| [01:30:43] | markspieth2: | gigem: building libs again with fresh checkout. let you know in 45min |
| [01:34:51] | markspieth2: | failed for me too. will fix. |
| [01:38:34] | gigem: | markspieth2: K. I just got home and was about to try again myself. |
| [01:56:56] | markspieth2: | maybe remove sysroot conf option from fontconfig build. |
| [01:57:27] | markspieth2: | if this one builds I'll push the oneliner |
| [02:02:30] | markspieth2: | pushed update |

| [02:28:44] | markspieth2: | I also noticed on a low res channel hw kernel deint does a terrible job. looks like it samples with an offset in x making edges look terrible. |
| [02:29:11] | markspieth2: | this is with mediacodec decoder. |
| [02:45:43] | gigem: | Still building. |
| [02:46:02] | gigem: | For standard definition, you should probably use yadif 2x. |
| [02:53:59] | markspieth2: | he linear works ok |
| [02:54:10] | markspieth2: | hw |
| [02:56:01] | markspieth2: | still building is a good sign |
| [02:57:20] | gigem: | libass and its prereqs built by themselves so I expect that to work. Just gotta wait a little longer. I think it's in webkit now. |
| [02:57:56] | gigem: | mark____: See deinterlacer talk above. |
| [03:41:18] | gigem: | Subtitles. And there was much rejoicing! Thanks, markspieth2. Now I can go back to figuring what and how I want to transcode. |

| [14:12:17] | markspieth: | Another observation in master android with mediacodec. When using speedup and interlaced content, the program duration counter counts faster than real time and then reaches 0 and forces play rate back to 1. I suspect this is related to rate doubling. 35min progam at 1.55 reaches this state at around 24 min. |
| [14:14:04] | markspieth: | Also with faster playback rate with mediacodec, frame judder/drop is annoying. When I switched to GL High Q profile (no mods), S/W decoding playback at this rate is perfect. AVSync2 was used. |
| [14:36:50] | peterbennett: | markspieth: Some work needs to be done on duration counting, i agree. |
| [14:37:55] | peterbennett: | markspieth: I think both of these problems are related to the fact that speedup norlayy disabled frame doubling, but with mediacodec on sheld it cannot disable teh frame doubling |

| [17:26:29] | mark____: | peterbennett: why would using mediacodec for decoding have any influence on doublerate? |
| [17:59:18] | peterbennett: | mark____: Mediacodec on shield deinterlaces in the decoder, we have no way of turning off the deinterlace |
| [18:01:19] | peterbennett: | mark____: So it is always coming from the decoder at double rate if it was interlaced |

| [20:19:39] | mark____: | markspieth: the android builds on your website – should they work on the shield? Have started playing with the android stuff but I only get the splash screen before it bails out. latest build. |
| [20:24:35] | peterbennett: | mark____: I have a site with android build that work |
| [20:29:24] | mark____: | peterbennett: do you have a link? |
| [20:29:35] | peterbennett: | Is is in the wiki |
| [20:30:57] | peterbennett: | https://dl.bintray.com/bennettpeter/generic/ |
| [20:31:08] | peterbennett: | The 64 bit version works on shield |
| [20:31:34] | peterbennett: | wiki page describes how to install it etc -> https://www.mythtv.org/wiki/Android |
| [20:32:17] | peterbennett: | I have not yet put the official mythtv30 version there |
| [20:33:01] | peterbennett: | But those that are there work fine |
| [20:36:12] | markspieth2: | mark____: yes they work for me onte shield. they have my extra patches though. some 4k experimental stuff and other things |
| [20:37:30] | peterbennett: | markspieth2: is the libass stuff now ok on android and is it committed to master and v30 ? |
| [20:38:08] | peterbennett: | markspieth2: I am waiting for that to be sorted out before I make a build for the bintray website |
| [20:41:36] | markspieth2: | yes.however gigem said it didn't work for everything. I suspect it's a fontconfig config issue. I tried it with dvbt subtitles and it works. |
| [20:43:48] | markspieth2: | I suspect font type is the issue an if it can't find one suitable it shows nothing |
| [20:59:33] | mark____: | markspieth2, peterbennett: wow – fantastic work! looking really good |
| [21:01:14] | gigem: | peterbennett: atsc cc and vbi cc work. Normal a/v subtitles don't, at least for me. Like markspieth2, I suspect a font problem. I'm trying to narrow it down. |
| [21:13:43] | mark____: | markspieth2, peterbennett: is there anyway to do display refresh rate switching on android tv? |
| [21:22:10] | gigem: | mark____: I believe Kodi can do it, so in theory, we could too. I doubt it's implemented, though. |
| [21:26:05] | mark____: | gigem: found it: https://github.com/xbmc/xbmc/blob/master/xbmc . . . /XBMCApp.cpp |

