Video stops after seek()

[Melle_87]

Hi all,
If I use seek() to change the position of a video, the video position is changed, but the video is not playing.
Does anyone know this problem and has a solution?

Kind regards,

Hi,

Which version of Qt are you using ?
On which platform ?
Did you try to call play after seeking ?
Are you seeking while the media is playing ?
How are you triggering the seek ?

[Melle_87]

@SGaist:

• Qt 5.12.4
• Raspberry pi + Raspbian buster
• Yes, I call play() after seek(). (But it should not be necessary I think ...)
• Yes, I am seeking while media is playing.
• Seek is triggered through slider onMoved.

After calling seek() I can see that video position has changed. But the video is not running. Video position does not increment.

Does it happen with a specific file or all videos in general ?

[Melle_87]

@SGaist: It happens with all videos. I tried mp4 and avi.

[SGaist]

Can you show the code related to that ?

[Melle_87]

@SGaist: Yes, of course.

...
VideoOutput {
	anchors.top: middleVideo.top
	anchors.left: middleVideo.left
	anchors.right: middleVideo.right
	anchors.bottom: playPauseButton.top
	anchors.margins: 15
	source: media
	onVisibleChanged: {
		if (visible) {
			media.play()
		}
		else {
			media.stop()
		}
	}
}
MediaPlayer {
	id: media
	autoLoad: true
	autoPlay: true
	onStatusChanged: {
		if (status == MediaPlayer.EndOfMedia) {
			internShow = def_SHOW_LISTS
			media.source = ""
		}
	}
}
...
Slider {
	id: slider
	anchors.left: playPauseButton.right
	anchors.leftMargin: 50
	anchors.right: duration.left
	anchors.rightMargin: 50
	anchors.bottom: parent.bottom
	anchors.bottomMargin: 0
	height:30
	from: 0
	to: media.duration
	value: media.position
	stepSize: 1
	onMoved: {                    
		media.seek((parseInt(value/1000))*1000)
	}
}
...

@SGaist: I posted my code some days ago. Do you have any ideas?

[SGaist]

@Melle_87 said in Video stops after seek():

media.seek((parseInt(value/1000))*1000)

Did you check the value you get there ?

[Melle_87]

@SGaist : Yes, of course. The value is okay and is in range.
