我正在使用2013a版本的matlab和windows xp。当我运行videoreader的代码时,我得到了这个错误。那么需要安装什么类型的编解码器。
obj.reader = vision.VideoFileReader('first.avi');
obj.videoPlayer = vision.VideoPlayer();
obj.maskPlayer = vision.VideoPlayer();
obj.detector = vision.ForegroundDetector('NumGaussians', 3, 'NumTrainingFrames', 40, 'MinimumBackgroundRatio', 0.7);
obj.blobAnalyser = vision.BlobAnalysis('BoundingBoxOutputPort', true,'AreaOutputPort', true, 'CentroidOutputPort', true,'MinimumBlobArea', 400);
