In regards to funky colors: it's odd that green would be left out, since green is in the middle, if it was no blue or no red I'd assume it was was a pixel format issue... I'm leaning towards some pixel format issue or something, I don't know, but really at texture upload time it should do all conversions.

For ultimatevision: screw it all I could write up the color conversion to be done in a pixel shader and it'd be nice and fast :) But really, if you have UltimateVision, you have fast enough cpus to do decoding and it's not an issue.

For O2: Thanks for the compliments, it works well and will likely not get much faster...unless we come up with some faster way to do the YUV planar unpacking.

For pixeltex: It's known buggy, along with multithreading support, and assync drawpixels support. What do you expect, writing code for systems I don't have :)

At this point vo_sgi support will be mostly up to Schleusel/Dexter I have a feeling, as I'm no longer an SGI owner...and probably won't pick another up until after I move in October...so maybe November you can expect new things :)

artherd's got an Onyx up for offers and it's in the Bay Area, too. Multiple cpu's as well :-)

Looks like i've fixed Newport/Express support for MPlayer. I'll be sending a patch to Schleusel today, so he can incorporate that into his future builds. I have tested it on an 8 bit Newport and 24bit XZ Indy and they both produce correct colors. Can't say anything about Elan/Extreme yet, but i venture it will work just fine.

Dexter1 you are unstoppable!

BTW, which of the SGI native format (i.e. things I can export from mediaconvert) will work well with mplayer. So far, Quicktime has given me grief.

A question. Yes, I'm too lazy to look through the source code at work to find the answer.

Is there any work done making vo_sgi support output to YUV video devices? IndyVideo, Indigo2Video for Impact, and MVP come to mind. Is the EVO option take YUV, or is it RGA native? How hard would it be to add?

Also, dexter1 what sort of performance were you getting on that Indy XZ?

I think this would require a plugin of its own, since the current vo_sgi.c code is already a bit bloated. Would eliminate the need for conversion routines, but the exact API's are not easy to code for. And the fact that few people have these boards, well' atleast not the developers, means that it would be pretty hard to come up with support for any of Indigo2Video,Cosmo/Galileo/PVO/DM2 etc. But if anybody is wanting to make me a reasonable offer on a Cosmo2 for my Impact I2, i'm all ears. It's my birthday, y'know :)

http://www.habanera.nl/expertise/images/bullet.jpg is a nice mpeg i used in testing Indy MPlayer support. It takes 12.6 seconds on an R5K180MHz XZ with 6.5.22m. An XL is faster, as expected, about 11.9 seconds. You should also run -vo sgi:rgb for fun, it's dog slow :)
Pity the double buffering visuals have too limited bitdepths, so everything comes out dithered. :(

Which means you could speed it up a bit by disabling dithering at the expense of image quality:

glDisable(GL_DITHER);

Vegac and i know this document by heart, and tried most of the glDisable() switches. :) . The GL_DITHER and other glDisable()'s are in the current vo_sgi.c code already, though doing glDisable(GL_DITHER) would place too severe a restriction on Express machines with larger framebuffers which actually *can* display the proper visuals like Extreme, though i haven't ran it on an Extreme yet (will do that tonight).

Let's wait until Schleusel finds some time to build a tardist with the latest patches. Chances are good that i will have my I2 Extreme running MPlayer very soon

Well' I don't ... and I did found the document recetly ... :)

I tried a number of the options described there but they don't seem to influence the framerate of FlightGear much (at least not on an O2 and an Octane/MXI).

hello,

tried it, too. seems like the mt is working fine but stopping by around 160% cpu usage. can't
this be tuned? ;-)
or real smp??

fps are not that good. used it on an onyx2, 8x250/ir2e. i guess with r12k and up it's very nice!

i'll try to update it this weekend or early next week. University got me back for the moment (preparing for some exams)

I tried the fresh version on the indy yesterday, :abgr works nice now :-) :rgba still gives wrong colors though and the OSD is seriously broken with both :rgba and :abgr

I uploaded an ftr/fti for mplayer... The icon is based on Macromedia's IRIX icon, I think it is pretty appropriate... Drag & Drop a movie on the icon and it plays...
I uploaded it in /incoming, so it's going to be in the download area soon...
For now, check the gallery http://forums.nekochan.net/modules.php?set_albumName=album95&id=Desktop&op=modload&name=gallery&file=index&include=view_photo.php

Quick quizz for the movie buffs: who is the pretty lady in the mplayer window, and what movie is it?

Tom Cruise, I can't remember the movie but was it TopGun?

Don't think that it is Tom Cruise, but his ex - Nicole Kidman.
Movie isn't Top Gun, but not sure what it is...

The icon is nice btw.

Nik.
