Member Function Documentation

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

pure virtual

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.

Implemented in shaka::DashIopMpdNotifier, and shaka::SimpleMpdNotifier.

DashProfile shaka::MpdNotifier::dash_profile ( ) const

inline

Returns

The dash profile for this object.

Definition at line 108 of file mpd_notifier.h.

virtual bool shaka::MpdNotifier::Flush ( )

pure virtual

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.

Implemented in shaka::DashIopMpdNotifier, and shaka::SimpleMpdNotifier.

virtual bool shaka::MpdNotifier::Init ( )

pure virtual

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.

Implemented in shaka::DashIopMpdNotifier, and shaka::SimpleMpdNotifier.

virtual bool shaka::MpdNotifier::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  )

pure virtual

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.

Implemented in shaka::DashIopMpdNotifier, and shaka::SimpleMpdNotifier.

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

pure virtual

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.

Implemented in shaka::DashIopMpdNotifier, and shaka::SimpleMpdNotifier.

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

pure virtual

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.

Implemented in shaka::DashIopMpdNotifier, and shaka::SimpleMpdNotifier.

virtual bool shaka::MpdNotifier::NotifySampleDuration ( uint32_t  container_id, uint32_t  sample_duration  )

pure virtual

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.

Implemented in shaka::DashIopMpdNotifier, and shaka::SimpleMpdNotifier.
