Interesting point.

Our library does not define any exceptions, nor does it explicitly throw
any.  So the only exceptions emitted by the library will be divide-by-zero
and other things that indicate bugs that we probably don't want to catch
unless there was a way to report a stack trace or something else useful.

Most users of x265 will not use our CLI wrapper, they will use us as a
library and thus they would need to catch exceptions from our API calls at
whatever level is appropriate to them.
