Detailed Description

GST based MediaHandler.

The module implements the MediaHandler factory as required by Gnash core for a loadable media handler module.

It uses gstreamer: http://gstreamer.freedesktop.org/

Starting point is MediaHandlerGst.

Member Function Documentation

§ cameraNames()

void gnash::media::gst::MediaHandlerGst::cameraNames ( std::vector< std::string > & names ) const

virtual

Return a list of available cameras.

This is re-generated every time the function is called.

Implements gnash::media::MediaHandler.

References gnash::media::gst::VideoInputGst::getNames().

§ createAudioDecoder()

std::unique_ptr< AudioDecoder > gnash::media::gst::MediaHandlerGst::createAudioDecoder ( const AudioInfo & info )

virtual

Create an AudioDecoder for decoding what's specified in the AudioInfo.

Parameters

info	AudioInfo class with all the info needed to decode the sound correctly.

Returns: Will always return a valid AudioDecoder or throw a gnash::MediaException if a fatal error occurs.

Implements gnash::media::MediaHandler.

References _, gnash::media::AUDIO_CODEC_SPEEX, gnash::media::AudioInfo::codec, gnash::media::CODEC_TYPE_FLASH, gnash::media::MediaHandler::createFlashAudioDecoder(), and gnash::media::AudioInfo::type.

§ createMediaParser()

std::unique_ptr< MediaParser > gnash::media::gst::MediaHandlerGst::createMediaParser ( std::unique_ptr< IOChannel > stream )

virtual

Return an appropriate MediaParser for given input.

Parameters

stream Input stream, ownership transferred

Returns: 0 if no parser could be created for the input

NOTE: the default implementation returns an FLVParser for FLV input or 0 for others.

Reimplemented from gnash::media::MediaHandler.

References gnash::media::MediaHandler::isFLV(), and gnash::log_error().

§ createVideoConverter()

std::unique_ptr< VideoConverter > gnash::media::gst::MediaHandlerGst::createVideoConverter	(	ImgBuf::Type4CC	srcFormat,
		ImgBuf::Type4CC	dstFormat
	)

virtual

Create an VideoConverter for converting between color spaces.

Parameters

srcFormat	The source image color space
dstFormat	The destination image color space

Returns: A valid VideoConverter or a NULL unique_ptr if a fatal error occurs.

Implements gnash::media::MediaHandler.

References gnash::log_error().

§ createVideoDecoder()

std::unique_ptr< VideoDecoder > gnash::media::gst::MediaHandlerGst::createVideoDecoder ( const VideoInfo & info )

virtual

Create a VideoDecoder for decoding what's specified in the VideoInfo.

Parameters

info	VideoInfo class with all the info needed to decode the image stream correctly.

Returns: Will always return a valid VideoDecoder or throw a gnash::MediaException if a fatal error occurs.

Implements gnash::media::MediaHandler.

References _, gnash::media::gst::ExtraInfoGst::caps, gnash::media::VideoInfo::codec, gnash::media::CODEC_TYPE_FLASH, gnash::media::ExtraVideoInfoFlv::data, gnash::media::VideoInfo::extra, height, gnash::media::VideoInfo::height, gnash::log_error(), gnash::media::ExtraVideoInfoFlv::size, gnash::media::VideoInfo::type, width, and gnash::media::VideoInfo::width.

§ description()

std::string gnash::media::gst::MediaHandlerGst::description ( ) const

virtual

Return a description of this media handler.

Implements gnash::media::MediaHandler.

References gnash::key::s.

§ getAudioInput()

AudioInput * gnash::media::gst::MediaHandlerGst::getAudioInput ( size_t index )

virtual

Implements gnash::media::MediaHandler.

§ getVideoInput()

VideoInput * gnash::media::gst::MediaHandlerGst::getVideoInput ( size_t index )

virtual

Return a VideoInput.

This is always owned by the MediaHandler, but will remain alive as long as it is referenced by a Camera object.

Parameters

index The index of the VideoInput to return.

Returns: A Video Input corresponding to the specified index or null if it is not available.

Implements gnash::media::MediaHandler.
