@ozzelot That's... quite clever and true. But often having some code is better than having no code...

@eevee I used LLM to translate into czech and get summary. Should I feel bad? :-). There are good uses for LLM, and yes, that includes "startrek", but someone will have to do that. And yes, I tried to start (but did not get far, so far).

@sesivany @dodo1095zd @mcepl V prenosove siti se problemy siri rychlosti svetla. Proto byva zvykem sit shodit do konfigurace "po jednom selhani" uz ve chvili, kdy se o tom dozvim.

Coz vlastne moc nevysvetluje. Pockal bych na nejake vysetrovani.

@dos That gstreamer code in C is scary. Multiple threads, no locking, what could go wrong?

@datenwolf Thanks a lot. I took a look and got it to build but not run so far. I got distracted by.. other camera code and real life. https://gitlab.com/tui/tui/-/tree/master/icam?ref_type=heads (We had blackout today).

@dos I don't believe gstreamer can handle complex cameras. But yes, eventually this code should disappear into libraries somewhere.

Ty kupy mrtvych civlistu v Gaze zacinaji byt tak velke, ze "smrt IDF" se pomalu presouva z kategorie "hnusny extremismus" smerem ke kategorii "vlastne docela rozumny pozadavek na zastaveni genocidy" :-(.

@dos Okay, I pushed code to https://gitlab.com/tui/tui/-/tree/master/icam?ref_type=heads . Debugging this may be a bit "fun".

Do I guess correctly that shaders can do arbitrary resolutions, such as 800x600?

I like the v4l+shaders integration. I'm not sure if I like the v4l+shaders+gstreamer integration.

@dos Yeah, I played a bit. Nice. But segfaults, occasionaly, and may segfault more when I switch to matroskamux. So I guess crash may be gstreamer-related? :-). There's also some kind of noise in bottom right corner, maybe that's related, too.

@dos Thanks, I got it to work. I'm putting it into tui repository... and will probably need to reindent it.

For me, there's about 50% CPU usage, so there's still some room.

Yes, YUY2 will be faster; it will also have lower color resolution.

And agreed, there's nothing magic about fences. There's nothing magic about riding horse w/o reins and nothing magic about flying 737, either :-).

@dos Yes, there's more work to be done in the kernel; sometimes camera does not work after reboot, bayer-10 modes are not supported, ... :-(. And yes, it will take more power, but with phase-detection AF, it should be significantly better camera.

@dos :-) Hopefully. I'll believe things when I see them running locally.

BTW there's one more important thing this can probably do: take full-resolution photos while recording video.

@dos Thank you! I'll take closer look tomorrow or over the weekend. In the meantime, would you have Makefile or build command that goes with it?

@dos Exactly. That's a bit of big deal. That's why I'm trying to make sure this code does not go away. I had phase-detection auto-focus working at one point, but decided it is unusable as I did not see a way to scale down images quickly enough.

Plus it also adds possibility of zooming.

@dos Fences; that must be some kind of dark magic.

This code seems too good to be true. So, just to be sure, and in case you disappear tomorrow, can I add /* Copyright 2025 Sebastian Krzyszkowiak, GPLv2 */ and act according to that?

Reply to @fell@ma.fellr.net
@fell @zaunz @postmarketOS The "pretty zoomed in" may be hardware limitation. The "90% range" is likely normal, too -- that's just how focus works. (Diopters, 1/m). But I like this. this is a real progress compared to my information from yesterday.
