brandtr bea36fdee8 Minor improvements to VideoProcessor and corresponding test.
- Make all overridden methods of VideoProcessorImpl public,
  in preparation of the removal of the VideoProcessor interface.
- Place corresponding method definitions in correct order
  in .cc file.
- Harmonize the stdout printing.
- Make timestamp calculations adhere to set frame rate.

Except for the last bullet, these changes should not lead to
different functionality.
