Rust wrapper for v4l2.
```rust let mut camera = rscam::new("/dev/video0").unwrap();
camera.start(&rscam::Config { interval: (1, 30), // 30 fps. resolution: (1280, 720), format: b"MJPG", ..Default::default() }).unwrap();
for i in 0..10 { let frame = camera.capture().unwrap(); let mut file = fs::File::create(&format!("frame-{}.jpg", i)).unwrap(); file.write_all(&frame[..]).unwrap(); } ```
The wrapper uses v4l2 (e.g. v4l2_ioctl()
instead of ioctl()
) until feature no_wrapper
is enabled. The feature can be useful when it's desirable to avoid dependence on libv4l2 (for example, cross-compilation).
