<h2>Changes</h2>
<ul>
<li>2.00 beta 9<ul>
<li>Now has stricter index checking to detect when different FFmpeg versions were used to create an inded of the same version</li>
<li>Fixed an access violation occurring when unindexed or empty audio tracks in matroska files were opened</li>
<li>Less type conversion/signedness warnings</li>
<li>When audio track dumping is performed a custom callback can now be supplied to name the tracks</li>
<li>The audio track delay is now exposed in the API in the same way as video tracks</li>
<li>A big type and argument name cleanup in the API, many things have been renamed to be clearer and it should be completely C friendly now</li>
<li>Removed FFNoLog and replaced it with FFSetLogLevel and FFGetLogLevel, the default logging is now also set to quiet, the magical numbers to supply it can be found in avutil/log.h</li>
<li>Updated FFmpeg to rev X</li>
<li>Updated FFmpeg to rev X (now with pthreads and faad2 again by popular demand, updated to GCC 4.4.0 for compiling all libraries)</li>
</ul></li>
<li>2.00 beta 8<ul>
