QVideoFrameTextures Class Referenceabstract

QVideoFrameTextures is the base class representing an abstraction layer between QVideoFrame's texture(s) and rhi's plane textures. QVideoFrameTextures must own the inner rhi textures or share ownership. QVideoFrameTextures instances are propagated to QVideoFrameTexturesPool, where their lifetime is managed according to results of QRhi::currentFrameSlot upon rendering. More...

QVideoFrameTextures is the base class representing an abstraction layer between QVideoFrame's texture(s) and rhi's plane textures. QVideoFrameTextures must own the inner rhi textures or share ownership.

Member Function Documentation

◆ onFrameEndInvoked()

virtual void QVideoFrameTextures::onFrameEndInvoked ( )
inlinevirtual

The virtual method should be invoked after QRhi::endFrame to unmap and free internal resources that are not needed anymore.

Reimplemented in QVideoTextureHelper::QVideoFrameTexturesFromMemory.

Definition at line 65 of file qhwvideobuffer_p.h.

◆ setSourceFrame()

void QVideoFrameTextures::setSourceFrame ( QVideoFrame sourceFrame)
inline

Sets the source frame. It is a temporary solution to delegate frame's shared ownership to the instance. Ideally, the creators of QVideoFrameTextures's or QVideoFrameTexturesHandles's instances should manage ownership.

Definition at line 75 of file qhwvideobuffer_p.h.

◆ takeHandles()

virtual QVideoFrameTexturesHandlesUPtr QVideoFrameTextures::takeHandles ( )
inlinevirtual

Reimplemented in QVideoTextureHelper::QVideoFrameTexturesFromHandlesSet.

Definition at line 67 of file qhwvideobuffer_p.h.

◆ texture()

virtual QRhiTexture * QVideoFrameTextures::texture ( uint plane) const
pure virtual

Implemented in QAndroidVideoFrameTextures, QAndroidVideoFrameTextures, QVideoFrameD3D11Textures, QVideoFrameD3D11Textures, and QVideoTextureHelper::QVideoFrameTexturesFromRhiTextureArray.
