Programs like GOM Media Player need certain software tools called “codecs” in order to interpret the data stored in video/audio files and play them back. GOM has all of the most essential video codecs built-in, so in most cases you won’t need to install anything extra in order to watch a video file.
There may, however, be some instances where you’ll want to play a video file that requires a codec that is not included with the installation of GOM Media Player. When this happens, the Codec Finder will automatically start and ask you if you want it to search for the codec that you need.
If you have a codec problem with another player, you may get a crash, or you may simply get an esoteric “codec not found” error message that doesn’t help you resolve the issue at all. GOM Media Player’s Codec Finder will inform you that a required codec is missing, and then it will support you in finding a solution.
By telling the Codec Finder to search for the missing codec, it will automatically determine what it needs, then provide you a page or a link that will explain the codec, and likely include a place where you can download the necessary codec for free.
This process saves the user the effort of trying to figure out what they need to do by themselves, and helps prevent users from uninstalling improper codecs on their system that my interfere with playback of other files.
While it does sound logical to include every codec we possible can with the default install, the fact is that most of those codecs will never be utilized by the vast majority of users, and including every codec would just add clutter and confusion to their systems. Furthermore, lots of codecs overlap and interfere with one another, which can cause playback problems for even the simplest, most common video file types.
For this reason, GOM Media Player includes all the necessary codecs to play all the most popular video file formats (AVI, MP4, FLV, WMV, etc), as well as the majority of the other somewhat less popular but still relatively common formats (MKV, OGM, 3GP, etc).
When you open a media file with GOM Media Player, it checks your system to make sure the proper codecs for playback are installed.
If a necessary codec is missing, the program will cross-reference that codec information (CodecGUID) with our database. The database tells the Codec Finder where that particular codec can be downloaded or provides the link to the user.
No other information (such as filename, file type, duration, user usage data, etc) is collected, sent, or stored by GOM Media Player.
