Member Function Documentation

abort()

void G3D::VideoOutput::abort

(

)

Aborts writing video file and ends encoding.

append() [1/3]

void G3D::VideoOutput::append	(	const shared_ptr< Texture > &	frame,
		bool	invertY = false
	)

append() [2/3]

void G3D::VideoOutput::append

(

const shared_ptr< PixelTransferBuffer > &

frame

)

append() [3/3]

void G3D::VideoOutput::append	(	class RenderDevice *	rd,
		bool	useBackBuffer = false
	)

Append the current frame on the RenderDevice to this video.

Parameters

useBackBuffer

If true, read from the back buffer (the current frame) instead of the front buffer. to be replaced/removed.

commit()

void G3D::VideoOutput::commit

(

)

Finishes writing video file and ends encoding.

create()

static shared_ptr<VideoOutput> G3D::VideoOutput::create ( const String &  filename, const Settings &  settings  )

static

Video files have a file format and a codec.

VideoOutput chooses the file format based on the filename's extension (e.g., .avi creates an AVI file) and the codec based on Settings::codec

createShared()

template<class T , class ... ArgTypes>

static shared_ptr<T> G3D::ReferenceCountedObject::createShared ( ArgTypes &&...  args )

inlinestaticprotectedinherited

Like std::make_shared, but works for protected constructors.

Call as createShared<myclass>.

encodeFrame()

void G3D::VideoOutput::encodeFrame ( const uint8 *  pixels, const ImageFormat *  format  )

protected

filename()

const String& G3D::VideoOutput::filename ( ) const

inline

finished()

bool G3D::VideoOutput::finished ( )

inline

initialize()

bool G3D::VideoOutput::initialize ( )

settings()

const Settings& G3D::VideoOutput::settings ( ) const

inline

shutdown()

void G3D::VideoOutput::shutdown ( )

protected

validSettings()

bool G3D::VideoOutput::validSettings ( )
