How to synchronize playback and recording with the Vimeo Unity SDK.

SyncRecorderAndPlayer.cs

using UnityEngine;
using Vimeo.Recorder;
using Vimeo.Player;
using System.Collections;

namespace Vimeo.Recorder 
{
    public class SyncRecorderAndPlayer : MonoBehaviour {
        private VimeoRecorder recorder;
        public VimeoPlayer vimeoPlayer;
        public bool syncDuration = false;

        void Awake()
        {
            vimeoPlayer.OnVideoStart += VideoStart;
        }

        void Start() 
        {
            recorder = gameObject.GetComponent<VimeoRecorder>();
            recorder.defaultVideoInput = Vimeo.Recorder.VideoInputType.Screen;		
            recorder.frameRate = 30;
            recorder.realTime = false;
        }

        void VideoStart()
        {
            recorder.videoName = vimeoPlayer.videoName + " (Tiny Planet)";

            // Setup the video controller to inform us when a new frame is being displayed
            vimeoPlayer.controller.SendFrameReadyEvents();
            vimeoPlayer.controller.EnableFrameStepping();
            vimeoPlayer.controller.OnFrameReady += FrameReady; 

            // Sync the frame rate and record duration to the video. Not necessary, but nice to have
            recorder.frameRate = (int)vimeoPlayer.controller.videoPlayer.frameRate;

            if (syncDuration) {
                recorder.recordMode     = Vimeo.Recorder.RecordMode.Duration;
                recorder.recordDuration = vimeoPlayer.controller.GetDuration(); 
            }

            // This method is used specifically for letting us trigger when we want to capture
            recorder.BeginManualRecording(); 
        }

        void FrameReady(VideoController controller)
        {
            // When the frame is ready, we will manually trigger the recorder to capture the frame
            StartCoroutine(RecordFrame());
        }

        IEnumerator RecordFrame()
        {
            yield return new WaitForEndOfFrame();
            recorder.encoder.AddFrame();	
        }
        
        void OnDisable()
        {
            if (vimeoPlayer != null) {
                vimeoPlayer.controller.OnFrameReady -= FrameReady; 
            }
        }
    }
