pg如何播放MP4

pg如何播放MP4

1. 使用matlab将mp4解成一张张图片

xyloObj = VideoReader('D:\PythonProject\XXX\resources\global.mp4');
nFrames = xyloObj.NumberOfFrames;
vidHeight = xyloObj.Height;
vidWidth = xyloObj.Width;

for k = 1 : nFrames
    im = read(xyloObj, k);%读取第k帧，存入im中
    imwrite(im, ['D:\PythonProject\XXX\resources\g\original_frame',num2str(k),'.jpg'], 'bmp');%把im存储成图片，并且存储的文件名根据序号改变
end

2. 使用imagej，打包成tif

直接save as即可

 

3.Python code如下

self.projectVideoPath = './resources/project.tif'

self.tifProjectVideo = tifffile.imread(self.projectVideoPath)

self.gViewProjectVideo.setImage(self.tifProjectVideo, xvals=np.linspace(1., 10., self.tifProjectVideo.shape[0]),
                             axes={'t': 0, 'x': 2, 'y': 1, 'c':3})
