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 system on Raspberry pi vs these all in one systems
by Timothy D. Lenz 28 Sep '20

My mom (82 years old) is still using a VCR with a tuner box. We are concerned about it wearing out, the tapes no longer being sold, etc.. She just spent $65 on a 9 pack of tapes from Amazon that could have gone to a new setup and she is saying she wants to get another VCR for backup. But they haven't been made in years, so it would already be used. I have a linux computer running VDR with a couple of dual ATSC dual tuner cards. But it needs to be rebuilt/reinstalled and I haven't messed with it in so long, I would have to learn it all over again and I'm not as good at figuring stuff out as I used to be and money is tight. You can get VDR/Linux images ready to go for a Raspberry pi which cost about $35. Add a USB Tuner and a USB drive and you have a digital recorder system. And if I ever get mine rebuilt, they could be linked and share tuners and drive space. But it's complicated and time consuming to setup for me atm. These ready made units would be simpler to get going, but a good one would cost more and be more complicated for her to use. I still have to setup timers for recording with the VCR. I'm looking for recommendations/options/opinions. While the local over the air guide is mostly a mess, sometimes not sending out the prime time data till nearly noon of that day, we'd want to avoid having to sub to any service to keep cost down. Needs to be local recording, be able to use local guide data and when needed setup blind recordings as done on VCRs, and would be nice if you could plug and remove USB drives/sticks for longer term storing recordings. From what I've seen, these ready made systems don't really like media swapping.

satip plugin and rtp over tcp
by linuxtv at ncs-online 07 Sep '20

Hi, according to the description the plugin supports rtp-o-tcp. Unfortunately the payload is not transferred via tcp, but like with unicast via udp. There is no difference between unicast and rtp-over-tcp. Is this a bug or did I do something wrong with the settings? The current settings are as follows: satip.CICAM = 0 0 satip.DisabledFilters =. satip.DisabledSources =. satip.EnableCIExtension = 0 satip.EnableEITScan = 0 satip.EnableFrontendReuse = 1 satip.OperatingMode = 3 satip.TransportMode = 2 Version is 2.4.1 -Carter
