Qt Multimedia for iOS. How?

bogong

Hello!
I am trying to play video from URL. Using QML MediaPlayer, all is working for Android, MacOS, but failing with iOS. How to use it in iOS? Is there any manuals? Or examples, key point FOR IOS?

Have you followed the documentation about iOS limitations? https://doc.qt.io/qt-5/qtmultimedia-ios.html Seems unrelated but maybe will help...

@sierdzio Thx for reply. I've seen it. Looks for me unrelated. I am using this code:

Video {
	id: video
	width : parent.width
	height : parent.height
	source: "url here "

	MouseArea {
		anchors.fill: parent
		onClicked: {
			video.play()
		}
	}

	focus: true
	Keys.onSpacePressed: video.playbackState == MediaPlayer.PlayingState ? video.pause() : video.play()
	Keys.onLeftPressed: video.seek(video.position - 5000)
	Keys.onRightPressed: video.seek(video.position + 5000)
}

It's working perfectly on Android and MacOS but on iOS just hear the sound. But no any video. This example from doc https://doc.qt.io/qt-5/qml-qtmultimedia-video.html And sound playing just few seconds at begin.

@sierdzio It's kind of bug and I don't know where. When I am running application on simulator from Qt Creator or XCode - It's not working with this kind of error:

dyld: warning, Ignoring DYLD_IMAGE_SUFFIX because DYLD_ROOT_PATH is used.
QML debugging is enabled. Only use this in a safe environment.

When I run it on Device from XCode or QtCreator it's working. I mean about QMultimedia. I am running it via this code:
In *.pro

QT += multimedia

In *.qml

Video {
	id: video
	width : parent.width
	height : parent.height
	source: "URL Here"
	MouseArea {
		anchors.fill: parent
		onClicked: {
			video.play()
		}
	}

	focus: true
	Keys.onSpacePressed: video.playbackState == MediaPlayer.PlayingState ? video.pause() : video.play()
	Keys.onLeftPressed: video.seek(video.position - 5000)
	Keys.onRightPressed: video.seek(video.position + 5000)
}

For me issue closed with QMultimedia. If anyone knows why it's happening - write a message here.
