Is there a way to force opencv to use the latest version ? I tried uninstalling ffmpeg, reinstalling and rebuilding CV but it keeps finding the older version

Two things you should do

  1. Run cmake-gui in the build folder and see if you can explicitly link to the correct folders using the options provided.
  2. Before that, make sure that this folder is gone from your installation. It first looks there and installs that one if it can.

1) Building it on ubuntu server so using command line. Would rather not use gui. 2) The folder 3rdpart/ffmpeg does not exist in the version of CV3.0 I got from web.

Hmm that is sketchy. I always use a download from the official github repo if I build OpenCV myself. I suggest you to do the same, because else problems can be occuring due to much different reasons. You could run a gui locally to see which parameters need to be set explicitly, then add them to your CMAKE make command in the terminal.
