If your camera generates empty .mp4 files when recording, you might need to update its audio codec by passing in one usable by your camera (e.g., aac) in the Recorder's constructor. For example:

1  var rec = new Recorder({
2    url: 'rtsp://192.168.1.12:8554/unicast',
3        timeLimit: 60, // time in seconds for each segmented video file
4        folder: '/Users/sahilchaddha/Sahil/Projects/Github/node-rtsp-recorder/videos',
5        name: 'cam1',
6        audioCodec: 'aac'
7  })

Capturing Image

12    })

Managing Media Directory

1    const FileHandler = require('../src/helpers/fileHandler')
2    const fh = new FileHandler()
3    // RETURNS DIRECTORY SIZE
4    fh.getDirectorySize('/Users/sahilchaddha/Sahil/Projects/Github/node-rtsp-recorder/videos/', (err, value) => {
5    if (err) {
6        console.log('Error Occured')
7        console.log(err)
8        return true
9    }
10    console.log('Folder Size is ' + value)
11    })
12    // REMOVES ALL MEDIA FILES
13    fh.removeDirectory('/Users/sahilchaddha/Sahil/Projects/Github/node-rtsp-recorder/videos/*', () => {
14    console.log('Done')
15    })

Setting custom filename formats

1    const Recorder = require('node-rtsp-recorder').Recorder
2
3    var rec = new Recorder({
4        url: 'rtsp://192.168.1.12:8554/unicast',
5        timeLimit: 60, // time in seconds for each segmented video file

7        name: 'cam1',
8        directoryPathFormat: 'MMM-D-YYYY',
9        fileNameFormat: 'M-D-h-mm-ss',
10    })
11    // Default directoryPathFormat : MMM-Do-YY
12    // Default fileNameFormat : YYYY-M-D-h-mm-ss
13    // Refer to https://momentjscom.readthedocs.io/en/latest/moment/04-displaying/01-format/ for custom formats.
