	• highest - Selects the highest bitrate content available (default).
	• lowest - Selects the lowest bitrate content available.
	• auto - Automatically adjusts the selected bitrate, based on the connection performance.
	• integer value - Selects a specific content bitrate, in bits per second. The filter will find the closest bitrate to the specified value available.
	_ssf_Language - Selects the preferred language used by the filter. SSF media often contains content for multiple languages.
