Member Function Documentation

CopyFrom() [1/2]

std::shared_ptr< MediaSample > shaka::media::MediaSample::CopyFrom ( const uint8_t *  data, size_t  size, bool  is_key_frame  )

static

Create a MediaSample object from input.

Parameters

data	points to the buffer containing the sample data. Must not be NULL.
size	indicates sample size in bytes. Must not be negative.
is_key_frame	indicates whether the sample is a key frame.

Definition at line 43 of file media_sample.cc.

CopyFrom() [2/2]

std::shared_ptr< MediaSample > shaka::media::MediaSample::CopyFrom ( const uint8_t *  data, size_t  size, const uint8_t *  side_data, size_t  side_data_size, bool  is_key_frame  )

static

Create a MediaSample object from input.

Parameters

data	points to the buffer containing the sample data. Must not be NULL.
side_data	points to the buffer containing the additional data. Some containers allow additional data to be specified. Must not be NULL.
size	indicates sample size in bytes. Must not be negative.
side_data_size	indicates additional sample data size in bytes.
is_key_frame	indicates whether the sample is a key frame.

Definition at line 53 of file media_sample.cc.

CreateEOSBuffer()

std::shared_ptr< MediaSample > shaka::media::MediaSample::CreateEOSBuffer ( )

static

Create a MediaSample indicating we've reached end of stream. Calling any method other than end_of_stream() on the resulting buffer is disallowed.

Definition at line 77 of file media_sample.cc.

FromMetadata()

std::shared_ptr< MediaSample > shaka::media::MediaSample::FromMetadata ( const uint8_t *  metadata, size_t  metadata_size  )

static

Create a MediaSample object from metadata. Unlike other factory methods, this cannot be a key frame. It must be only for metadata.

Parameters

metadata	points to the buffer containing metadata. Must not be NULL.
metadata_size	is the size of metadata in bytes.

Definition at line 65 of file media_sample.cc.

SetData()

void shaka::media::MediaSample::SetData	(	const uint8_t *	data,
		size_t	data_size
	)

Set the data in this media sample. Note that this method involves data copying.

Parameters

data	points to the data to be copied.
data_size	is the size of the data to be copied.

Definition at line 110 of file media_sample.cc.

ToString()

std::string shaka::media::MediaSample::ToString

(

)

const

Returns

a human-readable string describing |*this|.

Definition at line 117 of file media_sample.cc.

TransferData()

void shaka::media::MediaSample::TransferData	(	std::shared_ptr< uint8_t >	data,
		size_t	data_size
	)

Transfer data to this media sample. No data copying is involved.

Parameters

data	points to the data to be transferred.
data_size	is the size of the data to be transferred.
