| xfxf | CarlFK: what's your current recording setup equipment/software wise? blackmagic pci-e card + hdmi2usb + voctomix? | 00:28 |
|---|---|---|
| xfxf | and if so, what ver of ubuntu (and are you running a custom gstreamer?) | 00:28 |
| CarlFK | xfxf: I have been using wily, but will rebuild and test using xenial in the next few days | 00:35 |
| CarlFK | on my wily box, I did have to use gst-master to run the blackmagic capture | 00:35 |
| CarlFK | and vocto did not run under that.. so fun making sure each was using the right gst libs | 00:36 |
| CarlFK | i 'think' everything I use is in https://github.com/CarlFK/voctomix-outcasts | 00:36 |
| tpb | Title: GitHub - CarlFK/voctomix-outcasts (at github.com) | 00:36 |
| xfxf | right, so same as what we did at LCA then | 00:36 |
| xfxf | is your equipment as i describe above? | 00:37 |
| xfxf | i'm putting boxes together for pycon au | 00:37 |
| xfxf | problem is i don't want to use a pci-e card if possible, i'd like to move back to laptops | 00:37 |
| xfxf | i've got some newer fast i7 laptops now that have usb3 + expresscard | 00:37 |
| xfxf | ideally would use 2x HDMI2USB's but not sure if it'll work OK with my camera | 00:37 |
| CarlFK | yeah.. I am using the card, mainly because I want to use the camera's audio | 00:37 |
| CarlFK | https://github.com/CarlFK/dvsmon/blob/master/vocto-prod1.py | 00:38 |
| tpb | Title: dvsmon/vocto-prod1.py at master · CarlFK/dvsmon · GitHub (at github.com) | 00:38 |
| xfxf | yeah, nod, avoids sync issues | 00:38 |
| xfxf | so pycon au is local to me so using 4x desktops isn't a problem | 00:38 |
| CarlFK | and more complicated setup having audio on it's own hardware | 00:38 |
| xfxf | but i do others interstate/overseas so i can't use desktops | 00:38 |
| xfxf | blackmagic unfortuantely not an option, their usb option doesn't work well under linux | 00:38 |
| xfxf | i wonder what expresscard options exist | 00:39 |
| xfxf | expresscard > pci-e would be an option if they weren't so expensive | 00:39 |
| CarlFK | http://www.bhphotovideo.com/c/used/1096582/jvc_gy_hm200_gy_hm220_4kcam_streaming_camcorder.html | 00:39 |
| tpb | Title: Used JVC GY-HM200 4KCAM Compact Handheld Camcorder GY-HM200 B (at www.bhphotovideo.com) | 00:39 |
| CarlFK | I plan on getting one of those ... maybe 2. just because of what you say | 00:39 |
| CarlFK | er.. so I can do laptop | 00:39 |
| CarlFK | but dam is that expensive. | 00:40 |
| CarlFK | really hard to justify. | 00:40 |
| xfxf | yeah those cameras look good | 00:40 |
| xfxf | also CCC said to use those, not me | 00:41 |
| xfxf | i never have :) but they sound like a great idea | 00:41 |
| xfxf | i've already invested in a few canon prosumer HD's though, so buying new cameras not an option currently | 00:41 |
| xfxf | USD$1600 is pretty decent for that camera though tbh | 00:41 |
| xfxf | the canons i have are about the same | 00:41 |
| CarlFK | that makes me feel better | 00:41 |
| CarlFK | and what you said about desktops | 00:41 |
| xfxf | still need a solution that'll work on a laptop though | 00:44 |
| xfxf | mithro: when you get a sec can you ping me with your recommendations for pycon au? i've poked you a few times, yet to hear back, assume you're busy but need some answers/help | 00:44 |
| xfxf | current 'solution' is SD mixing using dvswitch again. can't use firewire reliably with voctomix due to the gstreamer firewire stuff being a bit rubbish and falling out of sync | 00:45 |
| CarlFK | xfxf: for pycon au can't you use desktops and bm pci cards? | 00:45 |
| xfxf | i have another conference in NZ a month after that. i don't want to setup one thing that i can't use later | 00:46 |
| CarlFK | ah | 00:46 |
| xfxf | also i was still having sync issues with blackmagic+hdmi2usb with vocto at LCA | 00:47 |
| xfxf | assume you haven't had any problems? | 00:47 |
| xfxf | something must have been fixed upstream | 00:47 |
| CarlFK | or i haven't payed close enough attention | 00:47 |
| xfxf | if you've only been recording 1 hour things you probably won't notice | 00:48 |
| xfxf | it usually happens after 1-3 hours of recording | 00:48 |
| xfxf | audio starts to drift wildly out of sync | 00:48 |
| xfxf | it usually happens within a 1 hour period too but it'll only be a few frames out, so you won't notice unless you're looking hard at lip sync | 00:48 |
| xfxf | it's inconsistent, too, haven't determined the exact parameters that cause it | 00:49 |
| xfxf | it'll indefinitely happen but how much and when is up in the air | 00:49 |
| CarlFK | from what inputs? | 00:49 |
| xfxf | same as LCA. remote laptop w/ hdmi2usb, local PC with vocto + blackmagic hdmi card feeding audio+camera | 00:50 |
| *** sb0 has joined #timvideos | 01:15 | |
| CarlFK | xfxf: I'll start testing the hell out of things in about 12 hours | 01:16 |
| xfxf | cool, good luck! | 01:17 |
| mithro | xfxf: I said we should put together a doc for PyCon AU | 01:45 |
| mithro | For testing, you should be using head unless I say otherwise | 01:46 |
| mithro | That is problematic for Atlys boards at the moment | 01:46 |
| xfxf | i'd like to use the Opsis's, if it works for that, I'm happy to give that a go | 01:47 |
| mithro | CarlFK: was able to find when the Atlys stuff broke, so it shouldn't be too hard to solve | 01:47 |
| mithro | But I was hoping the liteDRAM upgrade that _florent_ had been working on would be finished by now | 01:48 |
| xfxf | is your expectation that we can use the HDMI2USB's for both the camera and the presenter? | 01:49 |
| xfxf | because that would be my preferred option, we already own enough | 01:49 |
| mithro | And that should properly fix there Atlys problem | 01:49 |
| mithro | Sure, if your camera supports 720p output | 01:50 |
| xfxf | yes, it does, but we had the issue with the input on the opsis's and requiring the redmere cable | 01:50 |
| xfxf | and i recall trying a gender changer so i could use a mini hdmi > hdmi + redmere and it didn't work | 01:50 |
| mithro | 720p DVI output that is | 01:51 |
| xfxf | it works perfectly on the atlys | 01:51 |
| xfxf | so i assume that's what it does | 01:51 |
| xfxf | note: i only have one atlys, so that won't work for 4x rooms | 01:51 |
| mithro | If it works on the Atlys, then it should work on the Opsis | 01:51 |
| xfxf | ah | 01:51 |

| xfxf | i should order some | 01:51 |
| mithro | xfxf: Sound like it | 01:54 |
| mithro | xfxf: I believe DebCamp starts tomorrow | 01:54 |
| mithro | xfxf: I believe they are also going to use vocto and hdmi2usb+blackmagic | 01:55 |
| mithro | xfxf: you should invest in getting an AXIOM sometime | 01:55 |
| CarlFK | mithro: whats AXIOM ? | 01:56 |
