will it be frame accurate to use LAV decoder's Intel Quicksync option in avisynth?

I am trying to use intel quicksync to hw decode my h264 video for speed up. So far the only available source filter in avisynth I know of is by using LAV decoder's IQS option, and connect it to directshow using graphicstudionext like here:

The speed is very nice, but I was wondering whether this method was frame accurate?

Generally, DirectShow will not be reliably frame accurate.

You can try my new frame-accurate source filter for QuickSync:

I offer a free DG tools license to any Doom9 member wanting to participate in the development. Just send me a PM with your valid email address, to which I will send your activation. It works pretty good already and opens everything DGDecNV can open.
