Play Motion JPEG 2000 .mj2 lossless video
Matlab or GNU Octave can create lossless videos from image stacks or figure series by either:
- Save PNG image stack, then losslessly convert PNG stack to video
- Save from Matlab directly as lossless JPEG2000 video
This example saves lossless MJPEG2000 .mj2 video plots directly from Matlab VideoWriter.
v = VideoWriter('test.mj2', 'Archival');
v.LosslessCompression = true;
v.FrameRate = 5; % arbitrary
open(v)
f = figure;
% or axes
pause(0.2)
% let plot initially draw
for i = 1:.05:3;
line(0:.01:1, (0:.01:1).^i)
% dummy plot sequence
v.writeVideo(getframe(f))
end
close(v)
Play Motion JPEG 2000 .mj2 with FFmpeg from the command line (outside of Matlab):
ffplay movie.mj2
GNU Octave video package also has a “VideoWriter” function.
