I already posted this issue in the developer's mail list and sent a mail to
littejohn but I got no answer :(
I have developed a very simple videoconfence project using JVLC (stable
vlc-0.8.6c version) and a few weeks ago I decided to upgrade the JVLC version
to the newer one (subversion vlc-0.9.0 version). Unfortunately I found that the
version I downloaded didn't work... and, what it is worse, the problem persist.
I explain the error:
1) When you run VLCExample you get:
[code]fictorine at Mario:~/vlc-trunk3/bindings/java$ java VLCExample
== Starting VLCExample ==
Creating a JVLC instance without args main libvlc debug: VLC media
player - version 0.9.0-svn Grishenko - (c) 1996-2007 the VideoLAN team
 main libvlc debug: libvlc was configured with ./configure
'--enable-java-bindings' '--enable-wxwidgets' '--enable-v4l' '--enable-v4l2'
 main libvlc: Running vlc with the default interface. Use 'cvlc' to
use vlc without interface.
 main libvlc debug: translation test: code is "C"
Exception in thread "main" org.videolan.jvlc.VLCException: not implemented
at org.videolan.jvlc.Audio._install_callback(Native Method)
2) That's because, in callback-jni.cc, the code is:
[code]JNIEXPORT void JNICALL Java_org_videolan_jvlc_Audio__1install_1callback(
*env, jobject _this )
if (jvm == NULL)
env->GetJavaVM( &jvm );
audioClass = env->GetObjectClass( _this );
wakeupListenersMethod = env->GetStaticMethodID(audioClass,
libvlc_exception_raise( &exception, "not implemented" );
It seems the JVLC class is under construction...
The questions are:
Do JVLC programmers know this bug? Are they working on it? When will it be
fixed? Can I help in any way?
EDIT: I'm using Ubuntu Gutsy Gibbon if this helps :wink:
