如何在vector <mat>中保存一些摄像机帧，然后在JavaCameraView中播放？

Question

我正在使用Android Studio，OpenCV和JavaCameraView来显示相机的框架。我想创建一个简单的Mat帧记录器。例如，我要保存100个最后一帧，然后在JavaCameraView中显示它。

我记录了矢量用于存储Mat帧的CameraFrames。在功能onCameraFrame中，我有...

@Override
public Mat onCameraFrame(CameraBridgeViewBase.CvCameraViewFrame cameraFrame) {

colorMat = cameraFrame.rgba();

if(frameCountForRecording < 100){
    recordedCameraFrames.add(colorMat);
    frameCountForRecording++;
}       
else {
    isRecordedFramesReadyToPlay = true;
    recordedCameraFrames.remove(0);
    recordedCameraFrames.add(colorMat);
}

然后当我激活PLAY_DETECTED_FRAMES_VIEW_MODE时，我要播放录制的帧...

case PLAY_DETECTED_FRAMES_VIEW_MODE:

if(isRecordedFramesReadyToPlay == true && canPlayRecordedFrames == true) {
        if (indexOfRecordedFrame == 99) {
              indexOfRecordedFrame = 0;
        }
        indexOfRecordedFrame++;
        colorMat = recordedCameraFrames.get(indexOfRecordedFrame).clone();
}
break;
