Re: problem with mplayer?

[Stefan van der Walt]

Hi Agnes

The command "mplayer -vo png myfile.avi" takes myfile.avi and extracts all the 
frames, to files named

0000000*.png

(you can also use -vo jpeg for jpeg etc.)

These files can be loaded individually, by doing

imread('00000001.jpg')

etc.

Regards
Stéfan
