Thanks.

Yes, it isn't there.

The marvell-ipp binaries we host for Fedora builds are not public.

olpc-os-builder can be configured to pull private resources, and the
Wiki page describes how that is done.

The marvell-ipp binaries we host for Android builds are public, as Ben
has said.  There's a license file in the same directory.

I doubt if the Fedora marvell-ipp binaries are distributable, given
how they are currently hosted, and the text of the Wiki page.  "These
are closed source libraries provided by Marvell."

No, I work for OLPC in Miami, in the United States, not OLPC
Australia.  I just happen to live in Australia.  ;-)  Confusing, I
know.

I understand.

Good to know.

Are there H.264 codecs and the like you can obtain from other places?
