BTW: I also read on the “help” information, that it is possible to pass “Time Stamps”,
--copy-timestamp <st> <fps> Enable copy timestamp with start timestamp(st) in seconds for decode fps(fps) (for input-nalu mode)
NOTE: copy-timestamp used to demonstrate how timestamp can be associated with an individual H264/H265 frame to achieve video-synchronization
But there is not documentation available in how to achieve this…
