Getting started with Pi TV HAT and gpio-ir
by Marko Mäkelä 23 Oct '22

23 Oct '22

Hi all, Much of this message would probably belong to some wiki page, along with some photographs that I made. Before starting to write this, I checked https://vdr-projects.github.io and did not find any hardware projects. The hardware section of the VDR wiki at https://www.linuxtv.org does not seem to have been updated for years; it does not mention Raspberry Pi at all, despite it being a viable alternative for more than 10 years. I was an active VDR user from 2004 or 2005, when I built a PC based setup, using a "budget" DVB-T card (Hauppauge Nova-T PCI). That system was never upgraded to DVB-T2; instead, we got a flat screen TV with a built-in tuner. Gradually, as our children got older, recordings were made and watched less often. We mostly stopped using VDR about 10 years ago. Since then, I have made some attempts to "come back", initially, using a Raspberry Pi 2 B and an Astrometa USB DVB-T/T2 stick. This month, I purchased a TV HAT case and the DVB-T/T2 uHAT for my Raspberry Pi 2 B. As far as I understand, the plexiglass TV HAT case should fit the Raspberry Pi 2, 3, and 4. The LED holes next to the MicroSD card slot are on the wrong side for the Pi 2, but everything fits perfectly. I regret that I did not buy the Pi TV HAT earlier. The USB stick is simply garbage compared to it. The Astrometa USB stick switches channels very slowly and the tuner very frequently produces errors in the bit stream, when using a good outdoor aerial that other devices have no trouble with. By design, its infrared receiver will lose messages when a button is being held down, because a 128-byte buffer of the microcontroller would overflow, and there is no way to use it as a ring buffer (I tried). A kernel maintainer came up with some experimental patches that significantly improved the situation, but every few of seconds some key-repeat events were still being lost. Out of that effort, a tiny patch from me was included in the Linux kernel, to have the kernel's LIRC interface set the "repeat" flag for all IR protocols: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… The Pi TV HAT is missing an infrared receiver out of the box. I soldered an IR receiver module to some thin wires, isolating the legs with heat shrink tube. The other ends of the thin wires I soldered to some pads next to the connector: 3.3V at pin 1, ground at pin 6 (or 9), and the signal output to GPIO 18 (pin 12). GPIO 17 at pin 11 would have worked as well. I made the IR receiver module stick out from a vent hole on the top, because my initial attempt of keeping the module inside the transparent lid of the case did not work that well. The module can pick up IR signal some 8 meters away. The software configuration was easy: (1) Add the following line to /boot/config.txt: dtoverlay=gpio-ir,gpio_pin=18 (2) Execute "sudo apt install ir-keytable" (3) Edit /etc/rc_maps.cfg to load a suitable table for your remote control unit. To reuse the old remote control unit that I had, I wrote an entry * * hauppauge.toml (4) Reboot for the config.txt change to take effect. For me, the remote control unit appeared in /dev/input/event0 as well as /dev/lirc0 and some buttons (such as the number keys) would directly work in the /dev/tty1 textual login prompt. For starting up VDR, I used a command like this: vdr -v /var/lib/vdr/video --no-kbd -Prpihddevice -P'remote -i /dev/input/event0' Yes, the Pi TV HAT was detected automatically; I did not have to do anything special. I had previously used the same VDR configuration with an Astrometa USB stick. This is with a copy of https://github.com/reufer/rpihddevice with some critical patches applied. (The issues and a pull request that I opened in January 2022 are still unattended.) The experience with the Pi TV HAT is simply great. The Sony tuner in the Pi TV HAT produces an error-free bit stream and switches transponders very quickly. The kernel GPIO IR driver is rock solid. I think that the user experience is at least as good as with my old PC setup. Some buttons on my remote control unit were unreliable. Using an expired debit card, I was able to pry open the grey Hauppauge remote control unit, starting next to the IR LED. I guess I should upload pictures of the internals somewhere, to help others open theirs. Next, I plan to attach some external storage for recordings. A USB 3.0 NVMe drive would allow faster backups (when detached from the Raspberry Pi 2) and an upgrade to a Pi 3 or 4. On the software side, I am thinking to apply my kernel patch and to write a "kernel LIRC plugin" for VDR that would allow me to use /dev/lirc0 for the input. I would prefer to use the lower-level interface where each IR message corresponds to an event. I do not like the key-repeat timer logic of the kernel's input event driver. And I never liked the user-space lircd. With best regards, Marko

projects.vdr-developer.org might come to an end
by Tobi 31 Jul '22

31 Jul '22

Hi! Over the last years, the projects.vdr-developer.org site was hosted on a server sponsored by Xeatre.tv. This server will now go offline on June, 7'th. Currently there are about 10 projects with activity in the last 12 months. I haven't made a final decision on how to proceed, but I'm leaning towards taking the site offline. In this case I will archive the git repositories on gitlab or github and possibly keep a read-only instance of Redmine on my private vServer for a while. Let me know, what you think. If there are many comments in favor of keeping the site online, I'm sure I can find a solution. BR, Tobias

EPG table 0
by Richard F 17 Jul '22

17 Jul '22

I've just updated to VDR V2.61 after a long time on V2.2, using the same config and the epgtableid0 (2.4.0) plug-in. The issue I'm seeing is that when VDR is restarted, it doesn't seem to be reading/respecting the epg.data file. It's starting an EPG scan and seems to be overwriting table 0 entries from the OTA EPG. So for example this (via xmltv import) E 42885 1657987200 3600 0 FF T The Great British Bake Off S Biscuits and Traybakes D The remaining eight bakers offer Mary and Paul their twists on everything from bakewells to banoffees and brownies, as they face the biscuit and traybake challenges.|Director: Scott Tankard|Producers: Samantha Beddoes, Anna Beattie|Presenters: Mel Giedroyc, Sue Perkins|Category: Reality, Cooking|Episode: 3.4.|Episode: EP013163930033|Stereo: stereo|Subtitles: teletext|Repeat: No G A5 is becoming something like this from the OTA EPG (not same ID I know, just an example) E 18475 1657987200 3600 50 13 T The Great British Bake-Off D Almost halfway through, the remaining eight bakers are faced with biscuits- and the Signature Challenge requires them to produce their favourite traybake. S4/Ep5 G A0 X 2 03 eng X 1 03 und X 3 10 eng Is there something else I need to import into table 0, or some other issue ? Thanks

Termination of ftp.tvdr.de
by Klaus Schmidinger 02 Mar '22

02 Mar '22

Since all versions of VDR are now available at git.tvdr.de, new versions will be distributed exclusively through the GIT, and FTP in general is considered "legacy" and frowned upon (Firefox, for instance, doesn't even support it any more), I intend to shut down ftp.tvdr.de. If you still need something from there, please download it now. If you are mirroring this server you may want to stop doing so, to prevent your local copy from disappearing when files vanish from the server. Klaus

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
