Detailed Description

Demuxer is responsible for extracting elementary stream samples from a media file, e.g. an ISO BMFF file.

Definition at line 33 of file demuxer.h.

Constructor & Destructor Documentation

◆ Demuxer()

shaka::media::Demuxer::Demuxer ( const std::string & file_name )

explicit

Parameters

file_name specifies the input source. It uses prefix matching to create a proper File object. The user can extend File to support a custom File object with its own prefix.

Definition at line 81 of file demuxer.cc.

◆ ~Demuxer()

shaka::media::Demuxer::~Demuxer ( )

Definition at line 84 of file demuxer.cc.

Member Function Documentation

◆ Cancel()

void shaka::media::Demuxer::Cancel ( )

overridevirtual

Cancel a demuxing job in progress. Will cause Run to exit with an error status of type CANCELLED.

Implements shaka::media::OriginHandler.

Definition at line 134 of file demuxer.cc.

◆ container_name()

MediaContainerName shaka::media::Demuxer::container_name ( )

inline

Returns: Container name (type). Value is CONTAINER_UNKNOWN if the demuxer is not initialized.

Definition at line 57 of file demuxer.h.

◆ InitializeInternal()

Status shaka::media::Demuxer::InitializeInternal ( )

inlineoverrideprotectedvirtual

Internal implementation of initialize. Note that it should only initialize the MediaHandler itself. Downstream handlers are handled in Initialize().

Implements shaka::media::MediaHandler.

Definition at line 85 of file demuxer.h.

◆ Process()

Status shaka::media::Demuxer::Process ( std::unique_ptr< StreamData > stream_data )

inlineoverrideprotectedvirtual

Process the incoming stream data. Note that (1) stream_data.stream_index should be the input stream index; (2) The implementation needs to call DispatchXxx to dispatch the processed stream data to the downstream handlers after finishing processing if needed.

Implements shaka::media::MediaHandler.

Definition at line 86 of file demuxer.h.

◆ Run()

Status shaka::media::Demuxer::Run ( )

overridevirtual

Drive the remuxing from demuxer side (push). Read the file and push the Data to Muxer until Eof.

Implements shaka::media::OriginHandler.

Definition at line 93 of file demuxer.cc.

◆ set_dump_stream_info()

void shaka::media::Demuxer::set_dump_stream_info ( bool dump_stream_info )

inline

Definition at line 74 of file demuxer.h.

◆ set_input_format()

void shaka::media::Demuxer::set_input_format ( std::string input_format )

inline

Definition at line 78 of file demuxer.h.

◆ SetHandler()

Status shaka::media::Demuxer::SetHandler	(	const std::string &	stream_label,
		std::shared_ptr< MediaHandler >	handler
	)

Set the handler for the specified stream.

Parameters

stream_label	can be 'audio', 'video', or stream number (zero based).
handler	is the handler for the specified stream.

Definition at line 138 of file demuxer.cc.

◆ SetKeySource()

void shaka::media::Demuxer::SetKeySource ( std::unique_ptr< KeySource > key_source )

Set the KeySource for media decryption.

Parameters

key_source points to the source of decryption keys. The key source must support fetching of keys for the type of media being demuxed.

Definition at line 89 of file demuxer.cc.

◆ SetLanguageOverride()

void shaka::media::Demuxer::SetLanguageOverride	(	const std::string &	stream_label,
		const std::string &	language_override
	)

Override the language in the specified stream. If the specified stream is a video stream or invalid, this function is a no-op.

Parameters

stream_label	can be 'audio', 'video', or stream number (zero based).
language_override	is the new language.

Definition at line 148 of file demuxer.cc.

◆ ValidateOutputStreamIndex()

bool shaka::media::Demuxer::ValidateOutputStreamIndex ( size_t stream_index ) const

inlineoverrideprotectedvirtual

Validate if the stream at the specified index actually exists.

Reimplemented from shaka::media::MediaHandler.

Definition at line 90 of file demuxer.h.
