Qt Multimedia for iOS. How?



  • Hello!
    I am trying to play video from URL. Using QML MediaPlayer, all is working for Android, MacOS, but failing with iOS. How to use it in iOS? Is there any manuals? Or examples, key point FOR IOS?


  • Moderators

    Have you followed the documentation about iOS limitations? https://doc.qt.io/qt-5/qtmultimedia-ios.html Seems unrelated but maybe will help...



  • @sierdzio Thx for reply. I've seen it. Looks for me unrelated. I am using this code:

    Video {
    	id: video
    	width : parent.width
    	height : parent.height
    	source: "url here "
    
    	MouseArea {
    		anchors.fill: parent
    		onClicked: {
    			video.play()
    		}
    	}
    
    	focus: true
    	Keys.onSpacePressed: video.playbackState == MediaPlayer.PlayingState ? video.pause() : video.play()
    	Keys.onLeftPressed: video.seek(video.position - 5000)
    	Keys.onRightPressed: video.seek(video.position + 5000)
    }
    

    It's working perfectly on Android and MacOS but on iOS just hear the sound. But no any video. This example from doc https://doc.qt.io/qt-5/qml-qtmultimedia-video.html And sound playing just few seconds at begin.



  • For now I found this https://github.com/wang-bin/QtAV Will try to build it for iOS



  • @sierdzio It's kind of bug and I don't know where. When I am running application on simulator from Qt Creator or XCode - It's not working with this kind of error:

    dyld: warning, Ignoring DYLD_IMAGE_SUFFIX because DYLD_ROOT_PATH is used.
    QML debugging is enabled. Only use this in a safe environment.

    When I run it on Device from XCode or QtCreator it's working. I mean about QMultimedia. I am running it via this code:
    In *.pro

    QT += multimedia
    

    In *.qml

    Video {
    	id: video
    	width : parent.width
    	height : parent.height
    	source: "URL Here"
    	MouseArea {
    		anchors.fill: parent
    		onClicked: {
    			video.play()
    		}
    	}
    
    	focus: true
    	Keys.onSpacePressed: video.playbackState == MediaPlayer.PlayingState ? video.pause() : video.play()
    	Keys.onLeftPressed: video.seek(video.position - 5000)
    	Keys.onRightPressed: video.seek(video.position + 5000)
    }
    

    For me issue closed with QMultimedia. If anyone knows why it's happening - write a message here.
