• Issue #1 when compiling Xuggler for Raspberry pi with libspeex

  23 juillet 2014, par Ashish Sharma

  I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian),

  I followed the ’Basic Build Instructions’ available here for compiling Xuggler.

  After I successfully installed all the prerequisites and set the correct paths, I ran the following command :

  ant run-tests

  After sometime I am facing the following error and the ant build fails :

  I am unable to understand the problem statment "unrecognized command line option ’-msse’" here, Can someone please tell me how can I resolve this or circumvent it in xuggler ?

• Why when using ffmpeg to create video file in real time the ffmpeg.exe take over 1GB of memory ?

          {
  
              p.Close();
  
          }
  
      }
  
  }

  ffmpegFileName contain the ffmpeg.exe

  Then i have a timer tick event in another form :

  ScreenShot shot = new ScreenShot();
  
      public static int counter = 0;
  
      private void timer1_Tick(object sender, EventArgs e)
  
      {
  
          counter++;
  
          shot.GetScreenShot(@"e:\screenshots\", "screenshot");
  
          if (counter == 1200)
  
          {
  
              timer1.Stop();
  
              ScreenShot.fmpeg.Close();
  
              this.Close();
  
              ScreenShotsPlayer ssp = new ScreenShotsPlayer();
  
              ssp.Show();
  
          }
  
      }

  This timer interval set to 100ms.
  So it’s taking a screenshot every 100ms.

  In the class ScreenShot i’m using the Ffmpeg class :
  In the top :

  public static Ffmpeg fmpeg;

  In the constructor :

  fmpeg = new Ffmpeg();
  
  fmpeg.Start(@"e:\screenshots\test.mp4", 25);

  Then in the GetScreenShot method i’m calling the Ffmpeg PushFrame method :

  public Bitmap GetScreenShot(string folder, string name)
  
      {
  
          _screenShot = new Bitmap(GetScreen());
  
          System.GC.Collect();
  
          System.GC.WaitForPendingFinalizers();
  
          string ingName = folder + name + Elgato_Video_Capture.counter.ToString("D6") + ".bmp";
  
          _screenShot.Save(ingName,System.Drawing.Imaging.ImageFormat.Bmp);
  
          fmpeg.PushFrame(_screenShot);
  
          _screenShot.Dispose();
  
          return _screenShot;
  
      }

  I can’t figure out why once i start the timer to take the screenshots the ffmpeg.exe eat so much memory also the hard disk is working about 53MB/s and the memory is over 90% and over 1GB.

  I’m doing the memory leak somehow ?

  

  In the ScreenShot class when i’m making an instance once for the Ffmpeg class the ffmpeg.exe is on very low memory usage and the hard disk usage is low.

  The ffmpeg.exe is about only 0.1MB of memory usage.

  fmpeg.Start(@"e:\screenshots\test.mp4", 25);

  But then when i’m clicking the button start the timer and taking screenshots every 100ms and calling PushFrame method the ffmpeg.exe very fast after few seconds getting to over 1GB of memory usage.

  EDIT

  I tried this arguments :

  psi.Arguments = @"-f rawvideo -pix_fmt bgra -video_size 1920x1080 -i \\.\pipe\mytestpipe -c:v libx264 -crf 20 -r 750k e:\screenshots\test.mp4";

  The memory usage was about 1gb of ffmpeg.exe and cpu usage 99-100%
  The hard disk was on 0 but now the cpu usage got to 100% and the memory over 1gb.

  And it didn’t create the video file I got this warnings/errors :

  

• Why i'm getting strange video file when using ffmpeg and pipes to create video file in real time ?

  30 juin 2015, par Brubaker Haim

  The goal here is to create a compressed mp4 video file in real time.
  I’m saving screenshots as bitmaps type on my hard disk.
  And i want to create mp4 file and compress the mp4 video file in real time.

  The problem is the end the video file i get looks very strange.
  This is the result : Strange Video File

  The class that i’m using the ffmpeg with arguments.

          {
  
              try
  
              {
  
                  int length;
  
                  // Lock the bitmap's bits.

                  int absStride = Math.Abs(bmpData.Stride);
  
                  // Get the address of the first line.
  
                  IntPtr ptr = bmpData.Scan0;
  
  
  
                  // Declare an array to hold the bytes of the bitmap.
  
                  //length = 3 * bmp.Width * bmp.Height;

                  //Marshal.Copy(ptr, rgbValues, 0, length);
  
                  int j = bmp.Height - 1;
  
                  for (int i = 0; i < bmp.Height; i++)
  
                  {
  
                      IntPtr pointer = new IntPtr(bmpData.Scan0.ToInt32() + (bmpData.Stride * j));
  
                      System.Runtime.InteropServices.Marshal.Copy(pointer, rgbValues, absStride * (bmp.Height - i - 1), absStride);
  
                      j--;
  
                  }
  
                  p.Write(rgbValues, 0, length);
  
                  bmp.UnlockBits(bmpData);
  
              }
  
              catch(Exception err)
  
              {
  
                  Logger.Write("Error: " + err.ToString());
  
              }
  
  
  
          }
  
  
  
          public void Close()
  
          {
  
              p.Close();
  
          }
  
      }
  
  }

  Then i’m using the method PushFrame here in this class :

  public Bitmap GetScreenShot(string folder, string name)
  
      {
  
          _screenShot = new Bitmap(GetScreen());
  
          System.GC.Collect();
  
          System.GC.WaitForPendingFinalizers();
  
          string ingName = folder + name +  images.counter.ToString("D6") + ".bmp";
  
          _screenShot.Save(ingName,System.Drawing.Imaging.ImageFormat.Bmp);
  
          fmpeg.PushFrame(_screenShot);
  
          _screenShot.Dispose();
  
  
  
          return _screenShot;
  
      }

  The Bitmaps on the hard disk are fine i can edit/open see them.
  When using command prompt and manually type ffmpeg command it does compress and create a mp4 video file.

  But when using the Ffmpeg class i did with the PushFrame method it’s creating this strange video file.

  This is a link for my OneDrive with 10 screenshots images files for testing :

  screenshots rar

  Sample screenshot from the video file when playing the video file :
  Looks very choppy. The Bitmaps on the hard disk each one is 1920x1080 and Bit depth 32

  But it dosen’t look like that in the video file :

  

  This is the arguments i’m using :

  psi.Arguments = @"-f rawvideo -vcodec rawvideo -pix_fmt rgb24 -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v mpeg4 -r " + BitmapRate + " " + outPath;

  The video size is very small 1.24 MB
