HLS options

--hls_master_playlist_output <file_path>
	Output path for the master playlist for HLS. This flag must be used to output HLS.
--hls_base_url <url>
	The base URL for the Media Playlists and media files listed in the playlists. This is the prefix for the files.
--hls_key_uri <uri>
	The key uri for ‘identity’ and ‘com.apple.streamingkeydelivery’ (FairPlay) key formats. Ignored if the playlist is not encrypted or not using the above key formats.
--hls_playlist_type <type>
	VOD, EVENT, or LIVE. This defines the EXT-X-PLAYLIST-TYPE in the HLS specification. For hls_playlist_type of LIVE, EXT-X-PLAYLIST-TYPE tag is omitted.
--time_shift_buffer_depth <seconds>
	Guaranteed duration of the time shifting buffer for LIVE playlists, in seconds.
--preserved_segments_outside_live_window <num_segments>
	Segments outside the live window (defined by time_shift_buffer_depth above) are automatically removed except for the most recent X segments defined by this parameter. This is needed to accommodate latencies in various stages of content serving pipeline, so that the segments stay accessible as they may still be accessed by the player. The segments are not removed if the value is zero.
--default_language <language>
	The first audio/text rendition in a group tagged with this language will have ‘DEFAULT’ attribute set to ‘YES’. This allows the player to choose the correct default language for the content.
