RTSP Video Recorder - Node.JS

This script is designed to record a video stream from an RTSP source and save the recordings to the specified directory. It uses the fluent-ffmpeg library to handle the RTSP stream and create video files in MKV format.

Features

• Continuous Recording: The script continuously records the video stream and starts a new recording when the previous one ends.

• File Naming: Recordings are named based on the start time, with the filename format hour-minute-second.mkv.

• Automatic Deletion: Monitors the available disk space, and if it exceeds the defined threshold, it deletes the oldest recordings to free up space.

Configuration

To use the script, create a config.json file with the following parameters (based on config.json.example file):

• rtspUrl: The RTSP stream URL.
• recordingsDirectory: The base directory where recordings are saved.
• diskSpaceThresholdMb: The maximum size of the recording directory in megabytes. After the directory exceeds this size, the script will delete the oldest recordings to free up space.
• segmentTimeSeconds: The duration of each recording segment in seconds.
• timeZone: The time zone used to name the recordings (list of time zones: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).

Example config.json:

{
    "rtspUrl": "rtsp://admin:passwd@192.168.1.12/h264/main/av_stream",
    "recordingsDirectory": "recordings",
    "diskSpaceThresholdMb": 10000,
    "segmentTimeSeconds": 60,
    "timeZone": "Europe/Warsaw"
}
