Continuous Media Markup Language (CMML) is to audio or video what HTML is to text. CMML is essentially a timed text codec. It allows 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.
CMML is appropriate for use with all Ogg media formats, to provide subtitles and timed metadata.
Example of CMML Content
<cmml> <stream timebase="0"> <import src="galaxies.ogv" contenttype="video/ogg"/> </stream> <head> <title>Hidden Galaxies</title> <meta name="author" content="CSIRO"/> </head> <clip id="findingGalaxies" start="15"> <a href="http://www.aao.gov.au/galaxies.anx#radio"> Related video on detection of galaxies </a> <img src="galaxy.jpg"/> <desc>What's out there?</desc> <meta name="KEYWORDS" content="Radio Telescope"/> </clip> </cmml>
