在MSDN上找到个帖子：

SYNTAX ERROR : ( FFMPEG SOURCE CODE RUNNING ON VS2012)

在VS2012上编译ffmpeg遇到错误：

AVInputFormat ff_yop_demuxer = {
.name = "yop", // error on dot operater
.long_name = NULL_IF_CONFIG_SMALL("Psygnosis YOP"),
.priv_data_size = sizeof(YopDecContext),
.read_probe = yop_probe,
.read_header = yop_read_header,
.read_packet = yop_read_packet,
.read_close = yop_read_close,
.read_seek = yop_read_seek,
.extensions = "yop",
.flags = AVFMT_GENERIC_INDEX,
};

对结构体中的成员进行指定初始化，例如： .name = "yop", 在VS2010 、VS2012 上不支持，VS2013才支持

编译时报错，就是下图中红色的地方
