Play Motion JPEG 2000 (.mj2) lossless video
Related: Python Matplotlib lossless video creation
Matlab can create lossless videos from image or plot/figure series from Matlab by EITHER:
- Save PNG image stack, then convert PNG stack to lossless video
- Save from Matlab directly as lossless JPEG2000 .jp2 video (as described below)
Example
This example saves lossless MJPEG2000 .mj2 video plots from Matlab.
v = VideoWriter('test.mj2','Motion JPEG 2000');
v.LosslessCompression = true;
v.FrameRate=5;
open(v)
f=figure;
pause(0.2) % let plot wake up
for i=1:.05:3;
line(0:.01:1,(0:.01:1).^i) % just an example
im = getframe(f);
writeVideo(v,im)
end
close(v)
Play .mj2
This method plays back Motion JPEG 2000 .mj2
files from the command line (outside of Matlab).
- install FFmpeg
- play lossless Motion JPEG 2000 videos:
ffplay movie.mj2
Notes
- Motion JPEG 2000 is the only lossless compressed format available from Matlab.
mmread.m
file enables more Matlab video I/O by using FFmpeg and AVbin via the included compiledFFGrab.mex
file.
