Hi,
I'm using figures creating videos in order to document my processing.
The code runs fine without Parallel Computing Toolbox (PCT).
However, in order to speed up I like to process multiple videos in parallel.
The one and the same code throws the following error using PCT:
MATLAB figure windows are disabled. GETFRAME can not capture any part of a figure's frame, menus, or toolbars unless figure windows are displayed.
Yes, PCT workers process everything in background without visualizing it. Anyway I like to have multiple videos generated in parallel.
The code uses the VideoWriter and getFrame to collect the video.
vidWriter = VideoWriter(['Video' num2str(a(1)) '.avi']);
:
fig = figure;
:
writeVideo(vidWriter, getframe(fig))
How to enable figures even they are called by a PCT worker in background?
Thanks!
