Constructor & Destructor Documentation

shaka::hls::SimpleHlsNotifier::SimpleHlsNotifier	(	HlsPlaylistType	playlist_type,
		double	time_shift_buffer_depth,
		const std::string &	prefix,
		const std::string &	key_uri,
		const std::string &	output_dir,
		const std::string &	master_playlist_name
	)

prefix is used as hte prefix for all the URIs for Media Playlist. This includes the segment URIs in the Media Playlists.

Parameters

playlist_type	is the type of the playlists.
time_shift_buffer_depth	determines the duration of the time shifting buffer, only for live HLS.
prefix	is the used as the prefix for MediaPlaylist URIs. May be empty for relative URI from the playlist.
key_uri	defines the key uri for "identity" and "com.apple.streamingkeydelivery" key formats. Ignored if the playlist is not encrypted or not using the above key formats.
output_dir	is the output directory of the playlists. May be empty to write to current directory.
master_playlist_name	is the name of the master playlist.

Member Function Documentation

bool shaka::hls::SimpleHlsNotifier::Flush ( )

overridevirtual

Process any current buffered states/resources.

Returns: true on success, false otherwise.

Implements shaka::hls::HlsNotifier.

Definition at line 435 of file simple_hls_notifier.cc.

bool shaka::hls::SimpleHlsNotifier::Init ( )

overridevirtual

Intialize the notifier.

Returns: true on sucess, false otherwise.

Implements shaka::hls::HlsNotifier.

Definition at line 266 of file simple_hls_notifier.cc.

bool shaka::hls::SimpleHlsNotifier::NotifyEncryptionUpdate	(	uint32_t	stream_id,
		const std::vector< uint8_t > &	key_id,
		const std::vector< uint8_t > &	system_id,
		const std::vector< uint8_t > &	iv,
		const std::vector< uint8_t > &	protection_system_specific_data
	)

overridevirtual

Parameters

stream_id	is the value set by NotifyNewStream().
key_id	is the key ID for the stream.
system_id	is the DRM system ID in e.g. PSSH boxes. For example this can be used to determine the KEYFORMAT attribute for EXT-X-KEY.
iv	is the new initialization vector.
protection_system_specific_data	is the DRM specific data. The interpretation of this data is up to the implementation, possibly using system_id to determine how to interpret the data.

bool shaka::hls::SimpleHlsNotifier::NotifyNewSegment	(	uint32_t	stream_id,
		const std::string &	segment_name,
		uint64_t	start_time,
		uint64_t	duration,
		uint64_t	start_byte_offset,
		uint64_t	size
	)

overridevirtual

Parameters

stream_id	is the value set by NotifyNewStream().
segment_name	is the name of the new segment.
start_time	is the start time of the segment in timescale units passed in media_info.
duration	is also in terms of timescale.
start_byte_offset	is the offset of where the subsegment starts. This should be 0 if the whole segment is a subsegment.
size	is the size in bytes.

Implements shaka::hls::HlsNotifier.

bool shaka::hls::SimpleHlsNotifier::NotifyNewStream	(	const MediaInfo &	media_info,
		const std::string &	playlist_name,
		const std::string &	stream_name,
		const std::string &	group_id,
		uint32_t *	stream_id
	)

overridevirtual

Parameters

media_info	specifies the stream.
playlist_name	is the name of the playlist that this stream should go.
stream_name	is the name of this stream.
group_id	is the group ID for this stream.
stream_id	is set to a value so that it can be used to call the other methods. If this returns false, the stream_id may be set to an invalid value.

Returns: true on sucess, false otherwise.
