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?

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.

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)

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?

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.

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" }

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?

and mention that osx isn't working yet

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.
