New Extra Argument Parameters
Added two new parameters for passing additional arguments to ffmpeg and x265. See the README or help-based comments for full details.
What's New
-FFMpegExtra
You can now pass raw arguments directly to ffmpeg through this parameter. It receives a generic array, and can accept single values (for options that receive no arguments) and/or a multi-valued hashtable (for options that receive arguments).
-x265Extra
You can now pass additional arguments directly to the x265 encoder through this parameter. It receives a hashtable of values as input, because all x265 arguments have a value (even if it's 1 or 0 for 'on' and 'off'').
