Here we will talk only about correcting this error in relation to Skype and Windows XP, if suddenly, the same problem you have arose in a newer OS or another program, go to the last section of this manual.
First of all, as I noted above, you do not need to perform actions to download dxva2.dll from the Internet or copy from another computer with a newer version of Windows, where the default file is in stock, instead of correcting the error you will only receive a message about that the "application or library DXVA2.DLL is not a manner for Windows NT."
In order to remove the error message "Failed to Load Library DXVA2.DLL" in Windows XP, it is enough to perform the following steps (I assume that you have Windows XP SP3 installed. If an earlier version, update):
- Check that all the necessary system updates are installed (install the automatic installation of updates to the control panel - automatic update.
- Install Windows Installer 4.5 redistributable from the official Microsoft website (this step is not always needed, but it will not be superfluous). You can download it in the "Loading Installer Windows 4.5 on the https://support.microsoft.com/en-us/kb/942288/en page. To restart a computer.

After performing these actions, in the specified order, the Skype service system will start without errors associated with the lack of DXVA2.DLL file (in case of continuing problems at startup, additionally note that DirectX and video card driver are installed in the system). By the way, the dxva2.dll library itself in Windows XP will not appear, despite the fact that the error will disappear.
Additional information: I recently had the opportunity to use Skype online without installing on a computer, it can be useful if nothing comes out (or you can download the old Skype version, just be careful and check the downloaded files, for example, on virustotal.com). Well, in general, I would recommend moving all the same on modern versions of Windows, since programs that run with problems in XP will be more and more.
