As such, a significant <a href="/wiki/Reverse_engineering" title="Reverse engineering">reverse engineering</a> effort is part of libavcodec development. Having such codecs available within the standard libavcodec framework gives a number of benefits over using the original codecs, most notably increased <a href="/wiki/Software_portability" title="Software portability">portability</a>, and in some cases also better performance, since libavcodec contains a standard library of highly optimized implementations of common building blocks, such as <a href="/wiki/Discrete_cosine_transform" title="Discrete cosine transform">DCT</a> and <a href="/wiki/Color_space" title="Color space">color space</a> conversion. However, while libavcodec does strive to achieve decoding that is bit-exact to their official format implementations, occasional bugs and missing features in such re-implementations can sometimes introduce playback compatibility problems for certain files. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Implemented_video_codecs">Implemented video
