Hi everyone,
for my Bikefitting App I've implemented a Button to read in a Videofile and display it on an UIAxes. By know, it is possible to start and stop the Video. I'd like to implement two buttons to go forward and rewind frame by frame. Does anyone know how to implement this ?
Here is my Code so far:
function selectn_videoPushed(app, event)
[file, path] = uigetfile('.mp4', 'Bikefitting_rot_.mp4');
if isequal(file, 0)
disp('User selected cancel');
else
disp(['User selected ', fullfile(path,file)]);
app.basicwaitbar;
%Displaying Video on Axes
input_video_file = fullfile(path,file);
app.vidObj = VideoReader(input_video_file);
app.Play_Stop.Visible = 'off';
app.Play_Stop_2.Visible = 'on';
app.frame = readFrame(app.vidObj);
imshow(app.frame, 'Parent', app.UIAxes);
app.BacktoLiveModeButton.Visible = 'on';

This can be accomplished by "timer class" (https://www.mathworks.com/help/matlab/ref/timer-class.html). On each timer event, you can check the pause button to decide if the playing should be paused or not.
