The collected works of barefoot

I am interested in what other Octane MXE owners deem is the most optimal movie size for gl2 playback using mplayer. I can't seem to get mplayer to playback with gl2 on large movies, and am guessing it's lack of tram? (Octane has 8MB?)

Below are my result so far

720x480 X11 - OK
720x480 gl2 - Not OK (not enough tram?)
576x324 gl2 - OK, quality low when full screen zoomed

Also, I don't seem to have man pages for mplayer, how do I install it?

TIA

i have an r12k 300mhz and i am about to get an MXI. i was kinda hoping mplayer would be ok under that setup.

Dual R12k 300Mhz, if it's any consolation, the Octane audio is amazing! (using mplayer of course)

I used to watch movies fullscreen just fine on my octane with just SI+Tram. What mplayer command line are you using?

If I recall I used either gl or gl2 for the video out...command line was something like

mplayer -vo gl -ao sgi -zoom -f moviename
However, for 720x480, it would need a texture sized at 1024x512, which at 32bpp would end up being 2mb, and that should fit. I know that gl2 uses multiple textures, try the standard gl plugin and see if that runs better?

I was using:
mplayer -vo -gl2 -vf format=RGB24 name.avi whiich does not work with 720x480 movies.

With:
mplayer -vo gl -ao sgi -zoom -f name.avi
I get errot:

BTW what does the -f switch do and what does the -ao switch do. Sorry but I don't seem to have any documentation and I don't know how to install the man pages(if it exists).

Some (mostly high res/high bitrate) files don't display on mgras with 4MB tram.. vo_gl2 only gives a still image, vo_gl only a blank window iirc. I didn't look deeper into this one but I supposed it was a texture size issue too.. given that it only appears with quite heavy files and odyssey and o2 don't show this behavior. Sorry to be not of much help here

-f is non existant -ao selects the audio output plugin. The manpages are included but as I chose to install to /opt/mplayer they are not in your $MANPATH. So include /opt/mplayer/man in your $MANPATH or read it with man -M /opt/mplayer/man mplayer

so long,
Timo

Timo,

Thanks, much reading ahead , is the location of man pages defined at startup somewhere? (so I can just add /opt/mplayer/man to it)

Thanks also for your port of mplayer, great job!

In case anyone else is interested, I've experimented with various resolution and bit rate, with a dual R12k 300 MXE 2Gb Ram and R10K drive setup I get the following optimal resolution:

672x378 with a bit rate of 3612kb/s - gl2
720x480 " " - X11

I have an mpg of gr_osview running on the second head (gl2 playback) and can put it up if anyone is interested (2.5MB). It shows mplayer using one CPU only most of the time and it is really maxed out. It also shows the gfx load is never more than 40% (which is good to know, and confirms that amount of trams being the only limitation to higher res. playback).

I know that SGI doesn't support MXE+ SE with Tram, but has anyone here tried running with trams on both heads?

If yes, what additional cooling did you used to keep it cool.

It is winter where I am at the moment with temps around 7-10 degrees C at night and sometime my office with Octane going and no heater is warmer than my living room with a 2Kw heat pump going

500 bucks is peanuts for big biz - but a lot for an hobbyists budget.
And before I go to buy I´m first trying all the expertise at nekochan here

In the mean time I found another program - all by myself - that does the trick even in demo mode:
Deep Exploration on http://www.righthemisphere.com (a lot of 3D stuff there),
but I dunno if there is an IRIX versions (assumeably not - sigh).
Unfortunately their site appears seriously mangled when viewed with mozilla firefox - checked with IE only? Bad sign.

C´mon, anybody a free solution on IRIX?

If you didn't need to do it on Irix, Accutrans is only $US20 and there is a 30 days trial version available.
Link is here:
http://www.micromouse.ca/

I haven't really used it that much so I don't know how well it worked, but it converts to obj perfectly. I sent away the registration form but never heard from them and CC not charged either. The 30 days trial also lapsed without loss of functionality. Unfortunately I've deleted it now so I can't tell you how well it converts to lightwave.

Cheers

You may consider sending all the unneeded ones cod to me I once did something similiar sending several sets directly to the trash can ... after I learned that a lot of people are looking for them I could have kicked my own butt

Unfortunately they are the company's property, we are allowed to trash'em, but not sell/give them. In any case, I'm pretty sure everybody downloads them from support.sgi.com, no?


Jason

It's a real hassle to turn them into bootable cds though (assuming one has a compatible cd writer to start with).

I usually find it faster to do netinstalls, no time spent reading the CDs, and inserting 10+ CDs in a particular order...


Jason

For people with no compatible network, the cds are much desired. I think the point brombear raised was that some people do find CDs valuable.
