Libcamera "simple" example usage has three files, 600 lines total. Good news is that it works, bad news is that it stops working almost as soon as I modify it... and not in a way that is easy to debug (segfault, debug trap, backtrace pointing to source line with "}"). I integrated it with SDL, and that was easy, got buffers mapped and translated to format that can be displayed. But when I try to close front camera and open back one, or to change resolution, bad things (tm) happen. Fact that empty build takes 15 seconds also does not help.

My code is at https://gitlab.com/tui/libcamera/-/commit/456a19f64e1b0959cdc9b1b9fa666963772a383c. Press "Snap" button to demonstrate the problem.

If you can help debugging it, or can get it to work, or know better example to start from, please let me know. Would not mind boosts. You may get libcamera based application to take photos / record videos on phones in future if we can get this to work.

@onthisday Split of Czechoslovakia was good. Meciar ended up on the other side of border. Fico is on the other side of border, and that is good, too. [If he tries to come here, I believe there will be big meeting of people telling him how welcome he is.] Now, if we only could return Babis to the right side of border. And Okamura, too.

Kobyla ma problem. Rada by me sezrala, jenze v mem okoli se zahadne objevuji jablka, a jablka ji chutnaji. Minule mi sla naproti tak akcne, ze se zlutak zacal bat o "svoje" jablka, a sel ke me snad dokonce cvalem.

Ale je to takove opatrne setkani. Kobyla mi oznami, ze by mi rada zkontrolovala kapsy, a ja ji reknu ze ani nahodou. Pak ji ja oznamim, ze bych ji rad sahnul na krk (coz vypada podezrele jako nasazeni ohlavky), a ona se vyjadri ze to ne. Takhle se chvili dohadujem, pak se vetsinou dohodnem, a pak se na zemi zahadne objevi jablko.

Dneska se opakoval obvykly scenar, az na to ze kobyla vibrovala. Mel bych ji prejet po cumaku doprava a rict "halo?". Ne to asi... Tak prvni zjistit, jestli se mi to nezda. Omlouvam se vsem, ktere jsem k tomu pouzil... A teda bohuzel nezdalo, ale holky sehnaly dalsi deku, a zaridily ji nadstandardni ubytovani v seniku.
