Problem with dealloc'ing and creating new instance of KxMovieViewController (threadsafe?)

Solution? I've used this commit 294812348bab7f33d400dd016e1948cdeadae52b

Seems I'm solved problem by adding in KxMovieDecoder.m

int lock_call_back(void ** mutex, enum AVLockOp op) {
    switch(op) {
        case AV_LOCK_CREATE:
            *mutex = (pthread_mutex_t *) malloc(sizeof(pthread_mutex_t));
            pthread_mutex_init((pthread_mutex_t *)(*mutex), NULL);
            break;
        case AV_LOCK_OBTAIN:
            pthread_mutex_lock((pthread_mutex_t *)(*mutex));
            break;
        case AV_LOCK_RELEASE:
            pthread_mutex_unlock((pthread_mutex_t *)(*mutex));
            break;
        case AV_LOCK_DESTROY:
            pthread_mutex_destroy((pthread_mutex_t *)(*mutex));
            free(*mutex);
            break;
    }

   return 0;
}

in + (id)initialize() av_lockmgr_register(&lock_call_back);

in - (void)dealloc() av_lockmgr_register(NULL);

It's okay solution?

BUT I have problem with EXC_BAD_ACCESS (_videoFrame->interlaced_frame in - (BOOL) setupVideoFrameFormat: (KxVideoFrameFormat) format)

AND The code above (int lock_call_back(void \ mutex, enum AVLockOp op)) not working with latest commit 36c3f080b1

Never saw such messages and have no idea about problem with locking.

How do you use KxMovieViewController?
