VLCJVideo update

Other workaround options to explore is to pass a UNICODE (UTF-16) string:

  • video = VLCJVideo(this, u'')
  • video = VLCJVideo(this, (u''))
  • video = VLCJVideo(this, [u''])

all the above fail…T_T

What are the errors for each 1 of those workarounds?
Also, are you using PDE 3.5.4 version?

I’m using verion 3.5.4.

The string and unicode strings gives

TypeError: VLCJVideo.VLCJVideo(): 2nd arg can't be coerced to String[]

The list gives

NoSuchFieldError: SIZE

I also get “NoSuchFieldError: SIZE” when using video = VLCJVideo(this, ())

Something about the instantiation of MediaPlayerFactory inside VLCJVideo’s constructor isn’t working.

It’s failing to instantiate com.sun.jna.platform.win32.WinReg$HKEYByReference or finding the paths for VLC when running under Jython.

So I believe you’re stuck w/ Java Mode. Or you could try out py5, which can also use Java libraries w/ Python syntax:

The Processing Java mode works perfectly fine. I can play the video in Java mode, but I am not able to make the Python mode work.

So, there’s no way to make in work with Processing Python mode?

Not 1 that I know of, sorry. Best bet now is py5.

I also tried, but on Linux not even the library can be loaded.
In short: Python mode is not maintained, so it’s a really bad idea to start developing anything.
