I use a Triplex Microdia USB webcam, which works pretty well AFAIK with the sn9c0102 driver and v4l in my kernel. All is basically fine with the camera and kernel driver.
Initially, I was quite pleased to simply get the image on the screen, and a decent image too for the most part; it's a cheap but good camera.
I have been using two applications; VideoView and sn_webcam. I am pretty sure that ONE of them used to save snapshots, but either I'm mistaken, or one of them broke. Anyhow, currently VideoView closes completely when I hit the snapshot button, and sn_webcam works great, except when I click the snapshot button it claims to be saving a picture (with a filename and everything) but it's actually lying to me-- There's no picture anywhere on my entire filesystem.
So , once again I Googled for Webcam apps for Linux, and wound up at the same place I always end up at (and I can't recall the name of the page, but no matter) and I finally decided to try 'wxcam', available as an Ubuntu package, a .DEB, or source. SO I got the source, read the READMEs, and learned that it needed close to 30 MB of crap behind it to function. I went ahead and downloaded all this 'crap', installed it all, made slack-packages for all the parts, and then went and downloaded 'wxcam', which despite the 30 MB of stuff behind it, was a measly 68 Kb.
Well, 'wxcam' totally blows. There's no picture, just static, and the GUI is totally borked. The menu items appear for one second, then go away, so to select a menu item, ya have to be REALLY FAST and good with a mouse, but the GUI and menus are still barely usable, they're mostly missing from the window. When it starts, it claims to be looking for a 'file' but doesn't indicate where or by what name. The only button that works is the 'Save Video' button, but it's no good if its saving a video of static, and I don't want AVI's anyhow, just stills. Also, the EXIT button causes a SegFault.
All in all, crummy.
Bringing me to my request: (after the rambling -- thatnks for reading): Do you use a webcam program for Linux, that comes in a source archive, that snaps decent photos, maybe even offers several sizes of image-view window, plus offers a few filters like brightness/contrast, coloration, gamma, and that sort of stuff? And it ACTUALLY WORKS?
If so, please point me towards it
Thank you all!
