    v1.4.2 — Viewer Auto-Open Hotfix Stable

    jkaindl released this 2026-05-27 06:25:24 +00:00 | 64 commits to main since this release

    Pre-v1.4.2, autosplat process opened SuperSplat in the browser with ?load=http://127.0.0.1:8765/scene.ply but never actually started a server on port 8765 — SuperSplat tried to fetch, silently failed, and the editor opened blank. Drag-and-drop the file manually was the only workaround. The pattern existed since the earliest CLI but was first surfaced by the real-world v1.4.0 max_strasse rescue run (5 h 36 min total, 490/493 cams = 99.4 %, then SuperSplat opened empty).

    Fixed

    • viewer.open_in_viewer now actually serves the PLY. For remote targets (supersplat / playcanvas) the function wraps serve_directory() around the browser-open and blocks on a threading.Event that a SIGINT/SIGTERM handler sets — so the local HTTP server stays up as long as the user wants to look at the splat, then shuts down cleanly when they press Ctrl-C. Console prints the viewer URL + PLY URL upfront so the user knows what's running.

    Changed

    • pipeline.run_pipeline no longer calls the viewer. Blocking inside the pipeline orchestrator would stall the watch-folder daemon between captures and prevent the WebUI's JobRunner from marking jobs done. CLI commands (process, resume, add-video, rescue) now invoke a new _open_viewer_if_configured() helper after their Done summary, so the user sees the result first and then learns the server URL. Daemon and WebUI already had the same broken viewer path — removing it there is a no-op for users (it was never opening anything anyway).

    Tests

    • 2 new end-to-end viewer tests: one verifies serve_directory is actually called inside open_in_viewer; the other fetches the PLY over HTTP from the running server to prove the bytes are reachable.
    • test_cli_rescue gets test_rescue_invokes_viewer_after_done verifying the wiring at the CLI layer.
    • Removed three obsolete patch("autosplat.pipeline.viewer_mod.open_in_viewer") in test_pipeline (the attribute no longer exists).
    • 311 tests passing, ruff clean, mypy clean on viewer.py + pipeline.py.

    UX note

    autosplat process video.mp4 now blocks at the very end with a console message:

    Viewer: https://playcanvas.com/supersplat/editor?load=…
Serving PLY at http://127.0.0.1:8765/scene.ply. Press Ctrl-C when finished to stop the local server.

    To opt out — e.g. for CI runs or when SuperSplat is started manually — set [viewer] auto_open = false or [viewer] target = "none" in the config.
