Detailed Description

A simple MpdNotifier implementation which receives muxer listener event and generates an Mpd file.

Definition at line 29 of file simple_mpd_notifier.h.

Member Function Documentation

◆ Flush()

bool shaka::SimpleMpdNotifier::Flush ( )

overridevirtual

Call this method to force a flush. Implementations might not write out the MPD to a stream (file, stdout, etc.) when the MPD is updated, this forces a flush.

Implements shaka::MpdNotifier.

Definition at line 184 of file simple_mpd_notifier.cc.

◆ Init()

bool shaka::SimpleMpdNotifier::Init ( )

overridevirtual

Initializes the notifier. For example, if this notifier uses a network for notification, then this would set up the connection with the remote host.

Returns: true on success, false otherwise.

Implements shaka::MpdNotifier.

Definition at line 32 of file simple_mpd_notifier.cc.

◆ NotifyCueEvent()

bool shaka::SimpleMpdNotifier::NotifyCueEvent	(	uint32_t	container_id,
		uint64_t	timestamp
	)

overridevirtual

Notifies MpdBuilder that there is a new CueEvent.

Parameters

container_id	Container ID obtained from calling NotifyNewContainer().
timestamp	is the timestamp of the CueEvent.

Returns: true on success, false otherwise.

Implements shaka::MpdNotifier.

Definition at line 100 of file simple_mpd_notifier.cc.

◆ NotifyEncryptionUpdate()

bool shaka::SimpleMpdNotifier::NotifyEncryptionUpdate	(	uint32_t	container_id,
		const std::string &	drm_uuid,
		const std::vector< uint8_t > &	new_key_id,
		const std::vector< uint8_t > &	new_pssh
	)

overridevirtual

Notifiers MpdBuilder that there is a new PSSH for the container. This may be called whenever the key has to change, e.g. key rotation.

Parameters

container_id	Container ID obtained from calling NotifyNewContainer().
drm_uuid	is the UUID of the DRM for encryption.
new_key_id	is the new key ID for the key.
new_pssh	is the new pssh box (including the header).

Attention: This might change or get removed once DASH IF IOP specification writes a clear guideline on how to handle key rotation.

Implements shaka::MpdNotifier.

Definition at line 144 of file simple_mpd_notifier.cc.

◆ NotifyMediaInfoUpdate()

bool shaka::SimpleMpdNotifier::NotifyMediaInfoUpdate	(	uint32_t	container_id,
		const MediaInfo &	media_info
	)

overridevirtual

Parameters

container_id	Container ID obtained from calling NotifyNewContainer().
media_info	is the new MediaInfo. Note that codec related information cannot be updated.

Implements shaka::MpdNotifier.

Definition at line 168 of file simple_mpd_notifier.cc.

◆ NotifyNewContainer()

bool shaka::SimpleMpdNotifier::NotifyNewContainer	(	const MediaInfo &	media_info,
		uint32_t *	container_id
	)

overridevirtual

Notifies the MpdBuilder that there is a new container along with media_info. Live may have multiple files (segments) but those should be notified via NotifyNewSegment().

Parameters

	media_info	is the MediaInfo that will be passed to MpdBuilder.
[out]	container_id	is the numeric ID of the container, possibly for NotifyNewSegment() and AddContentProtectionElement(). Only populated on success.

Returns: true on success, false otherwise.

Implements shaka::MpdNotifier.

Definition at line 36 of file simple_mpd_notifier.cc.

◆ NotifyNewSegment()

bool shaka::SimpleMpdNotifier::NotifyNewSegment	(	uint32_t	container_id,
		uint64_t	start_time,
		uint64_t	duration,
		uint64_t	size
	)

overridevirtual

Notifies MpdBuilder that there is a new segment ready. For live, this is usually a new segment, for VOD this is usually a subsegment.

Parameters

container_id	Container ID obtained from calling NotifyNewContainer().
start_time	is the start time of the new segment, in units of the stream's time scale.
duration	is the duration of the new segment, in units of the stream's time scale.
size	is the new segment size in bytes.

Returns: true on success, false otherwise.

Implements shaka::MpdNotifier.

Definition at line 86 of file simple_mpd_notifier.cc.

◆ NotifySampleDuration()

bool shaka::SimpleMpdNotifier::NotifySampleDuration	(	uint32_t	container_id,
		uint32_t	sample_duration
	)

overridevirtual

Change the sample duration of container with container_id.

Parameters

container_id	Container ID obtained from calling NotifyNewContainer().
sample_duration	is the duration of a sample in timescale of the media.

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