Buffer overflows recording HDTV with saa7146 and mantis DVB-C tuners
by schorpp 05 Nov '24

05 Nov '24

Hello, I've build a new VDR with h.264 xineliboutput plugin software decoding and got a problem now with buffer overruns and distorted recordings on all HD channels: ... Nov 5 05:32:03 vdr2 vdr: [32753] ERROR: 47231 ring buffer overflows (8879240 bytes dropped) Nov 5 05:32:09 vdr2 vdr: [32753] ERROR: 31042 ring buffer overflows (5835896 bytes dropped) Nov 5 05:32:15 vdr2 vdr: [32753] ERROR: 47325 ring buffer overflows (8897100 bytes dropped) Nov 5 05:32:21 vdr2 vdr: [32753] ERROR: 28306 ring buffer overflows (5321528 bytes dropped) Nov 5 05:32:27 vdr2 vdr: [32753] ERROR: 14033 ring buffer overflows (2638204 bytes dropped) ... This occurs with both saa7146 and mantis pci tuner cards. This has not occured with the old VDR system using Broadcomm's crystalhd decoder in libxine. LIVE TV works fine. I've tried stable and testing minidvblinux.de VDR live systems to crosscheck, but same issue occurs. If I increase the buffer for the saa7164 cards with module parameter it's getting worse and distorted picture and sound. Any Ideas? Increase VDR's buffer in source code? What is the correct driver module debug parameter to provide a useful debog log? Y tom

VDR User Counter now uses OpenStreetMap
by Klaus Schmidinger 22 Oct '24

22 Oct '24

The newly refurbished VDR User Counter at https://www.tvdr.de/counter.htm now uses OpenStreetMap instead of Google Maps. If you have a user number and password, please log in at https://www.tvdr.de/cgi/vdr-counter?action=edit (click "Edit my entry") and check if your data is still up-to-date. If you don't remember your user number/password, enter your email address and click "Send me a new password". If you're a VDR user and have not yet registered with the VDR User Counter, please go to https://www.tvdr.de/cgi/vdr-counter?action=register and join the VDR community. Disclaimer: The VDR User Counter is an attempt to find out how many people are actually using VDR, so please register only if you are actually using VDR! Note that there is absolutely no obligation to register yourself in order to use VDR. VDR is free, open source software, so you can, of course, use it without anybody's approval. However, developing a program is more fun if the programmers know that it is being used by a great many people ;-). Have fun! Klaus

Temporarily suspending the video output
by Marko Mäkelä 13 Oct '24

13 Oct '24

I would like to have a function to suspend VDR playback on my Raspberry Pi 2 or 3, so that I could occasionally use the screen for something else, such as a text console. Currently this is impossible because the video overlay would block the view on the text console layer. I can think of several possible ways to achieve this. (1) In the VDR core or in the video output plugin, monitor /sys/devices/virtual/tty/tty0/active for changes and automatically suspend and resume the output based on VDR is running on the active virtual console. The drawback would be: What if I detached the keyboard but forgot to switch the virtual console back, and another family member wants to watch TV? (2) Add a special setting to the video output plugin (rpihddevice in my case), and activate it from the OSD using remote control. (3) Change the VDR shutdown logic in some way, so that when the Power key is pressed, the audio and video output will be disabled immediately, as if the user had been inactive for a long time. The assumption here would be that a shutdown script or the existence of recording timers would prevent an actual shutdown. Years ago, I had written patches to do this. This would be easy to use from the remote control: Just press Power to suspend the output, and any other button to resume it. When the output is suspended, ideally I would like the tuner device descriptor to be closed to save some power. It should only run when needed for recordings or for updating the EPG once in every few hours. Marko

[ANNOUNCE] VDR version 2.7.3 released
by Klaus Schmidinger 12 Oct '24

12 Oct '24

VDR version 2.7.3 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 2.7.2: - Removed defining DEPRECATED_* macros with value 0, because this is the preprocessor's default (suggested by Winfried Köhler). - Fixed error checking in case of large PTS discontinuities (reported by Matthias Senzel). - Fixed handling negative values in cSource::Position() on systems where 'int' is 64 bit (reported by Markus Ehrnsperger, fix suggested by Winfried Köhler). - Fixed expiring of one-time VPS timers in case there is more than one event with the same VPS time (suggested by Markus Ehrnsperger). - The Channel+/- keys can now be used to jump between errors while replaying a recording (suggested by Stefan Hofmann). - Added vdrrootdir and incdir to vdr.pc (thanks to Stefan Hofmann). - Plugins that have been built with API version 5 do not need to be rebuilt.

