MEETING TIME!
16:00

vup
is here

Bertl
please go ahead vup
16:04
vup

so last week I started to implement one of the last "missing" features in narui (the ui framework for the recorder)
16:05
vup
Which is the ability to render parts of the UI "offscreen" and then use a custom shader to render it onto the main target
16:05
vup
The most common usecases of this are things like drop shadows, group opacity, backdrop blur and similar effects
16:06
vup
The implementation is still wip and (obviously) still has some bugs, but it was actually a lot simpler than expected
16:06
vup
(you can find the current code for it here: https://github.com/apertus-open-source-cinema/narui/pull/15)
16:06
vup
and a short demo of it here: https://files.niemo.de/2021-09-18%2003-17-11.mkv
16:07
vup
(I was too lazy to implement a reasonable UI effect, so you will have to do with wiggly text :P)
16:07
vup
thats it from me
16:07
Bertl
thanks a bunch!
16:08
Bertl
it looks like that's about it for today, anybody else who would like to report?

over the weekend, I dug out the HDMI Shield we designed and built a few years ago
16:11
Bertl
because now that we updated the gateware to handle raw data transfers, I wanted to evaluate how good the shield would perform as Preview Output in addition to two HDMI plugin modules which do the raw transport
16:11
Bertl
took some time to get the pinout right, because it seems I kind of swapped some pins on the shield interface back then, but the results are surprising
16:12
Bertl
at 1080p60 we get almost the same quality out of the shield than from the HDMI plugins, despite the fact that the header interface of the shields is really not suited for high speed transfers

Sorry, late. Hi all!
16:14
Bertl
I also updated the gateware to produce a slightly better A/B pattern for the raw HDMI transfer which requires way less computation to assemble the frames back
16:14
Bertl
it follows the monochrome layout and basically splits the lines into A/B frames
16:15
Bertl
this makes it kind of trivial to reassemble them into the raw data
16:15
Bertl
performance is good, everything is configurable so I guess the next steps are to push the limits of the HDMI digitizer
16:17
Bertl
I also got a visit from se6astian last week (he brought cake :) where we modified the fan headers on the Betas
16:17
Bertl
that's it from my side for this week
16:17
Bertl
cscar: anything you would like to report?
16:17
vup
nice stuff!
16:19
se6astian
I am in a live broadcast currently, thanks bertl for moderating
16:20
Bertl
se6astian: wanna report from your live broadcast? :)
16:21
se6astian
Sure, it's about identification of galactossyltransferase
16:21
se6astian
This current slide at least :)
16:22
Bertl
that's basically sugar transfer :)
16:23
cscar
Bertl: nothing really to report atm. Just following along (great progress BTW)
16:23
Bertl
okay, then I consider this meeting concluded!
16:24
Bertl
thanks everyone! see you all next week!
16:24
cscar
Your a fast moderator :D
16:24
