| [01:32:08] | kukks: | Hi all. What's a nice way to contact the mythtv developers about wanted/missing/useful additions? I'm living in Berlin (Germany) and would like to help implementing the new *special* DVT-T2 HD, which will be the default here in March 2017. |
| [01:46:13] | kukks: | I'm using a "TBS-6205 DVB-T2/T/C Quad TV Tuner PCIe Card" and nearly all is working fine with mythtv. The DVB-T2 multiplex-channel 42 is available here in Berlin since *many* months already – to test the new HEVC-stuff, etc.... I have lots of *nix* programming experience... :-) |
| [01:50:28] | kukks: | atm mythtv is just ignoring that new "german" DVB-T2 HD stuff. BTW – other backends (e.g. tvheadend) are already supporting it. But i would like to stay with mythtv. :-) |

| [15:56:55] | dekarl1 is now known as dekarl | |
| [16:04:01] | dekarl: | kukks, if you read the logs, can you capture PAT/PMT/SDT of the new mux with dvbsnoop (including hexdump)? Basically it should "just work" but I think no one ever tested it, so some simple piping may be missing |
| [16:04:25] | dekarl: | stuarta, did anyone add the new service types? |
| [16:05:18] | stuarta: | dekarl: which types were they? i added some a while ago |
| [16:10:55] | stuartm: | DVB-T2 with AVC works, I'm guessing here that it the HEVC multiplexes are doing something differently - |
| [16:12:52] | stuarta: | i suspect it might be slightly different signalling |
| [16:14:40] | dekarl: | I don't see any mention of HEVC |
| [16:15:36] | dekarl: | I'm not finding a list |
| [16:16:21] | stuarta: | dekarl: can you see if you can find anything where someone has captured the signalling? |
| [16:16:57] | stuartm: | right, I'd expect some changes to increase bandwidth at the expense of range – higher symbol rate, different modulation maybe |
| [16:17:23] | stuarta: | i'm thinking along the lines of the video pid's aren't properly identified or the like |
| [16:18:10] | stuartm: | actually, ignore all that, reading something which indicates that they went with HEVC to support more HD channels and not higher resolutions |
| [16:18:17] | stuartm: | I see HEVC and tend to assume 4k |
| [16:18:47] | dekarl: | I think it may be as simple as new values for service_type that we need to handle in IsDTV() |
| [16:18:59] | dekarl: | hence me asking for a dump of the actual PMT :) |
| [16:20:26] | stuartm: | wow, 11 HD channels on a DVB-T2 multiplex ... to me, that suggest they are shoe-horning them in at the expense of encoding quality |
| [16:21:29] | stuartm: | https://www.thebroadcastbridge.com/content/en . . . ng-available |
| [16:22:03] | stuarta: | dekarl: yeah, that's exactly what i was thinking |
| [16:25:25] | dekarl: | around here https://github.com/MythTV/mythtv/blob/master/ . . . tors.h#L1487 |
| [16:26:00] | MitchCapper: | dmfrey not sure if you are submitting that log to try and troubleshoot your video encoding issue (if so will probably need more of the log as I only see audio references so far) or the interlace issue, in which case can you confirm thats an interlaced MKV? |
| [16:26:15] | stuarta: | dekarl: bit further down in the IsHDTV() section |
| [16:26:27] | stuarta: | or even isUHDTV() |
| [16:26:30] | dekarl: | http://www.etsi.org/deliver/etsi_en/300400_30 . . . v011501p.pdf – Annex I |
| [16:27:37] | dekarl: | page 77 / table 87 – 0x1F – HEVC digital television service |
| [16:28:40] | stuarta: | that's covered by IsUHDTV |
| [16:29:02] | stuarta: | so I wonder if he's running 0.27 and not 0.28 |
| [16:29:05] | dekarl: | details about resolution / mono or stereoscopic is in the component descriptor |
| [16:29:21] | stuartm: | yeah |
| [16:29:59] | dekarl: | so we're back to square one. see a specimen and write some tests ;) |
| [16:30:28] | stuarta: | tests?!?!? what are these test things you speak of???? ;-p |
| [16:30:45] | stuartm: | anyone know what NVOD means in this context? We're skipping those types currently |
| [16:31:05] | stuarta: | N... Video On Demand? |
| [16:31:55] | dekarl: | stuarta, that's these mean critters that always spoil the surprise on production day |
| [16:32:25] | stuarta: | heh, the problem i have with TDD is not enough people write tests that should fail |
| [16:32:41] | stuarta: | ie. the write a test, make the test pass, then :shipit: |
| [16:33:01] | stuarta: | but no tests with bad data, strange input etc etc |
| [16:33:02] | stuartm: | could be, as in the old Sky style 'VOD' which wasn't on-demand at all, they simply had showings at 30–60m intervals and you had to wait until the next showing started |
| [16:33:30] | stuarta: | maybe the N stands for Not quite, or Nearly |
| [16:34:16] | dekarl: | stuartm, IIRC NVOD is the broadcast solution for pay-per-view with the movie starting every 30 minutes or so on half a dozen channels |
| [16:34:32] | stuartm: | tests that should fail are harder, you have to write code which generates random input and if the input is random every run the test would be subtly different |
| [16:34:35] | stuarta: | that's the old sky style |
| [16:34:50] | stuartm: | dekarl: yeah, that's what we're talking about |
| [16:34:55] | stuartm: | but thanks for confirming |
| [16:35:37] | dekarl: | good thing is, HbbTV is coming to UK and US, so we can have HTML5 + MPEG2-TS over HTTP for VoD |
| [16:36:08] | stuartm: | that's often the problem I have with unit tests, writing tests as the author of the code doesn't test my assumptions, it reinforces my mistakes |
| [16:36:14] | stuarta: | i saw something like that in the wild here briefly, but then it got shutdown |
| [16:36:40] | stuartm: | unit tests should be written by someone who didn't write or hasn't seen the code, based on the requirements and expectations |
| [16:37:10] | stuarta: | dekarl: it signalled an iptv endpoint via the mheg program |
| [16:37:21] | stuarta: | stuartm: exactly |
| [16:38:01] | dekarl: | stuarta, that's the established aka soon old way ;) |
| [16:38:30] | stuarta: | mythtv kinda worked with that |
| [16:38:45] | dekarl: | yes, we have zero HbbTV support :/ |
| [16:38:59] | stuarta: | it happily recorded the mheg, so when you watched the program back you received the currently showing program, rather than your recorded one ;-) |
| [16:39:41] | dekarl: | Kudos to everyone who adds the mixing of DVB EIT/MHEG script + IPTV video/audio into a recorder |
| [16:40:01] | stuarta: | i wish i had the required skill level |
| [16:40:11] | dekarl: | recording either works like a charm |
| [16:40:20] | dekarl: | got to run, see you later |
| [16:40:25] | stuarta: | later |
| [16:46:04] | stuartm: | If anyone does it, I'd lay money on it being either Dave Matthews or LVR |
| [16:52:48] | stuarta: | dave matthews would be the one i'd have reached out to |
| [17:00:15] | stuarta: | i've been having far more fun exploring SSO for when I get around to upgrading the various other bits of our infrastructure |
| [17:00:26] | stuarta: | it's working pretty well actually |
| [17:02:31] | stuarta: | now i just need to work on protecting wiki, forum & trac, whilst upgrading them to latest |
| [17:06:57] | stuarta: | right, i'm done for the day. |
