  MODULE: OB_AVI.H:  declarations for the AVI-Player-Object
  Author: Chris Veigl

  This Object can open a standard avi-file, grab a frame 
  and display it in a sizeable window. the frame number is given to the object's 
  input port. Sound of the AVI-File is not processed.

  Inspired by   Jeff Molofee's Lesson 35: Playing AVI-Files with OpenGl
