Yuyv is one of the storage formats of yuv422 sampling. The adjacent Y shares two adjacent CB and Cr. For the analysis of pixels '00 and y' 01, the CB and Cr values are cb00 and cr00, And the YUV values of other
mapping file class _ossmmapfile is actually managing a memory map of a file, because some database files can be very large, if you want to map the database file directly to a contiguous virtual address space, it is possible to map the failure, so _ Ossmmapfile is the mapping of files to multiple memory segments, and each memory segment corresponds to a _ossmmapsegment type object. All data segments mapped to memory are placed in a collection (Std::ve
