It's not just the mediaplayer (mplayer/VLC/Xine/whatever). Your entire system needs to be optimized. If you're playing a file from your hard drive, faster disk drive access helps. If you're streaming from the web, faster networking code helps. Most movies have sound. Faster alsa code helps. Video uses the X Window libraries. Speeding them up helps. There are a lot calls to the kernel. Speeding up the kernel helps. To summarize... your system uses dozens of libraries to render a movie. Optimizing one library may seem very minor, but it all adds up when you optimize every library on your system. -- Walter Dnes <waltd...@waltdnes.org>
