[其他] Webcam以被使用

[wantfly1324 (風飆揚)]

最近在嘗試用MATLAB來使用Webcam來錄製影片
但是在跑MATLAB網站上的程式碼
clear all;
clc;
vid = videoinput('winvideo',1, 'YUY2_320x240');
set(vid, 'FramesPerTrigger', Inf);
set(vid, 'ReturnedColorspace', 'rgb');

vid.FrameGrabInterval = 1;
start(vid)

aviObject = VideoWriter('myVideo.avi');   % Create a new AVI file
for iFrame = 1:100                    % Capture 100 frames


  I=getsnapshot(vid);

  F = im2frame(I);                    % Convert I to a movie frame
  aviObject = addframe(aviObject,F);  % Add the frame to the AVI file
end
aviObject = close(aviObject);         % Close the AVI file
stop(vid);
在跑這個程式碼時，會出現下面這個錯誤
winvideo: The device associated with device ID 1 is already in use.  A
new videoinput object cannot be created for this device while it is in
use.
想請問這要怎麼解決?
