Play MKV RMVB FLV MP4 in Windows Media Player Codec
With the increasing popularity of different video formats such as Rmvb, Mkv, Flv, Mp4, Flac and Xvid, numerous video players continuously appear on the market to meet the demand. Well, most people would prefer to stick to just one video player. The best one would be Windows Media Player that was pre-installed in your Windows OS.
By default, Windows Media Player does not have the ability to play video in formats such as Rmvb, Mkv, Flv, Mp4, Flac and Xvid. Windows Media Player will need a key or a set of instructions to be able to play such files, and we call it codec.
There are several Windows Media Player compatible codecs available on the internet for free. We will list only the most popular ones among hundreds of them. However, we do not guarantee that it will work. You will have to try with other codecs if those listed below don’t work for you.
