A media codec is a software to compress and decompress a digital media file. The name codec itself is a short version of Encoding and Decoding which means compressing and decompressing of a media file. The codec includes two components, an encoder and a decoder. The encoder compresses the media file which can only be decoded by the same codec using its decoder component.
Unfortunately, we can’t predict which media codec has been used to encode a media file just by its extension. For example, a file with WMA extension can be encoded using WMA 7, WMA 9.2, WMA 10 etc. We will need the same codec which has been used to encode the file to decode and play it.
