qml 用Video控件在rk3126c上播放在线视频，网络很差的情况下，调用系统自带stop函数，会导致UI卡死
1、
Video {
id: player
anchors.fill: parent
// orientation: 90
// fillMode: VideoOutput.Stretch
fillMode: VideoOutput.PreserveAspectFit
property bool isPlaying: false
onBufferProgressChanged: {
console.log("______onBufferProgressChanged______", bufferProgress)
}
onPositionChanged: {
progressBar.value = position / duration
console.log("_____onPositionChanged_____", progressBar.value, position, duration)
}
}

调用pause暂停函数后，onPositionChanged一直反复打印，但是position一直不变，点击按钮将播放器停止，直接卡死

Ui_ArcDisplayBtn {
id: nextStepBtn
anchors.right: parent.right
anchors.rightMargin: 22
anchors.bottom: parent.bottom
anchors.bottomMargin: 19
m_text: qsTr("开始")
MouseArea {
anchors.fill: parent
onClicked: {
console.log("_______11_____")
player.stop()
console.log("_______22_____")
// 播放语音
if (isVoiceOpen) {
uiproc_data_interaction.playAudio(voiceObj.voice3)
}
console.log("_______33_____")
stackView.push(cookStepCom, StackView.Immediate)
console.log("_______44_____")
}
}
