The options are live from AVHWaccel.init() to AVHWAccel.uninit(). As such,
they are specific to an active hwaccel and have a meaning to that hwaccel
only during initialization. Options can be initialized by the user during
AVCodecContext.get_format() with hwaccel-specific (public) helper functions.
This is an internal infrastructure change/addition only.
