Issue with QMediaMetaData and media format

[pamputt]

Describe the bug I have install Qt 6.4.2 using aqt and I have the same issue that the one described in QTBUG-110883.

It seems that some media format (at least FLAC) are not supported by Qt when installed with aqt.

To reproduce

1. Install aqt using aqt install-qt linux desktop 6.4.3 -m all
2. Download https://bugreports.qt.io/secure/attachment/136780/QMediaMetaData_flac.zip
3. Unzip QMediaMetaData_flac.zip
4. cd QMediaMetaData_flac
5. mkdir build
6. cd build
7. cmake ..
8. make -j4
9. ./QMediaMetaData_flac

It prints

QMediaMetaData::Url QVariant(QUrl, QUrl("qrc:/test.flac")) QMediaMetaData::Duration QVariant(qlonglong, 0) QMediaMetaData::FileFormat QVariant(QMediaFormat::FileFormat, QMediaFormat::UnspecifiedFormat)

Expected behavior

It should prints some usefull information related to test.flac

Desktop (please complete the following information):

• OS: Ubuntu 22.04 LTS 64-bits
• aqtinstall(aqt) v3.1.3 on Python 3.10.6 [CPython GCC 11.3.0]

I have added some information. I think it is enough to reproduce

The response to the issue you linked suggested running lddtree against libQt6Multimedia.so.6. Can you show us the output of that command please? You should be able to find this file at INSTALL_DIR/QT_VERSION/gcc_64/lib/libQt6Multimedia.so.6.

I attempted to build your QMediaMetaData_flac project, on a fresh VM of Ubuntu 22.04, and I can reproduce the problem with Qt installed via aqtinstall. I also tried to build the project using Qt installed with the official GUI Qt installer, and that causes the problem as well.

I don't know what is causing this, but I am certain that this issue has nothing to do with aqtinstall because Qt 6.4.3 installed with the official installer has the same issue.

FYI, I tried lddtree libQt6Multimedia.so.6, and it doesn't show any broken links. If I were you, I'd go back to the Qt bug tracker and tell them to try using their own installer on Ubuntu 22 instead of Arch; that should reproduce the problem.

I have installed Qt 6.5.0 with aqt and the problem disappeared. Yet, it is still present for older Qt version (6.4.*). This problem has been reported upstream.
