| sab_123 | mithro, ping | 03:40 |
| CarlFK | mithro: I don't see anything new in HDMI2USB-firmware-prebuilt/archive/master | 03:45 |
| mithro | CarlFK: it hasn't been merged yet, so you need to build it from source | 03:46 |
| CarlFK | then no | 03:46 |
| mithro | CarlFK: Okay, so I'll have to spend time working on that instead of making the eeprom flashing working | 03:47 |
| mithro | sab_123: just replied to your email | 03:49 |
| sab_123 | mithro, got it | 03:49 |

| xfxf | CarlFK: sorry, been busy the last few days - glad you got the blackmagic stuff working. the sync issues i was having might be fixed upstream, i dunno, recommend treating what i've said a possibility, not the absolute | 06:52 |
| xfxf | i did try upgrading my 16.04 notebook that gstreamer/vocto was crashing on two nights ago... and voctocore now loads without segfaulting | 06:53 |
| xfxf | so somebody fixed something \o/ | 06:53 |
| CarlFK | xfxf: oh yeah, I forgot about the crashing all the time | 06:53 |
| xfxf | sorry, that gstreamer/vocto was crashing on when 16.04 first came out. i upgraded it two days ago and it not works | 06:54 |
| xfxf | this wasn't crashing all of the time, it would crash completely on trying to load voctocore | 06:54 |
| xfxf | like it would never load ever on 16.04 | 06:54 |
| xfxf | i did some debug logs for the devs and they said it was def a gstreamer bug and to log with them | 06:54 |
| xfxf | this was months ago | 06:54 |
| CarlFK | yeah, im running 16.04 here, seems to be fine | 06:54 |
| xfxf | i'll try upgrading the deploy scripts you guys made at LCA to 16.04 and see what happens | 06:54 |
| xfxf | good | 06:55 |
| xfxf | hopefully the decklink bug is fixed in the version of gstreamer it uses | 06:55 |
| xfxf | i think a new gstreamer came out shortly after it, not sure how many months before release ubuntu freeze | 06:55 |
| CarlFK | something changed between 15.10 and 16.04 for the better | 06:56 |
| CarlFK | regarding the gst declink thing | 06:56 |
| CarlFK | on 15.10 I needed to run gst-master (git tip?) else it would .. crash? stop? something bad after like 2 minutes | 06:56 |
| xfxf | oh humm | 06:57 |
| xfxf | so | 06:57 |
| xfxf | https://launchpad.net/ubuntu/xenial/+source/gst-plugins-ugly1.0 | 06:57 |
| xfxf | says 1.8.2 | 06:57 |
| tpb | Title: Xenial (16.04) : gst-plugins-ugly1.0 package : Ubuntu (at launchpad.net) | 06:57 |

| tpb | Title: GStreamer 1.8 release notes (at gstreamer.freedesktop.org) | 06:57 |
| xfxf | 1.8.2 is super recent, like, this month | 06:57 |
| xfxf | are ubuntu versioning their stuff different or do they now track minor revisions from upstream within a release? | 06:57 |
| xfxf | actually maybe i'm mis-remembering, i thought debian policy was to freeze a release entirely and only backport fixes | 06:57 |
| xfxf | but maybe they always tracked minor releases | 06:58 |
| xfxf | either way, that fills me with confidence, good | 06:58 |
| CarlFK | Uploaded: 2016-06-22 | 06:58 |
| CarlFK | that was like 4 days ago | 06:58 |
| xfxf | yeah but that's reflective of a build/upload date, not nessecarily upstream | 06:59 |

| xfxf | i can see thaytan's commit there + a few others | 07:03 |
| xfxf | maybe that bug is fixed | 07:03 |
| xfxf | in 1.8.2 | 07:03 |

| CarlFK | xfxf: can you give me some pointers on which of the 3 720 modes I should be using ? | 07:26 |
| CarlFK | gst-inspect-1.0 decklinkvideosrc | 07:27 |
| xfxf | how do you mean | 07:27 |
| CarlFK | (17): HD720 50p - 720p50 | 07:27 |
| CarlFK | (18): HD720 59.94p - 720p5994 | 07:27 |
| CarlFK | (19): HD720 60p - 720p60 | 07:27 |
| xfxf | You use the one that matches your other inputs and what your camera is outputting | 07:28 |
| xfxf | For you that's probably 18 | 07:28 |
| CarlFK | does the hdmi2usb 's output matter ? | 07:28 |
| xfxf | you don't want to drop frames mixing multiple sources | 07:29 |
| xfxf | you want all at the same framerate | 07:29 |
| xfxf | Or it'll look a bit rubbish with motion | 07:29 |
| CarlFK | that sounds like Yes | 07:29 |
| xfxf | Assuming gst pipelines convert | 07:29 |
| xfxf | So yes | 07:29 |
| CarlFK | HDMI2USB>m list | 07:31 |
| CarlFK | mode 9: 1280x720 @60Hz | 07:31 |
| CarlFK | mode 10: 1280x720 @50Hz | 07:31 |
| CarlFK | does usa's 60hz matter ? | 07:31 |
| xfxf | it depends on your camera | 07:31 |
| CarlFK | I have been using 9 | 07:31 |
| CarlFK | that's the HDMI2USB | 07:31 |
| xfxf | 60hz is prob ideal for you yes | 07:31 |
| CarlFK | so HDMI2USB mode 9: 1280x720 @60Hz | 07:32 |
| CarlFK | camera / declink 59.94 or 60 ? | 07:33 |

| xfxf | 30000/1001 is exactly 59.94/2 | 08:38 |

| mobydikc | CarlFK: easy way to setup grabber (second channel in gui) to a custom image? | 23:09 |
| CarlFK | mobydikc: heh - the DebConf folk were just working on that | 23:09 |
| CarlFK | mobydikc: there are a few reasons you might want that.. what are you trying to do? | 23:10 |
| mobydikc | I'm trying to be lazy | 23:29 |
| *** Bertl_zZ is now known as Bertl | 23:30 | |
| mobydikc | I figured I could just setup the image on a computer and use the hdmi capture ethernet thingy unit | 23:30 |
| mobydikc | But it's taking me longer to setup the studio for video shots than I thought | 23:30 |
| mobydikc | So if there was an easy short cut, I figured I'd ask. I know, there's --help and stuff, but I'm vacuuming the stage | 23:31 |
| mobydikc | It's basically like a presentation where the presenter has one slide | 23:32 |
