Webcam image capture on Linux

I want to capture an image through a webcam in Linux. So I searched the Internet and found out that this can be done using mplayer or vlc.

The following is a command to capture an image using mplayer and the corresponding error.

[ root@localhost ~]# mplayer -vo png -frames 1 tv:// MPlayer SVN-r31628-4.4.4 (C) 2000-2010 MPlayer Team mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support. You will not be able to use your remote control. Playing tv://. TV file format detected. Selected driver: v4l2 name: Video 4 Linux 2 input author: Martin Olschewski < olschewski@zpr.uni-koeln.de > comment: first try, more to come ;-) v4l2: unable to open '/dev/video0': No such file or directory v4l2: ioctl set mute failed: Bad file descriptor v4l2: 0 frames successfully processed, 0 frames dropped. Exiting... (End of file) [ root@localhost ~]#

Please help me in resolving this error. I searched the net and found out about v4l2, but still can not solve the problem.

Your mistake is pretty clear. The webcam does not seem to register on / dev / video 0. In some cases, I found that encoders or other video devices register on / dev / videoX, where X can be any integer. Try changing your operator to try out different video devices.

You can also try using fswebcam, which has the useful ability to skip the first few frames - some webcams show damaged (or green) images for the first frame or two:

 fswebcam --skip 2

It can be configured to capture images every second:

fswebcam --skip 2 --loop 1
