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

vdr not working in Raspbian 10

Hello, I've installed vdr from Raspbian packages, to use it with Kodi. I've updated channels.conf by using w_scan2 for a DVB-T2 dongle. TV channels are found. But I try to watch some channel and I get no data. Tried with two clients Kodi software with its VDR plugin (screen interface) and with vdradmin-am (web interface). What can I check to find the problem? Notes: - TV dongle works; if I stop vdr service and use GUI applicacion Kaffeine, I can watch all TV channels. - I see VDR service attending TCP ports 34890 (VNSI), 6419 and 2010 Thank you. -- Narcis Garcia __________ I'm using this dedicated address because personal addresses aren't masked enough at this mail public archive.
