[09:10:03] | markk__: | warpme_: sorry – no joy:( same errors as before (just different build date/time) |
[09:12:36] | stuarta: | markk__: are you happy with the state of PiP for fixes/31? |
[09:12:52] | stuarta: | ie. does it basically function, without any frills? |
[09:13:10] | ** stuarta is pondering if the branch is fit for the release ** | |
[09:19:17] | warpme_: | markk__: ok – then lets do last attempt at this stage: I'll prepare build with changes within dram controller regarding timings (as error Your box is reporting is dram write leveling error). Patch is advised by kodi devs. Will provide it to you soon. |
[09:21:56] | warpme_: | markk__: are PLL and PGSR0 values exactly the same? |
[09:32:39] | warpme_: | markk__: in the meantime: is it possible to get picture of board in your device (ideally: something like https://linux-sunxi.org/File:Tanix_tx6_pcb_top.png) and model/board ver. (like https://linux-sunxi.org/File:Tanix_tx6_pcb_bottom.png). Me and Kodi guys still want to get your board ver. to be supported.... |

[15:39:25] | markk__: | stuarta: I've not pushed any pip changes to the fixes branch. I have a simple patch to fix pip running at different rate to main player that is uncommitted. The bigger problem is the lockup that Klaas is seeing not good (assuming he is seeing the same one as me!) – a fairly fundamental blocker to running 2 different players at the same time if I can't see a way around it. |
[15:39:59] | markk__: | warpme_: sorry – been out. will test in a bit. |
[15:49:56] | warpme_: | markk__: re tx6 – np. do it in good time for you. re: pip – i think idea with pip playing with different(lower) rate is a-must. On weak platforms (i.e. ION) – main picture must be HW decoded as user wants to watch main content with smooth playback. Distorting main playback by launching pip is like tail-wedging-a-dog. When pip is launched – in 95% cases it will be sw decoded. As usually cpu is weak do full fps HD decode |
[15:49:56] | warpme_: | - only decreased fps in pip will be possible. This case imho is valid for all platforms with weak cpu (rpi, ION, arm, etc) – so imho pip should be designed to play nicely in strongly cpu-bond cases.... |
[15:53:29] | warpme_: | i really miss proper playback in use-case when I'm watching recording + livetv in pip because i'm awaiting for delayed livetv program to be finally started to broadcast.... |

[20:40:49] | stuartm: | With current master, in LiveTV the frontend is leaking serious amounts of memory. Particularly on a 'no lock' channel, where it's leaking 1GB a second or more – it gets OOM killed on a 32GB system |
[20:41:56] | stuartm: | Is this a known issue and is anyone looking into it? If not I'll start valgrinding |
[20:42:10] | stuarta: | stuartm: not heard of it, and welcome back! |
[20:42:22] | stuarta: | long time no see! |
[20:43:58] | stuartm: | thanks, just found a moment this weekend to get my myth system back up and running, but I've run into a lot of issues :( |
[20:44:08] | stuartm: | stuarta: how are things? |
[20:44:54] | stuartm: | not yet sure if the leak is related to the tens of thousands of lines being written into the the frontend logs: |
[20:44:56] | stuarta: | not too bad, lots to do, keeping plenty busy. you? |
[20:45:05] | stuartm: | 2020-03–10 20:37:50.367185 E PulseAudio: WriteAudio, short write, 0 of 2822 |
[20:45:07] | stuartm: | 2020-03–10 20:37:50.367186 E PulseAudio: WriteAudio, stream write failed: PA_ERR_INVALID |

