Constructor & Destructor Documentation

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.

Member Function Documentation

void shaka::media::Demuxer::Cancel

(

)

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

Definition at line 232 of file demuxer.cc.

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

inline

Returns

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

Definition at line 72 of file demuxer.h.

Status shaka::media::Demuxer::Initialize

(

)

Initialize the Demuxer. Calling other public methods of this class without this method returning OK, results in an undefined behavior. This method primes the demuxer by parsing portions of the media file to extract stream information.

Returns

OK on success.

Definition at line 56 of file demuxer.cc.

Status shaka::media::Demuxer::Run

(

)

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

Definition at line 173 of file demuxer.cc.

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 52 of file demuxer.cc.

const std::vector<MediaStream*>& shaka::media::Demuxer::streams ( )

inline

Returns

Streams in the media container being demuxed. The caller cannot add or remove streams from the returned vector, but the caller is allowed to change the internal state of the streams in the vector through MediaStream APIs.
