Hello – QML newbie here. I am attempting to to create a trivial app for playback of video files. The code I have works fine for .wmv files, but when I try to playback an .mp4 file, nothing plays. Screen stays black.
I am using Qt 5.2 running on Windows 7. I can playback the .mp4 files with no problem in Windows Media Viewer, so I believe I have the right codecs installed. Qt does not report any errors and the video component reports that it is playing when I query it’s status. My code as follows. Any ideas what I need to do?
import QtQuick 2.2
import QtMultimedia 5.0
import QtQuick.Controls 1.1
import QtQuick.Dialogs 1.1
Rectangle {
width: 800
height: 600
color: "black"
FileDialog {
id: fbrowser
title: "Please select a video file"
}
Row {
id: buttonRow
Button {
id: goButton
text: "Start"
onClicked: {
videoPlayer.source = videoFileName.text;
videoPlayer.play();
}
}
Button {
id: stopButton
text: "Stop"
onClicked: {videoPlayer.stop(); }
}
Button {
id: chooseFileButton
text: "Select Video File..."
onClicked: {fbrowser.open();}
}
TextField {
id: videoFileName
width: 450
text: fbrowser.fileUrl
}
}
Rectangle {
id: videoRect
anchors {left: parent.left; top: buttonRow.bottom; topMargin: 5; right: parent.right; bottom: parent.bottom}
color: "transparent"
Video {
id: videoPlayer
focus: true
anchors.fill: parent
}
}
}
