Today it is clear that Meta/Facebook is breaking the law again. "You have to agree". "Pay or okay". No, it is not okay. Find me at https://social.kernel.org/pavel .

@ozzelot Oh, and it would be great if we could go back to 1980, and create 6502-based machine with touchscreen. That would give us nice software to run on smartwatch and maybe even phones.
I wonder if Palm emulator would be fun to play with, and if it has enough interesting apps to be worth the effort.

@datenwolf Thanks! I added ui overlay to the code and pushed it to https://gitlab.com/tui/debayer-gpu/-/tree/master/glsl?ref_type=heads ... Would you be willing to hack a bit more on it? Flow should be camera -> debayer -> fbo -> downscale and combine with ui overlay -> display. Copying data from fbo is slow, so it needs to be done in separate thread, in paralel with GPU computations, but I can handle that, once I get memory mapping (I believe).

@dos I want to see how you do that magic... to see if it looks reasonable or if I should keep playing with sdl. Note that first thing gstreamer will do is downscale color information. If you do that in shader -- YUY2 -- gstreamer will be faster. But having 512x.. image with perfect color in each pixel is a waste with h264 compression

@dos I have feeling that you'll post few more advancements and then you'll disappear, with that code being gone forever. Probably abducted by aliens as that's clearly alien code :-).
Please publish it somewhere.... we don't want another "Fermat's last theorem" situation.
Also, yes, at 512x.. resolution, things are likely easier. I had a lot of fun trying to get gtk/gstreamer working, and while I got it to work _somehow_, I was not really able to understand/debug performance issues.

Modra neni dobra, modra je kriterium
Kdysi jsem vyrazil ke zlutakovi v modrym cyklodresu. Nenechal na sebe sahnout, pohyboval se tak, aby byl centimetr od moji ruky. Musel jsem se jit prevlict.
Dneska jsem k nemu vyrazil v modry (nepromokavy) bunde. Jako jo. Na zavolani prisel, jen velmi, velmi, velmi opatrne. Mrkev si vzal a nasledoval me, ale dal dost jasne najevo ze ven z vybehu se mnou nepujde. Proste se choval jako pred rokem? lety? Pry me nezna a nikam se mnou nejde. Zda se, ze modra je kriterum.

@dexternemrod If you have to ask, then probably #droidian :-). Is your goal to have something "stable" (-> #mobian) or is your goal to be on "bleeding edge" (-> #postmarketos)? Do you need working camera? (-> #postmarketos, probably).

@datenwolf So I did some asking, and it looks like it is cache coherency problem on ARM CPUs and there's no easy way around.
I got your code to run on both Librem 5 and a notebook, thanks. Could you add a copyright notice and some kind of license, preferably GPLv2+ compatible?

@dos @datenwolf @dcz @martijnbraam @NekoCWD I guess that for 120 fps video, you'd want to capture a burst to available memory, and do the conversion after the capture is done.
Could we get some intermediate (maybe cropped) modes, too? For digital zoom, or maybe for cases where performance is not available to deal with full image.

@dos @datenwolf @dcz @martijnbraam @NekoCWD If you have something where you can draw / handle controls on top of the viewfinder, or at least around it. I did some hacks in the past with capturing gstreamer window, but they were a) probably X11 specific and b) not really great code. If you have nice solution, I'd like to see one.
