Comment (by ericmcarson):

 Digimetrics fully complies with the LGPL with the current builds of Aurora
 & Hydra. We have confirmed this with our legal counsel.

 The FFmpeg website states that your checklist has additional requirements
 not listed in the LGPL.  “The following is a checklist for LGPL compliance
 when linking against the FFmpeg libraries.  It is not the only way to
 comply with the license, but we think it is the easiest.  There are also a
 few items that are not really related to LGPL compliance but are good
 ideas anyway.”  https://www.ffmpeg.org/legal.html.

 We appreciate you think the checklist is a good idea, but Digimetrics has
 licensed the LGPL, not the checklist, and has been advised by our legal
 counsel that we do not need to comply with the checklist except to the
 extent that the checklist requires items that specifically appear in the
 LGPL. If there is a particular section of the LGPL that you believe is
 violated, please identify it so we can know the basis for your complaint.

 Finally, even though the LGPL does not mention EULAs, in the spirit of
 cooperation and an effort to resolve this matter, the EULAs for the
 Digimetrics software Aurora and Hydra have been updated to separately
 identify the open source components of the Digimetrics software including
 the FFmpeg libraries, and state that these can be used subject to the
 rights of the owners of the open source software.   The emails that
 Digimetrics sends out with a hyperlink to our FTP server for file access
 have been similarly amended, as have the Help, About sections of our
 software.  While these steps were not necessary to comply with the LGPL,
 as you said, “these are good ideas anyway.”

 Updated EULAs for both Aurora & Hydra are attached. We will consider this
 issue resolved unless you have specific EULA sections you can point to
 being non-compliant with the LGPL.
