I have all the codecs to read the video I want to process using OpenCV.</P> <P>Does anyone has experienced the same problem and found a solution? Any help will be greatly appreciated!</P> <P></P> <P>OK a fresh update:</P> <P>I converted a movie using</P> <P>mencoder cat1.mpg -nosound -ovc raw -vf format=i420 -o out.avi</P> <P>and this works, I can launch the cam-histo.py sample with the out.avi file...
