@dos Heh. Is my guess correct that it should be stride * HO, not WO * HO * 4? :-)

@dos I don't have much experiences with GUI programming, so I was looking for suggestions. I've got dma-buf handle but would not know what to do with it in gtk, and maybe SDL is better match. Or perhaps stick to original plan and do user interface ("take picture" button etc) in another process.

@dos There are at least two threads in this code: main one, and whatever runs "on_buffer_released". I don't yet know what causes the segfaults, but I suspect gstreamer.

@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.
