oli-obk / camera_capture

Crate for capturing images from a webcam

Webcam capturing in Rust

Description

Captures webcam images and offers access to them through an iterator. Works with v4l2 on Linux. OSX is not supported.

TODO

• threaded access through channel Receiver
• automatic webcam detection and selection

Documentation

You can create the documentation (locally) by executing cargo doc --no-deps --open.

Example

extern crate camera_capture;

fn main() {
    let cam = camera_capture::create(0).unwrap();
    let cam = cam.fps(5.0).unwrap().start().unwrap();
    for _image in cam {
        println!("frame");
    }
    println!("done");
}

Piston Example

• run via cargo run --example piston
• source

camera_capture's Issues

Add appveyor

can you document your pkg-config

On fedora26 the entry for pkg-config isn't automatically populated with package information. So some additional docs in how to link libv4l2 would be helpful.

Give install instructions for all platforms

and mention that osx isn't working yet

examples don't compile

It's a dependency problem with piston:
error: Could not compile `piston2d-gfx_graphics`.
It's 72 times the same error:
Use of undeclared type or module `gfx`

Exact command to reproduce:
cargo run --release --example hello_camera
My system is an Ubuntu x86_64 with libv4l-dev installed and a webcam which is known to work with other programs.

check whether all platforms produce the same API

• Send/Sync missing on windows

examples are failing

Hi there,

i tried the examples and got the following results:

• cargo run --example glium: "An error occured: Webcam thread was killed or did not responded for 500ms. Stopping."
• cargo run --example hello_camera: "thread 'main' panicked at 'called Result::unwrap() on an Err value: InvalidFps([0.0, 0.0])', src/libcore/result.rs:997:5" (looks like #18)
• cargo run --example take_picture: "thread 'main' panicked at 'called Result::unwrap() on an Err value: InvalidFps([0.0, 0.0])', src/libcore/result.rs:997:5" (also looks like #18)

Cheers,

Is this crate supposed to work with MacOS?

The source only distinguishes between unix and windows and for unix, rscam is used. But this is just a wrapper around v4l2 which seems to not exist for MacOS?

panic in piston example

Hi there,

the piston example panics when executed.
thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: InvalidFps([0.0, 0.0])', src/libcore/result.rs:997:5 note: Run with `RUST_BACKTRACE=1` environment variable to display a backtrace.
The offending line seems to be imgthread.join().unwrap();. Note that #17 is related but does not fix this panic.

Cheers,

Fix piston example

Does it work for FullHD 30 fps MJPEG webcam?

Does it work for FullHD 30 fps MJPEG webcam?

My webcam's default capture option is YUV at 5 fps, the only other option is 30 fps as MJPEG. When I use escapi it always chooses the 5 fps because it's the default.
Does this crate support choosing the non-default 30 fps with mjpeg? :)

Does it work at least on linux?

Inaproriate ioctl for device - raspberry pi module 3

Steps to reproduce

fn main() {
    let cam = camera_capture::create(0).unwrap();
    let cam = cam
        .start().expect("Couldn't start");
    for _image in cam {
        println!("frame");
    }
    println!("done");
}

# On a raspberry pi with a camera module 3 connected
cargo run

Expected result

It should print out "frame".

Actual result

thread 'main' panicked at src/main.rs:25:18:
Couldn't start: Os { code: 25, kind: Uncategorized, message: "Inappropriate ioctl for device" }

CouldNotLoadEscapiDLL

CouldNotLoadEscapiDLL(126) shows up when running your example from the readme. The program does work if I get the escapi.dll and put it in the same folder as the exe, however I only want to have one file. Is it possible to inject the escapi.dll inside of the exe with rust?
