... Fossapup has Guvcview. In general, VLC and mpv(and everything based on it) should be able to do this.
Thanks. Never knew Guvcview was built-in. It probably should be in the Menu under Multimedia, making it easy to find and use, since a growing number of us have and are using these local units for various needs.

... You can try using xawtv(viewer for TV tuners and cams) - PPM has it. ...
I tried xawtv on not one but 2 USBs to see if I could get either to show the camera's view. 'xawtv', after reading seems to have promise beyond just the webcams.
PPM installs fine. Yet in use???
Here's what is happening in the terminal...but NO video window emerges. 'video0 &video1' are from camera #1 while 'video2&3' got added when the 2nd camera was plugged in. Neither offered a window feed.

In my opinion, the most interesting combination of camera and computer is Stop Motion Animations. Many Soviet-Russian cartoons were made in this manner. Of course, "Wallace and Gromit" comes to mind from British animations.
A children's club(more likely a studio) was recently opened in my town, and there children sculpt various figures(people, animals, furniture and so on) from plasticine, and then create stop motion animations. Programs are used: Linux Stopmotion and qStopMotion, as well as Entangle and something else.
I'm trying to persuade a studio manager I know to switch to Puppy Linux
