I noticed that aswell. It shouldn’t be a thing but I don’t know why there’s two slashes…
I also don’t know how I could change that (or if thats even possible)
Thanks for trying though: bear with me as I try to understand and keep up.

I’ve read somewhere that it _could_ be a 32/64bit issue. But how to fix it; that I didn’t find.
Thanks anyway @kll

Mhmmm… The ‘gstreamer-java.jar’ file was exported correctly though, its in the contents. Could it still be missing parts?

Were you able to resolve this issue?
Just to confirm: this is a problem with exporting the Processing Video library on the same machine with the same camera – you are able to run the sketch in PDE and it runs fine with video, but when you export and run on the same laptop it fails. Is that right?
You may need debugging advice from video library gurus.

Exactly right.

I’m not sure why that would be happening. Sounds like we need some video library / GStreamer experts to weigh in on this.
Perhaps @hamoid has a suggestion for how to start debugging…?

I don’t own a Mac, but the first thing I would try is to make a minimal program that shows this issue. Maybe the video playback example that comes with the library shows this problem already when exported as an application?
ps. @neilcsmith is the gstreamer expert here 🙂

I have tried setting up a minimal program and exporting it. I can successfully export a program that includes the opencv and video capture library (and the facial recognition works).
Could the _contour_ function from opencv be the one causing the problem?

Thanks @hamoid 😜
That plugin error message in the first post definitely looks suspect, particularly with the empty folder name `Java//plugins`. I do wish the Video library just went with a system installed version of GStreamer - be so much easier! The way the code currently looks I don’t think it’s even easily possible to set it to use one.
You might want to look at Video library v2 and see if that’s any better. At least anything with `gstreamer-java` rather than `gst1-java-core` in it has not been supported for years!

Have you with tried v2, @has_sanity ?

Yes, although that’s also a bit old - we’re about to release gst1-java-core v1 which has a lot of fixes in it. I’m hopeful someone will pick up the Processing Video library for GSoC!
A key change since the Video library was first written is that the GStreamer project now releases Mac and Windows installers which makes things far easier if you don’t need to bundle the library for any reason. I think that should be the default for Processing. I just checked the v2 code though and it’s doing things to explicitly disable a system install except on Linux.

Just really quickly tried (have to be somewhere lol) and got this. Idk if it’s because of changes to the library which I missed, but posting it regardless because I’m lost.
```auto

@hamoid @neilcsmith
It’s not really a must to find a fix for this, but it’d be really sick if there is a fix for it. I’m using it for an art project (uni), being able to export it properly would just make a few things easier. Thanks already though
