WEBM file format
Like the MKV file extension, the WEBM royalty-free extension is developed by various online parties such as Google, it is a freeware offering streaming of online video content and it was first developed in 2010. By using the HTML5 version of YouTube one can watch video encoded in WEBM.

When it comes to the Android support a version of 2.3 (Gingerbread) and above allowing playback of WEBM format can be used for encoding and decoding.

It provides open video compression for HTML5 videos and most major web browsers support WebM as a part of HTML5 video delivery.
