OTIO loading: question about file reader #124

I have an OTIO file that seems to load ok in XS v2.0.0.dev insofar as building the timeline. However, the file's attributes (those found in the Media bin columns) are all undefined. I don't know to what extent the OTIO loader has been implemented.

(Btw, I was unusure about how the paths should be constructed. So I followed the way an .xst writes the file out, i.e. "file://localhost/disk/..../myimage.{:04d}.jpg")

If I use load media using XS's loading methods (e.g. Add media from clipboard), and then save out the .xst file, I see that my "media_ref" data dict is also filled out properly. The "reader" key reads "FFMPEG", also.

But I load the OTIO and save out the .xst file, the media_ref is filled with zero/default values, and the "reader" key is an empty string.

So, is there a way that I should I write my OTIO file for XS to read it? Or is file loading not fully implemented?

Thanks for reading.

Does the media play that's loaded into the timeline ? Loading otio should be supported including loading / creating of media.
Though I've not tested this outside of dneg.

Hi @alatdneg , no it doesn't actually play.
This is the otio file.

            }
        ]
    }
}

The result is that in Media "bin" I get "undefined" in some of the columns like Resolution, Created, Artist. There is no thumbnail, and nothing can be played.

Btw, the timeline loads fine; I can see the shots lined up properly.

I'm going to double check my OTIO libs to make sure they're in line with XS's.

@alatdneg , thanks for that. I'm going to try out QTs first, and investigate image sequences afterwards.

Hi @alatdneg , I've been able to successfully load QTs via OTIO, but XS 2.0.0dev crashes when I try to view the timeline. This is the OTIO file I'm working with:

The timecode is at 00:00:42:08 which is frame 1016.

When I load this into XS, QT loads. I see the otio file under the Media panel, and I can actually play this QT back in the viewport.

But when I double-click on the otio entry in the Media panel to see the timeline, XS crashes.

If I remove the url from the otio file, and repeat the process, XS doesn't crash; it shows my the timeline with the shot tag starting at 1016.

I've simplified otio file generation to follow the example in https://github.com/AcademySoftwareFoundation/OpenTimelineIO/blob/main/examples/build_simple_timeline.py.

Is there something you can see in the otio file that's wrong? Or any theory why it crashes?

@alatdneg pardon me, yes, there was; I should've posted the first time:

Hi @faulknermano,

If you have the time, could you pull from my fork (develop branch), build and try again. I have just updated my fork to sync with our internal develop branch. Recently I've done some refactoring that might have fixed the bug that you have hit here, but I'm not sure.
Using our latest build I have duplicated your OTIO file above, and switched out the media path for a QT that I have on disk and it's all working as expected.

Just a further note - the latest version requires OTIO v0.17 - I can't remember if that was already the case or whether you might need to update that dependecy when you build.

When we configuring OTIO v0.17, I use -DOTIO_PYTHON_INSTALL=ON -DOTIO_INSTALL_PYTHON_MODULES=ON -DOTIO_SHARED_LIBS=OFF
The reason is that if you build OTIO with shared libs, it installs them to the python install location but not to regular /lib/ path so xstudio can't link to it at runtime unless you do some awkward fiddling with LD_LIBRARY_PATH. Building static libs, however, avoids this problem.
