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.
