After sleeping on this, it could indeed be helpful to have a network id entry at dtv-scan-tables. The most complex part would be to add support for this new field at the scanning tools, to allow them to auto-detect the need of a network ID and to identify what's the right ID to be stored. The tuner algorithm would need to be different, and the file output logic could only happen after parsing the full file. -- You are receiving this mail because: You are watching all bug changes.

Committed on 21/06/2016 at 00:35. Pushed by mauroc into branch 'master'. dvbscan: add an option to handle other NIT tables Specially for DVB-C, Kaffeine should allow the user to also seek for new transponders at the other NIT tables, as it may have other transponders that are not shown at the main NIT table.

No, but it shouldn't be hard to get the channels from there using the command line. It should be almost identical to what dvbscan found.

It could, but I don't see any advantage. It will still need to parse the other NIT tables, as other places using the same scan file could be using different transponders. > Adding a text-field to the device tab would also be a possibility. The problem is that the screen is already too crowd on devices that support multiple delivery systems, like this one: https://mchehab.fedorapeople.org/kaffeine_screenshots/tmp/kaffeine-terrestrial-cable.png The problem is that the usage of other NIT tables should happen per delivery system type. So, a frontend that support 3 different delivery systems (like the one shown on the above image) would need 3 extra lines for a button to enable "all other network tables" or 6 lines if we also add text input field for the network ID(s) that will be used. To make it even worse,, the Kernel currently maps as two frontends single devices that support both Satellite and Cable (or Terrestrial) delivery systems. We'll eventually fix this bug. So, a single device could support up to 8 different delivery systems (right now, there are devices with 6 different delivery systems on the same frontend). As some people use Kaffeine with 21:9 monitors, adding those extra lines could be a problem. So, I'm actually thinking that I to add an extra button (and eventually a combo box) at the channel scan window that would make it parse the other NIT tables. That would avoid polluting the channel configuration tabs. -- You are receiving this mail because: You are watching all bug changes.

The normal NIT table has ID = 0x40 and it is just one table, and, on your case, it lists 12 transponders. The "other NIT" is actually a series of different extensions, all identified with Table ID 0x41, bu with different extension IDs. Each extension provides a set of transponder frequencies. The total amount of transponders there is 83 transponders. If it gets just one of those tables, the number of transponders will be less than 83, speeding up the tuning. So, for a final patch, it is likely interesting to add some options to avoid the user the need of scanning transponders that will never be available for him, e. g. allowing them to completely disable other NIT or to filter just one (or a few?) other NITs.

It makes Kaffeine to use the other NIT tables. That makes it to get 83 transponders, but I'm not sure if those transponders are really there. Please check if it makes any difference. Please notice that parsing other NIT tables is something that we don't usually want, as those tables are meant to carry on frequencies for other Satellites and other networks. However, on DVB-C, nothing really prevents some carrier to re-use for its own purpose. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=364298 --- Comment #9 from Mauro Carvalho Chehab --- Ok, it is not a timeout issue. I need to check if Kaffeine is getting all transponders. I found a bug there, that might be causing some troubles, but I suspect that the issue is not solved yet. Could you please compile Kaffeine from the git tree, at either one of the sites below: https://git.linuxtv.org/mchehab/kaffeine.git/log/ https://quickgit.kde.org/?p=kaffeine.git and run Kaffeine with the new --debug option? I'd like the logs when running with it. It should show the transponders it found, plus the scan info. It also helps if you could record 30 seconds of the content of the initial transponder (the one at the scanflie.dvb) using -P option. Something like: dvbv5-zap -r -P -t 30 -c /devel/v4l/dtv-scan-tables/dvb-c/de-Berlin 39400 With that, I can use the file to simulate using a DVB-C signal generator. Tthe above assumes that you have a copy of the dtv-scan-tables stored on your home directory, and you're using the de-Berlin file. You can download the more updated scantable from: https://linuxtv.org/downloads/dtv-scan-tables/dtv-scan-tables-LATEST.tar.bz2 PS.: It is likely that the file will be bigger than the maximum size that bugs.kde.org accepts. So, the best is if you could place it somewhere and send me a download link directly via e-mail. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=364298 --- Comment #3 from lev.co...@gmail.com --- It's DVB-C. Scanfile entry: C 41000 690 NONE QAM64 The following tests were done with kaffeine 2.0.3 and kaffeine was restarted every time after resetting the tuner timeout values. Changing the tuner timeout from 1500ms to the maximum of 5000ms didn't yield any different results, even lowering the tuner timeout to 500ms didn't make any difference: 500ms: 126 Channels 1500ms: 126 Channels 3000ms: 126 Channels 5000ms: 126 Channels I attached the logs during the scan and a dvb dump. -- You are receiving this mail because: You are watching all bug changes.

Actually, after double-checking the code, the only timeout passed through the libdvbv5 is the scan transponder timeout, with Kaffeine currently doesn't use. So, changing the timeout should work fine. Please try increasing it for us to see what's going wrong. Are you having problems with DVB-C, DVB-T/T2 or DVB-S/S2? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=364298 --- Comment #1 from Mauro Carvalho Chehab --- Could you provide some additional data? What's the transponder you're trying to tune? Please also post the debug logs with both 1.3.1 and 2.0.x. So far, I suspect that this could be a timeout issue, but it is hard to know without having more data and doing some tests. There is a per-device parameter that controls the tuner timeout. You could try to increase it, and see if the number of discovered channel changes. That's said, this parameter is not propagated to libdvbv5. It means that, if the issue is related to the needed time to lock into a frequency, just changing it won't fix, but if the issue is related to the time Kaffeine takes to get the needed MPEG-TS data, it may solve your issue. I'll take a better look on how to better pass the tuning timeout to libdvbv5. -- You are receiving this mail because: You are watching all bug changes.
