Two plugins the micro duck robot needs and no archive provides: `libgstrockchipmpp.so` for hardware H.264 through Rockchip MPP, and `libgstrswebrtc.so`/`libgstrsrtp.so` for webrtcsink. Debian ships no Rockchip encoder in any suite, Radxa's prebuilt plugin is decode-only (measured on a Zero 3W: mppvideodec and mppjpegdec, nothing else — 1.14.4 predates the encoders), and gstreamer1.0-plugins-rs exists in no Debian suite at all. `webrtcbin` is deliberately absent: Debian has it. Native arm64 in a debian:trixie container, which is the point. The daemon cross-compiles with cargo-zigbuild and its one C dependency is already the documented cost of that; GStreamer would be a far larger second one, and both routes — x86 multiarch or a sysroot with a meson cross file — link against an approximation of the target rather than the target. Here nothing is approximated. Public because arm64 runners are free on public repositories, and more importantly because a release asset is fetched by the updater's preinstall hook, which runs with a cleared environment and no token. That is the same arrangement the daemon already relies on for ONNX Runtime. Pins are commits or tags, never branches, in one file both the build and the release manifest read — a plugin whose version nobody can name is what makes a media bug unreproducible, which is exactly what the third-party debs we rejected could not answer. gst-plugins-rs is pinned at 0.15.3 rather than the 0.14.5 the reachy_mini SDK documents: 0.14.5 is the floor that matters, since the tags below it miss a webrtcsink deadlock fix between remote description and ICE handling, and both series declare a GStreamer v1_22 floor against a robot running 1.26.2. Two guards written from reading the trees rather than hoping. `gst/rockchipmpp/meson.build` ends in `if not mpp_dep.found() → subdir_done()`, so a missing librockchip-mpp-dev makes meson skip the plugin and *succeed*; pkg-config is checked first and the .so checked for after. And the Radxa debs are installed as one closure, because dpkg -i resolves nothing for direct downloads — learning that one package at a time cost three rounds on a board. Building also drops rkximage and kmssrc, the X11 and KMS sinks in the same tree, which a headless robot has no use for and which are why the prebuilt deb depends on libx11-6.

# `gstreamer1.0-rockchip1_1.14-4` is **decode-only** — measured on a Zero 3W, it provides

# 0.15.3 rather than the 0.14.5 that Pollen's reachy_mini SDK documents. 0.14.5 is the floor that

# handling, which presents as a client spinning forever on "connecting" — and 0.15.3 is simply
|
|
# newer than it. Both declare a GStreamer `v1_22` feature floor, and the robot runs 1.26.2, so
|
|
# the newer series costs nothing.
