how complicated is it to use JVLC?

[00se7en]

i have a swing app and would like to add a video panel. jmf sucks so i found jvlc. the problem is that it seems too complex to set up. is it possible to use jvlc by just adding a jar file and a dll (this is my only experience with using external windows libraries). i might be too much of a noob to handle jvlc otherwise, but someone please tell me if this is the case. btw, i would like to import it into an eclipse project if anyone has done that...

There's more than 1 jar and 1 dll: there's 1 jar, 2 dlls (3 libs on linux) and several plugins (more dlls). To chain everything this should be your project layout (on windows):

projectRoot/jvlc.dll
projectRoot/libvlc.dll
projectRoot/org/videolan/jvlc <- you may jar this up
projectRoot/plugins

If you download:

http://jvlc.ihack.it/releases/jvlc-0.9. ... -win32.zip

you will find all the needed libs. If you want to move things around, use -Djava.library.path to point to jvlc.dll and libvlc.dll and initialize JVLC using the --plugins-path switch to make it point to plugins.

thanks for the tips!

i seem to have the project set up fine now, but no video gets played. i dont get any errors in the console either, though. the jvlc panel shows up black for a short period of time, or it launches another directx output window for a short time. i have tried the swing example that was posted on the jvlc site and i also tried some code that i wrote myself. both had the same problem of not showing any video.

my code:

Code: Select all

import org.videolan.jvlc.*; import javax.swing.*; public class Test extends JPanel { private JVLCPanel jp; private JVLC jo; public Test() { jp = new JVLCPanel(); this.add(jp); jo = jp.getJVLCObject(); try { jo.playlist.add("file:///a.mpg", "a"); jo.playlist.play(); } catch(Exception e) {e.printStackTrace();} } public static void main(String[] args) { JFrame f = new JFrame("Video"); f.add(new Test()); f.pack(); f.setVisible(true); } }

any ideas what is going wrong?

i copy and paste the code in a new project in eclipse. I got Errors but when i execute the project i got these errors :

Code: Select all

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jvlc in java.library.path at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.loadLibrary0(Unknown Source) at java.lang.System.loadLibrary(Unknown Source) at org.videolan.jvlc.JVLC.<clinit>(JVLC.java:36) at org.videolan.jvlc.JVLCCanvas.<init>(JVLCCanvas.java:47) at org.videolan.jvlc.JVLCPanel.<init>(JVLCPanel.java:42) at Test.<init>(Test.java:10) at Test.main(Test.java:21)

do you have na idea ?

Give the -Djava.library.path=/PATH_TO_JVLC option at the java cmd. So if you have the jvlc.dll in C:\jvlc, you will launch:

java -Djava.library.path=C:\jvlc yourJavaClass

[jojosucks]

I did the changes. I got errors tough :

Exception in thread "main" java.lang.NoClassDefoundError


and if i put the dll files in the same directory than my .class I got :

[00000001] main libvlc error: no memcpy module matched "any"
[00000008] main interface error: no interface module matched "hotkeys,none"
[00000008] main interface error: no suitable interface module
[00000001] main libvlc error: interface "hotkeys,none" initialization failed

This issue has been addressed several times on the forum. When you initialize the JVLC object pass the arguments --plugins-path=location_of_the_plugins_folder

[jojosucks]

When you initialize the JVLC object pass the arguments --plugins-path=location_of_the_plugins_folder

you mean in the code when I instanciate the JVLC object ?

[marcuschan]

my 2cents if u haven't solved the problem ..

try putting everything under your prject folder :

.\xxx.java <-your java src
.\xxx.class <- your class file
.\plugins\.. <- the vlc plugins folder
.\org\videolan\jvlc\*.class <- the jvlc classes
.\*.dll <- the 4 related dll for jvlc
.\run.bat

in your run.bat,
java -cp . -Djava.library.path=. xxx

hope this may help ...good luck..

Hi,

I have been running inside of eclipse for a couple of weeks and have a example running outside of eclipse. I still have the video playing outside of the canvas and not sure why.
I copied all the modules dll's into a plugins directory inside my eclipse project and put the jvlc.dll and the libvlc.dll at the same level as my class with my main method. Then I passed the argument --plugin-path=dir for the run configuuration where dir points to the plugins folder with the dlls.
That works for me.

Beware the nightly builds do have issues (expected for nightly I guess) and I would run under windows xp and .mov and mpg files work so far but not avi or flv. there are probably other file types that may have issues but not sure what since I have not tested beyond what I menioned above.

Good luck it was a interesting learning curve but patience helps.

[marcuschan]

most likely u need to add the pack() in your code somewhere after the jvlc is constructed and play ...

good luck ..

Thanks and I tried your suggestion but it did not work. Idea appreciated.

Hello,

I have the same issues here.

I have tried several builds of JVLC, and tried to use JVLC in both Eclipse and Netbeans projects...

I am unable to get the bindings to work.

Every time I launch my project, I get this error :

I've tried all the solutions I've found in this forum and others, but still can't use JVLC under Windows...

Any help would be greatly appreciated.

Thanks in advance.[/code]

Hello.
I'm trying to open a MP4 player in a full java application by using JVLC.
It works fine, except that I can't get JVLC to run the player inside my JPanel : it always open a new window in which the video can be seen.
Is it possible to really integrate the player in my own window hierachy??
