It might be that your update changed VLC's choice of video output, or broke the one VLC was using. Luckily, there are few you can try: Go to Tools->Preferences (If the menus are hidden behind a video gone wild, stop playback, or start vlc from menu or terminal without specifying a file to be played back) In the bottom left of the Preferences windows, ...

I have found Zoneminder to be a power hog so I don't use it. I have not had any luck using VLC. Foscam requires a plugin which sometimes works with Wine+Firefox+myfoscam.com. I have never been able to use myfoscam.com in Ubuntu+Firefox. I have had success using Ubuntu+Chrome+MyIpCam-apt from the Chrome store. My Netgear server forwards port 88 to the ...

I recommend opening the video in a media player to find the time where you want to split it. Then you can use ffmpeg with the following script. It does not re-encode the video.
