Continuous Media Markup Language (CMML) is to audio or video what HTML is to text.[1] CMML is essentially a timed text codec. It allows file creators to structure a time-continuously sampled data file by dividing it into temporal sections (also called clips), and provides these clips with some additional information. This information is HTML-like and is essentially a textual representation of the audio or video file. CMML enables textual searches on these otherwise binary files.[2]
CMML is appropriate for use with all Ogg media formats, to provide subtitles and timed metadata.
CMML is deprecated; Xiph.Org Foundation recommends use Kate instead.
