ACE Mega Codec Pack is a complete codec pack that comprises a range of codecs, audio and video filters that let you play almost any multimedia file. The tool offers you multiple installation modes; “just play” being the simplest of the options available. This is a very basic deployment package. There is also ‘professional mode’ that packs in pretty much everything to churn out a smooth and clean media playback experience. Besides codecs, the program also offers BS Player to play different multimedia files.
