Classes
struct	HwBuffers::HwBufferEnvConfig
struct	HwBuffers::PathStats
	Formatted per-path counters + delivered total; reset=true reads-and-clears (teardown), false peeks. More...

Namespaces
namespace	HwBuffers

Functions
void	HwBuffers::initializeOnce () noexcept
	One-time process init; single call site for future lazy bridge registration.
const HwBufferEnvConfig &	HwBuffers::hwBufferEnvConfig () noexcept
	Lazily parses + logs the toggle config on first call; thread-safe via static-init guarantees.
GstBusSyncReply	HwBuffers::onBusSyncMessage (GstBus *bus, GstMessage *msg, gpointer userData) noexcept
	Bus sync handler (GstBusSyncHandler) installed on every pipeline; no-op when no GPU path compiled.
void	HwBuffers::dispatchBusMessage (GstMessage *msg) noexcept
	Receiver-side bus hook; drops cached GPU devices on GST_MESSAGE_ERROR. No-op when no GPU paths compiled.
void	HwBuffers::onPipelineRestart () noexcept
	Pipeline-restart hook; re-arms one-shot priming latches so a restart can prime on the next NEED_CONTEXT.
void	HwBuffers::resetCachedGpuResources () noexcept
	Drop process-wide native GPU handles tied to the current Qt scene-graph device/context.
void	HwBuffers::connectMainWindow (QQuickWindow *window) noexcept
	Wire the main QQuickWindow into the RHI-capture path so snapshots follow its QRhi; no-op without GPU.
bool	HwBuffers::answerSinkBinContextQuery (GstQuery *query) noexcept
	Synchronously answer GST_QUERY_CONTEXT (gst.gl.GLDisplay/app_context); false -> let bus NEED_CONTEXT run.
PathStats	HwBuffers::formatPathStats (bool reset) noexcept
QString	HwBuffers::takeExtraPathStats () noexcept
	Path-specific extras after formatPathStats (GL reuse/sync waits); reads-and-clears, teardown only.
