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

20 Years of VDR / Announcing "GeoTagger"
by Klaus Schmidinger 29 Apr '20

29 Apr '20

Twenty years ago today, I released the first version of the VDR source. A pretty long time, in which much has happened. Back then a VDR was something special, while today it's just an ordinary device. But still it feels good to be able to tweak things yourself. Lately it's been rather quiet from my side, regarding the VDR development. For one this was because it just works fine in every day life. But I was also busy working on a totally different project. I wanted to add/adjust the GPS coordinates in the many photos that piled up over the years (partly scanned from negatives). Unfortunately there was no application available under Linux that really fit my needs (maybe I just missed that one great program ;-). So I decided to do some development of my own, and today, for the 20th "birthday" of VDR, I'd like to present the result: http://www.tvdr.de/geotagger This is the very first version to go "out in the wild", so chances are there will still be some quirks. So far I have tested it on Linux (openSUSE Leap 15.0) and Mac OS 10.13. I can't test on Windows, because I don't have such a system. Maybe it can be of some use to some of you out there, too. Please send problem reports directly to me, so we don't clog this mailing list. Klaus

>Back then a VDR was something special, while today it's just an ordinary device. Well, I am sitting here installing vdr yet again on a new pc :) It might be old, it might be this and that, but to me it is still the best there is. Simple, efficient and works all the time. I have been using it since the first version, and I will probably use it for as long as it can be used. So again, thank you Klaus! Josce
