◆ SimpleHlsNotifier()

shaka::hls::SimpleHlsNotifier::SimpleHlsNotifier ( const HlsParams & hls_params )

explicit

Parameters

hls_params contains parameters for setting up the notifier.

Definition at line 274 of file simple_hls_notifier.cc.

Member Function Documentation

◆ Flush()

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 510 of file simple_hls_notifier.cc.

◆ Init()

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

overridevirtual

Intialize the notifier.

Returns: true on sucess, false otherwise.

Implements shaka::hls::HlsNotifier.

Definition at line 293 of file simple_hls_notifier.cc.

◆ NotifyCueEvent()

bool shaka::hls::SimpleHlsNotifier::NotifyCueEvent	(	uint32_t	stream_id,
		int64_t	timestamp
	)

overridevirtual

Parameters

stream_id	is the value set by NotifyNewStream().
timestamp	is the timestamp of the CueEvent.

Returns: true on success, false otherwise.

Implements shaka::hls::HlsNotifier.

Definition at line 420 of file simple_hls_notifier.cc.

◆ NotifyEncryptionUpdate()

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.

Implements shaka::hls::HlsNotifier.

Definition at line 432 of file simple_hls_notifier.cc.

◆ NotifyKeyFrame()

bool shaka::hls::SimpleHlsNotifier::NotifyKeyFrame	(	uint32_t	stream_id,
		int64_t	timestamp,
		uint64_t	start_byte_offset,
		uint64_t	size
	)

overridevirtual

Called on every key frame. For Video only.

Parameters

stream_id	is the value set by NotifyNewStream().
timestamp	is the timesamp of the key frame in timescale units passed in media_info.
start_byte_offset	is the offset of where the keyframe starts.
size	is the size in bytes.

Implements shaka::hls::HlsNotifier.

Definition at line 405 of file simple_hls_notifier.cc.

◆ NotifyNewSegment()

bool shaka::hls::SimpleHlsNotifier::NotifyNewSegment	(	uint32_t	stream_id,
		const std::string &	segment_name,
		int64_t	start_time,
		int64_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.

Definition at line 354 of file simple_hls_notifier.cc.

◆ NotifyNewStream()

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.

Implements shaka::hls::HlsNotifier.

Definition at line 297 of file simple_hls_notifier.cc.

◆ NotifySampleDuration()

bool shaka::hls::SimpleHlsNotifier::NotifySampleDuration	(	uint32_t	stream_id,
		int32_t	sample_duration
	)

overridevirtual

Change the sample duration of stream with stream_id.

Parameters

stream_id	is the value set by NotifyNewStream().
sample_duration	is the duration of a sample in timescale of the media.

Returns: true on success, false otherwise. This may fail if the stream specified by stream_id does not exist.
