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

French DVB-T Channel IDs vs. EIT Channel IDs
by Patrick Boettcher 25 Jan '20

25 Jan '20

Hi list, since some time (1-2 years) I noticed that the DVB-T channels do not show EPG anymore. I'm not sure what is the root-cause: either it was the migration of French DVB-T to HD (in 2016) or an update of VDR. Anyway, this morning I took the time to figure out what is wrong and here is what I found. In short, the channel-ID generated from the one received in the EIT does not correspond to a known channel-ID from the channel list, and VDR drops the whole section: In cEIT::cEIT (from eit.c) we see tChannelID channelID(Source, getOriginalNetworkId(), getTransportStreamId(), getServiceId()); cChannel *Channel = Channels->GetByChannelID(channelID, true); and channel is NULL in my case. I added some debug prints to GetByChannelID() in the search loop: printf("sid: %d == %d, %s, %s %d\n", Channel->Sid(), sid, (const char *)ChannelID.ToString(), (const char *)Channel->GetChannelID().ToString(), Channel->GetChannelID() == ChannelID); And here is an example of what I get: sid: 517 == 517, T-8442-2-517, T-0-506-517 0 The internal channel ID of vdr reads T-0-506-517. 517 is the SID, 506 is the radio-channel frequency in MHz. This is the right internal channel for this EIT-section. The EIT-channel-ID is telling me that 8442 is the original network ID and 2 might be the radio-channel ID. I tweaked the operator==() of ChannelID to make it work, but not in a contributable manner. How should this be fixed correctly? Is this a regression introduced somewhere? Can it be solved by configuration? Thanks for any help. best regards, -- Patrick.

Inofficial GIT mirror
by Manuel Reimer 26 May '19

26 May '19

Hello, I've created an inofficial VDR mirror on Github. https://github.com/VDR4Arch/vdr The target of this mirror is to collect all changes done by Klaus. Not only releases but also every "official" patch. This allows you to keep a local VDR copy up-to-date by just running "git pull" from time to time. It also helps to do own changes or to develop own modifications using git features. Feel free to create your own forks for this. As this mirror is meant to have official content only, all pull requests will be closed without even commenting. The "upstream repo" will only be updated by a very small "group" of admins (currently only myself) and will only contain official, unmodified, patches and releases. If you want to contribute to VDR, the only way is to create a patch file from your final work and send this to Klaus. https://git-scm.com/docs/git-format-patch Manuel

A couple of noob questions on VDR + vaapidevice (output plugin)
by Frantisek Rysanek 12 May '19

12 May '19

Dear VDR developers and fellow users, you may have noticed my rather inappropriate thread at the linux-media mailing list... I'm trying to build a Linux HTPC for DVB-T2 and I'm struggling :-) I like the VDR project's philosophy / focus and I'd love to use the VDR as the software to run my HTPC. I understand that the primary output device with the VDR is a PCI DVB card with an integrated MPEG decoder - any alternative output plugins are in fact 3rd-party addons / stand-alone software projects. Well I'd like to try to use the IGP's decoding capabilities. Where I am at: At this stage I'm still playing with a cheap USB DVB-T2 dongle on borrowed or scrap hardware. Right now I have a Skylake-based machine, with Ubuntu 19.04 installed on some spinning rust. I'm compiling any parts that I need to on that same box. I have installed vdr-2.4.0 from the distro repo and I have also compiled my own from source, including all the development patches as of late April 2019. For the screen output, I'd like to use the "vaapidevice" plugin by rofafor/pesintta - compiled from source from this repository: https://github.com/pesintta/vdr-plugin-vaapidevice On the skylake machine, the vaapidevice output plugin seems to work. I have a good quality DVB-T2 mux at my antenna input. The tuner is a re-labeled Mygica T230C2, sold under a local private brand = Linux driver cxusb, which I had to take from CrazyCat, because the mainline kernel doesn't support this latest Mygica HW revision. But the CrazyCat driver stack works fine for me, in Linux 5.0.10. I'm still "not completely there yet". I'm facing the following issues: The vaapidevice video playback "stutters". As if short (sub-second) sequences of the movie get repeated. (For comparison, VLC plays the stream just fine, smoothly.) I have a possible theory: I'm still trying this on the PC machine's built-in LCD, which likely runs at a 60Hz frame rate - while the HEVC material from DVB-T2 is nominally at 50p I guess (the old DVB-T was 50i). Maybe the VLC can somehow cope with that (perform rate conversion on the fly) but the vaapidevice plugin cannot. Maybe I should attach a TV as a second display and set the PC's HDMI frame refresh rate to 50 Hz. Another issue is: how do I control the OSD on the vaapidevice output, if I only have a PC keyboard and mouse? I've found several introes (mostly copies of the VDR's MANUAL, I guess) that all speak about Lirc, how to configure the remote control buttons. Is there some way to control the OSD from PC keyboard? To be absolutely precise, I was even wondering if a miniature wireless PC keyboard (with radio transmission) wouldn't be more comfortable to use than the notoriously unreliable IR remotes :-) Any help would be appreciated...

Hi, Asrock do a range of mATX cards with integrated Gemini Lake, but none with PCI slot, just 3 x PCIe 1x. Klaus (VDR author), is using the J4105M, with vaapi, but be aware that not all Asrock boards play well with Digital Devices cards. This one seems to and DD are looking into it - see this thread: https://www.vdr-portal.de/forum/index.php?thread/132649-i2c-timeouts-mit-dd… Regards, Richard

Hello Karim, ...the parallel PCI slots really seem to have gone out of vogue... I work as a service techie for *industrial* PC's - a niche that is rather backward in its tastes :-) and if you take a look at e.g. the portfolio of Advantech, you may find ATX boards with LGA1151 with more than one PCI slot. But you definitely won't like the price tag. Other than that, the BIOS nowadays tends to be a pretty normal AMI APTIO, UEFI and legacy booting supported, but you won't find any overclocking features in the BIOS SETUP. Hmm... in the recent generation, only the AIMB-786 has two PCI slots, and that's full-size ATX. In the mATX format, if you go back to SkyLake/KabyLake, you may find a board with a single parallel PCI slot... Apparently the PCI slots are on their way to extinction, following the ISA slots :-) In the "industrial" segments you can find other formats that have parallel PCI, such as PICMG hardware or maybe an external expansion box, but I believe that's even further away from an HTPC budget and living-room aesthetics :-) Frank On 8 May 2019 at 22:39, Karim AFIFI wrote: > Dear Franck, > > Thanks a lot for all theses precisions !

Questions about good hardware to view VDR 4K
by Karim AFIFI 08 May '19

Hi, I am looking for an ATX motherboard with PCI and PCIE slots, for using with new VDR 4K (PCI S2-3200+CI and PCIE Hauppauge quad), and ASTERISK (PCI Digium FXO/FXS card). At the beginning, I was thinking about an Intel 1151 socket (for best vaapi support), like this one (*): https://www.asus.com/Motherboards/TUF-H310-PLUS-GAMING/HelpDesk_Manual/ Unfortunately, I noticed HDMI is v1.4, with 4k@24Hz only ! I am afraid that I need to add a PCI-E video card to achieve 4k@60Hz. Is it correct ? If so, I have two questions : 1) could you advice about fanless + VAAPI compatible product ? 2) any feedback about best plateform/chipset : AMD vs Intel ? Thanks a lot. Karim (*) using with low TDP quad core CPU, for example i3-8100T.
