Making VDR run under Systemd
by Marko Mäkelä 28 Nov '22

28 Nov '22

Hi all, I was an active VDR user from about 2004 to 2010 when my children were younger and there was a need to record TV programs for them. The old setup was more or less abandoned when I got a smart TV and the family started to use video streaming services. Some years ago, I got a Raspberry Pi 2 B and an Astrometa DVB-T2 USB stick that also includes an infrared receiver. Because its bundled remote control unit (RCU) has much fewer buttons than the one that I got with the Hauppauge Nova-T PCI 90002 years ago, I configured lircd to translate the RC5 codes from the old RCU. For output, I am using rpihddevice. Yesterday, I upgraded to VDR 2.5.6 and rpihddevice 1.0.4 from git://projects.vdr-developer.org/vdr-plugin-rpihddevice.git while keeping the rest of the Raspbian 9.13 mostly intact. I installed the self-built software simply by replacing the original /usr/bin/vdr that was part of the distribution's vdr 2.2.0 package, and copying the plugin to /usr/lib/vdr/plugins/. It might not be the cleanest solution, but it worked for me. I had some trouble with Systemd, which I resolved by creating a configuration file: # cat > /etc/systemd/system/vdr.service << EOF [Service] Restart=on-failure RestartSec=1s ExecStart=/usr/bin/vdr TimeoutStartSec=infinity EOF # systemctl daemon-reload # service lightdm stop # service vdr start I did not double-check it, but I understood that this could entirely bypass the /etc/init.d/vdr script, which would invoke the runvdr script (which normally runs vdr in a loop). If I choose Restart from the VDR menu, systemd will restart it nicely. I did not configure the Power button yet. Currently, VDR complains that no -s parameter is given when I press the Power button on the RCU. Ideally, I think that VDR should suspend the live video output and somehow inform Systemd that the entire system may be suspended, as far as VDR is concerned. (Of course, only if there are no recordings or remote connections active to VDR.) Then, if nothing else prevents the system from being shut down or suspended, Systemd would do it based on its configuration. Years ago, I developed some patches and configuration at https://iki.fi/msmakela/software/vdr/ to achieve something like this on my old system, and I would now like to revive this somehow. Ideally, the Power button would shut down the DVB receiver and display some indication on the OSD or the video frame buffer that the output has been suspended. If my Raspberry Pi were not an "always-on server" that runs some other services as well, I might want to reimplement the "wake-on-RCU" hardware that is generating a wake-on-LAN signal via the Nova-T PCI card, possibly by extending https://spellfoundry.com/product/sleepy-pi-2-usb-c/ or a similar product that would implement a wake-on-timer for the Raspberry Pi. Then, the system would power up nicely either by RCU or by a recording timer. Integrating the wake-on-timer logic with Systemd could be another challenge. I might try this on PC hardware, which already supports wake-on-timer out of the box. A quick search turned up a promising starting point: https://www.freedesktop.org/software/systemd/man/systemd.timer.html The motivation of this exercise is to have a stand-alone VDR front/back end installation that plays nicely with Systemd, without reinventing any logic around scheduling, startup, and shutdown. Maybe one day, once some more progress has been made with Wayland and when using a Raspberry Pi model with more GPU memory, one could press the Power button on the RCU and have the live TV pop up either fullscreen or in a window, on top of the graphical desktop (which would be available for generic use). Best regards, Marko

VDR packages in Debian and e-tobi.net
by Tobi 15 Jan '22

15 Jan '22

Hi! To my shame, I have rather neglected the maintenance of the VDR and VDR plugin packages for Debian and e-tobi.net over the last 2 years. I am in the process of catching up. However, I would like to get rid of some plugins where nothing is happening upstream anymore. Which plugins do you consider indispensable and would like to see them continue in the official Debian and/or e-tobi.net Debian repositories? BR, Tobias

by Klaus Schmidinger 04 Jan '22

04 Jan '22

VDR version 2.6.0 is now available at the official VDR GIT archive git://git.tvdr.de You can get the latest stable version with git clone --branch stable/2.6 git://git.tvdr.de/vdr.git If you want to download the source as a tar archive, use http://git.tvdr.de/?p=vdr.git;a=snapshot;h=refs/tags/2.6.0;sf=tbz2 A summary of all the major changes since the last stable version can be found at http://www.tvdr.de/changelog.htm There is also a new version with important fixes in the stable/2.4 branch, for those who don't want to or can't switch to version 2.6 at this time: http://git.tvdr.de/?p=vdr.git;a=snapshot;h=refs/tags/2.4.8;sf=tbz2 When updating from an earlier version of VDR please make sure you read the INSTALL and MANUAL files that come with the VDR source _before_ doing so! Please make sure you have backup copies of all your configuration files, and verify carefully that your timers will be set to the correct channels after switching to this new version. Thanks to the many people who have contributed in the making, testing and debugging of this new version of VDR, and also to all users who just enjoy VDR! Please also visit the VDR homepage at http://www.tvdr.de and VDR's facebook page at https://www.facebook.com/VideoDiskRecorder Have fun! Klaus

Trouble with DVB-T2 on frontend 1
by Marko Mäkelä 03 Jan '22

03 Jan '22

Hi all, I recently got a USB adapter "Astrometa DVB-T2" that I would like to use with VDR. It comprises two frontends: /dev/dvb/adapter0/frontend0: Realtek RTL2832 (DVB-T) /dev/dvb/adapter0/frontend1: Panasonic MN88473 (DVB-T2 and DVB-C) I guess it is similar to this one; just a slightly different plastic case with some more ventilation holes: http://blog.palosaari.fi/2014/09/naked-hardware-18-astrometa-amdvb-t2-v2.ht… The hardware appears to work fine, once I copied the /lib/firmware/dvb-demod-mn88473-01.fw from somewhere. The firmware upload has failed at least once on the Raspberry Pi 2 (using Linux 4.9.59), but never on another machine that runs a 4.13.0 kernel. I did not yet get the infrared remote control to produce anything in evtest. With dvbv5-zap (after running dvbv5-scan), I can tune into DVB-T2 channels like this: dvbv5-zap -a 0 -f 1 -c dvb_channel.conf 'Yle TV1 HD' -r After this, I can play the video and audio stream on the Raspberry Pi 2: omxplayer /dev/dvb/adapter0/dvr0 Unless I explicitly specify the options -a 0 -f 1, then dvbv5-zap will fail to find any DVB-T2 senders, because it apparently defaults to frontend0, which is DVB-T only. In VDR 2.3.8, I have only been able to view DVB-T from the first frontend. When I did a trick and renamed /dev/dvb/adapter0/frontend1 to frontend0 before starting VDR, VDR no longer complained that the DVB-T2 channels (which I converted from the dvb_channel.conf to channels.conf with dvb-format-convert) not being available, but it did not seem to receive anything from these channels either. Also, after using dvbv5-scan or dvbv5-zap, I sometimes have to invoke w_scan to "reset" the hardware so that VDR can receive DVB-T channels. I would like to receive and record DVB-T and DVB-T2 on this setup. I am willing to try patches or do some programming myself, but I would appreciate some hints to get started. Marko
