[id3lib-devel] It seems to me that it is very buggy

[Kenji C. <ken...@gm...>]

Hi, I've been using id3lib for a while, and having a few problems with it.

Problem 1:
For some mp3 inputs, the library crashes in tag_impl.cpp, line 50.  That's
because the String size;  is an empty string.

Problem 2:
For some mp3 inputs,  ID3_Tag::Link() would never return.

Problem 3:
For some mp3 inputs, changes don't save back to the file.


All those 3 types of mp3 files are all normal mp3 files and can be edited by
other program without any problem.

I found that problem #2 and #3 happen only if the file name is in Chinese.
And the char* version of ID3_Tag::Link( char* ) always returns error, so I'm
actually using ID3_Tag::Link(ID3_Reader &, ... )    to link my files.
And for the same mp3 file, the following code doesn't work or produces
problem #2 or #3:

ifstream s ( path , ifstream::in | ifstream::out );  // path contains the
chinese path
ID3_IFStreamReader r( s );
ID3_Tag tag;
                tag.Link( r , ID3TT_ID3);

But if I rename the file to let say    "abc.mp3", and the following will
work!!!

ID3_Tag tag;
                tag.Link( "abc.mp3" , ID3TT_ID3);

and with the same name "abc.mp3", the following will NOT work!!    <---
problem #2    only for some files

ifstream s ( "abc.mp3", ifstream::in | ifstream::out );
ID3_IFStreamReader r( s );
ID3_Tag tag;
                tag.Link( r , ID3TT_ID3);   // never return


I must get my program to work with non-english file names, and all this
happen only to some of my mp3 files, not all of them.
I notice this project has got much changed since 2003. I'm trying other
libraries that do the job for me,
but the one that is very close to what I want "libid3tag" is also buggy, and
it just can't write back to the file properly.

So please is there anyone who can help me?
