module "QtMultimedia" is not installed

tomy

I guess that example (I search for that on Docs) will work out the problem.

SGaist

If it does, then you know that your installation is fine.

You can then start from it to build your own application.

tomy

I didn't get your intention properly I guess. Do you mean that the project is written/defined well? (So why I get that error!?)

Or you mean that I can remedy that issue using that example on Docs?

SGaist

The second case.

tomy

I searched for a remedy fort the problem on the Docs, but as usual Docs are not helpful except for one who is quite experienced and just walks through it to be sure about something! :|

All I collected is that I need to add the following two lines in the project's CmakeLists.txt file:

find_package(Qt6 COMPONENTS Multimedia REQUIRED) target_link_libraries(qml_1 PUBLIC Qt::Multimedia)

But the project's CmakeLists.txt file already contains those two lines! Should I replace them with these two ones or merge them?

SGaist

Did you successfully build the example ?

tomy

Do you meant this example?

I didn't even find it on the Qt Creator examples section!

So how could I build it?

My 2 penneth :)

In examples, just type video into the search bar and look for QML Video Example.

But, before you bother with the above example, I see no mention of starting the Maintenance Tool and checking that QtMultimedia is actually included/installed in your current set up, might be worth a look.

I recently installed Qt6 and found I could not run any multimedia type apps with the same error you have, but checking maintenance tool, I could see it was not included originally, now it's installed and I have just built a basic test app to run an mp3, it works as expected.

I've already done this! :(

I see no mention of starting the Maintenance Tool and checking that QtMultimedia is actually included/installed in your current set up

I've already done this one as well! But there's no such an item called QtMultimedia to install! :(

What is the problem indeed, please? :(

SGaist

You can also clone the QtMultimedia module to get the example code.

@tomy - did you expand your version in the menu?, if you do, you should see "Additional Libraries" in the list, among the contents, you should find QtMultimedia.

In my image, you see I have expanded the version I have installed (Qt 6.2.3)........additional libraries/QtMultimedia.

How odd that you have no examples with your installation, I thought they were automatically included.

tomy

@Markkyboy

I installed that API and now I can run the project, but there're new errors!

Markkyboy

@tomy because they are not valid elements of MediaPlayer for Qt6, they are for Qt5.

Nearly all documentation is online for your perusal;

Because your code is wrong.

If you look at the code here,
https://doc.qt.io/qt-6/qml-qtmultimedia-videooutput.html

The video output is used for media player. Where is your player? How do you code your player?

property "source" does not exist in VideoOutput from
