Re: A simple question About OIIO and OCIO

Jeremy Selan <jeremy...@...>
 

Sorry for the delay.

Yah, oiiotool is definitely your way forward.

There currently isnt a way to apply .cc or .ccc grades, except using ociobakelut (and even then, this just bakes it into another lut, not into an image).

But this is an oversight; we'd love to add an oiiotool --lut and --invlut option.  (or whatever it's called).  Probably wouldn't be too difficult. Probably < 50 lines of code or so.

Alex, any interest in giving it a shot?  If so, I'm happy to sketch out the overall design for what to add where.  If you're not up for it, I'm happy to try and knock it out later this month.

Cool, so oiiotool is considered the way forward then?

Out if interest, do you know if it's possible to apply .cc or .ccc grades via any of the command line tools (ocioconvert or oiiotool)?

I'm tooling around with the possibility of making a web app to apply CDL grades and display EXR frames in a browser (as a jpg proxy).

ocioconvert is a demo app that's not really needed.  if you'd like to do color conversions, we'd recommend installing OCIO, then installing OIIO (with OCIO build-time depencency) and then trying oiio-tool --colorconvert

Ahh! I had no idea OCIO could be installed view brew..
Very neat..
Unfortunately it doesn't build it against OIIO, so its still missing ocioconvert.

But I found my original problem:
Stupidly I was using:
export OCIO_PATH=~/Developer/oiio/dist/macosx
rather than:
export OCIO_PATH=/Users/alex/Developer/oiio/dist/macosx

Thanks again
Alex

Are you on OSX?  Have you considered homebrew package manager?

I've never tried it, but if it works as advertised that would make a system install of OCIO simple.

Was there an easy answer to this?

I'm running into the same problem.
