| videoteam | CarlFK, your test1 script is failing with a ffmpeg error on my machine | 00:22 |
|---|---|---|
| videoteam | ** (gst-launch-1.0:13432): CRITICAL **: gst_ffmpeg_cfg_set_property: assertion 'qdata->size == sizeof (gint64)' failed | 00:22 |
| videoteam | actually, it looks like voctomix is just segfaulting... | 00:24 |
| videoteam | ./test1.sh: line 7: 14203 Segmentation fault (core dumped) ./voctocore/voctocore.py -i ../voctomix-outcasts/configs/light.ini | 00:24 |
| videoteam | Hrm, it looks like voctocore is segfaulting about 75% of the time | 00:31 |
| videoteam | xfxf, have you seen this? | 00:31 |
| xfxf | only with an older gstreamer | 00:32 |
| xfxf | latest gsteeamer in 16.04 working perfectly for me at Kiwi pycon right now | 00:32 |
| videoteam | This is 16.04.01 | 00:33 |
| videoteam | hrm, it seems to be something in carl's script | 00:35 |
| videoteam | Looks like this laptop is too slow to run voctomix + the gui at 720p | 00:41 |
| mithro | xfxf: What is your recommended voctomix laptop these days? | 00:43 |
| mithro | This laptop seems to be a 2011, i3 -- Sandy Bridge | 00:55 |
| mithro | CarlFK: what are you running voctomix on? | 00:55 |
| *** Bertl is now known as Bertl_zZ | 02:46 | |
| CarlFK | mithro: Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz | 03:55 |
| mithro | In what? | 03:55 |
| CarlFK | videoteam: yeah, starting core segfaults now and then. seems random. yay. upparrow, enter | 03:55 |
| CarlFK | mithro: desktop build around 2012 | 03:56 |
| mithro | I don't quite get Intel's naming scheme - what does the i3 verses i5 verses i7 mean? | 03:57 |
| CarlFK | mithro: me neither. | 03:58 |
| CarlFK | mithro: 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 gen | 03:58 |
| CarlFK | I hear this is a 2nd gen i3 | 03:59 |
| mithro | It seems like the bigger value is better but the larger generations are always better | 03:59 |
| CarlFK | right | 03:59 |
| mithro | Which gen is sandy bridge? | 04:00 |
| CarlFK | I think this 2nd gen one is | 04:01 |
| mithro | And you are using vocto mix and the gui on it? | 04:07 |
| mithro | This i3 gen2 doesn't seem to be able to keep up... | 04:08 |
| CarlFK | mithro: i3: declink, ingest.py, core, gui | 04:14 |
| CarlFK | laptop atlys, usb ingest gig-e -> i3 (core) | 04:15 |
| mithro | Hrm, 720p60? | 04:17 |
| mithro | Are you using the LCA.cfg file? | 04:25 |
| CarlFK | mithro: 720p60, here is the vocto config https://github.com/CarlFK/veyepar/blob/master/setup/nodes/pxe/shaz/var/www/lc/late.sh#L322-L337 | 05:21 |
| tpb | Title: veyepar/late.sh at master · CarlFK/veyepar · GitHub (at github.com) | 05:21 |
| mithro | CarlFK: oh, you are running 30fps | 07:37 |

| xfxf | mithro: US cameras will be 60fps, the broadcast HD standards vary in countries to allow older SD content to be shown without whacky frame interpolation IIRC | 10:05 |
| xfxf | we (PAL countries) are 50 | 10:06 |
| xfxf | usually not something you can change on the camera either, annoyingly | 10:06 |
| xfxf | also 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 ports | 10:08 |
| xfxf | compute wise they're about the same performance as a modern 5th/6th gen standard i7 laptop processor (6500U?) | 10:08 |
| xfxf | they 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 draw | 10:09 |
| xfxf | i'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 first | 10:09 |
| xfxf | i'd expect a 2nd gen i3 to probably run core+gui+1 ingest, but you'll be pretty close to 100% CPU | 10:09 |
| xfxf | off memory the biggest difference between the i3's and i5/i7's is less cores and the cores won't dynamically boost | 10:10 |
| xfxf | but we're dealing with multiple threads/processors so i don't think intel turboboost will make much difference | 10:10 |
| xfxf | processes*, rather | 10:10 |
| xfxf | turboboost much more advantageous with single threaded processes | 10:11 |
| xfxf | also if you're looking at laptops take note of its thermal ability | 10:16 |
| xfxf | i'm currently encoding videos on my lenovo ultrabook which is a 4th gen i7 | 10:16 |
| xfxf | the cores are only running at 50-60% max capacity though because the thermal properties/fan in this thing sucks so it's being throttled down | 10:17 |
| xfxf | so the capabilities of the actual cpu are irrelevant | 10:17 |
| *** puck has joined #timvideos | 11:34 | |
| mithro | xfxf: I'm looking at the lenovo laptops on their site at the moment | 11:37 |
| mithro | xfxf: They seem to be currently on sale | 11:37 |
| mithro | xfxf: I'm ponding their thin micro-station things too | 11:37 |
| xfxf | link me | 12:16 |
| xfxf | and they're usually always on sale, I've been eying off new ones for months | 12:17 |

| cr1901_modern | mithro: I successfully replaced the CPU clk PLL with two DCMs on minispartan6+. Unfortunately, the firmware crashes soon after :(. | 16:02 |
