Video playback gets stuck on a first second (QtMultimedia 5.12)

danilabagroff

Hello!

My goal was to play video from youtube using VideoOutput, but video playback gets stuck(audio is ok) on first(differs time to time, but at the beginning) second, now I'm simplifying everything and trying to play some random mp4 from https://www.radiantmediaplayer.com/media/bbb-360p.mp4 — same result.

What should I try to check or libVLC is just one solution? any thoughts would be appreciated ;)

I'm on macOS 10.14.5, QtCreator 4.9.1 with Qt 5.12.4
Deployment target is iOS simulator.

The code is "easy-peasy-qmlesey":

MediaPlayer {
	id: mediaPlayer
	autoLoad: false
	autoPlay: true

	onPlaybackRateChanged: {
		console.debug("playbackRate: " + playbackRate);
	}

	onPlaybackStateChanged: {
		console.debug("playbackState = " + mediaPlayer.playbackState);
		videoOutput.isPlaying = (playbackState === MediaPlayer.PlayingState);
	}

	onAvailabilityChanged: {
		console.debug("availability = " + mediaPlayer.availability);
	}

	onErrorChanged: {
		console.debug("error = " + mediaPlayer.error);
	}

	onStatusChanged: {
		console.debug("status = " + mediaPlayer.status);
	}
}

VideoOutput {
	id: videoOutput

	source: mediaPlayer
	anchors.fill: parent
	fillMode: VideoOutput.PreserveAspectFit

	property alias mediaSource: mediaPlayer.source
	property alias mediaPlayer: mediaPlayer
	property bool isPlaying: false
}

On the real device(iPhone5s) everything works as expected.
