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...
