OpenCV cvCaptureFromAVI error in Ubuntu 9.04

Recently I have installed Ubuntu Jaunty (v 9.04). I have developed some projects using OpenCV api and I have realized the cvCaptureFromAVI function wasn’t working as expected. At first I thought it had some relation with the video codec, but after converting (in Windows) the video used to an uncompressed video, this was discarded.

Then, I searched the web looking for some kind of information, and finally I found this link: http://ubuntuforums.org/showthread.php?p=7208937 in which the problem is detailed and one really easy sollution is shown.

That solution is posted here by  Gijs Molenaa: http://gijs.pythonic.nl/blog/2009/may/3/getting-video-io-working-opencv-and-ubuntu-jaunty-/

He has solved the problem fixing the sources and compiling them. He has created the .deb files and allocated them in a server. The fix in my laptop has been a piece of cake.

• Modify my /etc/apt/sources.list to add     deb http://ppa.launchpad.net/gijzelaar/opencv/ubuntu jaunty main
• Import the keyserver sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com cafc44ee7f39098ce6ec229cca70e6a9087475a0
  
• apt-get update
• Update the opencv packages

Once the opencv packages has been updated the function works fine.

Thanks a lot to Gijs Molenaa
