Hi Everyone,

Just released a new beta version of my flipbook player and imaging utilities. There are lots of changes in this version, the main one being a new OpenGL accelerated imaging pipeline which should provide some nice speed boosts. Image I/O performance for uncompressed DPX and Targa files has also been improved; I would be very interested in any feedback from people using SANs or RAIDs.

Homepage: http://djv.sourceforge.net/
Downloads: http://sourceforge.net/project/showfile ... _id=118244

Couple of notes:
* Graphics hardware with texturing is now required to run the flipbook player.
* OpenEXR files are no longer supported with IRIX.
* IRIX QuickTime support requires the libiconv package from Nekoware.

Thanks!

got it right away, thanks!

Just curious - why did OpenEXR support drop?

Because OpenEXR is no longer supported on IRIX?

Is there a way to download the older version so you could run it on hardware without texturing? I didn't find it on the site...

Sure, the previous versions are all on the Sourceforge downloads page. If you scroll down to the bottom of the page, you'll see '+' next to 0.6.1 Beta and 0.6.0 beta - just click on the '+' to show the download list for that version.

I'm now using OpenGL for all the image processing which ties the software capabilities to the hardware, and unfortunately I don't think SGI graphics hardware is capable of processing HDR images (*). Floating point color values get clamped to 0.0-1.0, and there's no support for shaders which are needed for the OpenEXR color correction. I'd certainly be happy to be proven wrong though.

On a positive note, regular images fly on my Octane 2 system. Uncompressed Targa and DPX files can be mapped directly to OpenGL, so there's almost no overhead when loading them.


(*) At least the older SGI graphics hardware I have access to.

Ah okay - thanks for the info I'll try and update the blog page with this update sometime today.

Hmm, so, is my excuse that my monitor is locked to 800x600? Or the default "open in new window" is 640x480? Or that in either case, I'm incapable of seeing/using a scroll bar? I swear it wasn't there before!

Thanks for pointing out the obvious, neko, some of us seem to need it sometimes...

while using the open-file window i get console errors anyhow it seems like they don't affect the app


btw could you add that the extension 'sgi' is recognized? since rgb file work i guess it won't be much work

Don't worry; I wouldn't forget something like that.

It should recognize images with the .sgi extension fine... I think something is going on with the offscreen-rendering that generates the image thumbnails; that's what's causing the GLX errors. Do you see other image thumbnails in the file browser? Also, what sort of hardware are you running?


Thanks, Darby

no, i don't see thumbnails at all. i tried it with an ir2e

Hmm... Something's definitely wrong with the offscreen-rendering then; I'll try and add some options to the next version for selecting different GLX visuals. Thanks for the feedback.

you're welcome. i'm gonna try some more specific tasks if you like. just let me know

I've downloaded the latest version of the fabulous djv player and when I
tried it on a bunch of targa's I get the folowing Error:



Does this mean my Octane 2 V10 Isn't qualified anymore ?

Also after I start the program on the commandline I get the following message on the same line :


What could this mean ?
