@tobykurien Is the organic maps installable using apt? I was using waydroid to get it running...

@ptesarik @ljs @cxberger Hehe. Someone should tell that to kernel CoC people. Apparently taking AI hallucinations, signing them with your and sending that out to confuse people is okay... Signing-off patches based on those hallucinations is okay, too.

@dos @datenwolf @dcz @martijnbraam @NekoCWD Thanks for the song, translation was easy :-).

I guess -- we are not using the vertex processing of the GPU at all, and that geometry distortion sounds like right job for it. Might need to be done per-color...

I did some stalking, and there's a lot of changes on your gitlab -- https://source.puri.sm/sebastian.krzyszkowiak . Is the video enconding code in the millipixels or somwhere else?

@jk Yeah, your friends and experts will be happy to do the work chatbot, google search, or stack overflow search could do.

@dos @datenwolf @dcz @martijnbraam @NekoCWD Lens corrections -- are we speaking lens shading or geometry corrections?

I am still eager to see your code. I'd like to try to tweak it for 1024x.. resolution, to get good quality videos.

@dos @datenwolf @dcz @martijnbraam @NekoCWD So, this is what I was targetting with my "gstreamer will downscale UV components" comment: GPU is doing heavy computation to make sure you have great color values for each pixel, only for gstreamer to discard it in the next step.

Anyway, I'd love to see the code :-).

@dos Not sure about performance implications of multiple render targets. (And yes, living with reasonably old distros is always good). I could live with Y-only viewfinder or maybe AYUV viewfinder is not free but "fast enough" :-).

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.

@ozzelot Yeah, well. Emacs is painful to run on a phone. I'd prefer not to control atari800 emulator using software keyboard :-).

@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.
