bad characters in epg.data
by Peter Münster 07 Dec '15

07 Dec '15

Hi, It seems, that the encoding of the epg.data file is utf-8, but sometimes, there are lines like this: C S19.2E-133-3-263 18:00 GRÖD - RBS The "Ö" is one byte (0xD6) that seems not conform to utf-8 encoding. How could I avoid such characters in the epg.data file please? TIA for any hints, -- Peter

Dear TV card experts - I need you help
by Mr Andersson 03 Dec '15

03 Dec '15

Hi, Let me start of by presenting myself. I am a Computer Engineer and a business man, looking to launch a service where TV channels from primarily satellites will be made available to the public. I am trying to garner more info on this topic but it is so difficult to figure out the requirements are and what the best/most optimal solution would be. I'd appreciate if you could take some time to help me figure out what is out there, and where our focus should be on first. >From linuxtv i understand that there are a number of cards one could use for this purpose. I am interested in good quality cards, that allows us to record and present as many channels as possible for as little money as possible. Most cards out there supports maximum 4 channels per cards. Some I've looked into costs around 200 USD per card and for 2000 channels, excluding all other hardware, that would cost around 100 000 USD. Do you know of any suitable cards to look into for this matter? Also, what software solutions would one need for the tv card up to the presentation part? Also, maybe there are already services out there which would allow us to get access to channels content, without setting up a satellite and such cards. For instnance, free linux tv services with already existing content. However, relialibilty is the key here, and channels cannot come and disappear. What else would one need to consider in order to provide such a solution? Also, do you know of other similar existing and competing solutions out there already? I know of some of these sites, but non of them are comprehensive or good enough. If you were to help out and become a valuable contributor, you will indeed be rewarded with shares and money generated from this project. I can't go into great detail now what those plans are, but your help will certainly not go unrewarded, especially if you were to become more involved, whether as an consultant or as an active participator. I appreciate your time, and hope that you are able to shed some light on some of these questions, and possibly others.

linuxtv.org downtime around Mon Nov 30 12:00 UTC
by Johannes Stezenbach 30 Nov '15

30 Nov '15

Hi, the linuxtv.org server will move to a new, freshly installed machine tomorrow. Expect some downtime while we do the final rsync and database export+import. I'm planning to start disabling services on the old server about 30min before 12:00 UTC (13:00 CET) on Mon Nov 30. If all goes well the new server will be available soon after 12:00 UTC. The IP address will not change. Johannes

TT S2 6400 card vdr and no video/recording on one particular channel
by Richard Scobie 29 Nov '15

29 Nov '15

I am using vdr and a TT S2 6400 card, along with the latest versions of vdr, all related drivers, firmware and plugin, very sucessfully for some time now, except for one channel, which will not decode the video - audio is fine. I have spent some time with dvbsnoop and DVBInspector, trying to find out what is wrong, but am now out of ideas and wondered if you could offer some suggestions. If I get vdr to record this channel, nothing is recorded and likewise if I try to stream the channel to MPlayer on another machine using streamdev-server, I get nothing and this is the output: Cache size set to 2048 KBytes Cache fill: 15.41% (323172 bytes) libavformat version 55.8.102 (internal) TS file format detected. Cache empty, consider increasing -cache and/or -cache-min. [performance issue] VIDEO MPEG2(pid=308) AUDIO MPA(pid=256) NO SUBS (yet)!

[performance issue] Cache empty, consider increasing -cache and/or -cache-min.

DVBInspector confirms the video stream is H264. What is it that I should be looking for wrong in the stream, that vdr will not record this channel or pass the video stream through the system? Thank you for anything you can offer. Kind regards, Richard Scobie

Raspberry Pi, satip, MLD
by Nicolas Huillard 15 Nov '15

15 Nov '15

Hi all, I still have a problem with my new setup: * Raspberry Pi B (256MB system + 256MB video) * MLD 5.0.0 testing distribution (http://www.minidvblinux.de/) on a 4GB class 6 SD card, using VDR 2.2.0.203-207 * vdr-plugin-rpihddevice (from MLD 1:2015.08.24-37+2.2.0.203) * Octopus Net (firmware 1.0.55) : Linux VLC shows TV channels without problems * vdr-plugin-satip (from MLD 2015.09.19-20+2.2.0.203) * recordings on an NFS share (works for playing, didn't test recording) * the Raspberry is powered from one of the 5V output from the Octopus, which provides enough power for the CI interface, which seems Playing live TV works great, until some point a few dozen minutes later, where some errors start to appear in /var/log/messages: Oct 25 10:51:59 vdrpi user.err vdr: [17414] ERROR: 1 ring buffer overflow (940 bytes dropped) Oct 25 10:52:01 vdrpi user.info vdr: [17414] SATIP: Detected 1 RTP packet errors [device 0] Oct 25 10:52:05 vdrpi user.err vdr: [17414] ERROR: 496 ring buffer overflows (652736 bytes dropped) Oct 25 10:52:11 vdrpi user.err vdr: [17414] ERROR: 584 ring buffer overflows (768544 bytes dropped) Oct 25 10:52:17 vdrpi user.err vdr: [17414] ERROR: 584 ring buffer overflows (768544 bytes dropped) Oct 25 10:52:23 vdrpi user.err vdr: [17414] ERROR: 580 ring buffer overflows (763280 bytes dropped) Oct 25 10:52:28 vdrpi user.err vdr: [17413] rpihddevice: [libav] Header missing Oct 25 10:52:28 vdrpi user.err vdr: [17413] rpihddevice: failed to decode audio frame!

