Add a new side data entry to an array based on existing side data, taking a reference towards the contained AVBufferRef.

@param sd pointer to array of side data to which to add another entry, or to NULL in order to start a new array. @param nb_sd pointer to an integer containing the number of entries in the array. @param src side data to be cloned, with a new reference utilized for the buffer. @param flags Some combination of AV_FRAME_SIDE_DATA_FLAG_* flags, or 0.

@return negative error code on failure, >=0 on success. @note In case of AV_FRAME_SIDE_DATA_FLAG_UNIQUE being set, entries of matching AVFrameSideDataType will be removed before the addition is attempted. @note In case of AV_FRAME_SIDE_DATA_FLAG_REPLACE being set, if an entry of the same type already exists, it will be replaced instead.
