"Hello, i am trying to watch a video on Mac and it says that I need xvid video codec and i can't find it anywhere. i have downloaded perian and the VLC player but i don't know what to do after that. can anyone help me?"
Xvid is a MPEG-4 codec, much like x264 (AVC, used in most MP4s). However, unlike the latter, it uses the MPEG-4 Part 2 encoding standard. As a result, Xvid requires higher bitrates to achieve the same video quality as MP4. If 2 files of the same size were compared, the .xvid would lose. In addition, Xvid containers lack support for functions that would later be introduced in MP4 - most notably, subtitles.

You also need to add the gpl variant because xvid is licensed under the terms of the GNU General Public License (GPL) instead of FFmpeg which is licensed under the GNU Lesser General Public License (LGPL). When you have tried to use the command above to install FFmpeg you probably got an error back along the lines of:
concerning ffmpeg, the current version of ffmpeg does not require thevariants +gpl +lame +x264 +xvid as these are nowincluded by default. Please make sure that your ports tree is up to dateand just install ffmpeg without any variants
