Fix libav/ffmpeg compilation: Use 'dot less' dir/file names; Compile ffmpeg version dependent c-files individually and inject object files. ; ffmpeg *register_all() at setStream0(..)

- Use 'dot less' dir/file names

- Compile ffmpeg version dependent c-files individually and inject object files.

- ffmpeg *register_all() at setStream0(..)
  - Only register devices if available _and_ camera is requested.
