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

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().

std::auto_ptr< AudioDecoder > gnash::media::gst::MediaHandlerGst::createAudioDecoder ( const AudioInfo info) [virtual]

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

Parameters:
infoAudioInfo 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.

std::auto_ptr< MediaParser > gnash::media::gst::MediaHandlerGst::createMediaParser ( std::auto_ptr< IOChannel stream) [virtual]

Return an appropriate MediaParser for given input.

Parameters:
streamInput 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 assert.

std::auto_ptr< VideoConverter > gnash::media::gst::MediaHandlerGst::createVideoConverter ( ImgBuf::Type4CC  srcFormat,
ImgBuf::Type4CC  dstFormat 
) [virtual]

Create an VideoConverter for converting between color spaces.

Parameters:
srcFormatThe source image color space
dstFormatThe destination image color space
Returns:
A valid VideoConverter or a NULL auto_ptr if a fatal error occurs.

Implements gnash::media::MediaHandler.

std::auto_ptr< VideoDecoder > gnash::media::gst::MediaHandlerGst::createVideoDecoder ( const VideoInfo info) [virtual]
std::string gnash::media::gst::MediaHandlerGst::description ( ) const [virtual]

Return a description of this media handler.

Implements gnash::media::MediaHandler.

References gnash::key::s.

AudioInput * gnash::media::gst::MediaHandlerGst::getAudioInput ( size_t  index) [virtual]
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:
indexThe 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.