[20:45:36] | stuartm: | stuarta: too busy, unfortunately. Don't have time to catch my breath. |
[20:45:38] | gigem: | stuartm: Hey! I've not seen that issue either. My mom uses live TV a lot on a shield. If was working that badly, I'd have heard about it. |
[20:45:58] | stuarta: | pulse audio certainly isn't something i've used for a long time |
[20:47:55] | stuartm: | gigem: very likely configuration dependent, but since I'm having signal issues right now that's exposing a few problems. For example the notification popups telling you there's no lock are on top of the screen stack so they are hiding the OSD menu and the whole screen, making changing channel really challenging. |
[20:48:36] | stuarta: | ouch |
[20:49:01] | stuarta: | they used to disappear |
[20:49:03] | stuartm: | stuarta: that was the case for me for a long time, and certainly on a dedicated frontend I wouldn't bother, but I'm testing this on my desktop right now and there I've come to need pulse for moving audio from different apps to different outputs etc |
[20:49:20] | stuarta: | fair enough |
[20:49:45] | stuarta: | i say that, however i find pulseaudio is running on this laptop ;-) |
[20:50:21] | stuartm: | stuarta: they do disappear, eventually, after 10–20 seconds which is too long a timeout. Honestly that's the least of my worries at the moment, and one I can easily fix. |
[20:50:30] | stuartm: | let's see what valgrind says about this leak |
[20:51:37] | stuartm: | as leaks go, it's the most impressive one I've seen in a very long time |
[20:52:51] | stuarta: | certainly |
[20:56:43] | ** stuarta continues bashing on rails version of smolt backend ** | |
[20:57:41] | stuartm: | some things never change |
[20:59:24] | stuarta: | hehe |
[20:59:43] | stuarta: | it's one of the last pretty nasty legacy things left |
[20:59:51] | stuarta: | that and theme packaging :) |
[21:01:13] | stuartm: | I still need to edit the config so I stop getting emails from denyhosts and rkhunter running on the server |
[21:01:50] | stuarta: | i can sort that out |
[21:02:08] | stuarta: | just editing won't help, it'll get blown away by the next ansible run i do |
[21:04:32] | stuartm: | right, you mentioned that when I dropped in here sometime last year, that's why I never did get it sorted. I never made the effort to find/edit whether that ansible deployed config lies |
[21:04:57] | stuarta: | hah, i have a tendacy to lose what i'd planned todo |
[21:06:22] | stuartm: | well I think I see the problem ... it's not a leak exactly, rather it's that the PulseAudio code prints so many errors to the logs, that the logger just falls ever further behind in flushing them to stdout/disk |
[21:06:31] | stuarta: | hmmm |
[21:06:48] | stuarta: | ah, i think you get the ones from alcor |
[21:07:58] | stuarta: | stuartm: fixed, but left you on the foundation email alias |
[21:08:01] | stuartm: | the memory growth that occurs is just the result of millions of LoggingItem instances still in memory |
[21:08:08] | stuartm: | stuarta: thanks |
[21:09:07] | stuarta: | np |
[21:11:48] | stuartm: | yeah, there's no limits placed on the logging queue, and no duplicate message handling. The simplest fix would just be to disable that particular piece of logging in the pulse audio code and brush the logger flaws under the carpet for someone else to deal with later :) |
[21:12:12] | stuarta: | :ship_it: |
[21:12:39] | stuartm: | However I will see if I can fix the logger properly at the weekend |
[21:14:41] | stuartm: | maybe I'll even go as far as figuring out why the pulseaudio write issue exists and fix that |
[21:15:05] | ** stuarta chuckles ** | |
[21:15:11] | stuartm: | it's a rabbit hole |
[21:15:19] | stuarta: | there are many |
[21:18:21] | stuarta: | todo_list.push_front(move mizar to osuosl openstack cluster) |
[21:20:16] | stuartm: | oh, the PA issue might be easy, there's a helpful comment in there saying the code was written against an older version of the API and needs revisiting – that was 10 years ago, so safe to say the whole thing might just be a case of MythTV doing the wrong thing with the present day API |
[21:20:48] | stuartm: | stuarta: Alcor and Mizar are still around? |
[21:21:04] | stuarta: | everything apart from themes is on mizar |
[21:21:12] | stuarta: | themes is still on alcor |
[21:21:17] | stuarta: | which is just about hanging on |
[21:21:35] | stuartm: | and I thought the lab at work was packed full of outdated servers |
[21:21:35] | stuarta: | but i've just found out the cluster hosting mizar is now deprecated |
[21:22:03] | stuarta: | sigh |
[21:23:57] | stuarta: | anyhow, planning these migrations is something that can wait until tomorrow |
[21:27:17] | stuartm: | finally pushed through the bureaucracy to get a single Epyc Rome based system in for evaluation at work, typically upper management have been on at us to reduce hardware costs but they wouldn't grant the budget to evaluate cheaper and potentially better performing platforms |
[21:27:37] | stuarta: | always the way |
[21:27:58] | ** stuarta heads to bed ** | |
[21:28:37] | stuartm: | all of which is not in my job description, but I got tired of seeing it going nowhere |
