关于C99中的新特性：指定初始化 Designated initializers

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
