| [09:31:05] | stuarta: | i probably can, wtf we looking for? |
| [09:35:13] | stuarta: | dekarl: you can see roger's musing on mythtv-dev list |
| [09:44:45] | enyc: | stuarta: "< dekarl> enyc: a good start would be NIT/BAT/PAT/PMT/SDT/AIT from one of the new DVB-T2 HD muxes. hexdump + decode would be nice. http://dvbsnoop.sourceforge.net/examples/example-sdt.html just ./dvbsnoop -n 1 <PID of the table> without -nph (without no hexdump)" |
| [10:06:27] | stuarta: | right, it's worth reading roger's emails to the dev list, it explains somewhat what he's trying to do with those temporary ids |

| [15:56:21] | dekarl: | enyc, doh I was confusing the new german DVB-T2 and the good ole DVB-T2 in the UK :/ |
| [15:56:50] | dekarl: | still, the same tables are interesting for channel scanning purposes |
| [15:57:18] | dekarl: | e.g. the AIT would help us to see MHEG5 vs HbbTV test broadcasts etc |
| [15:57:53] | dekarl: | stuarta, I have getting back to roger's other questions on "the list"... e.g. "what's the real primary key in DVB land" kind of questions... |
| [15:58:15] | enyc: | dekarl: hrrm.. I'm wondering what information site to lookup info on UK/Oxford transmitter well anyway.... |
| [15:58:22] | stuarta: | my babelfish was struggling with his questions.... |
| [15:58:31] | dekarl: | dman, missed a bunch of servers with 144GiB memory each for 300 EUR + change :/ |
| [15:58:33] | enyc: | dekarl: last i checked there was only one dvb-t2 mux, but maybe there is more than one now |
| [15:59:17] | dekarl: | dvbtmap.eu? I sent them the pointers to the official frequency authorities, so they should cover europe |
| [16:14:37] | enyc: | hrrm not being helpfl with info there... ukfree.tv suggests actually 3 dvb-t2 muxes now |
| [16:14:45] | ** enyc checks mythtv-setup etc... ** | |
| [16:29:16] | stuarta: | enyc: there's only 1 dvb-t2 mux on crystal palace |
| [16:32:41] | enyc: | stuarta: but oxford... has this com7 com8 as well? |
| [16:33:37] | enyc: | stuarta: https://ukfree.tv/transmitters/tv/Crystal_Palace claims com7 com8 are DTG-6 which they define as DVB-2 |
| [16:34:35] | stuarta: | been a while since i rescanned dvb-t2 |
| [16:36:52] | enyc: | my mithtv-setup was misbehaving i will have to go down re-poke it later =) |
| [16:37:03] | enyc: | stuarta: do so first if you can and let me know what you discover! |

| [21:35:04] | stuarta: | "should be" any early testers are welcome |
| [21:35:17] | stuarta: | i run it, but only on my dev box, not my prod one |

| [21:52:21] | stuarta: | Roklobster: so it work's just fine for you with that patch? |

