Since 2017, Icecast — a streaming media server traditionally used for audio streaming — has supported live video streaming using the WebM format (VP8/VP9 video codecs with Vorbis/Opus audio codecs).https://web.archive.org/web/20170606103556/http://dir.xiph.org/by_format/WebM This enables broadcasting of high-quality, royalty-free, open-standard video streams that can be played directly in browsers without requiring proprietary plugins or players.

Archived streams and server listings demonstrate WebM's viability for live streaming over Icecast, including examples of 1080p VP9 streams. Current implementations include live streams accessible at [https://rdst.win:59000/dos.webm https://rdst.win:59000/dos.webm],https://rdst.win:59000/dos.webm with server status visible at [https://rdst.win:59000 https://rdst.win:59000].

Licensing

The original WebM license terminated both patent grants and copyright redistribution terms if a patent infringement lawsuit was filed, causing concerns around GPL compatibility.

In response to those concerns, the WebM Project decoupled the patent grant from the copyright grant, offering the code under a standard BSD license and patents under a separate grant.{{citation |url=http://webmproject.blogspot.com/2010/06/changes-to-webm-open-source-license.html |title=Changes to the WebM Open Source License |date=June 4, 2010 |first=Chris |last=DiBona |publisher=WebM |access-date=June 4, 2010 |archive-date=July 20, 2012 |archive-url=https://archive.today/20120720203109/http://webmproject.blogspot.com/2010/06/changes-to-webm-open-source-license.html |url-status=live }} The Free Software Foundation, which maintains The Free Software Definition, has given its endorsement for WebM and VP8{{citation |url=https://www.fsf.org/news/free-software-foundation-statement-on-webm-and-vp8 |title=Free Software Foundation statement on WebM and VP8 |date=May 19, 2010 |publisher=Free Software Foundation |first=Matt |last=Lee |access-date=April 15, 2020 |archive-date=August 7, 2020 |archive-url=https://web.archive.org/web/20200807183741/https://www.fsf.org/news/free-software-foundation-statement-on-webm-and-vp8 |url-status=live }} and considers the software's license to be compatible with the GNU General Public License.{{Cite web |url=https://www.fsf.org/blogs/licensing/googles-updated-webm-license |title=Google's updated WebM license |publisher=Free Software Foundation |first=Brett |last=Smith |access-date=June 14, 2010 |archive-date=June 7, 2010 |archive-url=https://web.archive.org/web/20100607031023/http://www.fsf.org/blogs/licensing/googles-updated-webm-license |url-status=live }}{{Cite web |url=https://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses |title=Various Licenses and Comments about Them – GNU Project – Free Software Foundation (FSF) |publisher=Free Software Foundation |access-date=June 13, 2010 |archive-date=July 24, 2010 |archive-url=https://web.archive.org/web/20100724023833/https://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses |url-status=live }} On January 19, 2011, the Free Software Foundation announced its official support for the WebM project.{{Cite web |url=https://www.fsf.org/news/supporting-webm |title=No double standards: supporting Google's push for WebM |publisher=Free Software Foundation |first=Brett |last=Smith |access-date=January 19, 2011 |archive-date=January 21, 2011 |archive-url=https://web.archive.org/web/20110121201447/http://www.fsf.org/news/supporting-webm |url-status=live }} In February 2011, Microsoft's Vice President of Internet Explorer called upon Google to provide indemnification against patent suits.{{cite web |url=http://blogs.msdn.com/b/ie/archive/2011/02/02/html5-and-web-video-questions-for-the-industry-from-the-community.aspx |title=HTML5 and Web Video: Questions for the Industry from the Community |date=February 2, 2011 |access-date=February 22, 2011 |archive-date=February 20, 2011 |archive-url=https://web.archive.org/web/20110220153727/http://blogs.msdn.com/b/ie/archive/2011/02/02/html5-and-web-video-questions-for-the-industry-from-the-community.aspx |url-status=live }}
