I'll start by saying I don't have insertText so have been using text(). The code I have so far is:
v = VideoReader('1.mp4');
vidWidth = v.Width;
vidHeight = v.Height;
mov = struct('cdata',zeros(vidHeight,vidWidth,3,'uint8'),'colormap',[]);
k = 1;
while hasFrame(v)
mov(k).cdata = readFrame(v);
k = k+1;
end
hf = figure;
set(hf,'position',[150 150 vidWidth vidHeight]);
text(0.5,0.5,'LLLLLLL');
hold on
movie(hf,mov,1,v.FrameRate);
hold off
it seems the text is getting written behind the video and not being added directly to the video. have tried bringing the text to the front in case that was the problem to no avail. does anyone have any ideas?
