VisionIPC frames from camerad → OMX H.264 hardware encoder → 3-min MP4
segments + SRT GPS subtitles in /data/media/0/videos/<trip>/. Manages
its own trip lifecycle (WAITING/RECORDING/IDLE_TIMEOUT) and writes
DashcamState/DashcamFrames memory params for the UI's Status window.
Honors DashcamShutdown for graceful close before power-off.
Files added:
- selfdrive/clearpilot/dashcamd.cc + SConscript
Files modified:
- selfdrive/frogpilot/screenrecorder/omx_encoder.{cc,h}: ported broken's
version, which adds encode_frame_nv12() (direct NV12 input from camerad,
alongside the existing encode_frame_rgba used by the disabled screen
recorder) and simplifies the libyuv conversion paths to NEON-only since
this device is aarch64.
- selfdrive/SConscript: register selfdrive/clearpilot/SConscript so the
dashcamd binary is part of the build.
- selfdrive/manager/process_config.py:
- camerad gating driverview → always_run so dashcamd can record the
moment ignition+drive arrives without waiting for camera startup.
- Register dashcamd as NativeProcess gated always_run.
- system/loggerd/deleter.py:
- MIN_BYTES 5 GB → 9 GB to leave headroom for dashcam footage.
- delete_oldest_video(): trip-aware cleanup. Drops entire oldest trip
dir first; if only the active trip remains, drops oldest segment
inside it; cleans up legacy flat .mp4s too.
- cleanup_log2(): keeps /data/log2 session logs under 4 GB total.
- Hooked into deleter_thread: video first when out of bytes/percent;
log2 quota check on the idle path. New code uses print(stderr) per
the no-cloudlog rule.
Verified: built clean, manager started, dashcamd in WAITING state
(DashcamState=waiting, DashcamFrames=0), camerad running, no errors.
- onroad.cc: fix screenDisplayMode reference to nvg->screenDisplayMode
(baseline had a stale reference to the variable after it moved into
AnnotatedCameraWidget). Restores the original conditional intent.
- ui/SConscript + home.cc: drop QtWebEngine include/link entirely
(no longer used by any active code).
- build.py: BUILD_ONLY env var spawns the failure TextWindow fully
detached (own session, /dev/null stdio) so build_only.sh exits and
caller can capture stderr; spinner binary update uses temp+os.replace
so a running spinner doesn't ETXTBSY the build.
- build_only.sh: tee build output to /tmp/build.log and propagate
build.py's exit code via PIPESTATUS.
Verified: build_only.sh completes cleanly, launch_openpilot.sh boots
the manager and spawns the standard process set.
Restoring the working tree to the pristine pre-Claude baseline previously
preserved at /data/clearpilot (now /data/clearpilot-baseline). The prior
modified-but-broken tree is snapshotted at /data/openpilot-broken-2026-05-03
and tagged here as pre-reset-2026-05-03 for reference.
From here, features (UI changes, dashcam, telemetry, GPS, display modes,
speed logic, standstill power saving, etc.) will be re-introduced one at
a time with proper testing.
- OMX_Init/OMX_Deinit managed per encoder instance lifecycle
- Proper error handling in constructor, encoder_open, encoder_close
- Null guards on done_out.pop() and handle in destructor
- Codec config written directly to codecpar (no codec_ctx)
- ffmpeg faststart remux on segment close
- Crash handler in dashcamd for diagnostics
- DashcamFrames param for live frame count in status window

- Reset OMX subsystem (Deinit/Init) on dashcamd startup to clear stale
encoder state from previous unclean exits
- Validate OMX output buffers before memcpy to prevent segfault
- Validate VisionBuf frame data before encoding
- Add dashcam row to status window showing recording state and disk usage

- New dashcamd: connects to camerad via VisionIPC, feeds raw NV12
frames directly to OMX H.264 encoder. Full 1928x1208 resolution,
4Mbps, 3-minute MP4 segments. Works regardless of UI state.
- Added encode_frame_nv12() to OmxEncoder — skips RGBA->NV12 conversion
- Suspends recording after 10 minutes of standstill
- Disabled old screen recorder timer in onroad.cc
- Suppress debug button alert (clpDebug event still fires for screen toggle)
- launch_openpilot.sh self-cleans other instances before starting
- Register DashcamDebug param in params.cc and manager.py
- Add dashcamd to build system (SConscript) and process_config
- Updated CLAUDE.md with all session changes
- Added GOALS.md feature roadmap

- Re-enable FrogPilot OMX screen recorder (H.264 MP4, 1440x720, 2Mbps)
- Auto-start recording when car is on, auto-stop when off
- Hide all recorder UI elements (invisible to driver)
- Add ScreenRecorderDebug param for bench testing without car
- Disable encoderd (camera .hevc files) — CAN/sensor logs still recorded
- Raise deleter free space threshold from 5GB to 9GB
- Deleter rotates oldest videos before log segments
- Add CLAUDE.md project documentation
