Enhancements to the read-only version 0.1

[DBaluxa]

• Saving RTSP stream to the SD via ffmpeg, and removing old video files when SD is almost full
• Securely forwarding RTSP stream to given host via SSH port forwarding. Usefull when integrating a camera into a video surveillance sytem (e.g. zoneminder) outside the local network. Implemented watchdog process, which rebuilds stalled SSH connection after a network error.
• Hardening the system - Telnet connection disabled, FTP and SSH connections asks for password (password should be added both to /etc/passwd and /etc/shadow - password change not included in the change)

Hi paus56,

There is no such script, which kills the ffmpeg executable, so my guess is that ffmpeg has been killed by the kernel because of resource problems (e.g. not enough memory). Try starting ffmpeg.sh manually, while monitoring the system resources.
Changing ffmpeg's logging level ("-v warning") in ffmpeg.sh to info/debug level may also help finding the problem.

BR,
DBaluxa

You can add a cURL to your package, to send video files to FTP ?
