player: NV12 zero-copy SDL upload path for Rockchip MPP hardware decode
...
- _Frame: add pixel_format ('BGRA'|'NV12'), uv_pixels, uv_pitch fields
- _create_appsink: accept NV12 caps when R36S_HW_DECODE=1 (NV12;BGRA fallback)
- render(): choose SDL_PIXELFORMAT_NV12 texture + SDL_UpdateNVTexture for NV12
frames, avoiding any software colourspace conversion on the CPU
- _on_new_sample: detect format via VideoInfo.finfo.name, extract Y+UV planes
separately from NV12 GStreamer buffers
- _destroy_texture: reset _texture_format to 'BGRA'
- deploy/arkos/MatHacks.sh: set R36S_HW_DECODE=1 to activate the path
- tests/test_player.py: add finfo mock, pixel_format to SimpleNamespace frame

deploy: bundle pre-built MPP libs for RK3326, update setup script and status
...
- deploy/arkos/mpp-libs/: add librockchip_mpp.so*, librockchip_vpu.so*,
libgstrockchipmpp.so — built from source via Docker QEMU (arm64v8/ubuntu:focal)
using rockchip-linux/mpp + JeffyCN/mirrors@gstreamer-rockchip (-Drga=disabled)
- deploy/arkos/setup_hw_decode.sh: detect mpp-libs/ subdir and install from it
automatically, no network required; apt fallback retained
- deploy/arkos/mpp-libs/README.md: document origin, target SoC, install steps
- tests/test_video_playback_device.py: on-device GStreamer diagnostic script
- docs/development-status.md: mark MPP HW decode deployed, mppvideodec verified
Verified on physical R36S: mppvideodec found by GStreamer registry with
GST_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/gstreamer-1.0

deploy: add run.sh launch wrapper with GST_PLUGIN_PATH+LD_PRELOAD for R36S
...
On linux-aarch64 the conda gst-libav package has an unfixable ABI mismatch
(libdav1d.so.6 missing, libicuuc.so.78 via libxml2-16). Fix: use system
gstreamer1.0-libav installed via apt with GST_PLUGIN_PATH, and preload
system libgomp.so.1 to avoid static TLS block errors when dlopen loads
libgstlibav.so. avdec_h264 and avdec_aac now register correctly on device.
These vars are stored in conda activate.d/gst-env.sh and in deploy/run.sh.
