A very useful program that checks the audio or video file indicated by the user for the required codecs and filters necessary to play it. In addition to codec names, the program displays a number of additional information about files - resolution, aspect ratio, speed, frame rate, quality (compression), number of audio channels. Additionally, if there is no codec installed in the system, which is necessary to play the checked file, the program indicates a page from which it can be downloaded (except that in most cases these are so-called codec-packs - sets of codecs).

AVIcodec also displays a list of all currently installed codecs and filters. Supported formats are: AVI, ASF, WMV, Real (.

rm, . rmvb), Ogg (. ogg, .

ogm), Mpeg-(S)VCD-DVD (. mpg, . vob).
