Replay video makes animation lag

[sinadogru]

Hey,

on the same screen while playing video and have another elemnt which plays animation get lags when the video replay.

here is a sample code to reproduce;

import QtQuick 2.2
import QtQml 2.0
import QtQuick.Window 2.1
import QtMultimedia 5.0

Rectangle {
width: 1920
height: 1080
id: root
objectName: "root"
visible: true
color: "black"
property int level: 0

Video {
    anchors.fill: parent
    id: myVideo

    visible: true

    source: "file:///home/pi/Videos/SampleVideo_1080x720_2mb.mp4"
    autoPlay: true

    fillMode: VideoOutput.Stretch

    onStopped: {
        console.log("Stopped.");
        myVideo.seek(0);
        myVideo.play();
    }

    onStatusChanged: {
        console.log("Status changed to: " + status + ".");
    }
}
Rectangle {
    border.width: 2
    border.color: "black"
    color: "lightsteelblue"
    anchors.horizontalCenter: parent.horizontalCenter
    width: 250
    height: text.height + 10
    y:1000
    NotificationBox {
        id:text
        width: 200
        anchors.verticalCenter: parent.verticalCenter
        anchors.horizontalCenter: parent.horizontalCenter
        text: "start ------ abcdefghijklmnopqrtaksdjfkdfjklsdjflksdjfklsjadfkljsad;flasjdlfjasdfjldsdfljf---- end"
    }
}

}

And here is the NotificationBox;

import QtQuick 2.0

Item {
id:marqueeText
height: scrollingText.height
clip: true
property int tempX: -width
property alias text: scrollingText.text
Text {
x: tempX
id:scrollingText
Behavior on x {
NumberAnimation { duration: 200 }
}
}

// MouseArea {
// id:mouseArea
// anchors.fill: parent
// onClicked: {
// tempX = 0;
// timer.running = true;
// }
// }

Timer {
    id:timer
    interval: 200; running: true; repeat: true
    onTriggered:{
        tempX = tempX + 5
        scrollingText.x = -tempX;

        if( tempX + marqueeText.width > scrollingText.width + parent.width) {
            timer.running = false
            pauseTimer.running = true
        }
    }
}

Timer {
    id:pauseTimer
    interval: 500; running: false; repeat: false
    onTriggered: {

// scrollingText.x = 0
tempX = -parent.width
timer.running = true
}
}
}

You can check this bug with a shorter video easily.

Thank You,
Sina

What version are you referring to?

[keytee]

Hello. Same here. Also when changing source. Is there any way to do .source change of a video in async mode? (lattest version, just cloned from the git.)

[carlonluca]

It is async in the binaries. Since 5.0.0 it was improved.

[carlonluca]

So you mean the animation interrupts while opening a new media? In that case it is normal as setting the media results in POT reading it, parsing the container, creating players etc...
Some improvements can be found in >= 5.0.0 as this is no more done in the renderer thread. Still I expect not a perfect animation on Pi1, which is single core. Maybe better on Pi2.

[carlonluca]

Probably a dup of #28.

[sinadogru]

Hello,

I was out out of for shopping. For example, when I am looping a video, every time when it start over (seek(0)) screen got a bit of lag, for example if I have an animated scrolling text like on billboards, it gets lag.

Yes I've just viewed issue #28 and it looks like duplicate actually. I was using V4.5.1 and forgot to write it to title. I am sorry.

I am just a bit tired so I will check this V5.0.0-beta on later . Btw I am using POT on Pi2.

[carlonluca]

In this case yes, testa 5.0.0 beta2.

[sinadogru]

Alright, I will check it and I will give feedback.

Thank you.

[carlonluca]

Reopen if needed.

[sinadogru]

Yes beta 2 fixed it. Thank you.
