Save image from unmanage pointer

I use ffmpeg.autogen for receiving a frame from a video and want to continue to keep this frame in the picture. But I only get a pointer to the frame, how can I save it using Magic.Net? Bitmap was overloading the receive pointer to raw.

Example with Bitmap:

ffmpeg.sws_scale(
                this.pSwsContext,
                (byte*[])this.pDecodedFrame->data,
                (int[])this.pDecodedFrame->linesize,
                0,
                this.Height,
                (byte*[])this.scaledData,
                (int[])this.scaledLinesize);


            var data = new byte_ptrArray8();
            data.UpdateFrom(this.scaledData);
            var linesize = new int_array8();
            linesize.UpdateFrom(this.scaledLinesize);

            var bitmapFrame = new Bitmap(this.Width, this.Height, linesize[0], PixelFormat.Format24bppRgb, (IntPtr)data[0]);

@dlemstra Thank you, again!

The storage type should be Char and the pixel mapping BGR.
