Cannot save playlist

[bclay1297]

I am using Qt 5.12 and Visual Studio 2017 to create an audio application. I used a method shown below (CreatePlayList) to create a QMediaPlaylist. I can use the playlist to play and seek without problems. I trying to use the built in save method by calling
QString location = "M/Tools/Language/AudioServer/NewTest.txt";
bool saved = mPlaylist- >save(QUrl::fromLocalFile(location));

saved is always false and no file is created.

Any thoughts or suggestions would be greatly appreciate.

		bool added = mPlaylist->addMedia(QUrl::fromLocalFile(filename));

		mMediaPlayList.push_back(filename);

		mPlaylist->setCurrentIndex(1);

		status = -1;
	}
}

return(status);

Hi,

Are you sure the path is valid ?

[bclay1297]

Yes. I have tried both absolute paths and relative paths neither worked. I could not tell from the documentation if the location is supposed to be a file name or directory name

@bclay1297 said in Cannot save playlist:

NewTest.txt

I don't think that .txt is a valid playlist format extension.

I also tried m3u. Someone posted a comment on another site that said the playlist format was based on a plugin but there was no indication of where or what the plugin might be. I am beginning to think it is another one of those functions not implemented in the Windows version of Qt just like the QMediaRecorder.

m3u is available on all platforms.

Look into the plugins folder.

Thank you for your help I was looking in the wrong place for the plugin. It is working now
