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:
-
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.

| std::auto_ptr< MediaParser > gnash::media::gst::MediaHandlerGst::createMediaParser | ( | std::auto_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.

| 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:
-
srcFormat The source image color space dstFormat The 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] |
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.
| 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.
