- 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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
