mithro I'm for using the cases as tripods :-P01:18
mithroRoadie Case Construction (
tpbTitle: Roadie Case Construction - Google Drawings (at
CarlFKmithro: what are the chances of telling the hdmi2usb to shift the output left/right ?01:22
mithroCarlFK: what do you mean?01:23
tumbleweedmithro: you shown that to rattus? (the case)01:23
mithroCarlFK: at the moment it only does one resolution on everything01:23
CarlFKseems a common problem with projectors is they don't ... center? the image.   sec.. I have the camera pointing at enough of the screen01:23
mithrotumbleweed: no idea, I've shared it a couple of times01:24
CarlFKmithro: I would want it to not touch the encoder output. I guess adjust one of the hdmi outputs01:24
mithroI'm currently at a work BBQ, so can't really do much01:24
CarlFKbut in a timing sort of way not ... moving pixels?01:25
mithrotumbleweed: I think my approach makes more sense when you have ptz cameras01:25
tumbleweedmithro: sure01:25
tumbleweedbut this is the kind of thing he's very interested in01:25
mithroCarlFK: well, we could give options to play with the front verse back porch of the video signal01:26
CarlFKand lots of other gear.  those cases are huge01:26
CarlFKmithro: yeah, that's what I was hoping for01:26
xfxfCarlFK: i see that with some 16:10 projectors when displaying a 16:9 image01:27
xfxfit's almost always a misconfiguration with either the projector or the scan converters between you and it01:27
mithroCarlFK: the likelihood of it happen is pretty low unless someone has the time to hack on it01:28
CarlFKxfxf: yeah, there was some $50? hdmi 2 vga converter that went to a vga port in a box on the stage floor that looked like it had about 20 years of dirt accumulated in it.01:30
xfxfnot surprised01:32
xfxf$50 says their av tech says they 'never have any problems' when in reality every second person has problems01:32
mithroCarlFK: there is a lot of things we could do, but I don't have the funds to pay for more than the basic stuff and nobody is stepping up to do volunteer it01:34
mithroWe could do all of cropping, padding, scaling and even compositing01:35
mithrossk1328 did a lot of the foundational work needed for scaling and compositing01:36
CarlFKmithro: I was hoping there is a constant stored somewhere and "just" make a command that will let me hammer in some other value01:36
xfxfmithro: assuming you're able to approximately estimate the work needed for features, is it worth putting up a $ and/or hours needed for things somewhere?01:36
xfxfthat said, i guess a lot of this stuff is difficult to estimate01:37
mithroCarlFK: there is kind of, if I understand correctly01:37
CarlFK   you can see the white color bar is over 1/2 off the side, and  it is not an optic problem - the white stops at the edge of the screen01:37
tpbTitle: Veyepar: Video eyeball produce and review. (at
CarlFKhey look, it is me dancing or something01:38
mithroBut I've yet to get you to actually modify the firmware, so I can't be bothered explaining.01:38
CarlFKwe had to pull the hdmi2usb because it messed up the display.  mac dp or whatever into the venue supplied  -> vga gizmo "worked"  (it put black bars top and sides)01:40
mithroI'll have to look on a computer, on my phone now01:41
xfxfnice beanie01:42
CarlFKoh, at 21:29 is Forest Mars  pitching Open Camps  = the crazycon in NYC UN headquarters01:42
CarlFKpeople envied my pomp pomp01:43

xfxfmithro: do your HDMI2USB's have power packs or just the units?  should i order more power bricks?05:58
mithroMine don't have power pack, but I have some thoughts, I found a couple small [email protected] supplies but still yet to find if I can get them online07:11
mithroI also have a box of 12V supplies but don't really want to be bringing to much07:12
mithroAnd they are opsis boards not HDMI2USBs07:12

xfxfmithro: do you twitch when i call it the wrong thing? ;-P10:29
xfxffrom hereon i'll call them the 'opsis hdmi2usb'10:30
mithroxfxf: I feel like if I answered yes to that you might do it more10:30
xfxfvalid point though, i guess 'opsis running hdmi2usb gateware' communicates that the hardware is intended to have life beyond the hdmi2usb usecase10:31
mithroxfxf: Well, kind of both ways - the HDMI2USB gateware runs on more than the Opsis and the Opsis can be used with more then the HDMI2USB gateware10:32
mithrobtw I'm on a bus to Canberra, so could disappear at any time...10:35

mithroxfxf: I hate audio23:43
mithroxfxf: I don't understand how I can manage to capture video so easily and audio always ends up being so hard...23:46
xfxfyeah, audio's always the fun one23:47
xfxfwhat's the specific issue you have?23:47
mithroThe USB capture / mixer doesn't seem to be produce way to low level sound from USB output - monitor is working fine23:49
mithroSo I ended up having to fall back to a boundary mic next to the speaker23:50
mithroIts kind of nice as it is picking up the audience23:50
mithroBut its still terrible :-P23:50
mithroAlso, you don't seem to have iris control on the panacontrol stuff23:52
xfxfugh, yeah, boundary mics aren't really that great for this sort of thing23:53
xfxfi use them strictly for panel's23:53
mithroI also have the problem that the audio is coming out of the headphone jack and the inbuilt speakers at the same time23:53
xfxfand i don't think i've touched the panacontrol script since two lca's ago23:53
mithroxfxf: I tweaked it a tiny bit23:54
xfxfmithro: in voctomix? that sounds like a pulseaudio issue23:54
mithroxfxf: Either pulse or alsa I think... but I've muted the "speaker" channel and have the headphones one unmuted but it still comes out of both23:54
xfxfand yes, audio is always our achilles heel23:55
xfxfit's probably the thing i'm most pedantic about when it comes to dealing with venues23:56
CarlFKmithro: what audio hardware are you using?23:58
CarlFKand yes, audio is hard23:59
mithroJust some crappy USB - something like
