[英]Mp3 file is null using taglib(c++)
I am using taglib in c++ to change metadata from mp3 files. 我在c ++中使用taglib更改mp3文件中的元数据。 I have written a code that works great.
我写了一个很棒的代码。 But I found a MP3 file that cannot open with taglib.
但我发现无法使用taglib打开MP3文件。
The MP3 file has tags. MP3文件具有标签。 I can see them with Vlc media player and MediaInfo and with explorer.exe.
我可以通过Vlc媒体播放器,MediaInfo和explorer.exe看到它们。
I try this minimum codes but it say that the file is not valid. 我尝试使用此最小代码,但它表示文件无效。
TagLib::FileRef filer("file.mp3");
if(filer.isNull())
cout <<"null";
or this code: 或此代码:
TagLib::MPEG::File fileMpeg("file.mp3");
if(!fileMpeg.isValid())
{
cout << "file not valid";
}
other files work but not that one. 其他文件工作,但不是那个。 Thanks for your help.
谢谢你的帮助。
I found the problem, The problem was not from the files but, from the files name or directory. 我发现了问题,这个问题不是来自文件,而是文件名或目录。 To fix the problem I sand
cont wchar_t*
rather than const char*
because the files that I tried to open contain french characters from ISO or unicode encoding but not from ASCII. 要解决此问题,我将使用
cont wchar_t*
而不是const char*
因为我尝试打开的文件包含来自ISO或unicode编码的法语字符,但不包含来自ASCII的法语字符。
