The really silly part is that even if you have a license from MPEG LA for your product, you still have to put in a notice like this:

THIS PRODUCT IS LICENSED UNDER THE AVC PATENT PORTFOLIO LICENSE FOR THE PERSONAL AND NON-COMMERCIAL USE OF A CONSUMER TO (I) ENCODE VIDEO IN COMPLIANCE WITH THE AVC STANDARD ("AVC VIDEO") AND/OR (II) DECODE AVC VIDEO THAT WAS ENCODED BY A CONSUMER ENGAGED IN A PERSONAL AND NON-COMMERCIAL ACTIVITY AND/OR WAS OBTAINED FROM A VIDEO PROVIDER LICENSED TO PROVIDE AVC VIDEO. NO LICENSE IS GRANTED OR SHALL BE IMPLIED FOR ANY OTHER USE. ADDITIONAL INFORMATION MAY BE OBTAINED FROM MPEG LA, L.L.C. SEE HTTP://WWW.MPEGLA.COM

It's unclear whether this license covers videoconferencing for work purposes (where you are paid, but not specifically to be on that call). It seems to rule out remote tutoring.

MPEG LA probably did not have much choice here because this language requirement (or language close to it) for outgoing patent licenses is likely part of their incoming patent license agreements. It's probably impossible at this point to renegotiate and align the terms with how people actually use video codecs commercially today.

But it means that you can't get a pool license from MPEG LA that covers commercial videoconferencing, you'd have to negotiate separately with the individual patent holders.
