<p>Hi <span
style="font-family: book antiqua, palatino; font-size: 13pt;">Edward,</span></p>
<p><span
style="font-family: book antiqua, palatino; font-size: 13pt;">No
royalty is paid, but donations are welcome. Axon, DVR Examiner,
Amped, entities that distribute FFmpeg binary or </span><span
style="font-family: book antiqua, palatino; font-size: 13pt;">distribute
their own closed source binary that links to </span><span

must</span></p>
<ul>
<li>make an offer for the GPL source code used</li>
<li>enclose a copy of the GPL license along with the product.</li>
<li>supply compiling instructions.<br>
</li>
</ul>
<p>to each end user of <span
style="font-family: book antiqua, palatino; font-size: 13pt;">Axon,
DVR Examiner, Amped, etc. I would say these are the most
important, but <a href="https://www.ffmpeg.org/legal.html"
moz-do-not-send="true">FFmpeg legal</a> has a complete list.
Many companies completely violate FFmpeg's licensing terms
including Bluesound / Lenbrook for the past 14 years.<br>

I am writing a white paper on forensic video analysis and the
software solutions many analyst throughout the world rely on for
their examinations. </div>

In the white paper, I discussed open source solutions as well as
commercially available software (sold to consumers) who
incorporate FFMpeg open source solutions such as the ffmepg
libraries into their commercial paid for software. Three such
companies are; </div>
<div class="default-style"

<ul>
<li class="default-style"
style="font-size: 13pt; font-family: andale mono,times; color: #333333;"><strong>Axon</strong>;
they sell a software program called "Axon Investigate"...
formerly owned by Occam Solutions and sold as "Input Ace"</li>
<li class="default-style"
style="font-size: 13pt; font-family: andale mono,times; color: #333333;"><strong>DVR
Examiner</strong> now owned by Magnet Forensics and,</li>
<li class="default-style"
style="font-size: 13pt; font-family: andale mono,times; color: #333333;"><strong>Amped</strong>
(sold internationally out of Italy)</li>
</ul>
<div class="default-style"
style="font-size: 13pt; font-family: andale mono, times; color: #333333;">
Given all three of these companies generate millions in sales
each year, do they pay or have to pay any fees or royalties? </div>
