[Feature request]: Replace unmaintained v4l crate with some better alternative

[jirutka]

Please describe your feature request

Crate v4l from raymanfx/libv4l-rs is buggy (#43, #16) and seems to be unmaintained (see opened pull requests).

It fails to build on Alpine Linux (musl libc) due to wrong types, I had to patch it (which is a bit tricky for rust dependencies). I managed to build it on 64-bit architectures (and published Alpine package), but there are more problems on 32-bit architectures (armv7).

Hi, libv4l-rs author here. I'd be happy to review patches to improve the armv7 and musl support - would you mind opening PRs so we can go through the changes together? Other issues can be sorted out as well I'm sure.

On that note it does not seem like there are any alternatives to libv4l-rs at all, not to mention a "better" one: https://crates.io/search?q=v4l

Glad you're back by the way, @raymanfx!

I'd be happy to review patches to improve the armv7

There are many problems with types on 32-bit arches (not just armv7). I’m sorry, but I don’t care enough about 32-bit architectures to invest my time in it. Maybe @PureTryOut from postmartketOS will be interested.

As postmarketOS we care about armv7 yes but so far we have no interest in this particular package. I must say it's the first time I heard of this package 😅

[raymanfx]

Quick heads-up: I am actively working on armv7 support in my crate as we speak and expect to fix these issues myself before long. The next branch [1] compiles fine for 32 bit triplets like armv7-unknown-linux-musleabihf right now and I expect to publish an update to crates.io soon.

Sounds like the issue is resolved, the library is proven to be maintained, issues are being worked on, and we don't know of any better alternative 😉 Thanks to everyone involved, closing!
