lightweight cross-platform camera capture library with hardware-accelerated pixel format conversion. + +## Features + +- **High Performance**: Hardware-accelerated pixel format conversion with up to 10x speedup (AVX2, Apple Accelerate, NEON) +- **Cross Platform**: Windows (DirectShow), macOS/iOS (AVFoundation), Linux (V4L2) +- **Multiple Formats**: RGB, BGR, YUV (NV12/I420) with automatic conversion +- **Zero Dependencies**: Uses only system frameworks +- **Memory Safe**: Safe Rust API with automatic resource management +- **Async Support**: Optional async/await interface with tokio +- **Thread Safe**: Safe concurrent access to video frames + +## Quick Start + +Add this to your `Cargo.toml`: + +```toml +[dependencies] +ccap = "1.1.0" + +# For async support +ccap = { version = "1.1.0", features = ["async"] } +``` + +### Basic Usage + +```rust +use ccap::{Provider, Result}; + +fn main() -> Result<()> { + // Create a camera provider + let mut provider = Provider::new()?; + + // Find available cameras + let devices = provider.find_device_names()?; + println!("Found {} cameras:", devices.len()); + for (i, device) in devices.iter().enumerate() { + println!(" [{}] {}", i, device); + } + + // Open the first camera + if !devices.is_empty() { + provider.open(Some(&devices[0]), true)?; + println!("Camera opened successfully!"); + + // Capture a frame + if let Some(frame) = provider.grab_frame_blocking()? { + let info = frame.info()?; + println!("Captured frame: {}x{}, format: {:?}", + info.width, info.height, info.pixel_format); + + // Access frame data + let data = frame.data()?; + println!("Frame data size: {} bytes", data.len()); + } + } + + Ok(()) +} +``` + +### Async Usage + +```rust +use ccap::r#async::AsyncProvider; + +#[tokio::main] +async fn main() -> ccap::Result<()> { + let provider = AsyncProvider::new().await?; + let devices = provider.find_device_names().await?; + + if !devices.is_empty() { + provider.open(Some(&devices[0]), true).await?; + + // Async frame capture + if let Some(frame) = provider.grab_frame().await? { + let info = frame.info()?; + println!("Async captured: {}x{}", info.width, info.height); + } + } + + Ok(()) +} +``` + +## Examples + +The crate includes several examples: + +```bash +# List available cameras +cargo run --example list_cameras + +# Capture frames synchronously +cargo run --example capture_frames + +# Capture frames asynchronously (requires async feature) +cargo run --features async --example async_capture +``` + +## Building + +### Prerequisites + +Before building the Rust bindings, you need to build the ccap C library: + +```bash +# From the root of the CameraCapture project +./scripts/build_and_install.sh +``` + +Or manually: + +```bash +mkdir -p build/Debug +cd build/Debug +cmake ../.. -DCMAKE_BUILD_TYPE=Debug +make -j$(nproc) +``` + +### Building the Rust Crate + +```bash +# From bindings/rust directory +cargo build +cargo test +``` + +## API Documentation + +### Core Types + +- `Provider`: Main camera capture interface +- `VideoFrame`: Represents a captured video frame +- `DeviceInfo`: Camera device information +- `PixelFormat`: Supported pixel formats (RGB24, BGR24, NV12, I420, etc.) +- `Resolution`: Frame resolution specification + +### Error Handling + +All operations return `Result` for comprehensive error handling: + +```rust +match provider.grab_frame_blocking() { + Ok(Some(frame)) => { /* process frame */ }, + Ok(None) => println!("No frame available"), + Err(e) => eprintln!("Capture error: {:?}", e), +} +``` + +### Thread Safety + +- `VideoFrame` is `Send + Sync` and can be safely shared between threads +- `Provider` should be used from a single thread or protected with synchronization +- Frame data remains valid until the `VideoFrame` is dropped + +## Platform Support + +| Platform | Backend | Status | +|----------|---------|---------| +| Windows | DirectShow | ✅ Supported | +| macOS | AVFoundation | ✅ Supported | +| iOS | AVFoundation | ✅ Supported | +| Linux | V4L2 | ✅ Supported | + +## System Requirements + +- Rust 1.65+ +- CMake 3.14+ +- Platform-specific camera frameworks (automatically linked) + +## Contributing + +Contributions

Add GitHub Actions workflow permissions (contents: read) - Fix memory leak in Provider callback management - Add callback_ptr field to track callback lifecycle - Implement cleanup_callback() method - Clean up callbacks in Drop implementation - Fix open_device ignoring device_name parameter - Fix pixel format conversion type errors in set/get operations - Fix VideoFrame data plane size calculations - Plane 0: stride * height - Chroma planes: stride * (height + 1) / 2 Important fixes: - Remove strict device count assertion in tests - Add bounds checking for DeviceInfo arrays - Fix README example code - Use open_device() instead of open() - Use grab_frame(timeout) instead of grab_frame_blocking() Minor fixes: - Add ConversionFailed error variant - Clean up unused imports in utils.rs - Document AsyncProvider's reserved _frame_sender field -
