Problem with QML Video in Android



  • Hi!
    I'm developing an app for android and faced with very strange problem.
    This is my simple QML code:

    import QtQuick 2.7
    import QtQuick.Controls 2.0
    import QtQuick.Layouts 1.0
    import QtMultimedia 5.7

    ApplicationWindow {
    visible: true
    width: 640
    height: 480

    property int counter
    
    property string fileName: "file:///sdcard/Android/data/resources/004.mp4"
    

    // property string fileName: "file:E:/Programm/CRM/Crm2/resources/004.mp4"

    Video {
    id: video
    anchors.fill: parent
    volume: 0

    property bool allowed: true
    
    onPlaying: {
        console.log("Playback started");
    }
    
    onStatusChanged: {
        console.log("StatusChanged", video.status, video.source);
    
        if (video.status ===  MediaPlayer.EndOfMedia )
        {
            console.log("++++++++++++++++++LOOP N ++++++++++++ ", counter);
            counter++;
        }
    }
    
    onErrorChanged: {
        console.log("Error....", video.errorString);
    }
    
    onPaused: {
        console.log("pause")
    }
    
    onStopped: {
        console.log("Stopped... Click to play again...")
    }
    
    onSourceChanged: {
        console.log("source changed", video.source)
    }
    onStateChanged: {
         console.log("STATE  changed", video.playbackState)
    }
    

    }
    MouseArea {
    anchors.fill: parent
    onClicked: {
    if (video.playbackState === MediaPlayer.StoppedState ){
    console.log("CLICK TO PLAY AGAIN...")
    video.playlist = pl;
    video.play();
    }

    }
    

    }

    Playlist {
    id: pl
    playbackMode: Playlist.Loop

    Component.onCompleted: {
        addItem(fileName);
    }
    

    }
    }
    This code works fine in Windows. It working some days long...
    But not Android.
    In Android 4.2.2 it works 250 sycles of repeat. 512 MB memory
    In Android 4.4.2 it works about 600 sycles of repeat. 1 GB memory
    And at the same device the limit of repeats is exectly the same.

    The error is:
    E/EGL-ERROR: mali_image* _egl_android_map_native_buffer_yuv(android_native_buffer_t*):329: Unable to set data for YUV image (format: 12530)
    E/GLConsumer(16280): [unnamed-16280-563] error creating EGLImage: 0x3003
    W/GLConsumer(16280): [unnamed-16280-563] updateAndRelease: unable to createImage on display=0x1 slot=4

    W/JNIHelp (16280): Discarding pending exception (java.lang.RuntimeException: Error during updateTexImage (see logcat for details)) to throw java/lang/IllegalStateException
