Hello William,
That is why I stated "(if the player supports it)"
I don't see how the Sun Ray people can fix this since it seems to be a
player problem instead of a Sun Ray problem.
The only way is that (Open) Solaris developers will adjust all players
in the OS to work with Xvideo en Xvenc.
Kind regards,
Ivar

As far as I know, that isn't exactly true. Yes XVideo and XVEnc are
available, but there are no UNIX apps that use the XVEnc API at this point.
Windows multimedia redirection is just using XVEnc to send video to be
decoded on the DTU. UNIX apps are using either XVideo or normal display
updating, not XVEnc. Flash on UNIX isn't even using XVideo but because the
Sun Ray protocol itself is already pretty efficient, you may get pretty
decent results anyways. But if you compare the bandwidth usage of Flash on
UNIX and Flash on Windows with MMR, you'll notice the former is much higher
because it isn't decoding on the DTU, it's just sending frames. In that
way, the Sun Ray firmware doesn't have to be updated for Flash 10, as long
as the browser plugin works, the Sun Ray will be able to show it too.

Subject: Re: [SunRay-Users] Multimedia on Solaris or Linux?
Hello Ken,
As I understand it:
Sun Ray 2 hardware has more processing power than the Sun Ray 1 based
hardware.
The Sun Ray 4.2 Server software and firmware utilize these extra
resources to accelerate some multimedia formats.
This is done with X11 and X11 extensions: Xvideo and Xvenc.
Especially the multimedia extension Xvenc (used for video streams) can
only be used on Sun Ray 2.
Since the Unix environment uses X11 and these extensions natively. all
these acceleration functions are already available in Unix. (If the
player supports it)
The Windows multimedia redirection was needed because rdp lacks the
ability to provide synchronized audio and video.
So the SUN multimedia redirection software in Windows puts the video and
audio in rdp channels which are mapped by uttsc to the available X11
extensions already available in (Open) Solaris and Linux.
So there is support for Multimedia enhancement in Unix already.
However Sun marketing focused only on the new Windows features and did
not mention the work which was done in Unix to make these features work
for Windows. ;-)
So with SRSS 4.2 on Opensolaris build 127 I have the same flash
performance as I have from Windows with the MMR software installed.
Well...In real life it it even better under Unix since flash 10 content
works.
The MMR software in Windows does not support Flash 10 content yet and
this give sometimes unexpected results on websites with Flash 10 contect.
