Pulsar gives you a live picture of what your pipeline is doing. The Pipeline Flow viewer is a node graph of every row, output and Orbit client, with edges that glow green while frames move — your everyday "is it flowing?" view.

The Pipeline Flow viewer

A separate, resizable window showing a live, read-only graph of your whole setup: each row's source → Video Processor → outputs / Orbit, with animated edges that turn green while frames are moving. Hover any node or edge for full specs, preview Orbit feeds, and start/stop outputs right from the graph.

How to open it

Click the Pipeline Flow button at the bottom-left of the footer (the three-connected-nodes glyph). It opens the window, or focuses it if already open.

• The glyph tints green when at least one row is pushing frames, grey when nothing is — a quick "are we live?" check without even opening the window.

Reading the graph

• Header read-out: N rows · M flowing — how many rows exist and how many are moving frames.
• Edge colours (the marching ants):
  • Green, animated — flowing, frames moving.
  • Amber — connecting.
  • Grey — idle, no frames.
  • Red — error.
• fps · bitrate labels ride on the slot edges; encoder chips (e.g. 12 Mb · h264) sit on the processing edges.
• Spec tooltips: hover any node or edge for codec, bitrate, fps, RTT, resolution and connection status.
• Capability warnings: an amber chip on a source or output flags a silent degradation (e.g. NDI 8-bit downconvert, or DeckLink HDR needing loopback to verify) — hover the node for the full explanation.

Privacy: the graph never shows SRT URLs, hosts/IPs, passphrase values (a set passphrase shows only set ✓), or Orbit access codes.

Confirm frames are flowing end-to-end

1. Open the Pipeline Flow window.
2. Read the header count: N rows · M flowing.
3. Scan the edges — green = moving, amber = connecting, grey = idle, red = error.
4. Hover a slot edge for live fps · bitrate; hover any node for its full spec.
