你好, 大神我把glsl filter想要用在安卓, 首先我试过在windows且确认好用，但是我不能用在安卓的。那么把glsl filter我能不能用在安卓呢？我的环境是QT5,7和安卓6.0, 我的代码是如下,

import QtQuick 2.7 import QtQuick.Window 2.2 import QtQuick.Dialogs 1.2 import QtAV 1.7

Window { visible: true width: 640 height: 480 title: qsTr("Hello World")

Rectangle {
    anchors.fill: parent
    color: "black"

    VideoFilter {
        id: negate
        type: VideoFilter.GLSLFilter
        shader: Shader {
            postProcess: "gl_FragColor.rgb = vec3(1.0-gl_FragColor.r, 1.0-gl_FragColor.g, 1.0-gl_FragColor.b);"
        }
    }

    VideoFilter {
        id: grayscale
        type: VideoFilter.GLSLFilter
        shader: Shader {
            postProcess: "gl_FragColor.rgb = vec3(gl_FragColor.r * 0.3 +  gl_FragColor.g * 0.59 + gl_FragColor.b * 0.11, gl_FragColor.r * 0.3 +  gl_FragColor.g * 0.59 + gl_FragColor.b * 0.11, gl_FragColor.r * 0.3 +  gl_FragColor.g * 0.59 + gl_FragColor.b * 0.11);"
        }
    }

    VideoFilter {
        id: hflip
        type: VideoFilter.GLSLFilter
        shader: Shader {
            sample: "vec4 sample2d(sampler2D tex, vec2 pos, int p) {return texture(tex, vec2(1.0-pos.x, pos.y));}"
        }
    }

    VideoOutput2 {
        id: videoOutput
        anchors.fill: parent
        source: video
        opengl: true
        filters: [grayscale, hflip]
    }

    MediaPlayer {
        id: video
        autoPlay: true
    }

   MouseArea {
       anchors.fill: parent
       onClicked: {
           fileDialog.open();
       }
   }
    FileDialog {
        id: fileDialog
        onAccepted: video.source = fileUrl
    }
}

}

这个代码是在windows行好，但是在安卓不行的。我拜托，您帮忙我吧。谢谢。
