Not trying to flame just educate. Conversation is always good.
What I would ask is how does one manage thousands of those devices that
"boots a Linux 2.6.12 kernel". Sun Rays take a different approach.
Zero admin of the desktop, and 100 percent server based computing.
Somethings, such as video, are just not going to work as well. Not to
say we're not investigating how to make it better.

I'm not sure about a 100Mhz PC but its running on these 200Mhz units -
but whether that includes video I'm not sure

As for the details this article explains the approach to X compression
http://www.nomachine.com/documentation/html/NX-XProtocolCompression.html
Again, I realise I could be getting close to being flamed for suggesting
something that I don't know a great deal about but I thought it worth
pointing out in case the Sun engineers are looking for ways to reduce X
traffic and had perhaps not heard of the techniques used by this company

Exactly. The Sun Ray only has a 100 Mhz processor. Find a 100 Mhz PC
and try to 1) load and OS on it and they try to run NoMachine on it.

Perhaps it should be renamed to "OneMachine"?

How much of an OS do you need to use Nomachine?

I know I've mentioned this product before but the video output on
NoMachine NX (http://www.nomachine.com) is very good. I'm not sure
of the scale of rework involved (or any other compatibility issues
for that matter) but I would guess the same thin client compression
technology on Sun Rays could maybe solve a lot of these bandwidth
problems

Video is not a wonderful user experience on any true thin client
I've tried recently. Anyone who's rendering all their video on
the server is going to run into issues. Full screen video simply
isn't Sun Ray's target market.
What Sun did with Sun Forum, as I understand it, was to make it
work better with Sun Ray by having it bypass the X Server and talk
directly over the wire to the DTUs.
Craig Bender can probably provide a bit more technical detail!

To summerise:
Video is crap on Sunrays...
So, how did Sun make it work with their video conferencing tools?
Does anybody have any results using this?
Thanks,

got mythtv running on a sunray this weekend if the window was

I have tried VLC and Realplayer, they both work ok with very
small video windows (i.e. scaled down) but anything larger just
sucks. It'd be cool if there was some magic that detected video
and did something even more magic to make it just work nicely.
That way you;d not need a special video player to play video to
a SunRay, it'd just know that this screen area was rapidly
changing, assume video and the rest would be magic.
/me orders one bag of magic pixie dust from Ebay

Hi,
I have been playing with video on SunRays over the weekend.
Server is a MSI K8 Neo2 FIR MOBO with a 4800+
dualcore 2.4 GHZ Athlon64 cpu
and 1 GB RAM.
Solaris 10u1 with SRSS 3.1 is installed.
Companion CD is installed.
I downloaded the Mplayer 1.07try2 source and built it with
/usr/sfw/bin/gcc -mtune=k8 -march=k8
Downloaded a bunch of codecs and built it so it Mplayer can
play
MPEG , Windows Media, Real media and LIVE streams.
Downloaded the MplayerPlugin for mozilla and friends and
Gmaked it.
Also compiled in Xvideo support to run on the Nvidia VGA
screen.
Doesnt run on sunrays though. Xvideo in fullscreen mode on the
Geforce6800 is cool ;- )
Of the output formats that Mplayer supplies it seems that
SDL is the only one
that runs on SunRay. Xv, x11 ,or openGL does not work for me.
After deployment of the MplayerPlugin I can play video-on
demand streams from
cnn.com and cmt.com on the sunray. both of these are
in Windows Media Format.
This would not work on a SPARC platform I suppose because of
the X86 codecs.
When I play a video stream from www.cmt.com I seem to use
about a fifth of a CPU.
so theoretical maximum on this PC server would be 10
concurrent sunrays using video.
This should translate to 15 -18 concurrent videos streams
on a X4200
I begin to see why people on this list are moaning about
video performance :-)
How does this result compare to yours ?
Regards
Lars Tunkrans
