I want to get 3rd part softeware can decode music with no-ascll name such as chinese

chaochao

now， i am useing libzply. but when i open a music named by chinese ,libzplay will open err;

bool LuoMusic::musicDecode(const QString &filename)
{
  //  filename.toLocal8Bit()
  QByteArray ba  = filename.toUtf8();
  const char * name = ba.data();
   qDebug()<<name;

    ZPlay *player = CreateZPlay();
    if(player == 0)
      return false;

    int ver = player->GetVersion();
     // check if we have version 1.90 and above ( 1.90 if PF (pattent free) version, 2.00 version is full version
     if(ver < 190)
        {
            player->Release();
            return false;
        }
   //  qDebug()<<QString("libZPlay v.%1.%2i\r\n\r\n").arg(ver / 100).arg(ver % 100);

     if(player->OpenFile(name, sfAutodetect) == 0)
         {
             qDebug()<<QString("Error: %1 \nPress key to exit.\r\n").arg(player->GetError());
            // getch();
             player->Release();
             return false;
         }
}

thank for your help

Hi,

What exact error your getting ?

chaochao

@SGaist

if(player->OpenFile(name, sfAutodetect) == 0)
{
qDebug()<<QString("Error: %1 \nPress key to exit.\r\n").arg(player->GetError());
// getch();
player->Release();
return false;
}

like this：
Error: File open error. \nPress key to exit.\r\n

SGaist

What OS are you on ?

@SGaist windows 7

Are you sure your filename and paths are correct? Are your filenames written in UTF-8?

Call qDebug() << QDir::current().entryList(). Is your file in the list?

SGaist

Since you are passing the path to an external library you should call QDir::toNativeSperators use the result to pass the path to player->OpenFile

chaochao

@SGaist I did that ,but i got a same err. I think the problem is not this.Because when i pass the path like this C:\Users\Public\Music\Sample Music\Sleep Away.mp3 ,it will be ok.But when Sleep Away is replaced with chinese ,it will return err.

What encoding is your filename? UTF-8, or EUC-CN, or GB18030, or something else?

chaochao

@JKSH filename get by QFileDialog::getOpenFileNames and convert to const char * by under code

  QByteArray ba  = filename.toUtf8();
  const char * name = ba.data();

name will pass to OpenFile

SGaist

What @JKSH is asking is not what you are using to decode the filename but how it is encoded by your OS.

chaochao

@SGaist GBK2312

If your filename is not encoded in UTF-8, that means toUtf8() will give you the wrong path.

Try converting your filename to the GB2312, not UTF-8:

QTextCodec* codec = QTextCodec::codecForName("GB2312");
QByteArray ba = codec->fromUnicode(filename);
const char* name = ba.data();

chaochao

@JKSH as your code ,if i qDebug()<<name;

it will output
C:/Users/Public/Music/Sample Music/????.mp3

What do you see if you call qDebug() << ba?

Does zplay recognize this name?

What happens if you use Windows functions to get the filename? http://stackoverflow.com/questions/3176208/files-in-directory-in-c

Don't forget you still need to first convert the path to native separators before passing it to your other library.
