8 查看最终视频构造读者对象。命令行键入：shuttleAvi = VideoReader(fullfile(workingDir,'shuttle_out.avi'));9 从视频帧创建一个MATLAB电影结构。命令行键入：ii = 1;while hasFrame(shuttleAvi) mov(ii) = im2frame(readFrame(shuttleAvi)); ii = ii+1;end 10 根据视频的宽度...
then '.avi' will be used. Use AVIFILE/CLOSE to close the file opened by AVIFILE. Use "clear mex" to close all open AVI files. GETFRAMEGet movie frame. GETFRAME returns a movie frame. The frame is a snapshot of the current axis. GETFRAME is usually used in a FOR loop to assembl...

movie2avi(M,'img2914\out4.avi','compression', 'None','FPS',30)%输出视频 'FPS'为速度参数，后为值，一般是三十帧，迅雷能正常播放
但是这还是不方便,由于它没法脱离MATLAB环境,很讨厌。还好MATLAB为我们提供了movie2avi函数,它可以把动画直接转换成avi文件,而avi文件则可以脱离Matalb环境而在其他地方运行了。 1:保存成avi文件 几个必要的函数: AVIFILECreate a new AVI file AVIOBJ = AVIFILE(FILENAME) creates an AVIFILE object AVIOBJ with...

一、第一个方法比较简单,就是使用movie(f)直接取生成AVI视频文件。 %% f(t)–>f(4t+12) 并且验证%% function Signal_change() tic%记录程序运行时间 figure n = 0; t = -2pi:0.01:2pi; y = sin(t);%周期为2pi y_result = sin(4*t); plot(t,y,‘b... ...
I am trying to use the movie2avi function in MATLAB. I simply copy the sample program in my MATLAB R2015a: nFrames = 20; % Preallocate movie structure. mov(1:nFrames) = struct('cdata', [],... 'colormap', []); % Create movie. ...
