veo
veo is a Rust crate designed for efficient and reliable video processing and manipulation tasks. It provides a set of tools for encoding, decoding, and transforming video data within Rust applications.
Installation
To integrate veo into your project, add the following line to your Cargo.toml file under the [dependencies] section:
toml
veo = "0.1.0" # Replace with the latest version
Usage Examples
Here are a few examples demonstrating how to use veo for common video processing tasks:
1. Basic Video Encoding:
This example demonstrates encoding a sequence of images into a video file. rust use veo::encoder::Encoder; use veo::format::VideoFormat;
fn main() -> Result<(), Box> { let mut encoder = Encoder::new("output.mp4", VideoFormat::MP4, 1280, 720, 30)?;
// Assuming you have image data in `image_data` (e.g., Vec<u8>)
// and image dimensions are 1280x720
// Simulate adding frames (replace with actual image data)
for frame_number in 0..100 {
let image_data = vec![0u8; 1280 * 720 * 3]; // Placeholder for image data
encoder.encode_frame(&image_data)?;
}
encoder.finish()?;
println!("Video encoding complete!");
Ok(())
}
2. Video Decoding and Frame Extraction:
This example demonstrates decoding a video file and extracting individual frames. rust use veo::decoder::Decoder; use std::fs::File; use std::io::BufReader;
fn main() -> Result<(), Box> { let file = File::open("input.mp4")?; let reader = BufReader::new(file); let mut decoder = Decoder::new(reader)?;
while let Some(frame) = decoder.decode_frame()? {
// Process the frame data (e.g., save it as an image)
// frame is a Vec<u8> containing the raw pixel data
println!("Decoded frame with size: {}", frame.len());
// Implement your frame processing logic here
}
println!("Video decoding complete!");
Ok(())
}
3. Resizing a Video:
This example illustrates how to resize video frames during encoding. (Note: resizing functionality might require additional feature flags or helper functions, depending on the crate's specific implementation. The example shows the intended usage.) rust use veo::encoder::Encoder; use veo::format::VideoFormat; // Assuming you have a resize function or module. // use veo::resize; // Uncomment if a resize module exists
fn main() -> Result<(), Box> { let mut encoder = Encoder::new("resized_output.mp4", VideoFormat::MP4, 640, 480, 30)?;
// Simulate adding frames (replace with actual image data and resizing)
for frame_number in 0..100 {
let original_image_data = vec![0u8; 1280 * 720 * 3]; // Placeholder for original image data
// Assuming `resize::resize_frame` is a function that resizes the frame
// let resized_image_data = resize::resize_frame(&original_image_data, 1280, 720, 640, 480)?;
let resized_image_data = vec![0u8; 640 * 480 * 3]; // Placeholder for resized image data
encoder.encode_frame(&resized_image_data)?;
}
encoder.finish()?;
println!("Video encoding with resizing complete!");
Ok(())
}
4. Changing Frame Rate:
This example shows how to adjust the frame rate of a video during encoding. (Note: This functionality might require specific encoder settings.) rust use veo::encoder::Encoder; use veo::format::VideoFormat;
fn main() -> Result<(), Box> { let mut encoder = Encoder::new("framerate_output.mp4", VideoFormat::MP4, 1280, 720, 60)?; // Encode at 60 FPS
// Simulate adding frames (replace with actual image data)
for frame_number in 0..50 { // Fewer frames to keep video length similar
let image_data = vec![0u8; 1280 * 720 * 3]; // Placeholder for image data
encoder.encode_frame(&image_data)?;
}
encoder.finish()?;
println!("Video encoding with modified frame rate complete!");
Ok(())
}
Feature Summary
veo offers the following key features:
- Encoding: Supports encoding video data into various formats (e.g., MP4).
- Decoding: Enables decoding of video files to extract raw frame data.
- Format Support: Provides support for common video formats.
- Frame Manipulation: Functionality for manipulating individual video frames (resizing, etc.).
- Cross-Platform Compatibility: Designed to work across different operating systems.
- Error Handling: Robust error handling for reliable video processing.
