Change default port options for ffmpeg

[Dries Michiels]

Dear Multimedia Mailing List,

With the increasing popularity of emby-server.
Is it possible to change the default port options of ffmpeg to be compatible with emby-server.

https://emby.media/freebsd-server.html

As can be seen from the URL, some port options need be enabled to provide full functionality for emby-server.
However, maybe not all options are as critical to be enabled (such as SBM, why is it used? Or not?), food for though.

With regards,
Dries
