MISB ST 0604 and ST 2101 require user data unregistered SEI messages (precision timestamps and sensor identifiers) to be included. That currently isn't supported for libx264. This patch adds support for user data unregistered SEI messages in accordance with ISO/IEC 14496-10:2020(E) section D.1.7 (syntax) and D.2.7 (semantics). This code is based on a similar change for libx265 (commit 1f58503013720700a5adfd72c708e6275aefc165). Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
