JVLC Vista

[mkeuschn]

Hello *,

I have compiled vlc(0.9.0) for my jvlc project with following configure options:

Code: Select all

PATH=/usr/win32/bin:$PATH \ PKG_CONFIG_PATH=/usr/win32/lib/pkgconfig \ CPPFLAGS="-I/usr/win32/include -I/usr/win32/include/ebml" \ LDFLAGS=-L/usr/win32/lib \ CC="gcc -mno-cygwin -Wl,--add-stdcall-alias" CXX="g++ -mno-cygwin -Wl,--add-stdcall-alias" \ ./configure \ --host=i686-pc-mingw32 \ --disable-gtk \ --enable-nls --enable-sdl --with-sdl-config-path=/usr/win32/bin \ --enable-ffmpeg --with-ffmpeg-mp3lame --with-ffmpeg-faac \ --with-ffmpeg-zlib --enable-faad --enable-flac --enable-theora \ --with-wx-config-path=/usr/win32/bin \ --with-freetype-config-path=/usr/win32/bin \ --with-fribidi-config-path=/usr/win32/bin \ --enable-live555 --with-live555-tree=/usr/win32/live.com \ --enable-caca --with-caca-config-path=/usr/win32/bin \ --with-xml2-config-path=/usr/win32/bin \ --with-dvdnav-config-path=/usr/win32/bin \ --disable-cddax --disable-vcdx --enable-goom \ --enable-twolame --enable-dvdread \ --enable-debug --enable-dca \ --disable-mkv --disable-taglib \ --disable-optimizations \ --enable-debug \ --enable-qt4

when I try the example provided by the java jar file from the jvlc page, with my own compiled vlc version, I got following error:

Code: Select all

== Starting VLCExample == Creating a JVLC instance with args: 0) C:\11-eclipseWorkspace\test-videos\t-en.mpg Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'libvlc': Das angegebene Modul wurde nicht gefunden. at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:114) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:157) at com.sun.jna.Library$Handler.<init>(Library.java:123) at com.sun.jna.Native.loadLibrary(Native.java:260) at com.sun.jna.Native.loadLibrary(Native.java:246) at at.org.videolan.jvlc.internal.LibVlc.<clinit>(LibVlc.java:41) at at.org.videolan.jvlc.JVLC.<init>(JVLC.java:45) at at.org.videolan.jvlc.example.VLCExample.main(VLCExample.java:29)

when I use the binary version(0.8.6i) from the vlc page I got following error:

Code: Select all

== Starting VLCExample == Creating a JVLC instance with args: 0) C:\11-eclipseWorkspace\test-videos\t-en.mpg [00000018] main interface error: no interface module matched "hotkeys,none" [00000018] main interface error: no suitable interface module [00000001] main private error: interface "hotkeys,none" initialization failed ... done.

Something is wrong with my self created binary can anyone provide a binary which is working or can anyone tell which is wrong with my compilation (I have used the instructions from this site http://wiki.videolan.org/Win32CompileCygwinNew).

cheers,

With the nightly build I got following error:

I have solved the problem with following thread: viewtopic.php?f=14&t=48627&p=155194&hil ... ll#p155194.

Now I have another problem: when I try to call jvlc.setVideoOutput() I got following error:

Hi mkeuschn!

It's good to know that I'm not the only one suffering from these problems. I encountered exactly the same errors and exceptions as you did and got stuck with the "java.lang.IllegalStateException: Component must be displayable" exception. Did you conquer this issue yet?

The code that gives me headache is:

Code: Select all

import java.awt.Canvas; import java.awt.Frame; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.awt.SWT_AWT; import org.videolan.jvlc.JVLC; import org.videolan.jvlc.MediaDescriptor; import org.videolan.jvlc.MediaPlayer; public class SWTVideoControl { private MediaPlayer mediaPlayer; public SWTVideoControl(Composite parent) { Frame awtFrame = SWT_AWT.new_Frame(parent); awtFrame.setVisible(true); awtFrame.setSize(150, 150); // just for testing addVLCcomponent(awtFrame); } public void startVideo() { mediaPlayer.play(); } private void addVLCcomponent(Frame awtFrame) { String[] args = new String[4]; args[0] = "-vvv"; args[1] = "--intf=dummy"; //arg[2] = "--ignore-config"; args[2] = "--no-plugins-cache"; args[3] = "--plugin-path=C:\\Program Files\\VideoLAN\\VLC\\plugins"; JVLC jvlc = new JVLC(args); Canvas awtCanvas = new Canvas(); awtCanvas.setSize(150, 150); // just for testing awtCanvas.setVisible(true); System.out.println(awtCanvas.isVisible()); // results in true jvlc.setVideoOutput(awtCanvas); awtFrame.add(awtCanvas); MediaDescriptor mediaDescriptor = new MediaDescriptor(jvlc, "C:/AMIDA/Video en Audio/Amida1.mpg"); mediaPlayer = mediaDescriptor.getMediaPlayer(); } }

The exception that is thrown reads:

Code: Select all

Exception in thread "main" java.lang.IllegalStateException: Component must be displayable at com.sun.jna.Native.getComponentID(Native.java:159) at org.videolan.jvlc.JVLC.setVideoOutput(JVLC.java:90) at org.amidaproject.ui.gui.SWTVideoControl.addVLCcomponent(SWTVideoControl.java:39) at org.amidaproject.ui.gui.SWTVideoControl.<init>(SWTVideoControl.java:20) at org.amidaproject.ui.gui.SimpleUI.show(SimpleUI.java:147) at org.amidaproject.ui.controller.MainController.showGUI(MainController.java:44) at org.amidaproject.ui.controller.MainController.main(MainController.java:84)

Can anyone tell me what the cause of this exception is? Exactly what component is "not displayable"?

[mkeuschn]

Sorry I am waiting for an explanation from anyone. A friend of me telled me to invalidate the container but I got the same error. Maybe you can try to invalidate the canvas. If that is working please reply.

the setVideoOutput Method have to be called after the gui is build.

hmm, nice, thanks a lot.

That's really usefull,is there anywhere the listener just to se if it runs out of the box?
