I am interested in working with live Video in an X window. I have
heard that there is a document describing some video extensions to
X, but have not been able to find it. If anyone can supply me with
more information about this, I would appreciate it.

In X11R3, check out the code in server/ddx/plx/.

This sounds like Todd Brunhoff's work on VEX, Video Extensions to X, at
Tektronix. You can find an article on VEX in the October issue of UNIX
Review magazine.

I've had a color DS2100 for a couple of weeks now and am still shocked
and horrified by the default colors in the rgb database. The "pink"
color in particular looks like the flesh-tone of someone who has been
puking for several hours and would really rather get a bullet in the
head than go on living.

It seems to me that the vendors (e.g., Digital) who ship canned X systems
should be tuning the default, named colors to look as good as possible on
their machines. Or is it just the case that these colors look awful on
everyone's system and (in this case) Digital decided to go for compatibility?

What do you say? Does your "pink" look as bad as mine? Do you normally
whip up your own color table entries and ignore these default colors?

At the last SIGGRAPH, there were several companies showing video
products for X, including Parallax, RGB Systems, and Tektronix. There
are several different X extensions to support video. Parallax and
Tektronix are proposing their versions as standards. You can probably
get drafts from those companies.

And is there any documentation on the library calls? They look
pretty obvious, but most tricky things do...

I read some place that these colors were supposed to have come from the
DEC-240. Anyway, the MIT-supplied values for named colors didn't look very
good on our SONY monitors, either. Therefore, as an X-server developer for my
employer, (Tektronix, Inc) it was my responsibility to do something about it.

Advised by our human factors folks that "standard" named colors exist, but
only for well-controlled color coordinate systems (like CIE, but not for RGB),
I sat down one evening with the handiest standard of subjective color names,
a box of 72 Crayola crayons. (Believe it or not, over 50% of the colors from
rgb.txt were represented.)

Using an X-client implementation of the TekColor model, I created the following
list of named colors. Appearance on your monitor may vary because of brand,
age, and video drive circuitry, but I think you will find it a better match
for the average monitor, than the original rgb.txt file from MIT.

I'll second that! And if they wanted to be _really_ nice they could submit the
tuned rgb databases to MIT so they could be distributed with the MIT software.

Flames to /dev/null, please.

You are all right. We just updated the monitors recently and they have
quite different
characteristics than the previous (not that the database was all that
good for them, either).
I tried pink on the VR299 I recently hooked up to my PMAX and it is
pretty hideous.

We are working on fixing this.
