一、导入AVProMovieCapture包
在Asset Store资源商店里面可以下载这个插件:
https://assetstore.unity.com/packages/tools/video/avpro-movie-capture-desktop-edition-221914
目前这个插件比较贵,以下提供了老一点的版本,也是可以用的。

下载之后解压,并把这个包导入到Unity中,可以看到RenderHeads/AVProMovieCapture
二、屏幕捕捉基本设置
在开始录制Game视图时要对录制做一些基本的设置:
-
输出文件夹类型:输出视频到哪个位置
-
输出子文件夹:输出视频位置的子文件夹
-
分辨率:设置视频的分辨率
-
帧率:设置视频的帧率
-
视频前缀:设置视频名称的前缀
//视频输出路径
public string videoOutFolder;
//视频输出路径类型
public OutputPath outputFolderType = defaultOutputFolderType;
//视频输出文件夹
public string outputFolderPath = defaultOutputFolderPath;//视频降分辨率
public CaptureBase.DownScale downScale = CaptureBase.DownScale.Original;
//视频帧率
public float frame = 60;
//视频前缀
public string prefix = "ScreenCapture";/// <summary>
/// 设置视频输出路径
/// </summary>
private void SetOutFolderPath()
{videoOutFolder = GetFolder(outputFolderType, outputFolderPath);if (!Directory.Exists(videoOutFolder))Directory.CreateDirectory(videoOutFolder);_movieCapture.OutputFolderPath = videoOutFolder;
}/// <summary>
/// 设置视频画质
/// </summary>
private void SetDownScale()
{_movieCapture.ResolutionDownScale = downScale;
}/// <summary>
/// 设置帧率
/// </summary>
private void SetFrameRate()
{_movieCapture.FrameRate = frame;}/// <summary>
/// 设置文件前缀
/// </summary>
private void SetPrefix()
{_movieCapture.FilenamePrefix = prefix;
}
三、实现Game视图屏幕捕捉功能
1、屏幕捕捉功能
在导入包后就可以进行屏幕录制功能开发,包含开始录频、结束录频、查看最近录制,同时在录制的过程中也能够看到当前当前录制视频的大小和时长。
private long _lastFileSize;private uint _lastEncodedMinutes;private uint _lastEncodedSeconds;private uint _lastEncodedFrame;private StringBuilder _fileSize = new StringBuilder();private StringBuilder _videoLength = new StringBuilder();/// <summary>/// 开始录制/// </summary>private void StartCapture(){_lastFileSize = 0;_lastEncodedMinutes = _lastEncodedSeconds = _lastEncodedFrame = 0;if (_movieCapture != null){_movieCapture.StartCapture();startRecord.interactable = false;stopRecord.interactable = true;}}/// <summary>/// 停止录制/// </summary>private void StopCapture(){if (_movieCapture != null){if (_movieCapture.IsCapturing()){_movieCapture.StopCapture();startRecord.interactable = true;stopRecord.interactable = false;}}}/// <summary>/// 文件大小设置/// </summary>/// <param name="lastFileSize"></param>private void FileSize(){_lastFileSize = _movieCapture.GetCaptureFileSize();_fileSize.Clear();_fileSize.Append((_lastFileSize / (1024f * 1024f)).ToString("F1"));_fileSize.Append("MB");}/// <summary>/// 视频长度设置/// </summary>private void VideoLength(){if (!_movieCapture.IsRealTime){_lastEncodedSeconds = (uint)Mathf.FloorToInt(_movieCapture.CaptureStats.NumEncodedFrames / _movieCapture.FrameRate);}else{_lastEncodedSeconds = _movieCapture.CaptureStats.TotalEncodedSeconds;}_lastEncodedMinutes = _lastEncodedSeconds / 60;_lastEncodedSeconds = _lastEncodedSeconds % 60;_lastEncodedFrame = _movieCapture.CaptureStats.NumEncodedFrames % (uint)_movieCapture.FrameRate;_videoLength.Clear();_videoLength.Append(_lastEncodedMinutes.ToString("00"));_videoLength.Append(":");_videoLength.Append(_lastEncodedSeconds.ToString("00"));_videoLength.Append(".");_videoLength.Append(_lastEncodedFrame.ToString("000"));}
- 开始录制: 开始进行Game视图录制
- 结束录制: 结束录制,录制结束后,视频会进进行保存
- 最新录制: 显示最近录制的视频记录
- File Size: 当前录制视频的文件大小
- Video Length: 当前录制视频的时长
2、视频列表功能
