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-2.4.1 and xineliboutput: video and audio freeze
by Peter Münster 06 May '20

Hello, On my vdr-box, I cannot watch some channels. For example when switching to France 2, the image stutters and then freezes after some seconds. And the audio output stops too. I have 2 outputs with some messages: 1.) From stdout/stderr (only some samples, because there are a lot of lines): ffmpeg_audio_dec: not enough data to decode metronom: video jump by -23415 pts. metronom: video jump by 72000 pts. video_out_vdpau: b 0 c 128 s 128 h 0 [ITU-R 709 / HDTV] ffmpeg_audio_dec: not enough data to decode video_out: throwing away image with pts 24396186 because it's too old (diff : 124178). ffmpeg_audio_dec: not enough data to decode metronom: video jump by -48960 pts. video_out: throwing away image with pts 24358421 because it's too old (diff : 286741). ffmpeg_audio_dec: not enough data to decode audio_out: flushed out 0 buffers. ffmpeg_audio_dec: resetting parser audio_out: ao_flush (loop running: 1) set_speed 0. video_out: new speed 0. set_speed 1000000. video_out: new speed 1000000. audio_out: new speed 1000000. audio_out: flushed out 0 buffers. audio_out: flushed out 0 buffers. ffmpeg_audio_dec: resetting parser audio_out: ao_flush (loop running: 1) metronom: prebuffer=14400 pts. metronom: video discontinuity #78, type is 3, disc_off 0. metronom: waiting for audio discontinuity #78... ffmpeg_audio_dec: resetting parser metronom: audio discontinuity #78, type is 3, disc_off 0. metronom: vpts adjusted with prebuffer to 24818015. metronom: prebuffer=2000 pts. metronom: prebuffer=14400 pts. video_out_vdpau: b 0 c 128 s 128 h 0 [ITU-R 470 BG / SDTV] metronom: prebuffer=14400 pts. set_speed 0. 2.)

VDR findet S13E nicht mehr nach Upgrade
by Harald Milz 01 May '20

01 May '20

Servus, ich brauche ausnahmsweise mal Hilfe ;-) Nach längerem habe ich mich endlich aufgerafft, meinen VDR von Ubuntu 14.04 / Kernel 4.4.0 / vdr-2.2.0 / dddvb-0.9.32 hochzuziehen auf Ubuntu 18.04 / Kernel 4.15.0 / yavdr-2.4.0 / dddvb-0.9.38 (latest aus git). An den Configs habe ich nichts geändert. Die Karte ist eine DDBridge V 6.5 mit 4 Tunern. 1 und 2 liegen auf Astra S19.2E, die beiden anderen auf Hotbird S13E. Die LNBs sind zwei Quad von Kathrein, von denen jeweils nur die ersten beiden Ausgänge belegt sind. Die disecq.conf ist die Standardeinstellung dafür wie aus dem Wiki, was immer prima funktioniert hat. Aber jetzt nicht mehr: Kanäle auf Astra werden ohne weiteres gefunden, aber der VDR versucht nun S13E-Kanäle mit Tuner 1 oder 2 zu finden, was natürlich scheitert: Apr 30 17:41:47 vdr vdr: [16550] switching to channel 1 S19.2E-1-1019-10301 (Das Erste HD) Apr 30 17:41:47 vdr vdr: [16851] device 1 receiver thread started (pid=16550, tid=16851, prio=high) Apr 30 17:41:47 vdr vdr: [16852] device 1 TS buffer thread started (pid=16550, tid=16852, prio=high) ... Apr 30 17:42:10 vdr vdr: [16550] switching to channel 61 S13.0E-318-12400-8511 (Rai 1) Apr 30 17:42:10 vdr vdr: [16852] device 1 TS buffer thread ended (pid=16550, tid=16852) ... Apr 30 17:42:10 vdr vdr: [16851] device 1 receiver thread ended (pid=16550, tid=16851) Apr 30 17:42:10 vdr vdr: [16854] device 1 receiver thread started (pid=16550, tid=16854, prio=high) Apr 30 17:42:10 vdr vdr: [16855] device 1 TS buffer thread started (pid=16550, tid=16855, prio=high) Apr 30 17:42:19 vdr vdr: [16554] frontend 0/0 timed out while tuning to channel 61 (Rai 1), tp 210992 Ich hätte erwartet, dass er dafür frontend 2/0 oder 3/0 verwendet. Auf denen wirft er aber ständig Timeouts zu Channels von S19.2E. In /dev/dvb stehen alle 4 Adapter, und der VDR erkennt sie auch (found 4 DVB devices). Möglicherweise habe ich verpasst, weil ich sehr lange nicht danach geschaut habe, dass sich an den diesbezüglichen Configs von vdr-2.2.0 nach -2.4.0 was geändert hat. Wo muss ich hinschauen? Danke! -- You are only young once, but you can stay immature indefinitely.
