Many major media players have their own DivX support. DivX video files are also played by many hardware players. The lion's share of multimedia players can recognize the DIVX file type and open correctly to play .divx files. Only occasionally do you have to change the extension to .avi.
ALAC is the format of a small specialized program called an audio codec. Its main task is to compress a file with digital music without losing its quality. The name of the format created by Apple's IT giant is Apple's abbreviation Lossless Audio Codec. This format may also be called ALE (from Apple Lossless Encoder). Files in this format can play devices even with limited computing resources - such as an iPod. When compressing a file in this format, it is approximately 40-60% of the original file. Now almost every multimedia player based on the libavcodec library is able to play ALAC format files.
