This will be fixed in the upcoming Qt 6.8 release, and is back-ported to 6.7.2. See https://bugreports.qt.io/browse/QTBUG-125006, which adds a check for the QT_FFMPEG_PROTOCOL_WHITELIST environment variable, which the user can set to override the whitelist with their own.

Try adding m_imageCapture.setCaptureDestination(QCameraImageCapture::CaptureToFile);.

P.S.

QCheckBox *cam = new QCheckBox(ci.description()); vailableCameras->setItemWidget(lwi, cam);

Hurts my feelings. See https://forum.qt.io/post/486329 it applies also to QListWidgetItem with the only difference that you don't, obviously, specify a column

IIRC, the two builds are not using the same backend.

Thank you, @Diracsbracket. From what you have commented I have achieved my audio playback of raw audio data.

Although the raw audio format is 32bits, and the supported formats indicated that 32 bits was supported, in actuality for my windows OS, i think only 8 bit Unsigned Int or 16 bit Signed Int work.

Hi,

Usually, to play sound effect, the QSoundEffect class is used. Wouldn't that fill your need ?

Hi,

Then that's something you should ask to the QtAV authors. It's not an official Qt module.

From a quick look at the sources of windeployqt, it seems that you can path qmldir several times so it will search in all the folders you path as parameter.

Hi there, I'm in the exact same boat as you. also

QMediaMetaData::Author

returns blank on Linux but works in Windows
Using Qt5.5.1... Been looking for a few days now for a solution with no luck too.

It might be a bit short, indeed. You are welcome to improve it and submit a patch to Qt :)

@tmason202 , try this one

void QTSemiTransparentWidget::paintEvent(QPaintEvent* event) { QPainter painter(this); painter.setOpacity(0.5); QStyleOption opt; opt.initFrom(this); QStyle* pStyle = QApplication::style(); pStyle->drawPrimitive(QStyle::PE_Widget, &opt, &painter, this); }

at least you should draw something in paint event not to just set an opacity.
