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:

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.
