UPDATE: Engadget just wrote a reply to this article. The article says that you don't need an extra license to shoot commercial video with h.264 cameras, but I wonder why the license says otherwise, and Engadget's "quotes" of user/filmmaker indemnification by MPEG-LA are anonymous...
UPDATE 2: Engadget's editor replied to me. So according to him, the quotes are not anonymous, but organization-wide on purpose. If that's the case, I guess this concludes that. And I can take them on their word from now on.
UPDATE 3: And regarding royalties (as opposed to just licensing), one more reply by Engadget's editor.

Did you factor in the year that patent applicant have after initial publication to register?
Also, were patents pending at that time, and kept in the loop for as long as possible (back then, submarine patents still worked)?
I think that you actually need to wait until Dec 2012 in the US, since patents can be filed up to a year after initial publication, and the earliest publication that had practically all of MPEG-1 was the committee draft on December 6, 1991.
Note that patents could be delayed and so sometimes the patent lifetime could exceed 20 years in the US, but this does not seem to be the case for the patents I have found publicly listed for MPEG-2 (which should cover MPEG-1 video) and MP3.
If you don't care about MPEG-1 layer 3 audio (MP3), the rest of MPEG-1 may already be patent free or maybe after US 5214678 expires on May 31, 2010.
I have created a summary of this at:

and a fuller article at:

MPEG is also discussing the possibility of a royalty free codec. See:

Wait a year, use MPEG1. Far better than MJPEG, and in a year, the original reference implementation will have passed the time in which any patents applying to it could have expired. And use the good ol' Netscape 2.0 <embed>+HTML4 <object> combo.
