Simplify default values

It makes sense to extract default values for bitrate and port range
(which are arbitrary and might be changed in the future).

However, the default values for "max size" and "lock video orientation"
are naturally unlimited/unlocked, and will never be changed. Extracting
these options just added complexity for no benefit, so hardcode them.