| [22:29:22] | enyc: | I don't see anything in https://www.mythtv.org/wiki/Release_Notes_-_29.0 to give me a clue ;p |
| [22:29:57] | enyc: | clue what 0.29 will do, other than be newer ffmpeg and presumably somewhat-newer-codecs and usable native webfrontend maybe |
| [22:30:30] | dekarl: | its going to be great and getting rid of some old baggage we carry along for to long |
| [22:30:56] | dekarl: | oh, and its going to be released quicker (that was the plan at least) |
| [22:31:19] | enyc: | whats' happening about ffmpeg 'delta' ? — is that managing ot get 'smaller' ? |
| [22:31:43] | dekarl: | I think jya can answer that best |
| [22:32:16] | dekarl: | I think the closest thing to a plan is https://code.mythtv.org/trac/query?group=stat . . . lestone=29.0 |
| [22:32:35] | enyc: | thankyou |
| [22:33:06] | enyc: | stuarta: did you manage to rescan in crystal palace and actually get 3 dvb-t2 muxes over there ?? |
| [22:35:09] | enyc: | dekarl: equally i wonder what the 'trigger' is for classing 0.28 a new point-release 0.28.1 ... major bugs fixed?? |
| [22:36:37] | dekarl: | personally I think a good trigger would be "someone willing to get a .1 release backported into Ubuntu LTS and following" as the problem reports due to the last minute mysql changes are wasting everyones time |
| [22:38:03] | jya: | enyc: what's that about? |
| [22:38:04] | enyc: | if you can get something resembling a debian copyright file and manpage/whatever for any 'undocumented commands' wookey may well be able to sponsor into debian soon at least.... but I don't know about ubuntu world |
| [22:38:43] | enyc: | jya: i was just wonedring what the size of ffmpeg delta / relationship with upstream is lke these days... managing to need 'less' changes from upstream ? |
| [22:39:06] | jya: | I can tell you the size of the diff :) |
| [22:39:32] | enyc: | jya: are upstream being 'better' so need less diff than used to have ;p |
| [22:40:23] | jya: | the changes have now been almost fully separated ; also in the previous 3.0 release, most of the ffmpeg code we used to rely on and always gave us grief because of conflicting changes got removed entirely from FFmpeg |
| [22:40:34] | jya: | the code had been deprecated for a while |
| [22:40:53] | jya: | so I had to resurrect the code, and place that in our own unique source |
| [22:40:57] | enyc: | thats helpful especially for applying upstream security updates... |
| [22:41:16] | jya: | the good news with that is that it now makes resync much easier, as there's almost nothing left to conflict |
| [22:41:35] | jya: | the major differences with upstream are: |
| [22:41:46] | jya: | 1- unique mpegts demuxer |
| [22:42:09] | jya: | 2- callbacks to handle change of resolution / content |
| [22:42:43] | jya: | 3- extra parameters to internal function to handle some flags like having audio / having video and having dual language |
| [22:42:54] | jya: | 3) is what's causing the most pain to maintain |
| [22:43:17] | enyc: | and you wonder how much of this upstream might accept as a patch these days?? not interested? |
| [22:43:19] | jya: | the reason for 1, is that we support additional subtitles handling |
| [22:43:45] | jya: | the only thing worth submitting would be the subtitle handling |
| [22:43:56] | jya: | everything else we've sneezed on that code, is more akin to hacks to me |
| [22:44:20] | jya: | the callbacks are awful, they aren't thread-safe, and we could do without |
| [22:44:31] | jya: | but not without a big rewrite of avformatdecoder |
| [22:44:35] | enyc: | ;p |
| [22:45:17] | jya: | problem with the subtitle thing, is that the demuxer API has so changed over the years, none of the code we have is directly applicable to the ffmpeg mpegts demuxer |

| [23:08:13] | sphery: | Roklobster: The patch hasn't been applied, yet. It may well be that your database configuration now how a SQL mode that's compatible with MythTV's SQL usage (i.e. not one of the strict modes). |
| [23:09:08] | sphery: | Ideally that patch would be applied, but I don't have a working dev system, so I won't be able to get it committed for a while. I was hoping someone else might do it in the meantime. |
| [23:09:33] | Roklobster: | sphery: i didn't make any changes to myysql |

| [23:10:02] | Roklobster: | it's mythbuntu 16.04 so maybe |
| [23:10:03] | sphery: | or even an upgrade of MySQL--they seem to be doing a lot of changes to their default SQL mode, lately |
| [23:10:20] | Roklobster: | RIP mythbuntu |
| [23:11:12] | sphery: | btw, nice to meet you (by your other name). I didn't realize that you were the reporter on the ticket. |
| [23:11:28] | Roklobster: | hi yes no worries |
| [23:11:40] | sphery: | anyway, glad it's working for you, and I hope to get that patch in before long |
| [23:12:21] | Roklobster: | yeah the opimisations dekarl (or you?) put into it a while back do speed up mythtv |
| [23:12:54] | Roklobster: | jya: do you think you'll ever do some deint work for VAAPI? |
| [23:16:01] | jya: | Roklobster: I was talking about that 2 days ago.. I may see about working on some filters with the new VAAPI APIs |
| [23:16:11] | jya: | they have a few options for deinterlacing |
| [23:18:30] | Roklobster: | ah great – i have been running with intel 510 for a while now. mp2/264/265 work great with it. quite a few dvb-t channels now don't seem to need deint presumable because they are HD or on h.264 The lack of deint isnt too noticable though – just small text like in the bloody funeral insurance ads |
| [23:18:59] | jya: | well, there's is deinterlacing available, only bob, but better than nothing |
| [23:19:25] | Roklobster: | hmmm, i have set it but doesn't seem to work the missng lines are noticable. not a drama. |
| [23:19:34] | Roklobster: | unless that is how bob is |
| [23:20:04] | Roklobster: | deint on my old gt210 card worked well. |
| [23:20:10] | Roklobster: | but it's 7 years old and going to the tip |
| [23:20:54] | Roklobster: | i am happy to test out the filters and i keep the vaapi repos up to date |