在视频录制完成后,会将视频信息进行保存,当点击最新录制会显示视频列表窗口,在这里你可以找到所有的最近录制的视频记录。
public class RecordList : MonoBehaviour
{public RecordItem recordItemPre;private List<RecordItem> records = new List<RecordItem>();/// <summary>/// 初始化记录表/// </summary>/// <param name="saveInfos"></param>public void InitRecordList(List<VideoInfo> videoList){gameObject.SetActive(true);for (int i = 0; i < records.Count; i++){Destroy(records[i].gameObject);}records.Clear();for (int i = 0; i < videoList.Count; i++){RecordItem recordItem = Instantiate(recordItemPre, recordItemPre.transform.parent);recordItem.InitRecordItem(videoList[i]);records.Add(recordItem);recordItem.gameObject.SetActive(true);}}
}
public class RecordItem : MonoBehaviour{public Text videoName;public Text videoSize;public Text videoLength;public Text lastModifyTime;public Button view;public VideoControl videoControl;private VideoInfo videoInfo;// Start is called before the first frame updatevoid Start(){view.onClick.AddListener(() => {videoControl.VideoControlInit(videoInfo.videoPath);});}/// <summary>/// 初始化记录表/// </summary>/// <param name="saveInfo"></param>public void InitRecordItem(VideoInfo videoInfo){this.videoInfo = videoInfo;videoName.text = videoInfo.videoName;videoSize.text = (videoInfo.videoSize / (1024f * 1024f)).ToString("F1") + "MB";videoLength.text = (videoInfo.videoLength / 60).ToString("00") + ":" + (videoInfo.videoLength % 60).ToString("00");lastModifyTime.text = videoInfo.lastModifyTime;}}
- 名称: 视频名称
- 大小: 视频文件大小
- 时长: 视频时长
- 最后修改: 视频保存时间
- 查看: 播放视频
3、视频播放功能
在视频列表中,点击查看按钮就可以播放该视频。
public class VideoControl : MonoBehaviour
{public Text title;public VideoPlayer player;public Slider videoSlider;public Button close;public Text videotime;public Text videoLength;string videoPath;private void Update(){if (player.isPlaying){SetCurPlayTime();SetPlaySchedule();}}private void Awake(){player.prepareCompleted += OnPrepareCompleted;}private void OnDestroy(){player.prepareCompleted -= OnPrepareCompleted;}public void VideoControlInit(string videoPath){this.videoPath = videoPath;gameObject.SetActive(true);SetVideoPlayPath(videoPath);PlayVideo();}/// <summary>/// 视频准备/// </summary>/// <param name="videoSource"></param>private void OnPrepareCompleted(VideoPlayer videoSource){SetVideoName();SetVideoLength();}/// <summary>/// 设置视频名称/// </summary>private void SetVideoName(){title.text = Path.GetFileNameWithoutExtension(videoPath);}/// <summary>/// 设置播放器路径/// </summary>/// <param name="path"></param>public void SetVideoPlayPath(string path){player.url = path;}/// <summary>/// 当前视频播放时间/// </summary>private void SetCurPlayTime(){videotime.text = TimeProcess(player.time);}/// <summary>/// 设置视频时长/// </summary>/// <param name="length"></param>private void SetVideoLength(){videoLength.text = TimeProcess(player.length);}/// <summary>/// 设置播放进度/// </summary>private void SetPlaySchedule(){videoSlider.value = (float)player.frame / player.frameCount;}/// <summary>/// 时间处理/// </summary>/// <param name="time"></param>/// <returns></returns>private string TimeProcess(double time){int minutes = (int)time / 60;int seconds = (int)time % 60;return minutes.ToString("00") + ":" + seconds.ToString("00");}/// <summary>/// 视频播放/// </summary>public void PlayVideo(){player.Play();}
}
视频播放时,会显示视频名称、时长、当前时间和播放进度
