| xfxf | av_wellington_1: still flickering? | 00:03 |
|---|---|---|
| xfxf | av_boardwalk: explain again please, don't understand | 00:03 |
| av_wellington_1 | no | 00:03 |
| xfxf | great | 00:03 |
| av_plenary | xfxf: Alan says that the black magic card needs to be adjusted to keep the levels reasonable both in the room and on the stream and recording. | 00:06 |
| av_boardwalk | all ok fixed by Westpoint staff | 00:07 |
| xfxf | ah, didn't realise the Blackmagic card had those options | 00:07 |
| xfxf | tumbleweed: can you investigate if the gstreamer component has options for volume? | 00:07 |
| xfxf | dont change it live, change during break | 00:08 |
| tumbleweed | I don't see any such options | 00:08 |
| xfxf | send my thx to Alan. haven't needed to adjust before (usually digital sources don't have a volume option) but if the hardware/driver is capable then makes sense | 00:08 |
| tumbleweed | but there will be volume controls on the camera | 00:09 |
| xfxf | yeah, that is maxed | 00:09 |
| tumbleweed | then the best thing you can do is something in the gstreamer pipeline | 00:09 |
| tumbleweed | compression or something | 00:09 |
| tumbleweed | I think CarlFK does compression during encoding? | 00:09 |
| xfxf | would prefer not doing that, don't want to raise the noise floor | 00:09 |
| xfxf | yeah he does very light normalisation of audio | 00:10 |
| xfxf | I keep meaning to fiddle with the melt options to improve it | 00:10 |
| xfxf | boosting it in prod or in the pipeline will increase the background noise floor tho, which isn't ideal | 00:10 |
| xfxf | how is the sound on the stream? | 00:10 |
| xfxf | if clear and loud enough it's probably good enough | 00:11 |
| tumbleweed | it was fine earlier | 00:11 |
| av_plenary | The young AV guy just ran up to say it was clipping on the stream. I don't know why he knew and nobody else apparently did. | 00:11 |
| tumbleweed | he listens to the stream :) | 00:11 |
| xfxf | ok, clipping is bad, should fix | 00:11 |
| xfxf | prefer low volume to clipping | 00:11 |
| av_plenary | It is fixed, Alan reduced the input levels a bit. | 00:12 |

| xfxf | all rooms: we're noticing a/v sync is WAY off in a bunch of rooms. are you guys noticing this? wearing headphones + watching screens I hope? | 00:24 |
| xfxf | wellington1, boardwalk for sure, checking others | 00:24 |
| av_tasman_a | Tasman A doesn't seem to have a problem | 00:24 |
| xfxf | this is not someting easily fixed in prod (i.e. it won't be) so this is important | 00:24 |
| av_boardwalk | look ok to me | 00:24 |
| av_wellington_1 | looks ok for me | 00:25 |
| xfxf | ok, to me, it looks like audio is about 0.5 sec behind video | 00:25 |
| av_tasman_a | please specify which rooms have problems | 00:26 |
| xfxf | maybe specific to sreaming | 00:26 |
| xfxf | i can't tell easily because you guys are mostly on slides | 00:26 |
| xfxf | i'll come to rooms to check | 00:26 |
| xfxf | checked all rooms - sync seems fine. think it is specific to streaming only. sorry for false alarm! | 00:34 |
| av_tasman_bc | mithro, tasman bc has graphical issues | 00:36 |
| av_tasman_bc | xfxf, ^ | 00:37 |
| xfxf | heading there now | 00:37 |
| mithro | I'm in av_tasman_bc right now - not seeing any issues? | 00:40 |
| av_tasman_bc | mithro, xfxf fixed it | 00:41 |
| av_tasman_bc | input1 on etc | 00:41 |
| xfxf | mithro: had to do 'input1 on' again, WER issues before that. thinkpad with mDP dongle | 00:41 |
| av_boardwalk | getting white noise in Boardwalk, not sure why | 00:57 |
| jea | av_wellington_2: would you be able to reframe your camera a bit. i suggest showing the linux.conf.au sign at the bottom, so we have less 'blank' space at the top of the screen | 00:58 |
| jea | thanks :) | 00:58 |
| av_tasman_bc | jea, is our room more quiet than other rooms? | 00:59 |
| jea | av_tasman_bc: it is quieter, but I can hear it alright. happy for it to go up a bit if you can | 00:59 |
| av_tasman_bc | We're pretty high up out of the sound board, and the gain on the yamaha is almost at max | 01:00 |
| av_tasman_bc | jea, ^ | 01:00 |
| av_tasman_bc | xfxf, mithro: is the screen shudder race cond being worked now, or later? | 01:03 |
| mithro | shudder? you mean the single frame flicker or? | 01:04 |
| av_tasman_bc | yes | 01:04 |
| av_tasman_bc | That's a race cond, yeah? | 01:04 |
| av_plenary | We've been getting some... something... in the projector capture in here. | 01:11 |

