◆ makeHwVideoBuffer()
| std::unique_ptr< QHwVideoBuffer > makeHwVideoBuffer | ( | GstSample * | sample, |

| QVideoFrameFormat | format, | ||
| const HwVideoBufferContext & | context, | ||

| ) |
Selects the zero-copy QHwVideoBuffer for a GstSample; returns nullptr when no GPU path matches (CPU memcpy fallback).
