[This will probably not be easy to solve.]

I have a new installation of 8.0-release (i386) and a Philips-based
Creative Labs Webcam Pro Ex. The pwc driver was compiled from the port
in the distribution.

With Ekiga (installed as a package during the OS installation) I get
sound, both input and output, but no video. The echo test works. This
is an application that was claimed to work with pwc at a Website
devoted to that driver: http://raaf.atspace.org/

When the Webcam is used with mpeg4ip, built from the port, video clips
can be made. (The command is "mp4live.") Oddly enough, though this
application is supposed to be "experimental," it works fine.

There seems to have been much interesting work done in February 2010
to get Webcams working with Ekiga in FreeBSD, judging from the
messages on the freebsd-multimedia list. I do not have much experience
as a developer, but if someone could refer me to experimental code or
sources of information on this subject, I would appreciate it. The
ports collection of the release version does not have, for example,
webcamd, though it is used by those attempting to get Ekiga to work.
