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.
docs/VIDEO.md is the user-facing camera guide: what the endpoints return, what
the sensors can do that ForgeFIRM does not send and why, the privacy gate, and
the state of 8 MP support.
The 8 MP (OV8856) capture path now reaches the sensor's full 3264x2448 frame.
Its stock RAW10 full-resolution mode runs the link at 1.44 Gbps/lane and the
i.MX6 CSI-2 D-PHY stops at 1 Gbps; the BSP adds a RAW8 mode that carries the
same frame at half the rate, so an HD machine is no longer limited to the
binned quarter-pixel mode. kas/README.md carries the reasoning, the register
deltas and the factory configuration to fall back to if the receiver will not
lock at 720 Mbps/lane.
Acceptance: camera.sensor-profile expects the new OV8856 geometry, the camera
covers map names src/camhealth.* (the src/cam.* glob does not match it, so the
lint would have gone quiet on an uncovered file at the next pin bump), and a
new auto test camera.frame-health asserts a burst of captures with no frames
the capture queue flagged errored - a real signal about the camera ribbon even
though those frames never reach a client.
