Sometimes we get questions about if GStreamer can scale to handle really complex pipelines. Well thanks to Kipp Cannon and his talk at this years GStreamer Conference we know have the answer.
They are part of a research project called LIGO which is doing researching gravitaional waves, which can be described as ripples in the fabric of space-time. Kipp is part of the LIGO Data Analysis Software Working Group which has develop a what the call gstlal.
P.S. You might want to download and view the following with an image viewer application as the browser struggles to render it in any detail 🙂
Anyway, to make a long story short, their pipeline looks something like this image (created with the built in graph dump functionality of GStreamer using graphviz).
If you ever seen a bigger pipeline please let me know 🙂 Also it should alleviate any concerns you might have about GStreamers scalability.
