[vlc-devel] Fwd: Pb with JVLC on MacOSX Leopard

[Eric Nicolas]

Ok, I switched to JDK 1.5 for now. This JDK is 32-bits, so there is no  
arhitecture compatibility problem anymore.

However, the test program org.videolan.jvlc.interlan.LibVlcImpl.main()  
crashes.
The crash report says :

	Thread 21 Crashed:
	0   com.apple.QD                  	0x90d21609 GetPixBounds + 8

	7   libSystem.B.dylib             	0x91eb7f52 thread_start + 34

The output console says :

	Starting vlc
	version: 1.0.0-pre2 Goldeneye
	changeset: exported
	compiler: gcc version 4.2.1 (Based on Apple Inc. build 5555) (LLVM  
build 2056)
	Drawable=485830896
	*** LibVLC Exception not handled: No active input
	Set a breakpoint in 'libvlc_exception_not_handled' to debug.
	Playing started.
	frame skip 8
	frame skip 8

Any idea, anyone ??

Thanks, EN.
