Speculor v0.21.0

Install

Quick start (one download per platform)

Windows (x64) — speculor-0.21.0-windows-x64-full.zip. Extract and run speculor\speculor_app.exe.

Linux (x64) — speculor-0.21.0-linux-x64-full.tar.xz. Extract and run ./speculor/speculor_app.

Linux (ARM64) — speculor-0.21.0-linux-arm64-full.tar.xz. For ARM64 single-board computers (Raspberry Pi 5, Orange Pi 5 / RK3588). Extract and run ./speculor/speculor_app.

Custom install (pick the plugin domains you need)

Download the smaller speculor-0.21.0-<platform> archive plus any speculor-bundle-<domain>-0.21.0-<platform> archives, and extract them all at the same install root. Bundle domains: adsb, astro, audio, sdr, passive-radar, video-sources, motion-analysis, detection, image-filters, renderers, automation, mounts, scripting, output, database, data-filters, misc-sources, oss (open-source plugins: ViBe/SuBSENSE motion + RTL-SDR).

What's changed

Application

Features

• azimuth-finder: calibrate all-sky cameras from their image circle
• azimuth-finder: give the frame preview room and make the map aim readable
• tools: Live streaming in the Zone Editor, and window buttons on both editors
• engine: notify consumers when the pipeline starts and stops

Bug fixes

• azimuth-finder: solve camera pose on SO(3) so the zenith is not singular
• tools: close the defects the Live refactor introduced
• tools: convert 16-bit camera frames instead of scrambling them
• tools: review round 3 — button state, stale lists, and the BGR hot path
• azimuth-finder: qualify ptrdiff_t so the disc detector builds under gcc
• presets: reset params a preset predates to their descriptor defaults

Engine SDK

Features

• geo: describe all-sky cameras by their image circle

Plugins

Features

• camera: carry the all-sky image circle in frame metadata
• adsb: drop the FOV cone from the compass on an all-sky camera
• mounts: add Celestron NexStar mount control
• roi_filter: blur the masked region instead of blacking it out

Bug fixes

• mounts: stop a wrong serial port from freezing pipeline start
• mounts: match the shared target defaults to the descriptor
• mounts: correct the ZWO equatorial rate frame and stop the axis pulsing
• mount_director: carry the all-sky image circle into the view gate

What's changed

Application

Features

• engine: report per-port output consumers to plugins
• sapient: give net::Conn a bounded readiness wait

Bug fixes

• sapient: ignore SIGPIPE so a peer disconnect cannot kill the engine
• sapient: poll before accept so the HLDMM stop path cannot hang
• ci: skip the deploy phase so the gate ignores sibling repos
• sapient: bound the ASM reader so stop() cannot deadlock
• sapient: bound the HLDMM client loop without losing heartbeat eviction

Engine SDK

Bug fixes

• testing: stop the conformance suite asserting unreachable states
• build: stop flagging partially initialized structs under GNU

Bug fixes

• deps: declare OpenCV's real ISA baseline

Bug fixes

• packaging: build published bundles for a portable ISA baseline

Features

• testing: add a header-only plugin test harness
• cmake: add spc_add_plugin_test for harness consumers

Performance

• spclib: sweep the blob seam merge instead of scanning it
• spclib: flood fill blobs a run at a time, not a pixel at a time

Features

• sdk: tell plugins which output ports anything is reading

Performance

• spclib: halve Horn-Schunck's memory traffic per SOR iteration

Bug fixes

• package: make the SDK bundle relocatable and link OpenCV's jpeg

Features

• spclib: let Pcg32 callers choose where they enter the table

Bug fixes

• package: define the CURL target the SDK bundle's export requires

Performance

• spclib: align Pcg32 to a cache line to stop false sharing

Plugins

Features

• qhy_source: add opt-in per-phase frame timing
• sky_object_detect: add opt-in per-phase frame timing

Bug fixes

• object_classifier: stop demanding a class prior that is meant to be optional
• bbox_merger: keep frame number and timestamp on detection-free frames
• sources: make the ROI parameters readable
• database: report SPC_ERR_NOT_FOUND for unknown parameter names
• build: clear the build warnings, keep ncnn out of LTO

Performance

• optical_flow: skip the flow visualisation when nothing reads it
• optical_flow: skip the flow angle and the NVOFA visualisation when unread
• mog2_bgs,wmv_bgs: give the GPU shaders one row per workgroup
• image_stabilizer: skip the valid-region mask when nothing reads it
• sky_object_detect: extract blobs with contours by default
• sky_object_detect: extract blobs with spclib's detector by default
• sdr_spectrum: blend signal markers only over the columns they touch
• sdr_spectrum: stop reallocating the spectrum fill buffer every frame

Open-source plugins

Bug fixes

• vibe_bgs: stop every worker drawing the same random sequence

Performance

• vibe_bgs: give the GPU process shader one row per workgroup
• vibe_bgs: clear the GPU mask up front instead of per pixel
• vibe_bgs: write the GPU model a word at a time, not a byte at a time
