Kurento records a call into .webm format

what is webm? WebM is defined as a video and audio container format to provide high quality, royalty-free, open video compression for use with HTML5 video. The WebM container is based on a profile of Matroska. WebM initially supported VP8 video and Vorbis audio streams. In 2013 it was updated to accommodate VP9 video and Opus audio.
