Detailed Description

Common base for GStreamer-backed QHwVideoBuffer subclasses.

Owns a ref on GstSample for its lifetime; holds a GstVideoInfo and QVideoFrameFormat so subclasses don't duplicate those three members.

validatePlaneHandles()

virtual bool GstHwVideoBuffer::validatePlaneHandles ( ) const

inlinevirtual

Streaming-thread sanity check on per-plane handles. Failure routes to CPU memcpy. GPU texture validity is checked later in mapTextures.
