Crate s4m_media_packager 

Media Packager Library

A trait-based library for fragmenting and packaging multi-resolution MP4 files into DASH/HLS formats using FFmpeg and Bento4.

Features

• Parallel demuxing with FFmpeg
• Parallel fragmentation with Bento4 (mp4fragment)
• DASH/HLS packaging with Bento4 (mp4dash)
• Configurable naming templates
• Automatic temporary file management
• One-time runtime binary checks with helpful error messages
• Comprehensive tracing and logging

Example

use std::path::PathBuf;

use s4m_media_packager::{LogConfig, MediaPipeline, MediaPipelineConfig, init_tracing};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize tracing
    init_tracing(LogConfig::development())?;

    let pipeline = MediaPipeline::new()?;
    let inputs = vec![
        PathBuf::from("video_270p.mp4"),
        PathBuf::from("video_720p.mp4"),
    ];
    let config = MediaPipelineConfig::default();
    let output_dir = PathBuf::from("./output");

    let result = pipeline.execute(inputs, config, output_dir).await?;
    println!("Packaged to: {:?}", result.output_dir);
    Ok(())
}