[ANNOUNCE] VDR version 2.7.2 released
by Klaus Schmidinger 27 Sep '24

27 Sep '24

VDR version 2.7.2 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 2.7.1: - Fix for compilers that don't like non-constant format strings (thanks to Stefan Hofmann). - Deprecated code is now marked with [[deprecated]] to issue a compile time warning when used. - Made APIVERSION independent from VDRVERSION to avoid irritation in case only VDRVERSION is incremented (originally suggested by Winfried Köhler, with contributions from Lars Hanisch and Manuel Reimer). APIVERSNUM is now 30003. - Fixed a problem in cSchedule::Sort(), in case hasRunning was true, but there was no event with RunningStatus() >= SI::RunningStatusPausing (reported by Markus Ehrnsperger). - Silenced a compiler warning with gcc 14.1.0 (reported by Winfried Köhler). - Updated the Italian OSD texts (thanks to Diego Pierotto). - Moved error checking from recorder.c to remux.c. - The number of errors in a recording now represents the number of broken frames. - Now distinguishing between frames with errors and completely missing frames. - Recording errors are now marked in the index file. - Fixed description of cSkinDisplayReplay::SetRecording(). - Errors are now shown as diamond shaped markers in the replay progress display of the default skins. Plugin authors can switch to the new constructor of cProgressBar to benefit from this feature. Of course this only works with recordings that have error information stored in their index file. If you have existing recordings with errors and want them to be displayed in the progress bar, you can re-generate their index file, either by deleting the old index, or by running vdr with the --genindex option. APIVERSNUM is now 30004. - When the index file of a recording is regenerated, errors in the recording are now stored in the index file. - The info file of an edited recording now contains the number of errors in the edited version. Note that this applies only to recordings that have errors stored in their index file. If errors are not stored in the index file, the edited version will have its number of errors set to that of the original recording. APIVERSNUM is now 30005. - Fixed singular when displaying number of errors in the recording info. - Increased the bpp of cProgressBar to 4 to handle all different colors. - Fixed a problem with duplicate events if they are moved to a lower table ID and at the same time get a new event ID (reported by Markus Ehrnsperger). - Plugins need to be rebuilt.

The sole modification is including a new entry to the device ID table, which can be found in `drivers/media/usb/cx231xx/cx231xx-cards.c`. I have verified that both video and audio capture are functioning as expected. Signed-off-by: Rohan Barar rohan.barar(a)gmail.com Thank you for considering my patch! Best regards, Rohan Barar

Crash when deleting source and target recordings while editing
by Marko Mäkelä 18 Aug '24

18 Aug '24

On my Raspberry Pi 2, I observed that VDR 2.6.9 (with the rpihddevice plugin) would hit SIGSEGV due to dereferencing a null pointer: #0 __GI_strlen () at ../sysdeps/arm/armv6/strlen.S:26 #1 0x76a9b434 in __GI___strdup (s=0x0) at strdup.c:41 #2 0x000ff354 in cRecording::cRecording (this=0x196cab0, FileName=0x0) at recording.c:919 #3 0x00100978 in cRecordings::DelByName (this=this@entry=0x1dd13c <cRecordings::recordings>, FileName=0x0) at recording.c:1699 #4 0x000d92f8 in cMenuRecordings::Delete (this=0x17bf200) at tools.h:188 #5 0x000e755c in cOsdMenu::ProcessKey (this=this@entry=0x1963be8, Key=Key@entry=kYellow) at osdbase.c:535 #6 0x000d640c in cMenuMain::ProcessKey (this=0x1963be8, Key=kYellow) at menu.c:4606 #7 0x000749a0 in main (argc=<optimized out>, argv=<optimized out>) at vdr.c:1419 To reproduce: 1. Start cutting a recording "name" (DVB-T2, H.264 in my case). 2. Delete the original recording. 3. Attempt to delete "%name", which still appears in the menu. Note: At the time of the crash, an empty subdirectory "%name" will exist. Because I am not familiar with this part of the code and I don't think that https://rr-project.org would work in this environment, I did not try to find the exact root cause or try to develop a fix. I assume that cCutter would have removed the "%name/2024-08-*.rec" directory as soon as it noticed that the "name" recording had disappeared. It failed to remove "%name" or the corresponding Recordings menu entry. Best regards, Marko
