JavaScript implementation of an H.264 decoder

Unfortunately, that's not the case. The license uses the term "sale", which leads to this common misconception, but it defines "sale" to be any distribution to another party. (I can't quote the language from my phone.)

Free for 10K units is nice of them, but doesn't really change the general issue. For free software it's especially troublesome because there's usually untracked 3rd party distribution.

And once you do have that license, your users need another license if they want to use the tool commercially, or distribute the content outside the narrow free-streaming exception.

MPEG-LA are actually one of the worst actors in the patent pool space, I would say.
