#8 MP3 files won't open at MSWIN

[ezra]

Hey,

it's regarding http://sourceforge.net/projects/karlyriceditor/forums/forum/1048726/topic/3947976

It's not possible to open mp3 files at an German Vista and German XP OS. I checked the mp3 file with WinMP3Packer. Everything fine set to CBR. During opening KarLyrEditor I get a XINE error message. But there doesn't excist a XINE package for MSWIN. It seems to be Linux only. All error messages and the regarding mp3 file can be found at the KarLyrEditor folder at:

"... Download Windows binaries
Karaoke Lyric Editor provides the installer which bundles Qt libraries and the application. Download it here. Note: it depends on Windows Media Player to play audio files, so if your system cannot play MP3 files, neither would the editor..."

Yes, I confirm that the installed Windows Media Player can play mp3 files.

Here is the first step for a solution:

It was the same for me: all mp3 files (and other audio files) won't open on Windows (XP, German).
So I tried to compile the source code with Qt 4.7.2 and QtCreator (QTSDK 1.1 beta) And visual studio 2008.

There is a problem with the method PageMusicFile::phonon_StateChanged

After removing the checks for "isSeekable" and "totalTime" the mp3 files are handled well.

This event is called several times (on every state change)
- the first call is with isSeekable = false
- the second call is with isSeekable = true

So my conclusion:
only Phonon-ErrorStates should be detected in this method.
checks for "seekable" and "audio lenght" should be done somewhere else.

BWT:
the XINE Message is a Warning/Information not an Error Message.
For me it works well with GStream
