>> I like the video too. It looks very promising. The only problem i have
with it is the only thing i REALLY want from it is the menus,
Right now it's probably not that easy. However, KDE has said they really
want to make LinuxMCE the default media desktop. The first thing they want
to do is make LinuxMCE use QT instead of this pluto-customized SDL. It
seems the next QT for KDE 4 should also support the alpha blending. When
doing these changes one goal will be to make the menu/GUI more skinnable and
easily re-used for other apps, so MythTV, or Freevo or anybody else can plop
the GUI into their stuff easier. So hopefully it's coming.
>> Any chance we can plug that navigation system into MythTV? I'm not about
to delete Myth to start again with LinuxMCE, but that navigation system
looks nice. It could to with a couple of theme artists working on it, but
looks very quick to use.
It takes a bit of getting used to the gyro flipping stuff. But I can
honestly say once you get the hand-eye coordination part down it is *sooo*
much faster and easier. And it's good for the WAF too because if she gets
used to it, then a normal x/y grid seems really cumbersome. The theme now
is ultra simple; neutral shading and plain text. That's inherited from
Pluto, because from I understand they do custom UI's for each commercial
licensor so this is just a vanilla reference. I've got no design talent at
all and would love to see how pretty it could be made. Unfortunately I've
played around with the design tool Pluto created, called HADesigner, and
it's really very cumbersome to use. It's an object-oriented UI design and
thus tries to be sophisticated. But it's crude, and would be so much better
if it was more like Macromedia flash's tools so designers could get creative
and not get bogged down trying t learn the tool.
>> I was quite impressed with the video, I plan to try it out sometime, but
probably not until I get a spare system I can try it on without wiping my
current myth setup.
That makes sense. If you can get the DVD installer and have a spare hard
drive, it's only about 20 minutes from the time you put the disk in until
Myth is up if all your hardware is supported. And the existing recordings
could be moved over. But I know the feeling that when something is finally
working right you don't want to touch it.
>> Cool, is this supported on more than nVidia cards now?
Yes, but with a BIG problem... You see those thing clients in the video?
They are pretty slick. They do full HD 1080i rendering and de-interlacing
and the video quality is orders of magnitude better than nVidia's, plus it
does all the alpha blending stuff. But, that hardware is expensive and
those drivers are not free. The manufacturer says they were developed
especially for them by the chipmaker, but they license them. I know there's
some proprietary stuff going on to get it to work. What we really need is a
way to do this with all off-the-shelf hardware. Unfortunately, afaik, only
nVidia's proprietary drivers support alpha-blending for X11 still, and even
then the video quality is not great, particularly with 1080i since nVidia's
not doing de-interlacing. This is a huge problem for Linux as a media pc
platform. I personally talked to both nVidia and ATI about this. In both
cases the response was, basically, "Linux is for servers. Graphics
performance isn't important. 95% of our graphics driver work is for
Windows." What I don't get, and I haven't been able to get an answer on, is
Mac. Doesn't OS X use X11, or something similar? They obviously have good
video drivers. Why can't those be ported over to Linux? Anybody know why
not? Or have any other inside knowledge? Also, what about Intel's drivers
now that they're GPL? I got mixed messages there. At CES someone from
Intel said the real reason was that Intel's graphics business wasn't
profitable and they wanted to pull resources off it so they were "dumping"
the drivers on the FOSS community by making them GPL, rather than engaging
it. However, others have said that Intel is actively pushing the
development of the GPL drivers and that soon they should be a stable video
platform for Linux. Anybody know the truth?
