Hi

Great news regarding AVISynth development for Linux, the old version 3.0 is dead but a commercial movie distribution venture is moving it's infastructure from Windows to Linux and porting AVISynth to Linux.

It's already well under way, Doom9 members have been invited to port their plugins.

So question for now is there the ability to send AvxSynth frame served output to MLT Producer via stdout and into kdenlive and/or possibility to encode out via AvxSynth from kdenlive / melt.

And the big question ability to use AvxSynth as input/effects/filter/processing/export in a more integrated way. However appreciate there is no mac option here?

stout (and pipes / file descriptors in general) are probably not the most ideal solution for something like that. Using a combination of DBUS (to negociate terms of connections between processes as well as high level control / IPC) with Unix sockets (for data transfer and lowlevel transport control) would probably be much more productive. But the infrastructure for that would have to be designed and built first.

The reality is that will probably not happen if they are trying to make it cross platform between windows and linux. There is just not a good, opensource IPC / messing bus, or socket-like interface (aside from IP sockets) that is both efficient and common between the two systems.
