CosyDVR

Free and open source car digital video recorder (DVR). Application can continuosely record video, splitting it on fragments with user-defined duration. It can be used as car blackbox. Ascetic but cosy interface doesn't need much attention from user. Just start it and forget until trip ends. Autostart recording on program start is an option. Application works in background when other sofware e.g. navigation is in use. It continues recording even with screen locked including audio. Night mode lightens image during night operation. Timelapse mode can save sdcard space for slow or no-motion periods. Different focus modes and manual flash switching complete feature set. GPS and time data are gathered and recorded in subtitles or gpx track files. No internal viewer provided (as everyone has much more powerful videoplayers). No ads. Tiny size. You will be satisfied.
