Yeah, absolutely; most of us started with tasks to get us up and running
and familiar with this whole thing. You'll know when you're comfortable
doing that kind of stuff, and that's probably when it's the right time to
write your complete own demuxers (even if you don't think it is yet; it
should be a bit of a challenge, after all). There's always stuff to be done.
