Detailed Description

This class is an MpdNotifier which will try its best to generate a DASH IF IOPv3 compliant MPD. e.g. All <ContentProtection> elements must be right under <AdaptationSet> and cannot be under <Representation>. All video Adaptation Sets have Role set to "main".

bool shaka::DashIopMpdNotifier::AddContentProtectionElement	(	uint32_t	container_id,
		const ContentProtectionElement &	content_protection_element
	)

overridevirtual

Adds content protection information to the MPD.

Parameters

container_id	is the nummeric container ID obtained from calling NotifyNewContainer().
content_protection_element	New ContentProtection element specification.

Returns: true on success, false otherwise.

Implements shaka::MpdNotifier.

Definition at line 136 of file dash_iop_mpd_notifier.cc.

bool shaka::DashIopMpdNotifier::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 146 of file dash_iop_mpd_notifier.cc.

bool shaka::DashIopMpdNotifier::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 51 of file dash_iop_mpd_notifier.cc.

bool shaka::DashIopMpdNotifier::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.

bool shaka::DashIopMpdNotifier::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 55 of file dash_iop_mpd_notifier.cc.

bool shaka::DashIopMpdNotifier::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 103 of file dash_iop_mpd_notifier.cc.

bool shaka::DashIopMpdNotifier::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.
