| [03:56:44] | dragonia_: | i don't love handbrake for transcode either.. it "tries to be smart" and messes with too many things |
| [03:57:09] | dragonia_: | i prefer straight ffmpeg w/ h265 |
| [03:57:44] | dragonia_: | speaking of h265.. what was the reason that vdpau is now not supporting h265? |

| [05:15:37] | gigem: | I'm using HandBrakeCLI and only diverging from defaults when needed. It's somewhat tedious but not near as tedious as using ffmpeg directly. |
| [05:18:35] | dragonia_: | i have a script preconfigured, so it's pretty fire and forget.. but i'm really only taking a 1080p bluray, transocding the video, copy the audio, and subtiles |
| [05:42:49] | gigem: | My case is complicated by the fact that I want to preserve the primary language and secondary language closed captions. Neither ffmpeg nor handbrake can do that correctly with my recordings. |

| [13:02:31] | stuarta: | peterbennett: looks like the only way forward on the rpi is to use libcec4-dev, which is different to every other debian based distro |
| [13:06:46] | peterbennett: | stuarta: can you give alternatives, like libcec|libcec4 with ansible? |

| [16:35:28] | ** peterbennett will be upgrading MythTV master to FFmpeg 4.1 ** | |
| [16:37:43] | markk_: | peterbennett: did FFmpeg reinstate VDPAU HEVC? |
| [16:39:05] | peterbennett: | markk_: AFAIK HEVC never worked with VDPAU. |
| [16:46:27] | markk_: | peterbennett: https://www.phoronix.com/scan.php?page=news_i . . . bles-HEVC-NV |
| [16:49:54] | peterbennett: | markk_: I guess it must be true then. I can give it a try, it says it needs driver version 410. Currently I am on 396 which is the lowest level for NVDEC |
| [16:50:37] | markk_: | I'm on 340 :( |
| [16:52:46] | stuarta: | the release mad phoronix at least |
| [16:52:48] | peterbennett: | ppa:graphics-drivers/ppa has the later ones for Ubuntu, |
| [16:53:12] | stuarta: | and if you are on fedora, i recommend the negativo repositories |
| [16:54:21] | kwizart: | stuarta, why the full hell such scam repo ? |
| [16:55:03] | stuarta: | kwizart: i find it a nice clean packaging of nvidia drivers |
| [16:55:09] | peterbennett: | I guess I need a wiki page to explain that you need at least 396 for NVDEC |
| [16:55:26] | stuarta: | peterbennett: do we have a top level NVDEC page? |
| [16:55:32] | kwizart: | stuarta, this is not the case, they are very bad packaging, and it's only a bad copy of rpmfusion |
| [16:55:49] | kwizart: | there are several terrible miss take in his packaging |
| [16:55:57] | peterbennett: | The latest Nvidia drivers show as open source, they used to say proprietary |
| [16:57:48] | stuarta: | kwizart: i like rpmfusion, but for a reason i can no longer remember i got on better with that nvidia packaging |
| [16:58:07] | kwizart: | stuarta, many improvements are designed by RPM Fusion (aka me) |
| [16:58:34] | stuarta: | point taken |
| [16:58:34] | kwizart: | specially the nvidia fallback is an idea from hansg, but implemented by me |
| [16:59:21] | stuarta: | kwizart: well i shall try them again, when i don't have 4000 other things on the urgent todo list :( |
| [17:00:27] | peterbennett: | https://www.geforce.com/drivers |
| [17:00:28] | stuarta: | kwizart: i assume you also do akmods for the kernel modules? |
| [17:01:25] | kwizart: | yep, still few thing to improve in this area, current topic are secureboot and ostree distro support |
| [17:01:41] | stuarta: | ah secureboot, such fun that is |

| [17:18:09] | dragonian: | so i was suprised to see that it was now not supported. |
| [17:18:13] | markk_: | dragonian: it is/was silently disabled for vdau |
| [17:18:36] | markk_: | i.e. it just falls back to ffmpeg decoding |
| [17:19:08] | dragonian: | so i guess thats the 5% that I never checked out the logs |
| [17:19:38] | dragonian: | obviously going forward nvdec is the way to go |
| [17:20:04] | dragonian: | epecially if we can eventually support 4k/10 bit |
| [17:21:20] | dragonian: | if help with nvdec is needed, I'd offer to support. |
| [17:22:00] | dragonian: | I have some experience with ffmpeg from some projects years ago |
| [17:23:11] | dragonian: | I also have a variety of test files and hardware.. 1030, 1050, 1060 with a variety of screens |
| [17:27:22] | dragonian: | i should say ffmpeg/libav development |

| [17:38:04] | dragonian: | thx |
| [17:40:03] | peterbennett: | dragonian: I have added the NVDEC support in master, but it needs the GPU to OpenGL render part to be done still. |
| [17:41:06] | dragonian: | what configuration does it need? |
| [17:42:49] | peterbennett: | Nvidia driver at least 396, Then select playback profile NVDEC |
| [17:43:17] | dragonian: | ok, so just select the profile |
| [17:43:29] | dragonian: | i'll play with it tonight |
| [17:43:50] | peterbennett: | On my system it works with all video except 4K 50fps. It can do 4K 30fps |
| [17:44:27] | peterbennett: | Check the playback data to make sure it is using NVDEC |
| [17:45:08] | peterbennett: | It is still a little rough around the edges, it does play hevc |
