[15:33] <troulouliou_dev> hi where can i sublit /usr/share/dvb-t / dvb-s scan files ?
[15:46] <devinheitmuell-1> troulouliou_dev: send them to the linux-media mailing list.
[16:01] <troulouliou_dev> devinheitmuell-1, and kernel patches to add pid/vid for a new rtl2832u based receiver ?
[16:01] <troulouliou_dev> i can send it too to the mailing list ?
[16:01] <devinheitmuell-1> Yes.
[16:04] <troulouliou_dev> devinheitmuell-1, ok perfect

[20:03] <Notaris> Anyone around who could help me debug why a TechnoTrend TT-TVStick CT2-4400 is not working on my linux box? I am running Debian wheezy with backported kernel 3.16.0-0.bpo.4-amd64 and compiled the media_build driver
[20:04] <Notaris> The kernel messages look ok to my (blind?) eye: http://pastebin.com/6b398fds
[20:04] <TrSqr> let me see
[20:05] <Notaris> Ok. Just tell me what additional info you might need.
[20:05] <TrSqr> yep, looks good, loads the correct firmwares
[20:05] <TrSqr> how does it not work?
[20:07] <TrSqr> I mean, what are the symptoms you are experiencing?
[20:07] <Notaris> Hardware should be ok, as I tested it once on my work laptop. I got a channels.conf and had it working with vlc on the laptop. Now if I use this same channels.conf on my desktop with vlc, I do not get a picture. vlc (started from terminal) is not very verbose, just says [0x1ab3108] main libvlc: VLC wird mit dem Standard-Interface ausgefu:hrt. Benutzen Sie 'cvlc', um VLC ohne Interface zu verwenden.
[20:07] <Notaris> [0x1cdd898] main playlist: stopping playback
[20:07] <Notaris> [0x2345128] main stream error: cannot pre fill buffer
[20:07] <Notaris> ...and does not start playing TV.
[20:09] <Notaris> I am not bound to use vlc for watching TV, any working alternative would be ok.
[20:10] <Notaris> Just don't know where to look for an error.
[20:10] <TrSqr> I'm unfortunately rather vlc illiterate. can just make a simple channel scan using w_scan or dvbv5-scan to see what it says?
[20:10] <TrSqr> is this DVB-T or DVB-C?
[20:11] <Notaris> It has a DVB-T, DVB-T2 and DVB-C tuner and/or demodulator built in.
[20:11] <Notaris> http://www.linuxtv.org/wiki/index.php/TechnoTrend_TT-TVStick_CT2-4400
[20:11] <TrSqr> yes, I know, I've written that page :)
[20:11] <TrSqr> but what are you trying to receive?
[20:12] <Notaris> ok. Sorry, misunderstood the question. I am trying to get the DVB-C signal
[20:12] <Notaris> ...and sure, I can do a w_scan or anything else.
[20:13] <Notaris> I had done a w_scan (some weeks ago, when I bought the stick) before. Tuned through the frequencies for some 15 minutes without finding a single channel. In contrast, when hooked to my work laptop to the same antenna cable, I found all channels which are now residing in the channels.conf.
[20:14] <TrSqr> the thing is, if the application does not support multiple standards for one adapter, you need to change the mode before trying to use it
[20:14] <TrSqr> quite many applications do not still do that
[20:14] <TrSqr> dvb-fe-tool -a 0 -d DVBC/ANNEX_A
[20:14] <Notaris> What also might be important to know, I first had tried the binary driver from Technotrend which was no success either before switching to the media_build driver. Might there be some old closed source stuff interfearing?
[20:15] <TrSqr> that should change the delivery system to DVB-C
[20:15] <TrSqr> based on the dmesg output you should be ok
[20:16] <TrSqr> but if you have a recent w_scan (the one that comes with your distro could be age old), it should handle multiple delivery systems per adapter ok
[20:17] <Notaris> I first had tried directly vlc with no success, than had switched with dvb-fe-tool -d DVBC/ANNEX_A and tried again. No improvement. your suggestion with -a 0 on top also did not help
[20:17] <TrSqr> ok :/
[20:18] <TrSqr> and w_scan -fc does not find anything either?
[20:19] <Notaris> wscan seems to be from 2012: Package: w-scan (20120605-1)
[20:20] <Notaris> http://pastebin.com/ra9wmReF
[20:21] <Notaris> Just started a w_scan run (see beginning in link above). If it is the same as last time, it will take some 15 minutes and not find any channel. Bear with me....
[20:22] <TrSqr> ok.. 2012 is age old :) but maybe it should still work
[20:24] <Notaris> Come on, jessie release is still some weeks ahead and w_scan will seemingly only get updated to a version from end march 2013 :(
[20:26] <TrSqr> proper DVB-T2 support came in the July 2014 release...
[20:26] <TrSqr> but I guess DVB-C should be ok
[20:27] <Notaris> DVB-T2 is not yet broadcasted in Germany. Might come in a few years. Probably even enough for Debian to catch up with......
