There are a set of patches for add some improvements for SandyBridge/IvyBridge Intel GPUs. This still actual for SNB GPU. The latest drivers for IVB/Haswell doesn't include the old DXVADDI_Intel_ModeH264_E device and doesn't experience the issue but SNB still.
See discussion https://lists.libav.org/pipermail/libav-devel/2013-March/043945.html for more info.
The main issue is h264 with refs > 11 decoded on DXVADDI_Intel_ModeH264_E device with artifacts. And solution is use standard Microsoft H264 device DXVA2_ModeH264_E but decoding with Microsoft H264 on SNB will no work without this improvements.
This still actual for lastest git-master.
