我运行了从站点http://h264bitstream.sourceforge.net/下载的h264解析器程序

当我运行代码时,出现以下错误



在下面的代码中

else if( pps->slice_group_map_type == 6 )
        {
            pps->pic_size_in_map_units_minus1 = bs_read_ue(b);
            for( i = 0; i <= pps->pic_size_in_map_units_minus1; i++ )
            {
                **pps->slice_group_id[ i ] = bs_read_u(b, ceil( log2( pps->num_slice_groups_minus1 + 1 ) ) ); // was u(v)**
            }
        }
    }


 if( pps->num_slice_groups_minus1 > 0 &&
        pps->slice_group_map_type >= 3 && pps->slice_group_map_type <= 5)
    {
        sh->slice_group_change_cycle =
            **bs_read_u(b, ceil( log2( pps->pic_size_in_map_units_minus1 +
                                     pps->slice_group_change_rate_minus1 + 1 ) ) ); // was u(v) // FIXME add 2?**
    }


bs_write_ue(b, pps->pic_size_in_map_units_minus1);
            for( i = 0; i <= pps->pic_size_in_map_units_minus1; i++ )
            {
                **bs_write_u(b, ceil( log2( pps->num_slice_groups_minus1 + 1 ) ), pps->slice_group_id[ i ] ); // was u(v)**
            }
        }

我该怎么办才能解决呢?

最佳答案

修改对log2的调用,如下所示:

log2( (double)(pps->num_slice_groups_minus1 + 1) )
