| [01:18:51] | gigem: | stuarta: I know that. Maybe there are other places but I know we have our own parsing in two places. One is in the recorders where we count frames and parse the PAT and PMT (I had forgotten about this last part). The other is (was?) our own mpeg2 demuxer (peterbennett might have reduced that to a small patch or even eliminated it altogether in the ffmpeg 3.4 (I think) resync. |

| [09:17:44] | stuartm: | gigem: This would be the backend, the first patches extend and improve the SCTE-35 parsing support. It also makes a small change in the ATSC audio descriptor parsing |
| [09:18:50] | stuartm: | future patches will be adding hooks or logging more detail for transport stream analysis |
| [09:20:36] | stuartm: | actually John has already reviewed the original patches some time back, he's could review the updates |
| [09:23:10] | stuartm: | we actually support quite a lot more than just parsing the PMT and PAT in this code. It's not complete but we optionally support parsing quite a few different tables as well as standard data streams |
| [09:24:52] | stuarta: | what are we trying to achieve? |
| [09:25:56] | stuartm: | I also want to update the quality stuff that Daniel first worked on. At present while we track the discontinuties etc in real time and log issues, we only store that information when the recording ends. This means even if there is a signicant discontinuity in the first few minutes of a recording, we'll only know something is wrong from the recording metadata – 30, 60, 90 minutes later. For something like a film, that's enough to miss the |
| [09:25:57] | stuartm: | opportunity to reschedule and catch a +1 hour repeat. |
| [09:28:07] | stuartm: | stuarta: for those with access to a SCTE-35 data, this information can be used to splice out adverts with frame level accuracy, or set bookmarks at the program start etc. |
| [09:28:45] | stuartm: | The 2019 version of the standard even introduces markers for the start/end of opening and closing credits. |
| [09:29:01] | stuarta: | awesome |
| [09:30:41] | stuartm: | I wouldn't get too excited, SCTE-35 is usually stripped out by broadcasters before transmission to the end user. |
| [09:31:59] | stuartm: | however for the professionals using MythTV, it's very useful. Daniel first started adding SCTE-35 support many years back, but it was incomplete, so I've finished it off and updated it to the very latest standard. |
| [09:32:05] | stuarta: | that was my next question |
| [09:32:16] | stuarta: | do we even see it |
| [09:34:46] | stuartm: | I do also want to make more of the EIT running indicator which we talked about endlessly for a couple of years and then went nowhere (not sure if that's changed) |
| [09:35:17] | stuarta: | iirc there may be some patches in trac |
| [09:41:48] | stuartm: | basically a change in focus at work means I get to spend time working on MythTV, some of this will be for the benefit of pro users, some will be of use to everyone and some will just be for home users (i.e. stuff I'm doing mostly for me) |

| [09:46:54] | stuartm: | web frontend is something that has been eating at me for a long time, it was left in an unfinished state and I want to rewrite the client side elements, introducing better functionality and making the whole thing mobile friendly |
| [09:47:19] | stuarta: | yes that could do with work |
| [09:47:26] | stuarta: | there's stuff i want to get in there as well |
| [09:47:52] | stuarta: | like being able to startup the backend without even having a DB, and do the full setup, including channel scanning via the web interface |
| [09:48:50] | stuartm: | yes, improved setup is a must-have (nothing new there) |
| [09:49:59] | stuartm: | I'd like to get it to the point where the complete setup can be done via the services API. |
| [09:50:24] | stuarta: | yep, then the actual gui part can just make calls to the services api |
| [09:50:30] | stuarta: | very web 2.0 |
| [09:50:51] | stuartm: | also the ability to add/remove capture cards/recorders without restarting the backend – that's high on my list |
| [09:51:55] | stuartm: | although only really possible for IP based inputs, since I'm sure few people will be hotplugging PCI-e cards ;) |
| [09:52:27] | stuarta: | a lot of them these days are just a pci-usb bridge with the usb device on the other side |
| [09:52:39] | stuartm: | yup |
| [09:53:04] | stuarta: | which means you can hotplug them without even opening the case ;-) |
| [09:53:36] | ** stuarta has done this before ** | |

| [17:01:35] | hampton: | markk_: I committed my last batch of initialization/variable name cleanup changes for now. I skipped files where you were doing major surgery, but you'll see a couple of minor conflicts at your next import of master. After you collapse the render branch back into master, I'll make a final pass to see what got missed and still needs to be cleaned up. |
