Zoom integration. Convert YUVRawDataI420 -> RGB to show in texture

[AInsolence]

UPD: created in-place conversion [YUV 4:2:0 → RGB] but get an artefacts, kind of red ghosts of mine)

If someone knows a solution to fix it or some hints, would be great)

CODE:

    if (BufferSize != DataSize)
	{
		delete[] Buffer;
		BufferSize = DataSize;
		Buffer = new uint8[BufferSize];
	}

	for (int32 i = 0; i < DataSize/4; i++)
	{
		double Y = static_cast<uint8>(Video.Data->GetYBuffer()[i]);
		double U = static_cast<uint8>(Video.Data->GetUBuffer()[i / 4]);
		double V = static_cast<uint8>(Video.Data->GetVBuffer()[i / 4]);

		Y -= 16.0;
		U -= 128.0;
		V -= 128.0;

		// R
		Buffer[i*4] = FMath::Clamp(static_cast<int32>(Y * 1.0 + 1.140 * V), 0, 255);
		// G
		Buffer[i*4+1] = FMath::Clamp(static_cast<int32>(1.0 * Y - 0.395 * U - 0.581 * V), 0, 255);
		// B
		Buffer[i*4+2] = FMath::Clamp(static_cast<int32>(1.0 * Y + 2.032 * U), 0, 255);
	}
