I am trying since yesterday... Ok I can create WriteableBitmap, but later I can't save it using MediaLibrary, I get System.InvalidOperationException, I was told it is because of incorrectly created WriteableBitmap. — user963935

The only way I know on Windows Phone is using the WriteableBitmapEx library. In addition to WriteableBitmap it implements an "SetPixel method with various overloads":

The Library can simply be installed from within Visual Studio 2012:

PROJECT => Manage NuGet Packages => Online => Search for "WriteableBitmapEx"

You may use copyTo member function of int[] for copying int[] to WriteableBitmap.

int[] ARGBPx = new int[(int)captureDevice.PreviewResolution.Width * (int)captureDevice.PreviewResolution.Height];            
WriteableBitmap writeableBitmap_preview;        

ARGBPx.CopyTo(writeableBitmap_preview.Pixels, 0);         
writeableBitmap_preview.Invalidate();
