[Ronald S. Bultje]

Hi,

I'll be gone for a few months (study), but will try to answer emails
once in a while... Here goes.

Ehm, we really have most of these. We have matroska muxers, xvid
encoders, video scalers, etc. I don't know what a splitter is, but we
probably have that too.

We have that, from ffmpeg. It's well optimized.

I have that in mjpegtools, GStreamer port is pending.

Same.

We have those.

Tee, we have that.

Those need to be written, yes. That's the work for the win32 port. :).
