There are some potentially interesting reads searching for those terms: - https://spitzner.org/kkmoon.html - "Cheap Chinese camera garbled .264 files" - a VLC ticket: https://trac.videolan.org/vlc/ticket/22935 - the above leads to https://gitlab.com/mbunkus/mkvtoolnix/-/issues/2146 The first and third links include workarounds to strip unwanted bumph from the headers there, but I don't know if this also applies to your files. Uneducated guesses are often unhelpful, but at a quick glance it seems to me that the common element here is IP cameras. In my admittedly limited experience they can have some odd behaviour, like being tied to Internet Explorer / ActiveX (!!); I've heard at other times they want you to use their own app. I'm not sure if this is a deliberate attempt at lock-in or a result of odd tooling during development. In any case, expecting standards-compliant behaviour from those devices will lead to disappointment. No doubt someone with more experience can fill in the blanks in my amateur guesses.
