Hi David, you are following the right thing. Yes, it appears Alex finished
the summer by implementing his multithreading code in the h.264 encoder and
decoder, which is absolutely great news. Also great is the fact that he's
implemented it in multiple other codecs and his approach can be extended to
all of the rest. It's really anyone's guess when it will be in ffmpeg
trunk, though. We've reached the GSoC "pencil's down" date and the first
patches for actual trunk from other participants have been submitted and
committed. In my opinion the multithreading changes are by far the most
ambitious of the summer, so it may take some time to get through the...
erm... *thorough* ffmpeg patch approval process. I hope it's soon, too.
It's probably going to come down to a) how clean is the code/how in line is
it with ffmpeg go-to dev styles, b) how persistent will he be in making
requested changes and c) how soon after that will there be another myth

You are correct, the C2 units come with a firmware (the 1.0B as of this
writing). Updating of the firmware to new versions will still require
windows for the time being, however. And based on some stuff that I've
heard today, we will probably be doing that very VERY soon. ;)
