Using Octane Compression with VPro graphics

The Octane Compression option is *not* offically supported with VPro graphics. I ran down the necessary info to get my V6 equipped Octane running with an Octane Compression board from the following sources:
Techpubs Document
Ian Mapleson's nekochan post
ZoontF's Nekochan post
Chris Pirazzi's Lurker's Guide to Video

For future reference, here's a condensed version of of the process I followed:

You'll need to install the drivers and software necessary to use the Octane Compression <I did this before installing the hardware>.

To install, you'll need the base driver install, "Octane/Impact Compression for IRIX 6.5, p/n# 812-0622-002 <I found a copy on the old web site>. You *must* also install the version of the drivers that came with your overlay set <e.g. 6.5.xx>. These can be found in the "unbundled" directory of your overlay install set. If you're not sure which CD they reside on, take a look at file:///var/www/htdocs/WhatsNew/install/cds_frame.html on your system.

Remember, if you have a VPro graphics option installed, IRIX thinks VPro and Octane Compression conflict, so you'll have to use "rulesoverride" to get the drivers installed:

Code: Select all

Controls whether conflicts can be overridden. The default value, "off", prevents you from installing subsystems that do not meet specified incompat
or prereq rules. If you want to override these rules, set "rulesoverride" to "on". This preference should be used cautiously. "rulesoverride" is not
saved from session to session. NOTE: it is best to first resolve as many conflicts as possible, and then only as a last resort use this preference
just before "go" or "start" to overcome the remaining conflicts. After the installation completes, you are advised to set "rulesoverride" back to "off"
so that conflicts do not go accidentally unnoticed for the remainder of the session.

If you use Software Manager, rulesoverride can be set from 'File'>Set Preferences' on the toolbar. The rulesoverride setting is transient, but just to avoid problems, I'd confirm it is not longer set when i'd finished with the Octane Compression driver install.

This Techpubs document lists the following software subsystems and prerequisites for Octane Compression:

As root, edit "chkconfig" and set the configuration flag for the video daemon to "on":

Code: Select all

# chkconfig videod on

And either reboot or load the video daemon manually:

Code: Select all

 /etc/init.d/videod start

At this point you should be able to display a live video feed in a 'videoin' window.
