To be honest, I am not, I am just applying for a ocio display to the source
file. For some reason it behaves different in pngs and jpgs.
The main question is why is there a difference between those 2 extensions and
why does it require a sRGB colorspace by default, because if the OCIO doesn't
have it, it should look for a role but not raise an error.

I defer to OCIO experts on the details, but yeah, if you're just trying to get
it from sRGB into ACES, then I believe it's generally --colorconvert that you
want to use, not --ociodisplay.
So something like
oiiotool my.jpg --colorconvert srgb_texture acescg -o acescg.exr
Also, you can use --autocc to do it all automatically upon input and output, if
your studio has a convention of embedding your color space namesake in your
filenames!
oiiotool --autocc my_srgb_texture.jpg -o my_acescg.exr

Ah, ok. Sorry, I misunderstood your question.
What colorspace does the source jpg have?
And is your goal to go from that colorspace to aces?
Have you tried just using the --colorconvert option?
--colorconvert SRC DST Convert pixels from 'src' to 'dst' color space
(options: key=, value=, unpremult=, strict=)

Agree Daniel, the issue is that if I don't specify the colorspace it is asking
me for sRGB by default, and even if I add iscolorspace or colorspace convert
for some reason it still asks to have sRGB in the ocio config.

I use Output - sRGB a.k.a out_srgb for sRGB and it gives a nice result.
Please note that it behaves a bit different than sRGB in nuke for instance. It
doesn't clip.

if you do
oiiotool --help
can you reply here with exactly what it says in the section that lists
"OpenColorIO", "Known color spaces", and "Known displays"?

Is there no color space in your OCIO config that is approximately sRGB? Nothing
appropriate for video display?

Can you show us the oiiotool command line, so we can understand exactly what
commands and arguments you're using?

Hello!,
I am currently using OIIO 2 with OCIO support, recently I began to transform
some JPGs but as we are now working with ACES, we don't have sRGB as a
colorspace in our pipeline, so I am having an error when trying to convert JPGs
oiiotool ERROR: ociodisplay : DisplayTransform error. Cannot find
inputColorSpace, named 'sRGB'.
My workaround is to duplicate an alias srgb_texture and call it sRGB in the
OCIO config but I wonder if this is something that can be changed? so it
doesn't rely on that specific colorspace for a JPG.
Also ,I am using a 2.0 version, so not sure if this has been changed in a newer
version.
Cheers,
