{
    AVFilter av_unused(**filter) = NULL;

    printf("Filters:\n");

    /* could not find filter corresponding to prev */
    if (prev && !(*filter_ptr))
        return NULL;

    /* find next filter with specific options */
    while (*(filter_ptr = av_filter_next(filter_ptr)))
        if ((*filter_ptr)->priv_class)
