Issue with OpenImageIO Buffer when Running

[ArnaudJalbert]

Hello!

We were able to build and run toucan inside Linux(Rocky8.9). However, we are currently having issues when trying to render an OTIO timeline. It looks like an OpenImageIO buffer error is raised when a Gap or an effect is encountered by the tool. This does not seem to happen on Mac, only on Linux. Anytime a gap is encountered, this error message is printed out:

An ImageBuf was destroyed with a pending error message that was never retrieved via ImageBuf::geterror().
This was the error message: jpeg image resolution must be at least 1x1, you asked for 0x0

It looks like OpenImageIO is trying to write a frame but since it's a gap there is no data to write.

For example, when trying to write Transition.otio with command toucan-render ./data/Transiotion.otio test_toucan.jpg will yield"

0/10

1/10

2/10

3/10

4/10

5/10

An ImageBuf was destroyed with a pending error message that was never
retrieved via ImageBuf::geterror(). This was the error message:
jpeg image resolution must be at least 1x1, you asked for 0x0

6/10

An ImageBuf was destroyed with a pending error message that was never
retrieved via ImageBuf::geterror(). This was the error message:

An ImageBuf was destroyed with a pending error message that was never
retrieved via ImageBuf::geterror(). This was the error message:

8/10

An ImageBuf was destroyed with a pending error message that was never
retrieved via ImageBuf::geterror(). This was the error message:

9/10

An ImageBuf was destroyed with a pending error message that was never
retrieved via ImageBuf::geterror(). This was the error message:
jpeg image resolution must be at least 1x1, you asked for 0x0

Here, it looks like toucan fails when it encounters the transition effect. Running the Gap example, we get a similar error:

toucan-render '/home/ajalbert/workspace/toucan/data/Gap.otio' test/test.jpg
0/9
1/9
2/9
3/9

Would happen to have an idea why this would be happening on Linux only? Maybe there is a difference between the OpenImageIO API on Mac and on Linux?

Let me know if you could help us and if there is anything we can do!

Thank you!

Maybe it is not finding the plugins; could you try running the command with the "-v" (verbose) flag?

[ArnaudJalbert]

Hello @darbyjohnston ! Thanks for the tip I will try that today!

[ArnaudJalbert]

Hello @darbyjohnston ! When I run the command with the verbose flag it looks like the logs are indicating that the plugin is found correctly:

toucan-render -v '/home/ajalbert/Desktop/test_otio.otio' ./Desktop/test_toucan_arno/test.jpg

Sorry, I need to make the language more clear, it looks like the plugins are missing. If it finds the plugins it will print each one like this:

toucan::ImageEffectHost: Loading plugins...

toucan::ImageEffectHost:     "fromspace": OfxParamTypeString
toucan::ImageEffectHost:     "premult": OfxParamTypeBoolean
toucan::ImageEffectHost:     "tospace": OfxParamTypeString

It will search for the plugins in directories relative to the binary. Do you see the "*.ofx" files in the "lib" directory?
