MG starts this page on June 12th 2005, to list some of the Tcl applications or extensions for working with Digital Cameras or Webcams.
I wanted a capture some footage from a webcam (or at least see if it was possible) for embedding it in a webpage (I have a program that converts most common movie formats into Flash movies files at the touch of a button), and thought I'd see about doing it in Tcl. There seem to be several extensions (generally aimed at MS Windows, it seems) for working with web cams, so below is a list of all the ones I've found, after a very brief search. If anyone has any more extensions, or info on using webcams or digital still cameras with Tcl and/or Tk, please post it here!
QuickTimeTcl provides a webcam capture facility, according to it's homepage, which I believe runs on MS Windows and MacOS (and requires that Quicktime be installed, on both).
Pat Thoyts wrote a Tk widget for displaying streaming video from a webcam. It can also take still images from the webcam, but can't save the video to a file/pipe it through a channel, at present. See [L1 ] and [L2 ] for more info.
The AviCapTcl package on Sourceforge (at [L3 ], and apparantly also [L4 ], though the second is down due to a work at present) also supports webcam video (and audio) capture to an AVI movie file.
And finally, though I haven't looked at it yet (and taken straight from the Applications in Tcl and Tcl/Tk page: Audela is a free and open source astronomy software intended for digital observations (CCD cameras, Webcams, etc.). Audela is fully customizable and reprogrammable using simple Tcl-Tk scripts. It enables not only camera control, but also full telescope control, locally or at long distance via a network. It has been written for both Windows and Linux platforms and is available in 6 languages (fr,uk,es,it,de,dk). See [L5 ]
