[SOLVED] QFSFileEngine::open: No file name specified

[A Former User]

Hello, I am trying to save Playlist, but keep getting error "QFSFileEngine::open: No file name specified"

@void MainWindow::on_pushButton_6_clicked()
{
playlist->save(QUrl("C:/Users/Admin/Desktop/Test"));
}@

also tried:
@playlist->save(QUrl("C:/Users/Admin/Desktop/Test/test.txt"));@

I am trying to find to which formats QMediaList can be saved, but without success...

@bool QMediaPlaylist::save(const QUrl & location, const char * format = 0)@
Can someone give me an example of how to correctly use that format???

Hi,

You didn't set the protocol when creating your QUrl object.

You should rather use "fromLocalFile":http://qt-project.org/doc/qt-5/qurl.html#fromLocalFile

Hope it helps

Error has gone, but it still does not save playlist...

@playlist->save(QUrl::fromLocalFile("C:/Users/Admin/Desktop/Test/test.m3u";);@

Did you check whether save returns true or false ? And what error you can retrieve ?

[A Former User]

Hey, how can I check that??? I don't get any error...

[SGaist]

QPlayList::save() returns a boolean value to tell you if it succeeded or not

QMediaPlayList::errorString() returns a string corresponding to the current error.

Did you use both ?

@"Playlist format is not supported." @

I read documentation and nowhere says what format is supported...

@ playlist->save(QUrl::fromLocalFile("C:/Users/Admin/Desktop/Test/test.m3u"),);@

Tried with all of them and none is working... Unless I am doing something wrong... It does create file test.m3u but then prints error "Playlist format is not supported"...
Multimedia playlist .m3u
Multimedia playlist with Unicode support .m3u8
Windows Media Player .wpl

What happens if you use:

@ playlist->save(QUrl::fromLocalFile("C:/Users/Admin/Desktop/Test/test.m3u"), "m3u");@ ?

aww... It works :) ... I tried with "*.m3u", ".m3u" but never just "m3u"... Thanks

Another question, when I am loading playlist, how can I display file names in qlistwidget???

[SGaist]

You can use a for loop and get each QMediaContent from the playlist. With that you should be able to get the file path and then the name

Awww works :) Thank you...

@void MainWindow::on_pushButton_7_clicked()
{
playlist->load(QUrl::fromLocalFile("C:/Users/Admin/Desktop/Test/playlist.m3u"), "m3u");
int count = playlist->mediaCount();
for(int i = 0; i < count; i++){
QString test = playlist->media(i).canonicalUrl().fileName();
qDebug() << test;}
}@
