Status

Completed (2026-04-11)

Disabled comma training data video encoding (encoderd) — CAN/sensor logs still recorded
Re-enabled FrogPilot OMX screen recorder (H.264 MP4, 1440x720, 2Mbps, hardware encoded)
Auto-start/stop recording tied to car ignition (scene.started)
ScreenRecorderDebug param for bench testing without car connected
Hidden all recorder UI elements — invisible to driver
Videos saved to /data/media/0/videos/YYYYMMDD-HHMMSS.mp4, 3-minute segments
Deleter updated: 9 GB free space threshold, rotates oldest videos first
Cleaned up offroad UI: replaced stock home screen with grid launcher (Settings + Dashcam buttons)

Next: Dashcam Footage Viewer

Build a native Qt widget accessible from the offroad home screen "Dashcam" button.

Requirements:

List MP4 files from /data/media/0/videos/ sorted newest first
Tap a file to play it back using Qt Multimedia (QMediaPlayer + QVideoWidget)
Only accessible when offroad (car in park or off)
Back button to return to offroad home
No rotation hacks needed — native Qt widget in existing UI tree handles rotation correctly

Architecture:

New widget class (e.g. DashcamViewer) added to selfdrive/ui/qt/
Wire into HomeWindow's QStackedLayout alongside home, onroad, ready, driver_view
Dashcam button in OffroadHome switches slayout to the viewer
Viewer has a file list view and a playback view (sub-stacked layout)
Back button returns to OffroadHome
Build: add to qt_src list in selfdrive/ui/SConscript, link Qt5Multimedia

Previous webview attempts (abandoned):

Brian tried QWebEngineView for browser-based playback but the WebEngine subprocess renders independently of Qt's widget tree
Screen rotation (view.rotate(90), Wayland wl_surface_set_buffer_transform) did not work for WebEngine content
Native Qt widget approach avoids this problem entirely
