Unofficial VirtualDub Support Forums > Newbie Questions > Capture Webcam With Unknown Duration Over Cmd Line

Posted by: shuriken Feb 6 2014, 12:23 PM

Hi! I'm new to VDub, but I thought that it could help me with a problem. I need to record (not stream) from a webcam and store it to a mp4-file (H.264) automated. The command line help showed me the capstart-flag and it says that the time is optional... but how to stop it? My problem is, that I cannot predict how long the video needs to be, so I want to start capturing with the first command and stop(and save) the video with the second command, but there is no "capstop" or similar. Hope this is not impossible

Currently, VirtualDub doesn't support this -- it would require communicating with an instance that's already running. All of the commands that are provided now only just tell a new instance what to do on startup, so they haven't required this plumbing.
