great, i didn't know of lavpipe. But:

In the documentation i only found references to "transist.flt",
as i understand it this only enables the third effect i
mentioned, for the others i'd have to write a filter, correct?
It seems that writing a filter is not impossible, looking at
the sources.
Is anybody working on other filters?
Is there an option to "glav" to display the actual frame number?
This would be extremely useful and it shouldn't bother others
who don't need that value.
I think the following filters could be useful, the first two
should be quite easy, the third may be a challenge if you want
good quality:
1.
Is anybody using "blenderpublisher" (www.blender.org)? It can
generate animations with background "invisible". I'd like to
overlay those over an AVI as an animated logo. As an
alpha channel is only available in single pictures, it would have
to read in a LAV stream and single pictures.
2.
I'd like to record myself twice, once in the left half of the
screen, once in the right half and then mix it together to
be in a single AVI twice.
3.
Bluescreen overlay.
What do you think of this?
Best regards,
Torsten.
