Detailed Description

Outputfile is the default implentation of wrapper which uses LibAV/FFMpeg.

Definition at line 17 of file OutputFile.hpp.

Constructor & Destructor Documentation

avtranscoder::OutputFile::OutputFile ( const OutputFile & outputFile )

private

avtranscoder::OutputFile::OutputFile	(	const std::string &	filename,
		const std::string &	formatName = `""`,
		const std::string &	mimeType = `""`
	)

Create an output media file.

Parameters

filename	resource to access
formatName	should matches with the names of the registered formats
mimeType	should matches with the MIME type of the registered formats

Note: The caller should indicate formatName and/or mimeType if the filename has no extension.; The ressource is allocated when beginWrap.

Member Function Documentation

IOutputStream & avtranscoder::OutputFile::addAudioStream ( const AudioCodec & audioCodec )

virtual

Add an audio output stream.

Parameters

audioCodec description of output stream

Reimplemented from avtranscoder::IOutputFile.

Definition at line 68 of file OutputFile.cpp.

References _formatContext, _outputStreams, avtranscoder::FormatContext::addAVStream(), avtranscoder::ICodec::getAVCodec(), avtranscoder::ICodec::getAVCodecContext(), and avtranscoder::FormatContext::getNbStreams().

IOutputStream & avtranscoder::OutputFile::addDataStream ( const DataCodec & dataCodec )

virtual

Add a data output stream.

Parameters

dataCodec description of output stream

Reimplemented from avtranscoder::IOutputFile.

Definition at line 88 of file OutputFile.cpp.

References _formatContext, _outputStreams, avtranscoder::FormatContext::addAVStream(), avtranscoder::ICodec::getAVCodec(), and avtranscoder::FormatContext::getNbStreams().

void avtranscoder::OutputFile::addMetadata ( const PropertyVector & data )

Add metadata to the output file.

Note: Depending on the format, you are not sure to find your metadata after the transcode.

Definition at line 239 of file OutputFile.cpp.

void avtranscoder::OutputFile::addMetadata	(	const std::string &	key,
		const std::string &	value
	)

Definition at line 247 of file OutputFile.cpp.

References _formatContext, and avtranscoder::FormatContext::addMetaData().

IOutputStream & avtranscoder::OutputFile::addVideoStream ( const VideoCodec & videoCodec )

virtual

Add a video output stream.

Parameters

videoCodec description of output stream

Reimplemented from avtranscoder::IOutputFile.

Definition at line 33 of file OutputFile.cpp.

References _formatContext, _outputStreams, avtranscoder::FormatContext::addAVStream(), FF_INPUT_BUFFER_PADDING_SIZE, avtranscoder::ICodec::getAVCodec(), avtranscoder::ICodec::getAVCodecContext(), and avtranscoder::FormatContext::getNbStreams().

bool avtranscoder::OutputFile::beginWrap ( )

virtual

Open ressource, write header, and setup specific wrapping options given when call setupWrapping.

Note: Need to add the streams to mux before calling this method.; After this call, a new list of AVOption, relative to the format choosen, will be available for the OutputFile.

Implements avtranscoder::IOutputFile.
