OSX 10.13.5

IOS 11

QT 5.11.1

I am loading a base64 encoded mp3 into a QBuffer. Then attempt to play it using a QMediaPlayer object. This sample code plays fine on Windows10 but does not output any song.

The code works if I replace the QBuffer by a QFile with the extension .mp3

It seems that playing a sound from a QBuffer is not implemented on OSX, Android and IOS. This breaks the expectation that a QT code should be running on any platform.

buffer.open(QIODevice::ReadWrite); buffer.write(QByteArray::fromBase64(QJsonDocument::fromJson(reply->readAll()) .object()["audioContent"].toString().toUtf8()));

buffer.seek(0);

player.setMedia(QMediaContent(),&buffer);

player.play();