It's usually not fixed until I power cycle the pi. I don't know were to look from here. Options are: * the satip plugin may not be the latest one (but the version number is unclear and the MLD forum is all german-speaking, which is a problem for me) * the ethernet interface may miss packets even though it does not report any packet loss (I changed the cable -quality and length- without success) * the power provided to the rpi may be enough, but I don't know about temperatures (the video core reports 54°C, but the ethernet chip may be too hot) * maybe the Octopus does not provide a proper stream, or the problem comes from the VDR core or the rpihddevice output... Since I'm new to rpihddevice, satip and MLD, and didn't stress previous Raspberry Pïs before, even though I use VDR since a dozen years at least, I'm really lost here. Latest test: a few second after switching some channel, the image froze, sound looped, and the pi was not reachable anymore through SSH, even though the octopus still reported the live stream and the network LEDs on the pi was still blinking. Hardware problem, network driver problem ? TIA, -- NH

Frequency as float in channels.conf
by Zsolt Barat 30 Oct '15

Dear List, I need to change the frequency value in channels.conf to a float value xxxxx.75. But since only INT values are allowed here I wonder how to achieve this. Any advice? Thanks and regards Zsolt

I have two DXR3 cards if anyone has a need for one. Avitus brand, 32bit PCI I've had them a long time, not used in years but kept just in case. No guarantee they are working now - but no reason why not :) Post to UK/EU only Andy

Softhddevice, 10 dupes per second
by Teemu Suikki 28 Oct '15

28 Oct '15

Hi! I was recently using Yavdr with no real problems, but now I decided to build my own VDR system on top of Linux Mint. Main reason was that Yavdr stable still doesn't have vdr 2.2.0.. I've got everything working nicely, but I have weird "duped frames" problem with softhhddevice. Video and audio are fine and nicely in sync, and usually you can't see anything wrong. But fast moving objects sometimes have "tearing" and jerky movement. Also if I open Softhddevice stats from the VDR main menu, I see that "duped" field increases steadily maybe 9-10 per second! "dropped" and "missed" stays at zero usually. There is nothing special on the log. Sometimes I get logs like this: Oct 26 01:09:42 puucee vdr: video: slow down video, duping frame Oct 26 01:09:42 puucee vdr: video: 22:17:22.060 +55 311 0/\ms 23+7 v-buf Oct 26 01:10:29 puucee vdr: video: slow down video, duping frame Oct 26 01:10:29 puucee vdr: video: 22:18:09.380 +53 285 0/\ms 26+7 v-buf But as you can see, these are almost a minute apart, and the actual "duped" count increased by several hundreds already during that time. So this logged "duping" is normal a/v sync, what I see is something different. This is VDR 2.2.0, and quite recent softhddevice from yavdr ppa: 1:0.6.1rc1.git20150924.1231-0yavdr0~trusty And the very same hardware worked just nicely with full yavdr install, with vdr 2.0.x and some old version of softhddevice. Oh, and I have nvidia GT210. -- Teemu Suikki http://www.z-power.fi/

Unable to compile media_build_experimental drivers on Debian stable
by Matthias Lötzke 19 Oct '15

19 Oct '15

Hello All, I has been using http://linuxtv.org/hg/~endriss/media_build_experimental for quite some time now. Until recently I never encountered a problem. Now I can't build any more: > make -C /home/matthias/tmp/media_build_experimental/v4l > make[1]: Entering directory '/home/matthias/tmp/media_build_experimental/v4l' > scripts/make_makefile.pl > ./scripts/make_myconfig.pl > perl scripts/make_config_compat.pl /lib/modules/3.16.0-4-amd64/source ./.myconfig ./config-compat.h > creating symbolic links... > xargs: ln: Too many levels of symbolic links ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > Makefile:264: recipe for target 'links' failed > make[1]: *** [links] Error 126 > make[1]: Leaving directory '/home/matthias/tmp/media_build_experimental/v4l' > Makefile:28: recipe for target 'all' failed > make: *** [all] Error 2 > build failed at ./build line 491. I am using Debian stable with Kernel 3.16.0-4-amd64. Some hundreds maybe thousands of symlinks are being created where the build fails. Any solution or hint would be highly appreciated. Best regards Matthias
