Hello,<br>I see that support for vaapi is not in ffmpeg and vlc.<br>I took ffmpeg-0.8.5-2.fc16.src.rpm and vlc-1.1.12-1.fc16.src.rpm from rpmfusion and recompiled them on my F16 system.<br>I&#39;m far from an rpmbuild expert and all conditional statements inside them, so I tried putting in spec files<br>


- $ diff ffmpeg.spec ffmpeg.spec.orig <br>123,124c123<br>&lt;     --disable-stripping \\\<br>&lt;     --enable-vaapi<br>---<br>&gt;     --disable-stripping<br><br>and<br><br>- $ diff vlc.spec vlc.spec.orig <br>324d323<br>


&lt;     --enable-libva            \<br>343c342<br>&lt; ##%{!?_without_mozilla:--enable-mozilla}        \<br>---<br>&gt; %{!?_without_mozilla:--enable-mozilla}        \<br>560,564c559,563<br>&lt; #%{!?_without_mozilla:<br>


&lt; #%files -n mozilla-vlc<br>&lt; #%defattr(-,root,root,-)<br>&lt; #%{_libdir}/mozilla/plugins/libvlcplugin.so<br>&lt; #}<br>---<br>&gt; %{!?_without_mozilla:<br>&gt; %files -n mozilla-vlc<br>&gt; %defattr(-,root,root,-)<br>


&gt; %{_libdir}/mozilla/plugins/libvlcplugin.so<br>&gt; }<br><br>(basically
 I didn&#39;t accomplish how to compensate a problem with firefox headers 
that prevented compilation, so I just disabled firefox plugins at all 
for my initial purpose...)<br>
<br>Then<br>yum reinstall :<br>sudo yum reinstall ffmpeg-0.8.5-2.fc16.x86_64.rpm ffmpeg-libs-0.8.5-2.fc16.x86_64.rpm <br>sudo yum reinstall vlc-core-1.1.12-1.fc16.x86_64.rpm /vlc-1.1.12-1.fc16.x86_64.rpm<br><br>It seems all is ok on my system that is an Asus laptop U36sd with intel corei7 and sandy bridge<br>
