- 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.
