Member Function Documentation

◆ fbo()

QOpenGLFramebufferObject* QtAV::GLSLFilter::fbo ( ) const

◆ isSupported()

bool QtAV::GLSLFilter::isSupported ( VideoFilterContext::Type ct ) const

inlinevirtual

Reimplemented from QtAV::VideoFilter.

◆ opengl()

OpenGLVideo* QtAV::GLSLFilter::opengl ( ) const

opengl Currently you can only use it to set custom shader OpenGLVideo.setUserShader()

◆ outputSize()

QSize QtAV::GLSLFilter::outputSize ( ) const

outputSize Output frame size.

FBO uses the same size to render. An empty size means using the input frame size

Returns

◆ outputSizeChanged

void QtAV::GLSLFilter::outputSizeChanged ( const QSize & size )

signal

◆ process()

void QtAV::GLSLFilter::process	(	Statistics *	statistics,
		VideoFrame *	frame = `0`
	)

protectedvirtual

process Draw video frame into fbo and apply the user shader from opengl()->userShader();

Parameters

frame input frame can be a frame holding host memory data, or any other GPU frame can interop with OpenGL texture (including frames from HW decoders in QtAV). Output frame holds an RGB texture, which can be processed in the next GPU filter, or rendered by OpenGL renderers. When process() is done, FBO before before process() is bounded.

Implements QtAV::VideoFilter.

◆ setOutputSize() [1/2]

void QtAV::GLSLFilter::setOutputSize ( const QSize & value )

◆ setOutputSize() [2/2]

void QtAV::GLSLFilter::setOutputSize	(	int	width,
		int	height
	)