[20:30] <Notaris> On my work laptop, I am running Ubuntu 14.04 which comes with w-scan (20130331-1), likely the same version that will only come with Debian Jessie in a few weeks. That could explain the non-successful scanning on my desktop. However, does this also explain why playback of TV is not working? I would assume w-scan is _only_ needed for building the channels.conf?!?
[20:31] <Notaris> BTW, 11 minutes and counting of w_scan and no channel yet
[20:32] <Notaris> 850000: sr6900 (time: 12:45) sr6875 (time: 12:48)
[20:32] <Notaris> 858000: sr6900 (time: 12:50) sr6875 (time: 12:53)
[20:32] <Notaris> ERROR: Sorry - i couldn't get any working frequency/transponder
[20:32] <Notaris> Nothing to scan!!
[20:32] <Notaris> So, no channels found... :(
[20:34] <TrSqr> but the laptop using the same driver works, or did that have the closed source driver?
[20:34] <Notaris> Complete console output: http://pastebin.com/AHBRP55t
[20:34] <Notaris> No, on the laptop I only used the open source driver without messing before with the closed source TechnoTrend driver
[20:47] <Notaris> Any other idea what to do? Anyhow, thanks already now for taking time and trying to help out!
[21:05] <TrSqr> I'm quite short on ideas, unfortunately. I'd try compiling a recent w_scan still, but maybe that won't make any difference.
[21:05] <TrSqr> everything looks good, but you just don't get a lock (which you do using the same driver and device on a different PC)
[21:06] <TrSqr> oh, this is the problem:
[21:06] <TrSqr> 44.
[21:06] <TrSqr> [ 5015.713245] si2168 6-0064: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'
[21:06] <TrSqr> [ 5024.543938] si2168 6-0064: firmware version:
[21:07] <TrSqr> something's wrong with the demod
[21:07] <TrSqr> you should see it print the firmware version
[21:08] <Notaris> ok, that means to download the firmware file again from OpenELEC dvb-firmware collection?
[21:09] <TrSqr> http://trsqr.net/olli/dvb-demod-si2168-b40-01.fw
[21:09] <TrSqr> take that, it's a bit newer..
[21:11] <Notaris> Then unplug and replug the DVB-Stick?
[21:11] <TrSqr> we'll update the firmware in OE later when we have a kernel in OE that supports the new firmware format, but so far there's still the "old" one
[21:12] <TrSqr> Notaris, that should do it.. or just remove the module and modprobe it again
[21:14] <Notaris> Whow! That was quite an experience. Unplugging and replugging almost seemed to crash the computer: http://pastebin.com/vM8pVdWu
[21:15] <Notaris> Also the "old" kernel problem?!?
[21:16] <TrSqr> hmm.. no idea really.
[21:17] <Notaris> I could do a reboot to start from a clean state... does that sound reasonable?
[21:17] <TrSqr> yep, definitely :)
[21:17] <Notaris> Ok, I'll be back ;) Thanks for all the help, give me a minute or two.....
[21:18] *** Notaris has quit IRC (Quit: Notaris)
[21:27] <Notaris> Now the first part looks good: http://pastebin.com/awNfVRt3
[21:27] <Notaris> What do I do to make it load the firmware: Start w_scan again?
[21:27] <TrSqr> yep. anything that tries to use the tuner
[21:28] <Notaris> Looks great!
[21:28] <Notaris> http://pastebin.com/PJa7cZzs :)
[21:28] <Notaris> Firmware version 4.0.11
[21:28] <TrSqr> yes, much better now
[21:29] <TrSqr> so, does it work?
[21:30] <Notaris> w_scan output is different from last time. No channel found yet (that was also some 10+ minutes into the scan on the laptop), but I am quite hopeful! I'll let you know as soon as w_scan is through!
[21:31] <Notaris> Now there is also the little green LED light working on the stick, which was not the case before on the desktop! :)
[21:33] <TrSqr> yep, I use the same tuner in my living room for dvb-t and dvb-t2
[21:41] <Notaris> w_scan is finding channels. :) That looks excellent. DVB-T is not a real alternative, the signal is coming from an antenna only 3,3 km away, but I never received all available channels, no matter which hardware I tried.... :(
[21:44] <TrSqr> allright, sounds good then!
[21:46] <TrSqr> anyways, time to get some sleep - if it still doesn't work it has to wait until tomorrow.
[21:46] <TrSqr> but it will, no worries :)
[21:46] <Notaris> Ok. Thank you very much for your help!!!!
[21:46] <Notaris> I am quite confident that it will work!
[21:47] <TrSqr> yep. not a problem!
[21:47] <Notaris> Good night!
[21:50] <Notaris> It works! Seems that it was indeed the firmware file (corrupted during download?!?!)
[23:02] <nox-> crope, ping
