<DIV>I used <SPAN style="FONT-STYLE: italic">libdrm-2.4.27 </SPAN>which does not

<DIV><SPAN style="FONT-WEIGHT: bold">VAAPI</SPAN> still complains "<SPAN

<DIV>Add <SPAN style="FONT-WEIGHT: bold">#define PCI_CHIP_IVYBRIDGE_S_GT2

installed xf86-video-intel 2.19 which supports</DIV>

<DIV> </DIV>
<DIV>By the way,it seems little information with VAAPI except source
