"I'm working on a new Ubuntu configuration to deploy for friends and family. One of the capabilities I wanted to add was simple remote webcam viewing. I saw an article about webcam_server. While it's old and only does images it met my requirements. The primary limitation is that it's a command-line application. It can be launched from a XDG desktop file and will default to /dev/video0 but on systems with more than one video device a terminal is needed. I did spend some time testing streaming with VLC but it doesn't show a device list for selection either and it's streaming configuration dialogs are confusing at best. To deploy webcam-server I had to make it more friendly which meant making a video device selection dialog for it. My current programming hammer is Bash shell scripting (Applesoft BASIC was the other option) but it's not enough for GUI design. To add that capability I turned to what I call "dialoger" utilities that can produce GUI dialogs and provide feedback to command-line applications.

"When I started this project the only dialoger I knew about was dialog which is text-based and I needed something that would run in X. From researching alternatives to dialog I found xmessage which led to gxmessage and eventually Zenity. Plenty to choose from and all different. Now I had another problem - which one to use with each desktop environment?"
