  1. For our building we have a commission which maintains the building.
    We also have a security camera system, which was installed about 6 years ago.

    But I have a problem opening the video files from the system.

    I can copy them as .MP4 files but no common Mac program seems to be able to play it (I tried VLC, Mplayer and Quicktime).

    For Windows there is a playback application called: VSPlayer.exe
    But I don't have any Windows available, and installing Bootcamp just for that seems a bit extreme.

    Anyone any idea how I can find out which codec it is using and which piece of software would be able to play it?

    Let me know if you want a copy of a file to check it out, drop me a DM and I will e-mail a file to you.

    Not that extreme.

    But you could use MediaInfo/MediaInspector on the file and post the text output here...

    I can't, as Quicktime/VLC or what ever doesn't even recognize it as a video file.
    The manufacturer which produces the DVR for the security system seems to be: http://www.hikvision.com/

    Then take the file to a PC and use MediaInfo there.

    I note that on that site there is a Downloadable Directshow(?) Filter for Decoding/displaying in WMP and other players. That could come in handy (on a PC at least).

  5. MediaInfo doesn't seem to do much more with it either... https://www.box.com/shared/cc98f9e951134357b45c

    The security DVR should have an export mode.

    I don't think you have MI set up right (or some other app usurped it's shellextender). Or you have a corrupted file...

    Scott

    later edit: encrypted could be considered a form of corruption.

    eddv is right. you can't just copy the files off the hard drive. 99% use encrypted video. the surv. program has to export a separate video to be able to view elsewhere. it prevents someone without the proper password from viewing the videos.

  9. It's actually fairly easy, you don't even have to transcode it (as such) but you do need to rewrite the header from MPEG-PS to MPEG-4. Then PP will import.

    You need to install https://www.ffmpeg.org/ and do the following

    ffmpeg -filename.mp4 -flags +global_header -vcodec copy -acodec copy filename_converted.mp4

    it's very quick as it copies rather than encoding.

    You can even delete the original after as it is basically exactly the same video payload with a rewritten header.

    This works for Hickvivion IP cameras, if DVR cameras have the same problem this should work.

    Enjoy.
