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.
