Passing data from camera to OpenGL broke my mind. The code is still far from what I'd call nice, but feel free to steal anything you want! Once I verify that debayering still works (I originally tested it years ago), GPU progress will

There are two main differences. First, libobscura doesn't yet fully support even UVC webcams, and second, related to the quote, is that you will not run into segfault with libobscura no matter how hard you try. When using libcamera, th

I guess my initial reaction was wrong: not having code in non-English languages doesn't accurately represent developer sentiments. There's a lot of translation efforts in open source, but again, this is not a good proxy for the se

Why is that a good thing? I get the idea that a common language is beneficial, but the flip side is the knowledge and effort of the people who know another language. That's lost due to never being opened (I guess that's more of an

Thanks for the report. I don't have access to Safari, so there isn't much I can do right now :/

You can use QtCreator that way already: https://dorotac.eu/posts/debugging_rust/ You can view the data structures opaquely even though the functions are written not in Rust, but in Python. One of the difficulties

Start in the middle. It's the most interesting part, too. After all, that's the core of your idea. I don't know where I heard this, but the idea is so important to me that I saved it on my blog: https://dorotac.eu&

Thanks! That's the Markdown renderer failing to escape entities properly. Fixed now by switching to markdown-it-py.

With my Librem 5 developer hat on, I'm surprised that a SPI chip matters at all. The Librem 5 eMMC contains a hidden "partition", which is preferred by the CPU to boot from over the "data partition" where the OS boo

I'm not a Rust-only developer, but a general systems programmer, and my foray into embedded is limited to a side project (see my profile), but no, I haven't switched to C/C++. Rust brings too much goodness to give it up. Rust

Based on the comments, telekom.de is doing the same thing. A /56 prefix, changing every day. Blood-boiling. Can anyone recommend an EU-based server provider that could be used as a tunnel?

That's a valid observation of one of the reasons I won't use git-send-email. I have limited mental resources, and given the choice between a tool where I have to spend half an hour before I can begin using it, and a tool which wil

I can figure out how to send you a patch set via email (see my Linux kernel contributions), but if I can avoid doing that, sure as heck I will. Your project must be really important to me, or I have to get paid. As for the reason, it's

I hope so too :) Sadly, Megapixels doesn't seem to be interested in libcamera at the moment.

Did you do your tests in good lighting? Did you compare raw sensor output, or post-processed? Big sensors capture more light and have more bokeh. With enough light, the first doesn't matter, and bokeh is not a thing for QR codes. If yo

It's not orthogonal. In fact, it's a very good observation, and even libcamera itself recognizes it by providing v4l2 emulation. It could be a viable way to get the basic use case of video streaming where special controls are not

That's because we need a standard, and without libcamera, there is no standard.

It's hard to tell because I don't know what Android phones do exactly. Does it vary by manufacturer? Do we include AI tricks and high speed video encoding? I think it's going to be a long way to get there, but also the openne
