videoteamCarlFK, your test1 script is failing with a ffmpeg error on my machine00:22
videoteam** (gst-launch-1.0:13432): CRITICAL **: gst_ffmpeg_cfg_set_property: assertion 'qdata->size == sizeof (gint64)' failed00:22
videoteamactually, it looks like voctomix is just segfaulting...00:24
videoteam./ line 7: 14203 Segmentation fault      (core dumped) ./voctocore/ -i ../voctomix-outcasts/configs/light.ini00:24
videoteamHrm, it looks like voctocore is segfaulting about 75% of the time00:31
videoteamxfxf, have you seen this?00:31
xfxfonly with an older gstreamer00:32
xfxflatest gsteeamer in 16.04 working perfectly for me at Kiwi pycon right now00:32
videoteamThis is 16.04.0100:33
videoteamhrm, it seems to be something in carl's script00:35
videoteamLooks like this laptop is too slow to run voctomix + the gui at 720p00:41
mithroxfxf: What is your recommended voctomix laptop these days?00:43
mithroThis laptop seems to be a 2011, i3 -- Sandy Bridge00:55
mithroCarlFK: what are you running voctomix on?00:55
*** Bertl is now known as Bertl_zZ02:46
CarlFKmithro: Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz03:55
mithroIn what?03:55
CarlFKvideoteam: yeah, starting core segfaults now and then.  seems random.  yay.  upparrow, enter03:55
CarlFKmithro: desktop build around 201203:56
mithroI don't quite get Intel's naming scheme - what does the i3 verses i5 verses i7 mean?03:57
CarlFKmithro: me neither.03:58
CarlFKmithro: and I hear they did i3, i5, i7 and then a year later came out with another set of 3,5,7 know as 2nd gen03:58
CarlFKI hear this is a 2nd gen i303:59
mithroIt seems like the bigger value is better but the larger generations are always better03:59
mithroWhich gen is sandy bridge?04:00
CarlFKI think this 2nd gen one is04:01
mithroAnd you are using vocto mix and the gui on it?04:07
mithroThis i3 gen2 doesn't seem to be able to keep up...04:08
CarlFKmithro: i3: declink,, core, gui04:14
CarlFKlaptop atlys, usb ingest gig-e -> i3 (core)04:15
mithroHrm, 720p60?04:17
mithroAre you using the LCA.cfg file?04:25
CarlFKmithro: 720p60, here is the vocto config

mithroCarlFK: oh, you are running 30fps07:37

xfxfmithro: US cameras will be 60fps, the broadcast HD standards vary in countries to allow older SD content to be shown without whacky frame interpolation IIRC10:05
xfxfwe (PAL countries) are 5010:06
xfxfusually not something you can change on the camera either, annoyingly10:06
xfxfalso re laptops, i'm using lenovo 3rd gen's with the QM i7 series processor - they were the fastest laptops i could find which still had firewire ports10:08
xfxfcompute wise they're about the same performance as a modern 5th/6th gen standard i7 laptop processor (6500U?)10:08
xfxfthey work well, everything only eats 50-60% cpu which is nice overhead, but i expect that'll go up if we ever do 1080p + the power bricks for these things are crazy huge given the processor power draw10:09
xfxfi'm not sure i'd recommend them?  they're allright, i'll probably look at different things soon, just trying to get a setup locked down i'm happy with first10:09
xfxfi'd expect a 2nd gen i3 to probably run core+gui+1 ingest, but you'll be pretty close to 100% CPU10:09
xfxfoff memory the biggest difference between the i3's and i5/i7's is less cores and the cores won't dynamically boost10:10
xfxfbut we're dealing with multiple threads/processors so i don't think intel turboboost will make much difference10:10
xfxfprocesses*, rather10:10
xfxfturboboost much more advantageous with single threaded processes10:11
xfxfalso if you're looking at laptops take note of its thermal ability10:16
xfxfi'm currently encoding videos on my lenovo ultrabook which is a 4th gen i710:16
xfxfthe cores are only running at 50-60% max capacity though because the thermal properties/fan in this thing sucks so it's being throttled down10:17
xfxfso the capabilities of the actual cpu are irrelevant10:17

mithroxfxf: I'm looking at the lenovo laptops on their site at the moment11:37
mithroxfxf: They seem to be currently on sale11:37
mithroxfxf: I'm ponding their thin micro-station things too11:37
xfxflink me12:16
xfxfand they're usually always on sale, I've been eying off new ones for months12:17

cr1901_modernmithro: I successfully replaced the CPU clk PLL with two DCMs on minispartan6+. Unfortunately, the firmware crashes soon after :(.16:02
cr1901_modern(MiSoC BIOS is fine)16:02

tumbleweedmithro: did you ever get to the bottom of the issue with the opsis I was having? (where it wouldn't boot some images)22:31
