Windows Handles number increases

MarcoM · Postby **MarcoM** » 24 Jun 2010 11:00

I use both Java (vlcj) and C# wrappers above libvlc 1.1.0 and I noticed that performing several stream rotation the number of Windows Handles grows continuously up to the crash of the process.
I cannot use a playlist but I have to use sequences of play/stop procedures because duration and URL of each played stream can change dinamically.
Any idea about this problem?
Note that I have the same behaviour with libvlc 1.0.x version and that the same problem can be generated performing several start and stop sequence with the VLC Player.
Thanks
Marco

Do you have a sample source code so we can try to reproduce this issue ?
Only a sequence of start/stop and it will crahs ?

This happens with the ActiveX control or calling native code in C#.

To test just drop the Ax control on a form and loop start/stop calls. Looks like 3-5 handles per loop.

Code: Select all

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;

namespace VlcActiveXTest
{
   public partial class Form1 : Form
   {
      long iteration = 0;

      public Form1()
      {
         InitializeComponent();
      }

      bool first = true;
      protected void RestartVideo()
      {
         textBoxOutput.Text = "Stream Start Iteration #" + iteration + " Done";
         try
         {
            Interlocked.Increment(ref iteration);

            if (!first)
            {
               this.axVLCPlugin21.playlist.stop();
            }
            else
            {
               first = false;
               this.axVLCPlugin21.playlist.clear();
               this.axVLCPlugin21.playlist.add(textBoxProxyUrl.Text, "test", ":file-caching=0");
            }            
            this.axVLCPlugin21.playlist.play();
         }
         catch
         {
            textBoxOutput.Text += Environment.NewLine + Environment.NewLine + "Error";
            buttonGo_Click(null, null);
         }
         finally
         {

         }
      }

      bool flipOn = true;
      private void buttonGo_Click(object sender, EventArgs e)
      {
         if (flipOn)
         {
            RestartVideo();
            timer1.Start();
            flipOn = false;
         }
         else
         {
            flipOn = true;
            first = true;
            iteration = 0;
            timer1.Stop();
            this.axVLCPlugin21.playlist.stop();            
         }
      }

      private void timer1_Tick_1(object sender, EventArgs e)
      {
         RestartVideo();
      }  
   }
}
