Type Definition x264_dev::sys::X264SeiPayloadT

type X264SeiPayloadT = x264_sei_payload_t;

Arbitrary user SEI:

Payload size is in bytes and the payload pointer must be valid.

Payload types and syntax can be found in Annex D of the H.264 Specification. SEI payload alignment bits as described in Annex D must be included at the end of the payload if needed. The payload should not be NAL-encapsulated. Payloads are written first in order of input, apart from in the case when HRD is enabled where payloads are written after the Buffering Period SEI.
