You can set up exec_push with ffmpeg at your incoming application and republish
your stream to another application with any change, including size change.
Something like this should work:
application /src {
live on;
exec_push ffmpeg -i rtmp://localhost/src/$name -c:a copy -c:v libx264
-s 640x480 -f flv rtmp://localhost/dst/$name;
}
application /dst {
# proceed here
}
