JVLC .jar for windows

Posted: 29 Jul 2008 23:45

by CamHart

Edit: Read further on to see what I've taught myself in the time waiting for you to reply, however I'm still having problems so don't go away

!

If I'm posting this in the wrong spot I'm sorry, and please feel free to move it. I'm a bit new to this whole thing, probably not qualified enough to be attempting what I'm doing... But I've got the newest .jar file for jvlc downloaded, and I'm trying to get some of the sample code players to run for me but I'm having some problems. My friend says that the .jar file needs to be updated for windows because it's broken atm.

Here's the files I've got.

Complile.bat

Code: Select all

javac -classpath jvlc.jar; *.java
pause

Run.bat

Code: Select all

java -cp jvlc.jar; VlcClient
Pause

VlcClient.java (this is the sample code)

Compiling seems to work just fine. But when I run it it spits out this error

Any and all help is appreciated.

Edit: Okay so I was talking to another guy and he said I needed to add libvlc.dll file to the directory. So I did, and out comes this shibby.

I have never used this module, but maybe you should try to give javac an additional path to search libraries into instead of moving libvlc. Maybe libvlc will search other VLC libraries (at runtime) with a path related to its location (thinking about plugins/*.dll ones).

To do it, try those lines (not tested):

Code: Select all

javac -classpath jvlc.jar "-Djava.library.path=c:\Program Files\Videolan\VLC" *.java

and

Code: Select all

java -cp jvlc.jar "-Djava.library.path=c:\Program Files\Videolan\VLC" VlcClient

You can also try to add directory containing libvlc.dll and/or the plugin folder into PATH environment variable.

Okay so I was fiddling around a bit and decided to download the nightly build (like beta) of VLC Media player. I put that .dll file into the directory instead of the old on and stuff started to run (y). But now i can't seem to be able to open any files and this error keeps outputting.

Code: Select all

--- For the not-last message ---
Have you tried this one ? (after having compiled without my -D.. parameter)

Code: Select all

java -cp jvlc.jar "-Djava.library.path=c:\Program Files\Videolan\VLC" VlcClient

If it works, you can add this option inside your code source (google java.library.path). I have added double quotes because of the space, you can try to mive the opening quote after the '='.

--- For the last message (nightly) ---
- yes, it is better than previous tests
- maybe it can't find VLC "plugin" directory (which contains module libraries for access, codecs and others)
- I find the URL you are opening quite weird : "file://a.mpg". what about "c:\\folders\\file.mpg" or "http://test.tld/fold/file.suffix"?
-> try to add the -Djava.library.path at launch time without using copied libvlc library
-> try to copy all VLC folder to keep names relative to libvlc.dll location usables

Yea I tried it and it wouldn't even open up the program. I moved the quotes around into all positions that could possible make sense. I even installed VLC to a different directory so I didn't have to use quotes. When I did this, this is what the error was.

Code: Select all

Hi guys,

I try it and get success after following fixes:
* use of the same nightly build (20080727) - maybe not critical but version 0.9 is a must;
* add libvlc.dll location in the PATH variable;
* add to VlcClient code to init jvlc with args;
* add to args option "--plugin-path=path\\to\\plugins\\directory";

I build example under Eclipse 3.4 and even place both jvlc.jar and jna.jar into project's lib folder. Later on I place whole VLC staff into project's lib\native folder. Everything works fine even without "-Djava.library.path=..." argument in Run properties.

Code: Select all

        String[] arg = new String[8];
        arg[0] = "-vvv";
        arg[1] = "--intf=dummy";
        arg[2] = "--ignore-config";
        arg[3] = "--no-plugins-cache";
        arg[4] = "--plugin-path=.\\lib\\native\\plugins";
        arg[5] = "--extraintf=http";
        arg[6] = "--http-host=0.0.0.0:9999";
        arg[7] = "--http-src=.\\lib\\native\\share\\http";

        jvlc = new JVLC(arg);

add PATH variable into Run VlcClient as Java Application Configuration Environment Tab

Code: Select all

PATH=./lib/vlc_win32

It is needed by jna to find libvlc.dll in Windows. No other run arguments are needed.I'm not sure why -Djava.library.path=... does not work in a proper way without adding libvlc.dll location into the PATH variable.

It has to be added both jna.jar and jvlc-core-0.9.0-SNAPSHOT-20080727.jar in Project properties in Java Build Path Libraries Tab. It is good idea to put them into project's lib folder but it is not a must.

Unfortunately, it is not the best way because it is needed to put in the code or as run argument location of plugins. Is it a bug (probably for Windows) or it is not implemented in libvlc.dll to find plugins relatively to its own location?

In case of relative search for plugins is solved only PATH should be updated for Windows which is its problem in searching the libraries. No such a problem on Linux if Vlc is installed in a right way (libraries could be found by jna).

It is very important especially when multi-platform plugins for eclipse/equinox have to be developed. Any ideas how to automate jvlc/plugins development in eclipse and in a platform independent manner.

I got mine working in a smiliar way by simply adding

Code: Select all

		String[] args = new String[] { "-vvv", "--plugin-path=g:\\Program Files\\VideoLAN\\VLC\\plugins" };
		jvlc = new JVLC(args); //replacing --> jvlc = new JVLC();