| [21:55:47] | peterbennett: | mark____: We still do not know how to get the display to support 4k screen size on android, it seems stuck on 1920x1080 |
| [21:56:28] | mark____: | peterbennett: I think we need to disallow all deinterlacers on android. does that sound correct? |
| [21:56:52] | mark____: | peterbennett: get Qt to support 4k? |
| [21:57:06] | peterbennett: | mark____: On shield it does not matter what you set, because MythTV always sees progressive. |
| [21:57:14] | mark____: | deinterlacers with mediacodec |
| [21:57:39] | peterbennett: | mark____: On other android devices there is no deinterlace and we need to use the OpenGL deint. |
| [21:58:03] | mark____: | well that's annoying:) |
| [21:58:10] | mark____: | anyway we can test for it? |
| [21:58:34] | peterbennett: | mark____: On fire TV 4K, mediacodec crashes if it sees interlaced content while decoding |
| [21:59:46] | peterbennett: | mark____: On fire TV (non-4k) mediacodec presents everything as if it was progressive even if interlaced. So the OpenGL interlacers do not deinterlace it. |
| [22:00:39] | peterbennett: | Bottom line: I set all mpeg2 to be software decoded so the OpenGL deintelace works. |
| [22:03:11] | peterbennett: | mark____: Re 4K – the physical screen is 4k and running at 4k but something is scaling what the app does so that the app thinks it is 1080. |
| [22:05:05] | peterbennett: | People who have interlaced h264 will have to do something also when using fire tv . I do not have interlaced h264. |
| [22:11:23] | mark____: | peterbennett: on my oneplus 1 (4+ year old android phone) everything is working nicely. needs a keyboard to be really functional though:( |
| [22:12:11] | mark____: | I can't remember now whether it was on the phone or shield now – but there was one clip that was definitely being deinterlaced twice. turned off gl deinterlacer and it was smooth. |
| [22:12:58] | mark____: | peterbennett: there must be a way to query what the device supports |
| [22:14:08] | peterbennett: | mark____: I think the deinterlace capabilities are being hidden by FFmpeg |
| [22:14:53] | peterbennett: | So it seems like you have the opposite – android was deinterlacing but telling Mythtv that it was still interlaced. |
| [22:15:21] | mark____: | peterbennett: re ffmpeg – yes, maybe – but there is nothing stopping us from checking once at startup |
| [22:15:39] | mark____: | yes- i need to confirm – but it definitely seemed to be deinterlaced twice |
| [22:15:47] | peterbennett: | I tried it on my phone and it played ok but I don't think I could tell whether it was deinterlaced or not – that would require very powerful eyes |
| [22:17:37] | mark____: | peterbennett: https://appbus.wordpress.com/2016/04/12/resol . . . id-ios-bb10/ |
| [22:17:41] | peterbennett: | On the phone I used the network remote interface to control it since I cannot connect a keyboard to my phone. |
| [22:19:36] | peterbennett: | The 4K is somewhat academic right now, as I believe we need direct gpu to screen video to support it. |
