Matteo Benedetto	6e15fcab5a	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	2 weeks ago
Matteo Benedetto	d79bc3e16f	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	2 weeks ago
Matteo Benedetto	ddbe31dc02	player: probe Rockchip MPP/V4L2 HW decoders at pipeline init, add setup_hw_decode.sh	2 weeks ago
Matteo Benedetto	527e63a769	deploy: add arkos/MatHacks.sh launcher with system GST_PLUGIN_PATH+LD_PRELOAD	2 weeks ago
Matteo Benedetto	4b4c90fb0c	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.	2 weeks ago
