* Moving registration of video methods in Video.cpp and removing unnecessary includes.

* Rename files according to cpp styles.

* Adding namespaces and moving private methods to anonymous namespaces.

* Syncing method names.

* Fixing minor issues.

The video reader suppressed code 61 (ENODATA on Linux) that occured at
the end of a stream and logged an INFO message. On macOS ENODATA has a
different code (96), which resulted in an error message being logged.

This small patch replaces the hard-coded value with the ENODATA constant
to suppress the macOS warning.
