Tcl interface to UVC cameras using
libusb. It may run on Android devices,
however, many devices with ARM processors seem to have problems with
isochronous transfers in their USB host implementations. The effect is
usually that no image data can be read from the UVC camera, ever.
Support on other platforms varies, too. It is known to work on x86(_64) Linuxen, MacOSX, and maybe FreeBSD and Haiku, but these are untested.
