Hi Stirling,

we are using WebVfx which can be useful to you but uses mlt instead of
GStreamer. Part of our pipeline uses GStreamer and I'm about to start
(currently researching and reading code) either an shm bridge between
melt and GStreamer or an element that wraps webvfx so it can be used
from gstreamer. Perhaps we can join efforts.

Best regards.
