[vlc-devel] Changes to libvlc_new? libvlc_run_interface?

[jboileau]

Thanks for the reply Pierre.

If I understand correctly: there is no real changes in how I should
use libvlc. If I encounter problems it may simply be that the libvlc
code is not in perfect working order presently because of the
sanitization. At least that clarifies things.

I guess I wasn't very clear. What I meant to point out is that the
behaviour seems to be different when I build my application in debug
mode than release mode. Since I remember from a while back that vlc
add an option for fast mutex under Windows, I wonder if that might
have anything to to with it. If I step in debug it hangs. Otherwise it
runs but does not perform as expected.

I don't have a backtrace of sorts because I don't get a crash. But
here are some traces I was able to produce if this helps. This trace
happened when I was able to call play but the play failed.  These
traces includes some of mine and some of VLC. It seems
