You have a problem here. The input you are analyzing is not the stream that was created by the traffic camera but a file created with FFmpeg. So while there may absolutely be an issue (that we may or may not be able to fix), this file cannot be used to prove anything in court, I strongly suggest you do not try. The camera either produced a network stream or a raw H.264 stream. You hopefully still have access to it and FFmpeg may help you analyzing it. (Although H.264 timestamps are a known issue with FFmpeg and who knows if the camera manufacturer did any better with them than we did.)
