Hi everyone.

Here is my question.
I am developing a java application, that plays mp3, avi, etc.....
So I choose jvlc, because is cross platform, so I am developing the app in netbeans plus windows, but the actual app will run in linux.

So I downloaded: http://trac.videolan.org/jvlc/wiki/download, and make this .bat:

Code: Select all

java -cp jvlc-core-0.9.0-SNAPSHOT-20080727.jar org.videolan.jvlc.example.VLCExample c:/temp/1.mp3

And this is the result:

Code: Select all

>java -cp jvlc-core-0.9.0-SNAPSHOT-20080727.jar org.videolan.jvlc.example.VLCExample c:/temp/1.mp3

[00000001] main private error: interface "hotkeys,none" initialization failed
... done.

I have already copied the plugins directory.
Here is a screenshot of my jvlc lib path:

Thank you for your help, in advance.

I am replying myself.
Just in case someone have the same error:
I made a change in the .bat file, and added two args to the player:

Code: Select all

java -cp jvlc-core-0.9.0-SNAPSHOT-20080727.jar org.videolan.jvlc.example.VLCExample c:/temp/1.mp3 -vvv "--plugin-path=plugins\\"

Now the error changes to:

Code: Select all

>java -cp jvlc-core-0.9.0-SNAPSHOT-20080727.jar org.videolan.jvlc.example.VLCExample c:/temp/1.mp3 -vvv "--plugin-path=plugins\\"

So my guess is, try libvlc 0.9.
If someone comes with other solution, please post it.

i have the same problem and I was trying to get it work here:

viewtopic.php?f=14&t=47912

i tried it with my guide, compiled everything again from scratch and frustration goes on:

Code: Select all

and I get same error with the binary distribution.

check out for a working eclipse way (u have compile jvlc there urself)

viewtopic.php?f=14&t=47912

this is not a solution for the ?not working? binary package!

btw to the OP posting, when you add arguments as mentioned in crosspost to the vlc example the error looks like this, it actually gives an error of libvlc.dll although this file IS there:

Code: Select all
