Functions
static FFHWFramesContext *	ffhwframesctx (AVHWFramesContext *ctx)
int	ff_hwframe_map_create (AVBufferRef *hwframe_ref, AVFrame *dst, const AVFrame *src, void(*unmap)(AVHWFramesContext *ctx, HWMapDescriptor *hwmap), void *priv)
int	ff_hwframe_map_replace (AVFrame *dst, const AVFrame *src)
	Replace the current hwmap of dst with the one from src, used for indirect mappings like VAAPI->(DRM)->OpenCL/Vulkan where a direct interop is missing.
