streaming webcam from Ubuntu w/o X
Posted: 18 Apr 2011 08:47
I am trying to stream a webcam over a local network through a computer that is currently acting as a webserver which therefore has no X GUI. Through a lot of experimentation and trial-and-error, I have gotten the following command to work on my laptop:
I can then point Totem to the IP address and I have streaming video. So then I installedl vlc on the computer I want to set this up on and issue the same command (substituting v4l in place of v4l2) and I get this output:
By removing the '-noaudio' option, I can get the message down to:
I tried installing 'v4l-conf' and it's associated dependencies, but that didn't make a difference. Does it matter that the computer I want to run this command on does not have a GUI installed? It is simply a command-line server system. Is there anyway to get this to work on that computer? Or is there another way to do it? Thanks...
