reusableBundle()

template<class FT >

static FT * GstHwFrameTexturesBase::reusableBundle ( QVideoFrameTexturesUPtr &  old, HwVideoBufferPath  p  )

inlinestatic

Reuse probe: old downcasts to FT iff it is one of our bundles and came from path p. Qt 6.10's texture pool can pass CPU-fallback or Qt-owned texture bundles here, so the base cast must be checked before consulting sourcePath(). Caller still runs FT::matches() — the equality predicate differs per path.

setSourceSample()

void GstHwFrameTexturesBase::setSourceSample ( GstSample *  s )

inlinenoexcept

Transfers a ref into the bundle. Caller must have a fresh ref.
