guvc video capture commandline

  • 772

I know how to use the -h option, I just don't see any commands to start video capture with file incrementation unless I press the video capture button.

What is the command line to start video capture guvcview using filename incrementation.

The option -n, --video=FILENAME Video File name (capture from start) will start video capture, however, the filename is overwritten unless the gui capture button is used.

command-line

  1. In order to run guvcview capture from command line you need to send a SIGUSR1 signal to the running application. First start it:

    guvcview --no_display -n capture_file.avi

    Then from a second shell window type the following:

    killall -s USR1 guvcview

    This will start a video capture and save the file in the current directory. You need to combine these 2 lines into a shell script if you want to run it automatically. Information from guvcview output:

    GUVCVIEW Signals:
SIGUSR1: Video stop/start capture
SIGUSR2: Image capture
SIGINT (ctrl+c): Exit
