Hi, I'm afraid I won't be able to go to the conference now at all. I checked at work and I can't get the time off. D:
<gchristensen>
oh goibhniu I'm so sorry :(
<goibhniu>
I wonder if adisbladis, andi- and others are still happy to take care of the video. I can certainly provide remote support, and help with getting things organised still.
<goibhniu>
Thanks gchristensen, it's a pity
<goibhniu>
I can also send over some equipment.
<andi->
goibhniu: I am confident we get some kind of solution/workaround. We do not need the perfect streaming we had the last years. Just recording everything and streaming slides+audio should be enough in the worst case.
<goibhniu>
Excellent!
<andi->
We can (and should!) put in the effort to give the recordings the final touch eventually in that case.
<goibhniu>
I'm certainly happy do some "training" sessions, if anyone's interested in learning about the setup we've used before. It's really very easy to do once you're familiar with it.
<samueldr>
and some of the training doesn't require the hardware; e.g. getting acquainted with obs
<samueldr>
sad to hear that though :/

I was also looking into alternatives to OBS. I would really like just everything being recorded and then afterwards mixed together if we lack people. A few ffmpeg invocations should do that. We probably want a live-preview and stream anyway.
<samueldr>
obs is used to compose and switch the inputs live, mostly
<samueldr>
though yeah, ideally those inputs would be saved and re-composed later on
<samueldr>
but that takes time
<samueldr>
I think that's why the obs recording was used for the final renders
<andi->
yeah, I just fear with lack of manpower comes mistakes and those are hard to correct afterwards :) But at this point this is just a detail.
<samueldr>
though I guess that ffmpeg recording can happen while obs is live compositing
<samueldr>
I'm not sure though if obs live compositing requires a beefier machine, e.g. one with gpu-accelerated encoding
<andi->
yeah, we definitly need to give it a test run. Not sure what kind of devices it will run on.
<samueldr>
hah
<samueldr>
goibhniu: I think you know about that last question
<andi->
adisbladis was working on a budget/item list that we might consider buying for recording our own conferences in the future.
<samueldr>
obs itself, for practice purposes, will run fine on even a 4th gen i5
<samueldr>
it's for live streaming and encoding that it may need hardware acceleration
<samueldr>
I'm sure it runs fine on even older vintage CPUs for training purposes
Synthetica has quit [Quit: Connection closed for inactivity]
<goibhniu>
Hrm, I vaguely remember trying to dump the unmixed streams separately from the mixed one, but I didn't find a nice way to do it.
<goibhniu>
I was using hardware accelerated encoding (nvenc)
<goibhniu>
We used two frame grabbers for the camera and laptop output streams.
<goibhniu>
The audio was a bit unstable though. I ended up using JACK for that, which was more reliable, but sometimes died too.
<goibhniu>
One thing I was planning to do this year is to set the white balance and exposure manually on the camera.
<goibhniu>
I believe there is a window behind the speaker again this year, which throws off the automatic settings.
<samueldr>
that sounds about right
<samueldr>
though wouldn't that also need to be adjusted depending on the cloud cover and sun position? (I don't have much experience)
<andi->
maybe we can just shade the speaker :D
<samueldr>
*wearing some sick shades*
<goibhniu>
I was hoping that it would be mostly okay for the speaker, although the background would get over and under exposed.
<goibhniu>
putting something behind the speaker would be ideal ^_^
<andi->
They surely have some kind of lights in that building I hope
<samueldr>
my intuition is that the over-exposition of the background would have "bloomed" and swamped the speaker, but... I don't know much about that :)
<Ox4A6F>
Do we have some spot lights? And maybe a cancas to hide such difficult backgrounds like a window.
<samueldr>
as long as the speakers themselves are constantly exposed I figure it's fine
<andi->
who needs speaker anyway? Just slides and audio! ;)
