function screen_capture(movie_name,recording_time) %Can be used to record any screen activity and output %the recorded actions as video file (MOVIE.avi). It also saves the frames used to %create the movie in a jpg format frames. The images are named as %scrcapture -frame number- .jpg %For example the first frame is named scrcapture1.jpg %The recording time is almost identical to the actual cpu time. %The quality of the video is excellent, but the size is big. One is advised %to record short videos(order of minutes).For even better quality, one could replace the % png format to jpg(simply uncomment the respective commands). % to call the function, one types: % % screen_capture(movie_name,recording_time) % where % movie_name: is a string representing the name of the movie % recording_time: is the length of the capturing (in seconds) %To try, one might use the following example: % screen_capture('movie',30) %When the code is done writing the movie, a gong sound will be played %to inform the user that the movie is finished. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %This function is written by : % Nassim Khaled % Wayne State University % Phd Candidate %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% movie_name1=strcat(movie_name,'.avi') mov = avifile(movie_name1); count=0; robo = java.awt.Robot; t = java.awt.Toolkit.getDefaultToolkit(); rectangle = java.awt.Rectangle(t.getScreenSize()); number_of_frames=round(recording_time/0.65); display_time_of_frame=10; for i=1:number_of_frames name1=strcat('scrcapture',num2str(i),'.png'); % name1=strcat('scrcapture',num2str(i),'.jpg'); image = robo.createScreenCapture(rectangle); filehandle = java.io.File(name1); javax.imageio.ImageIO.write(image,'png',filehandle); % javax.imageio.ImageIO.write(image,'jpg',filehandle); end for i=1:number_of_frames name1=strcat('scrcapture',num2str(i),'.png'); % name1=strcat('scrcapture',num2str(i),'.jpg'); a=imread(name1); while count<display_time_of_frame count=count+1; F = im2frame(a); mov=addframe(mov,F); end count=0; end close all mov=close(mov); load gong; wavplay(y,Fs)
