/* This structure is used to pass buffer offset from Camera-Hal to Encoder component
 * for specific algorithms like VSTAB & VNF
 *
 * With mediaserver hardening, Camera-Hal and Encoder are in separate processes.
 * These must use VideoNativeHandleMetadata. Ideally, we'd just do something like:
 *     #include <HardwareAPI.h>
 *     typedef struct VideoNativeHandleMetadata video_metadata_t;"
 * But HardwareAPI.h can't be included from C code like domx.
 *
 * So: REMEMBER TO ENSURE video_metadata_t MATCHES VideoNativeHandleMetadata!
