Since we only support MJPEG quicktime, it only works for MJPEG. All
other formats would require re-encoding anyway.

There *is* no such utility yet. GStreamer is trying to become such a
utility, but development of such a utility takes a long time. It isn't
as easy as you'd like it to be.

GStreamer is on the good way, there's quite some sample applications
which work partly or fully, and there's another load of applications
currently being developped, some of which do exactly what you're looking
for (virtualdub-alike). But have patience, we aren't there just yet. For
now, mjpegtools is pretty much the only (set of) tool(s) which can do
what you're asking for.

Same goes for supporting broken AVIs ;-). Which is why we only support
non-broken AVIs :-).
