// - T35 has 3 possible data types: CLOSE_CAPTION, HDR10PLUS, AFD
// - MASTERING_DISPLAY_COLOUR
// - CONTENT_LIGHT_LEVEL
// - USER_DATA_UNREGISTERED
// - CUSTOM_SEI
// Note: USER_DATA_UNREGISTERED may have arbitrary size but SEI buffer
// size is limited. The SEI buffer on decoder has the following format:
//       [byte0: #entries][entry1]..[entryN]
// up to (1 + sizeof(ni_sei_header_t) + NI_MAX_SEI_DATA) bytes maximum;
// where [entryX] := [ni_sei_header][payload]
//       [payload] of ni_sei_header.size: present only if ni_sei_header.status == 1
//         X in [1..N] with N <= #entries
//         N == #entries only if NI_MAX_SEI_DATA is large enough to store all #entries
// ex:
//     entryX header fits in the buffer during SEI extration, but payload can't fit in;
//            so only entryX header is stored but payload is drop with status set 0.
//     entryX header can't fit in the buffer (SEI buffer full); so extryX is not stored
//            in the SEI buffer (neither will any further SEIs)
//
// To maintain alignment, current implementation retrieves SEI data buffer from
// entry 1's payload onwards (skipping byte0, and entry 1's header),
// while #entries (same value as SEI buffer byte0) and entry 1's header are notified
// separately via metadata.
