<p>Since the libmpeg2 <a href="/facts/Source_code/o9J6Jv23">source code</a> library is released under free and open source license it is legally redistributable. However, the MPEG-2 compression algorithm method is owned by the <a href="/facts/MPEG_Licensing_Authority/b1NHuhdq">MPEG Licensing Authority</a> and are in some countries protected by <a href="/facts/Software_patent/wI6RrYh3">software patents</a>. Absent such a licence from the MPEG Licensing Authority, it could possibly be illegal in certain countries to distribute compiled versions of libmpeg2 for the purpose of decoding <a href="/facts/MPEG-1/ewnQQLPD">MPEG-1</a> and/or <a href="/facts/MPEG-2/SpuH5FJu">MPEG-2</a> video streams.
