Hello,

I am playing mulitple udp streams within libvlc and what appears randomly i get access violations in libfreetype_plugin.dll (read of address 00000000) in both vlc 1.1.9 and vlc 1.1.6.

Any ideas?

I am using LibVLC too, and I have the same problem, but with local avi files.

Either the application starts ok, or it crashes in libfreetype_plugin.dll.

It feels like, if something in 1 of 2 threads takes somewhat longer than it usually does (and thus something is not completely initialized), the thing crashes.

Doesn't look like a valid call stack to me. But I've seen possibly similar crash reports on Ubuntu. You should probably try VLC 1.2.
