<!--QuoteBegin--><div class='quotetop'>QUOTE</div><div class='quotemain'><!--QuoteEBegin-->Our previous warning seems to be confirmed by latest announcement published by Milan Cutka (main FFDShow developer): "Don't use FFDShow-20050328! I was notified about new ffdshow build being available. I don't know who created it, but certainly he/she did a poor job."
"The whole package is build in Visual Studio .NET 2003 with Microsoft compiler in Release target. While this isn't bad choice for ffdshow.ax itself and several other libraries included in VS.NET solution, it's inapropriate for building libavcodec and libmplayer.dll. Those two libraries are essential for good performance of ffdshow - libavcodec for decoding/encoding most of video and audio formats and libmplayer for software scaling, many colorspaces conversions and fast mp3 decoder. When those two libraries are build by Microsoft's compiler, all hand optimized code developed to effectively use MMX, 3DNow and SSE extensions is skipped resulting in much worse performance. Use GCC from mingw packages to build them."<!--QuoteEnd--></div><!--QuoteEEnd-->
