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 149 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 45 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_idContainer ID obtained from calling NotifyNewContainer().
timestampis the timestamp of the CueEvent.
Returns
true on success, false otherwise.

Implements shaka::MpdNotifier.

Definition at line 97 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_idContainer ID obtained from calling NotifyNewContainer().
drm_uuidis the UUID of the DRM for encryption.
new_key_idis the new key ID for the key.
new_psshis 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 125 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_infois the MediaInfo that will be passed to MpdBuilder.
[out]container_idis 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 49 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_idContainer ID obtained from calling NotifyNewContainer().
start_timeis the start time of the new segment, in units of the stream's time scale.
durationis the duration of the new segment, in units of the stream's time scale.
sizeis the new segment size in bytes.
Returns
true on success, false otherwise.

Implements shaka::MpdNotifier.

Definition at line 83 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_idContainer ID obtained from calling NotifyNewContainer().
sample_durationis 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.
