OTOH, more flexibility with the application means people will play with it more during the talk, which means worse videos. I think what we have is just fine, and we don't need to change that any. > (3) Opsis still has a way to go but is already much better (and more stable) > than the old TwinPacks Better? Sure. Stable? Not so sure. I did see a whole lot of flickering going on, and that's definitely something we need to work on. It's absolutely good that we can support more than just VGA, and that we can support higher resolutions than 800x600 without too many issues; but there's still some work to be done.

There were seven people in the room: highvoltage, tumbleweed, olasd, pollo, and myself; and bdale and keith as "audience".

The slides are very basic; they don't contain a lot of information. Still, you can get them here: https://nextcloud.grep.be/index.php/s/Hd9idJdmdSdAZw7 I did forget to add a slide about the opsis boards, but we talked about those too, in between the final two slides.

I was going to schedule it for today, but I came up fairly late with the idea and didn't schedule it in time, so hence the move to tomorrow. If the suggested slot doesn't work for anyone, please speak up soon so I can reschedule it. Also, if someone wants to join in on this talk, let me know. I guess someone should do slides?

Would you be okay with that? If so, are there any scheduling issues that I should be aware of in case our talk gets accepted and I need to put it on the board?
