The Auto level lets the encoder decide which level to use.
Furthermore, some devices allow levels beyond 4.2. Therefore,
we add all levels allowed by H.264. This is of importance,
since using a resolution not supported by the specified level
can trigger undefined behavior on the hardware/kernel.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
