Combined Community Codec Pack

I preferred to use K-Lite Codec Pack. However the problem with codec packs is that one needs to use them carefully. If you only play videos on your computer, you may not notice any problems. Otherwise say video editing software may stop working.

I prefer to use VLC player, because it has built-in codecs. And you can use it in Windows as well as in Mac OS and Linux.
