why my evc build is with problem of vout?

[thaiqi]

Hello, I am building vlc-0.8.4 for an XScale 270 running wince.net v4.20. I first try the GNU compiler, for an mpeg2 ts file, the vlc runs happily. But when I try evc4.0(with sp4), it seems meeting problem with vout_Request(), I deliberately used Wingdi plugin, it calls thread creation and wait for signal, then I saw the thread signals but the wait doesn't return. Can someone give some light on this point for me? Thanks.

I ever doubt the thread signals earlier than the other thread begin to wait but now seems it is not such.
Need I build in some other modules that the evc project inside the \evc directory doesn't include?
