The stream conversion now runs on the GC880 when the image carries the GL stack, and /cam/h264 serves the same picture as fragmented MP4 in a fraction of MJPEG's bytes (forgectrl 6573abd). This side supplies what that needs and holds it to account: - Distro: opengl stays a feature, with mesa trimmed to exactly the path used (gallium etnaviv, GLES/EGL/GBM, no GLX, no display platforms). Image: libegl-mesa, libgles2-mesa, libgbm, mesa-megadriver. forgectrl dlopens them, so an image without them still streams on NEON. Platform change: the next campaign is full. - forgetest: camera.h264-stream exercises the endpoint end to end (codec header, init segment, media fragments, /cam/status encoder state) and accepts a clean 503 on a machine without the stack; the camera covers name the new forgectrl files. - VIDEO.md 5.6 now describes both streams and why H.264 earns its place (the WiFi transmit path measures about 7 percent of the core per MB/s sent); BRINGUP records the bench-validation checklist as Next work item 20, including the release-size watch: mesa must fit the 200 MiB slot gate.

|
|
|
# ForgeFIRM cuts the cloud dependency: drop the Glowforge cloud client
|
|
# (gfui-client connects to Glowforge's servers). Removing it here (override
|
|
# only; the shared glowforge-image base is untouched) also sidesteps its
|
|
# do_package failure. Its role is filled locally by forgectrl and the
|
|
# controllers below (kas/README.md backlog #6).

# grblhal-glowforge: the grblHAL motion controller (Grbl over TCP:23).
|
|
# forgectrl: the ForgeFIRM machine-services daemon (HTTP :8080): controller
|
|
# supervisor, pulse-device broker, cooling engine, cameras, telemetry,
|
|
# settings, diagnostics, web control panel, and A/B updates.
|
|
# gfhome: one-shot Glowforge web-service homing, invoked by the controller
|
|
# for $H when homing_mode = gfcloud (/data/forgefirm.conf).
|
|
# gfcloud: full Glowforge web-service controller daemon (the factory cloud
|
|
# experience), started when controller_mode = cloud - mutually exclusive with
|
|
# grblHAL. Pulls python3-ffmachine (shared web-service machine glue).
|
|
# v4l-utils provides media-ctl / v4l2-ctl for the imx-media pipeline (also a
|
|
# forgectrl runtime dependency, kept explicit here for bring-up use).
|
|
# fwup: applies signed .fw archives (ForgeFIRM upgrades + factory restore)
|
|
# to the inactive rootfs slot.
|
|
# ffboot: boot-slot inventory and switching (also ships fw_env.config).
|
|
# slotmigrate: boot-time reclaim of the legacy p4 layout (grows /data).
|
|
# forgefirm-logging: the ForgeFIRM logging tree - renders the per-logger
|
|
# rsyslog rules from the settings before rsyslog starts, and drives
|
|
# size-capped rotation (boot + hourly; a full /data breaks settings,
|
|
# updates, and controller writes). rsyslog itself comes in through
|
|
# VIRTUAL-RUNTIME_base-utils-syslog (conf/distro/forgefirm.conf).
