An example illustrating transcoding a video in Unity using NatExtractor and NatCorder.

TranscodeDemo.cs

using UnityEngine;
using NatCorder;
using NatExtractor;

public class TranscodeDemo : MonoBehaviour {
    
    public string videoPath; // Path to video to be transcoded
    
    void Start () {
        // Create a frame extractor
        var extractor = new FrameExtractor(videoPath);
        // Create an MP4 recorder
        var recorder = new MP4Recorder(
            extractor.resolution.width,
            extractor.resolution.height,
            extractor.resolution.refreshRate,
            0,
            0,
            OnTranscode
        );
        // Transcode
        extractor.Extract(
            (pixelBuffer, timestamp) => recorder.CommitFrame(pixelBuffer, timestamp),
            () => recorder.Dispose()
        );
    }
    
    void OnTranscode (string path) {
        // Use transcoded video
        ...
    }
}
