[vlc-devel] MAC Mozilla Plugin seg fault

[shahrooz]

Hello,
I am building a xul application on Mac, I tried to use to 1.0.3 source  
from git, but it has a problem, when closing the tabs in that uses vlc  
plugin overlay window was not cleared and made the application  
unusable(covering everything else), video frame was cleared after  
closing the application thou.
So, I tried to build the latest git, as it seems that people are  
working on opengl and macosx but using the new codes when closing a  
tab the application crashes with seg fault error.
Does anyone working on this? I have C/C++ background, but no opengl  
experience, how can I help making a stable mozilla plugin for Mac?
Appreciate your help, hope I can contribute in some way.


Peace
