iOS Question VideoPlayer Position Issue

[cooperlegend]

I am using VideoPlayer in the iPad version of my App, Videoplayer reports back position of the video in 1 second increments (1000,2000 etc)

But when I try to set the Position it will round up or down to the nearest 10 seconds.

Is there a way to make this more accurate (i.e. to the closest second)

The parameter is specified in millseconds, it would nice if I could be more accurate with getting or setting the position of the video playing.

The video controller interval is not configurable. You can disable the controller and implement your own.

Thanks Erel

I don't use the controller anyway, I have implemented my own slider bar to track and set the position of the video, but it just jumps to the nearest 10 seconds.
How do I implement my own that controls the video to smaller increments?

Post the slider ValueChanged code.

 

[cooperlegend]

Sub slideVideo_ValueChanged(Value As Int)
    vpAnim.Position = vpAnim.Duration * Value / 100
    lblTime.Text = NumberFormat2(vpAnim.Position / 1000, 1, 2, 2, True)
    tmrVideo.Enabled = True
End Sub

What is the output of Log(vpAnim.Duration * Value / 100) when you move the slider? Post the logs.

As you can see the issue isn't with the Value passed to ValueChanged, that is correct.
But when you set vpAnim.Position to this value it jumps to the nearest multiple of 10,000 and sets Position to the nearest 10 seconds (rounding up or down)

Interesting discussion about this issue: https://stackoverflow.com/questions/11462843/avplayer-seektotime-does-not-play-at-correct-position

The behavior depends on the video source and encoding.

SeekWithNoTolerance:

Sub SeekWithNoTolerance (Position As Int)
    Dim controller As NativeObject = VideoPlayer1
    controller = controller.GetField("controller")
    Dim no As NativeObject = Me
    no.RunMethod("SeekWithNoTolerance::", Array(controller, Position))
End Sub

#if OBJC
- (void)SeekWithNoTolerance:(AVPlayerViewController*)controller :(int)Position {
    int32_t timeScale = controller.player.currentItem.asset.duration.timescale;
    CMTime time = CMTimeMakeWithSeconds(Position / 1000.0, timeScale);
    [controller.player.currentItem seekToTime:time toleranceBefore:kCMTimeZero toleranceAfter:kCMTimeZero];
}
#End If

Thanks Erel

That works great and gets around the problem

Appreciated
