Source 
pub unsafe extern "C" fn mbuf_coded_video_frame_get_metadata(
    frame: *mut mbuf_coded_video_frame,
    meta: *mut *mut vmeta_frame,
) -> c_int
Expand description

Get the video metadata associated with a frame.

The returned metadata has its reference count increased, so the caller needs to call vmeta_frame_unref() on the metadata when no longer needed. If the frame does not contain metadata, this call will return -ENOENT and set *meta to NULL.

@param frame: The frame. @param meta: [out] The metadata.

@return 0 on success, negative errno on error.
