python script for convert video to image sequence using FFmpeg

you can use ffmpeg to convert the video to sgi images using this ffmpeg command

ffmpeg -i inputVideo outputFrames_%04d.sgi

-replace inputVideo your input file path and name

-replace outputFrames with output file path and name

-replace '4' in _%04d with the number of digits you want for sequential image file naming.

now one way to process your files from python is to launch ffmpeg as a subprocess and providing the command you want executed by ffmpeg:

import subprocess as sp
cmd='ffmpeg -i inputVideo outputFrames_%04d.sgi'
sp.call(cmd,shell=True)

remember to use double \ in your file path in the cmd command string (at least for me on windows). If you want to loop over 100 movie files, write a loop that concatenates the command string with the appropriate input and output file names.
