  • How to Install a Codec in Windows

    A codec is a device or program that has the ability to perform encoding and decoding on a digital data stream.Codecs are able to encode and decode files for viewing or editing a stream or signal for transmission, storage or encryption. They are often used in video conferencing and some streaming media applications.

    This was in an effort to compress files small enough to be readily transmitted across non-broadband networks and kept on slightly more expensive media, such as non-volatile memory and hard disk as opposed to formats such as CD-ROM and DVD.

    Many of the codecs around are designed to emphasize certain aspects of the media to be encoded. So a digital video (which would use a DV codec) of a news event, such as presidential elections or an international event, needs to be able to encode motion well but not necessarily exact colors.How to Install a Codec in Windows XP

    You can find well over hundreds if not thousands of codecs out there, and they range from those that are downloadable for free to those costing hundreds of dollars. This may cause some compatibility and obsolescence issues.

      Why doesn’t anyone answer the question of where are the codec’s physically in windows? what directory? what are the file extensions used? I replaced my drive, I can still access the old drive, I want the codecs from the old drive copied on to the new drive
