Member Enumeration Documentation

anonymous enum

Numbers chosen to estimate the duration of a buffer if none is set and there is not enough information to get a better estimate.

Enumerator
kDefaultAudioBufferDurationInMs	Common 1k samples @44.1kHz.
kDefaultVideoBufferDurationInMs	Chosen to represent 16fps duration, which will prevent MSE stalls in videos with frame-rates as low as 8fps.

Create a WebMClusterParser from given parameters.

Parameters

timecode_scale	indicates timecode scale for the clusters.
audio_stream_info	references audio stream information. It will be NULL if there are no audio tracks available.
video_stream_info	references video stream information. It will be NULL if there are no video tracks available.
vp_config	references vp configuration record. Only useful for video.
audio_default_duration	indicates default duration for audio samples.
video_default_duration	indicates default duration for video samples.
text_tracks	contains text track information.
ignored_tracks	contains a list of ignored track ids.
audio_encryption_key_id	indicates the encryption key id for audio samples if there is an audio stream and the audio stream is encrypted. It is empty otherwise.
video_encryption_key_id	indicates the encryption key id for video samples if there is a video stream and the video stream is encrypted. It is empty otherwise.
new_sample_cb	is the callback to emit new samples.
init_cb	is the callback to initialize streams.
decryption_key_source	points to a decryption key source to fetch decryption keys. Should not be NULL if the tracks are encrypted.

inline

Definition at line 154 of file webm_cluster_parser.h.

bool shaka::media::WebMClusterParser::Flush ( )

Flush data currently in the parser and reset the parser so it can accept a new cluster.

Definition at line 91 of file webm_cluster_parser.cc.

int shaka::media::WebMClusterParser::Parse	(	const uint8_t *	buf,
		int	size
	)

Parses a WebM cluster element in |buf|.

Returns: -1 if the parse fails.; 0 if more data is needed.; The number of bytes parsed on success.
