Update of /cvsroot/datatype/mp3/fileformat
In directory cvs01.internal.helixcommunity.org:/tmp/cvs-serv12137

Modified Files:
      Tag: hxclient_3_6_3_atlas
	mp3ff.cpp 
Log Message:
Fix Bug #10679: The bug happens when there are a lot of junk information in file \
header, so that the player can not find the sync word in a block of buffered data, \
then it causes a INVALID_FILE error. I modified the CRnMp3Fmt::InitStream_n function \
to ignore all unknown data until found a valid frame. I think it would not bring \
other problems except to waste a few time on type checking.
