Issue loading from python script

[efleurant]

Hi,

I'm trying to load a exr sequence with a python script using the -pythonScript argument, but it ends up crashing (segfault ). If I run the snippet from mrv2's python console though, it works as expected. Here's the code snippet:

import mrv2
from mrv2 import cmd, image

mrv2.image.setOcioIcs("ACES - ACEScg")
mrv2.image.setOcioView("Rec.709 (ACES)")
mrv2.cmd.open(filename="/path/to/my/sequence/my_shot_name.000100.exr")

Note that /path/to/my/sequence/my_shot_name.000100.exr being the first frame of my sequence... in the UI that seems to trigger the whole sequence. I tried using the standard sequence pattern ("%06d", "######") but those didn't work.

Here's the error I'm getting when running the above code with through the -pythonsScript:

GOT SIGNAL 11

Am I missing something? thanks in advance...

Hi, @efleurant! -pythonScript currently runs without a UI so any loading of an image that tries to play it back will currently lead to a crash.
What's your use case scenario? Do you want to bake-in OCIO transforms?

@efleurant I added the functionality to support most python commands using -pythonScript. Please download v1.1.9 beta and give it a try from:

https://sourceforge.net/projects/mrv2/files/beta/

I tested with the built-in OCIO studio config and this script:

#!/usr/bin/env python

import mrv2
from mrv2 import cmd, image

image.setOcioIcs("ACEScg")
image.setOcioView("ACES 1.0 - SDR Video")
cmd.open("/home/gga/Pictures/Mantaflow_v09/Fluid.0001.exr")
cmd.save("/home/gga/Test.mov")

I noticed save uses "file" instead of "filename" so I changed that in the api.
