WAIT timeout on image acquisition toolbox

Hi, I would like to record a video for 5 min using Image acquisition toolbox. I got the error "WAIT reached its timeout before OBJ stopped running." If I remove wait(v), video is not acquired. Could anyone please advise? thanks.

v = videoinput("gentl", 1, "Mono8");
filelocation = "D:\test\mouse 1";
filename = "recording4.mp4";
fullFilename = fullfile(filelocation, filename);

% Create and configure the video writer
logfile = VideoWriter(fullFilename, "MPEG-4");
logfile.FrameRate = 10;


% Configure the device to log to disk using the video writer
v.LoggingMode = "disk";
v.DiskLogger = logfile;
% v.ROIPosition = [0 300 1920 400];

durationinmin = 5;
numFrames = logfile.FrameRate * 60 * durationinmin;
v.FramesPerTrigger = numFrames;

start(v);
% set(v, 'Timeout', 600);
wait(v);
stop(v);

% Wait for all frames to be written to disk
while v.FramesAcquired ~= v.DiskLoggerFrameCount
    pause(.1);
end

delete(v)
clear v

Hi @AT_HYZ,

Could you try uncommenting the set() line that changes the timeout for v? That will set the timeout to 600 seconds (10 minutes) and should allow the wait(v) to run through without exhausting the timeout. The default timeout is 10 seconds, which is not enough time to capture the 5-minute video. Please see this resource for more information: Create video input object - MATLAB - MathWorks India.

I tried uncommenting th set() line and error showed "Timeout: the property cannot be set while Running is set to "on"" .... how can I solve it? thanks.

I put it after "v = videoinput("gentl", 1, "Mono8");" and it works.
