GOM Player is a free multimedia player that supports almost all major multimedia file types and allows additional codecs to be installed to increase its versatility. These codecs are small programs that allow decoding different types of video formats. For many types of encoded video files, GOM Player uses its own internal codecs, but sometimes these don't work as intended, or user adjustments have caused problems with their use. This is sometimes the case with the internal equivalent of the AC3 audio filter. Luckily AC3 is available for free and compatible for inclusion in GOM Player.
