Just wanted to provide some bits about the MPEG-LA AVC patent portfolio licensing (which includes H.264 enc&#x2F;dec). I went through this process for work and it&#x27;s pretty painless. The licensors are very responsive will help you find a solution. They&#x27;re not trying to shake you down.<p>(I&#x27;m not familiar with Vysor but whatever you do, stay away from libvlc if you&#x27;re looking for a decoder&#x2F;encoder. That stuff is not kosher in most countries. ffmpeg is a gray area too.)<p>Some highlights from a few years ago (may differ slightly now but unlikely):<p>* No licensing fee<p>* Free for private&#x2F;personal, non-commercial usage (e.g. non-monetized YouTube, cat videos)<p>* &lt; 100,000 units = no royalties! (Unit defined as encoder or decoder)<p>* &gt; 100,000 units = 0.20c&#x2F;unit<p>The process is simple, you ping them, they FedEx you a stack of easy to read papers, sign it, and mail it back.<p>[IANAL so obvious use-common-sense boilerplate goes here.]