| xfxf | all rooms: make sure presenters plug their laptops into power. i think what's happening is laptops are going to sleep... and when they wake up they re-activate their displays | 01:19 |
| av_tasman_bc | and the opsis never see a clean disconnect/reconnect or something? | 01:20 |
| av_tasman_bc | opses* (for plural?) | 01:20 |
| jea | yes | 01:20 |
| xfxf | there's a bug with the opsis gateware currently which impacts some laptops - when we run in and type something on the laptop at the front + it then fixes | 01:20 |
| xfxf | laptops on power mean they shouldn't go to sleep or turn off their displays (or at least as quickly...) | 01:21 |
| jea | we are going to add extra signal detection in later (ie. when an EDID is requested, do a reset if needed) | 01:21 |
| xfxf | also, if you didn't see before, make sure people don't put their wireless microphone belt packs in their rear pocket | 01:21 |
| xfxf | people are sitting on the belt packs and damaging the mics... :/ | 01:21 |

| CarlFK | oh hell.... the default is not to replace youtube .... so when we reencode, post_yt skips it and moves onto the next step. | 02:05 |
| CarlFK | adding replace=true to veyepar.cfg on gw1 (where post_yt run ) so that is now the default. | 02:09 |

| CarlFK | I need to restart it so it re-reads the conf file | 02:19 |
| xfxf | also wondering whether the issues you guys have seen in the past with ffmpeg dropping out might be related to rsyncing files during the day - if disk I/o is starved I can see voctocore dropping that sink | 02:19 |

| xfxf | lunch* | 02:33 |
| xfxf | av_plenary: checking | 02:33 |
| xfxf | might be your USB audio interface being stupid (which only affects monitoring) | 02:33 |

| xfxf | tumbleweed: ack, i'm taking the paranoid view, it might be a non-issue, but i'd prefer to avoid doing it until we're 100% sure that's not causing any desync issues | 02:36 |

| av_plenary | kthx | 03:27 |
| xfxf | av_plenary: i'll come next break and listen there | 03:27 |
| av_plenary | It was just one burst of noise for a minute or so, hasn't happened since. Probably just the headphones being funky. | 03:27 |
| xfxf | doesn't sound like a headphone thing | 03:28 |
| xfxf | please note on sheet with approximate time it happened | 03:28 |
| av_plenary | Just figured out I can make something similar happen if I push the wires on the headphones just the right way. | 03:29 |
| xfxf | ah, there you go | 03:30 |

| jea | av_tasman_a: it does get hard. don't move it too much, but if you can see she might go out of frame, pan slowly | 03:33 |

| av_plenary_g1 | keynote presenter apparently is a pacer | 22:13 |
| av_plenary_g1 | i've told him to try and stay near his podium | 22:13 |
| av_plenary_g1 | i'd suggest if he paces, just zoom out so you're framing his entire body on stage | 22:13 |
| av_plenary_g1 | and fill the frame | 22:13 |
| xfxf | guys, zoom out | 22:26 |
| xfxf | chasing the top half of the presenter doesn't look great | 22:26 |
| xfxf | if he's a wanderer, just zoom out so his entire body is in the frame | 22:27 |
| xfxf | his head should be near top, not in the middle | 22:27 |
| av_plenary | We have a plan... cut to wide shot when he heads back to the podium | 22:27 |
| av_plenary | We're just trying to get the main framing right | 22:27 |
| xfxf | zoom out please | 22:28 |
| xfxf | you're cutting off his feet | 22:28 |
| xfxf | frame his entire body including head/feet inside of the frame | 22:28 |
| jea | but don't do it while you are on that shot please | 22:29 |
| av_plenary | What's interesting about his feet? | 22:29 |
| xfxf | the current framing doesn't look good | 22:29 |
| av_plenary | What about that last one? | 22:30 |
| jea | yes, that was alright | 22:30 |
| xfxf | that's better, thanks | 22:31 |
| xfxf | btw we wouldn't normally frame feet, but due to the angle of the camera in plenary, it's the only chance you have of making wanderers look half decent | 22:32 |
| av_plenary | We wanted to get closer on his face because it's so wonderfully animated | 22:32 |
| xfxf | that would be good but you have to be super fluid with tripod movements | 22:34 |
| av_plenary | The plan was to use the side camera and slides more to mask his going back to the podium | 22:34 |
| xfxf | okay, i was commenting on because what i was watching didn't look too hot | 22:34 |
| xfxf | if you think you can do it well, you're welcome to try again | 22:34 |
| av_plenary | Yeah, we haven't practiced this before. <grin> | 22:35 |
| xfxf | indeed, hence why suggesting easier framing | 22:35 |
