Question I can't control the video with the TrackBar1 scroller with Axvlc plugin c#

[omar7625]

I have tried axVLCPlugin21.input.time = trackBar1.Value; but to no avail

code.....

private void trackBar1_Scroll(object sender, EventArgs e)
{
    axVLCPlugin21.input.time = trackBar1.Value;
}

private void axVLCPlugin21_MediaPlayerTimeChanged(object sender, AxAXVLC.DVLCEvents_MediaPlayerTimeChangedEvent e)
{
    lb_START.Text = TimeFormat(e.time);
    trackBar1.Value = e.time;
}

private void axVLCPlugin21_MediaPlayerPlaying(object sender, EventArgs e)
{
    lb_END.Text = TimeFormat((int)axVLCPlugin21.input.length);
    trackBar1.Maximum = (int)axVLCPlugin21.input.length;
}

I would think that you'd want to handle the ValueChanged event.

That said, can you set the video position explicitly, without using a TrackBar? If not then the TrackBar is actually irrelevant to the issue.

Yes, I can set the video position without the TrackBar, but it's not accurate. When I try to advance the time by 90 seconds, it only advances 80 or 85 seconds, and sometimes time never advances.

This is a video explaining the problem...

public Form1()

            int hours = iTotalsecond / 3600;
            int hours_res = iTotalsecond - (hours * 3600);

            string strTimestring = String.Format("{0,1}:{1,2:D2}:{2,2:D2}", hours, minutes, seconds);
            return strTimestring;

        }

You already have a thread about this open. Merging threads...

Yes, I can set the video position without the TrackBar

But you figured that showing us that code for comparison would be a bad idea?

Sorry, but I just want to get a solution to my silly problem so I'm willing to share the project file with you if need be

 

[jmcilhinney]

We don't need or want the project file or the project as a whole. We want the code that is relevant to the problem. You say that you can get this to work by setting the field/property directly. Show us the code that does that, so we can compare it to the code you said doesn't work. If you'd like a solution to the problem, provide us with the information we need to solve it.

This is the code that works axVLCPlugin21.input.time = 90000; But not perfectly , by the way. The number represents a fraction of a second.

 

[jmcilhinney]

With regards to post #5, that TimeFormat method is a waste of code. Just create a TimeSpan and call its ToString method:

var timeText = TimeSpan.FromMilliseconds(milliseconds).ToString("h\:mm\:ss");

You might want to double check but I think that format specifier is correct.

So, you're saying that if you use a literal value of 90000 it works - some of the time, at least - but if you use trackBar1.Value and it's equal to 90000 then it never works? I don't see how that's possible. There must be something else different.

Yes, when I move TrackBar1.Value, time does not advance at all, as if something is running in the background to prevent time from responding to TrackBar1.Value.

This video explains the difference between using TrackBar.Value and button to specify a time value........ I hope to watch it

You still haven't posted a link to the video. Neither in post #4 nor #13.
