如歌手，歌名等

我想提取并修改这些信息，请问哪有相关资料？？
但是这样修改了的文件不能播放啊

找到了

RealMedia_File_Header{ UINT32 object_id; UINT32 size; UINT16

object_version; if (object_version == 0) { UINT32 file_version;

UINT32 num_headers; }}

Properties{ UINT32 object_id; UINT32 size; UINT16 object_version;

if (object_version == 0) { UINT32 max_bit_rate; UINT32

avg_bit_rate; UINT32 max_packet_size; UINT32 avg_packet_size;

UINT32 num_packets; UINT32 duration; UINT32 preroll; UINT32

index_offset; UINT32 data_offset; UINT16 num_streams; UINT16

flags; }}

Media_Properties{ UINT32 object_id; UINT32 size; UINT16
