Member Function Documentation

◆ associatedCurrentThreadRhi()

virtual QRhi * QHwVideoBuffer::associatedCurrentThreadRhi ( ) const
inlinevirtual

Reimplemented in QFFmpegVideoBuffer, and QWasmGLTextureVideoBuffer.

Definition at line 91 of file qhwvideobuffer_p.h.

◆ externalTextureMatrix()

virtual QMatrix4x4 QHwVideoBuffer::externalTextureMatrix ( ) const
inlinevirtual

Definition at line 99 of file qhwvideobuffer_p.h.

◆ format()

QVideoFrameFormat QHwVideoBuffer::format ( ) const
inlinefinalvirtual

Gets \l QVideoFrameFormat of the underlying video buffer.

The format must be available upon construction of \l QVideoFrame. QVideoFrame will contain won instance of the given format, that can be detached and modified.

Implements QAbstractVideoBuffer.

◆ initTextureConverter()

virtual void QHwVideoBuffer::initTextureConverter ( QRhi & )
inlinevirtual

Reimplemented in QFFmpegVideoBuffer.

Definition at line 108 of file qhwvideobuffer_p.h.

◆ isDmaBuf()

virtual bool QHwVideoBuffer::isDmaBuf ( ) const
inlinevirtual

Reimplemented in QtMultimediaPrivate::QDmaBufVideoBuffer.

Definition at line 110 of file qhwvideobuffer_p.h.

◆ mapTextures() [1/2]

virtual QVideoFrameTexturesUPtr QHwVideoBuffer::mapTextures ( QRhi & )
