I recorded Craig Ferguson and football programs mostly. Later I moved away from Denver and no longer needed the system. But all these years later I still was amazed and intimadated by the VDR system and liked to read about the progress and challenges. All of you and especially Klaus deserve much thanks for all your efforts and dedication. I still use KODI on an Android box once in a while, but now your efforts have prompted me to build my own VDR in tribute to 25 years of your efforts. Thanks again for all the enjoyment in reading your exploits. Bruce

[ANNOUNCE] VDR version 2.7.4 released
by Klaus Schmidinger 26 Feb '25

26 Feb '25

VDR version 2.7.4 is now available at the official VDR GIT archive git://git.tvdr.de You can also get the latest stable version with git clone --branch stable/latest git://git.tvdr.de/vdr.git or as a tar archive with http://git.tvdr.de/?p=vdr.git;a=snapshot;h=stable/latest;sf=tbz2 The changes since version 2.7.3: - Removed all DEPRECATED_* code. - Fixed error checking in case the fps value can't be determined by the frame parser. - Updated the Italian OSD texts (thanks to Diego Pierotto). - The VDR homepage is now accessible via HTTPS. - Updated the Finnish OSD texts (thanks to Rolf Ahrenberg). - Fixed some typos in the translation files (thanks to Stefan Hofmann). - Added some missing locking. - TS packets with errors are now skipped when parsing for frames. - Fixed handling the fps value if it can't be determined from the video data. - Fixed accessing a timer's event schedule in case the event has been removed from the schedule. - Fixed a possible deadlock when canceling an editing process. - Checking for VPS control is now limited to local timers. - Added 1 to Utf8BufSize() for worst case (thanks to Stefan Hofmann). - Fixed handling margins for timers that are not VPS controlled and not spawned (thanks to Markus Ehrnsperger). - Added a header to the backtrace (thanks to Stefan Hofmann). - Added parameter checks to strn0cpy() (thanks to Stefan Hofmann). Same for Utf8Strn0Cpy(). - The info files of recordings are now only re-read if they have been modified (thanks to Stefan Hofmann). - The new virtual function cStatus::OsdItem2() can be used to get the information whether a menu item is selectable (thanks to Markus Ehrnsperger). Plugins that implemented cStatus::OsdItem() will still work as before, because the default implementation of cStatus::OsdItem2() calls cStatus::OsdItem(). APIVERSNUM is now 30006. - Fixed setting the file name of the info file after renaming a recording (reported by Stefan Hofmann). - Fixed an improper call of cStatus::OsdCurrentItem() before cStatus::OsdItem2() (reported by Markus Ehrnsperger). - Fixed an unnecessary redisplay of the menu when pressing a hotkey. - Fixed unnecessary calls to DisplayCurrent() for editable menu items (thanks to Markus Ehrnsperger). - The new virtual function cStatus::OsdCurrentItem2() can be used to get the index of the current menu item (thanks to Markus Ehrnsperger). Plugins that implemented cStatus::OsdCurrentItem() will still work as before, because the default implementation of cStatus::OsdCurrentItem2() calls cStatus::OsdCurrentItem(). - Fixed unnecessary calls to cStatus::OsdCurrentItem2() when scrolling. - Added missing calls to cStatus::MsgOsdStatusMessage() and added the new virtual function cStatus::OsdStatusMessage2(), which can be used to get the type of the message (thanks to Markus Ehrnsperger). Plugins that implemented cStatus::OsdStatusMessage() will still work as before, because the default implementation of cStatus::OsdStatusMessage2() calls cStatus::OsdStatusMessage(). - Adjusted PLUGINS.html to the new API version numbering introduced in version 2.7.2. - The function cPlugin::MainThreadHook() has been deprecated and may be removed in future versions. Use proper locking instead. - Fixed unnecessary redisplays of menus. - Added '~' to the list of delimiters in cTextWrapper (thanks to Stefan Hofmann). - Fixed progress display when switching from "pause" to "slow back" (reported by Andreas Baierl). - Fixed spurious fast frames when switching from "slow back" to "slow forward". - Fixed cPtsIndex::FindFrameNumber() to handle the case where Pts points to an I-frame. - Added missing locks to SetMenuItem() functions. - Revised locking in cMenuSchedule and cMenuWhatsOn. - Plugins need to be rebuilt.

How to play MPEG PS files?
by Marko Mäkelä 09 Feb '25

09 Feb '25

I got some video files in MPEG PS format. These files would not play in VDR even if put them in directories named after timestamps and name them 00001.ts. The command vdr --genindex fails to create any index file. However, if I first convert them to MPEG TS format with ffmpeg -i file.mpg -c copy 00001.ts then VDR will recognize and play the files (but report at least one error per second). I was wondering if there is a way to play MPEG PS recordings in VDR, or a FUSE program that would make the recordings appear as something that VDR recognizes. If I understand correctly, the MPEG PES format that VDR originally used (the 001.vdr files) is kind of a subset of the PS format. If possible, I'd like to avoid any such conversion, at most add some index files for VDR playback. I found https://github.com/vdr-projects/vdr-plugin-dvd which should be able to deal with the video format (DVD uses MPEG PS), but I suppose it would only work with an actual DVD (if it is compatible with a current VDR version).
