&lt;div&gt;=Introduction=&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Matroska/матрёшка&#039;&#039;&#039; is an extensible open standard audio/video container format for various video and audio codecs. Matroska is based on [[EBML]], a binary variation of XML. It&#039;s aim is to replace the ageing [[AVI]] format and be a powerful alternative to other container formats like [[ASF]], [[MP4]], [[MOV]], RM, MPX and [[Ogg|Ogg/OGM]]. It can store Audio Only, Video Only, or both, and is free for personal use.&lt;br /&gt;
