Qt Code:

Switch view

QString vidpath = QApplication::applicationDirPath();
    vidpath = "/home/development/videos/";
    QString filepath = QApplication::applicationFilePath();
    filepath = "*.avi";
    ui->videoPlayer->load(Phonon::MediaSource(vidpath + filepath));

QString vidpath = QApplication::applicationDirPath();
    vidpath = "/home/development/videos/";
    QString filepath = QApplication::applicationFilePath();
    filepath = "*.avi";
    ui->videoPlayer->load(Phonon::MediaSource(vidpath + filepath));

To copy to clipboard, switch view to plain text mode

I get this error

To copy to clipboard, switch view to plain text mode

but if i change the above code to this it works

Qt Code:

Switch view

QString vidpath = QApplication::applicationDirPath();
    vidpath = "/home/development/videos/";
    QString filepath = QApplication::applicationFilePath();
    filepath = "myvid.avi";  //changed to just 1 file from that folder
    ui->videoPlayer->load(Phonon::MediaSource(vidpath + filepath));

QString vidpath = QApplication::applicationDirPath();
    vidpath = "/home/development/videos/";
    QString filepath = QApplication::applicationFilePath();
    filepath = "myvid.avi";  //changed to just 1 file from that folder
    ui->videoPlayer->load(Phonon::MediaSource(vidpath + filepath));

To copy to clipboard, switch view to plain text mode

yes i have searched google for about 3 days with different scenarios and still have had no success

i am new to qt and been working with it everyday all day for about 3 months trying to learn and troubleshoot problems this is one problem a cant seem to fix on my own

what im trying to accomplish here is playing all files in the folder vidpath with any file that ends with .avi if there is a better solution please point me in that direction hope this is not a total newbie question i been beating my head off the wall for days now trying to get this to work

thanks

To play multiple media file in a sequence , you need to create Phonon::MediaObject
like this
/*********/
Phonon::MediaObject *metaInformationResolver;
QStringList files = QFileDialog::getOpenFileNames(this, tr("Select Music Files"),
QDesktopServices::storageLocation(QDesktopServices ::MusicLocation));

if (files.isEmpty())
return;

int index = sources.size();
foreach (QString string, files) {
Phonon::MediaSource source(string);

sources.append(source);
}
if (!sources.isEmpty())
metaInformationResolver->setCurrentSource(sources.at(index));
