<h2>Changes</h2>
<ul>
<li>2.00 beta 7<ul>
<li>Using ffms2 as a library no longer requires an installed pixfmt.h from libavutil, it is however still required to compile ffms2 and the avisynth plugin part</li>
<li>Fix a crash bug at the end of files with b-frames in beta 6 caused by uninitialized null packets</li>
<li>Includes TheFluff's wrapper function for 1.21 style syntax</li>
<li>Added a simple regression test application to the source</li>
