Capture Flash Video

[pchen]

Is there a way capture a frame from the running flash video? Do you have any sample code?

Thanks,

Thank you for your question.

Yes, it's possible. Just create f_in_box__control with TransparentMode = true and handle OnFlashPaint event, something like that:

Code: Select all

[DllImport("Kernel32.dll", EntryPoint = "RtlMoveMemory")]
private static extern void CopyMemory(IntPtr Destination, IntPtr Source, int Length);

private void flashControl1_OnFlashPaint(object sender, IntPtr pPixelPointer)
{
     BitmapData bmd = bitmap1.LockBits(new Rectangle(0, 0, width, height), ImageLockMode.WriteOnly, PixelFormat.Format32bppArgb);

      int StrideSize = width * 4;

      for (int i = 0; i < height; i++)
      {
        IntPtr s = new IntPtr(pPixelPointer.ToInt32()+StrideSize * i);
        IntPtr d = new IntPtr(bmd.Scan0.ToInt32() + (StrideSize * (575 - i)));
        CopyMemory(d, s, StrideSize);
      }

      bitmap1.UnlockBits(bmd);
    }
}

I also find that I can use the following code.

Bitmap frame = this.f_in_box__control1.GetBitmap();

But for capture every frame, your solution is better.

Many Thanks.
