mithroCarlFK, ping?02:28
CarlFK mithro - what's up02:28
mithroNothing urgent, just wanted to sync up with plans for the year and such02:28
CarlFKgood Q02:30
CarlFKI just heard some encouraging chatter with a phone call with this years PyOhio chair02:30
CarlFK"last year we were going to have a 5th track for odd talks that were not really python, or were by a vendor that were a little to spammy to be in the normal rooms.  we selected presenters, told them they would get to speak, but would not be videoed.  ....02:32
CarlFKat least 2 of them declined because of no video.02:32
CarlFKOne was academic, and his funding would not cover his travel expenses if there was no video."02:32
CarlFKpyOhio chair: Brian Costlow02:52
CarlFKhe also wants to figure out how to get the PSF to give video real funding02:52
CarlFKnot $2500 for a 4 room event02:52
mithroCarlFK, so my goals for 2014 are02:54
mithroa) Get the HDMI2USB prototype board being used regularly and reliably at multiple locations / events02:55
mithrob) Get the HDMI2USB production device available to the general public (by EOY)02:55
mithroCarlFK, you have an Atlys board right?02:56
mithroCarlFK, I finally have 2 box options02:57
mithroCarlFK, would it be better for me to send you a complete box, or for me to send you a design you can mill / cut yourself?02:57
CarlFKI do have access to stuff and likely people to do it02:58
mithro(complete box would still need construction)02:58
mithroCarlFK, do you have access to a laser cutter, or just a mill?02:59
CarlFKsend me desings, I'll hand it off to the local people and see what they say02:59
mithroCarlFK, on a laser cutter you can do the box in probably 1-2 hours02:59
mithroCarlFK, when is the last time you used the device?03:00
CarlFKthe Atlyes?  good Q. I keep taking it out and hooking it up, but never get around to actually feeding DVswitch03:00
mithroCarlFK, oh - did you see that Jan did a proper gst-switch plugin for feeding dvswitch?03:01
CarlFKkinda - will that read from a webcam03:01
CarlFKer, yes it will.  how do I make it read from a webcam? ;)03:02
tpbTitle: timvideos/dvsource-v4l2-other · GitHub (at
mithroWe where playing with it, and it should have 1 frame delay from the source to DVSwitch03:03
mithroonce I get around to porting to pygst (rather then just using gst-launch) I'll be able to put probes to give you the exact details03:03
CarlFKfake source - is that a test pattern ?03:03
mithroCarlFK, yes03:03
mithrothere are a whole lot of possible fake sources :)03:04
mithroI've found ball is good for testing03:04
CarlFKoh, that ball..03:04
CarlFKany test patterns are good for testing - requiring real inputs has bothered me forever03:05
CarlFKand my 1 frame DV files also bother me03:05
CarlFKare you around in about an hour?03:05
CarlFK9pm need to eat something, then I want to play with this03:06
mithroCarlFK, yes I'll be around in 1 hour03:06
CarlFKI'll be back here as soon as I eat03:08
CarlFKmithro: why is that forked from my repo?  did I write it and forget about it?04:38
mithroCarlFK, dunno, possibly04:38
mithroCarlFK, maybe you forked from my original repo04:39
mithrobefore I moved it from my username to timvideos04:39
CarlFKyeah, I think that's it.  kinda.  close enough04:40
