How do I record videos through this?

Hi, I just wondering, why I cant install this magnificent plugin locally?
but have to do it globally. any clues to do it manually?

The Lodash library has been found to be vulnerable to Prototype Pollution attack.
npm advises an update to the latest library version.

Do you think it will require a lot of effort?

I tried running 'npm audit fix' but apparently the patch causes breaking changes in mjpeg-camera code.

I use cs command in zsh

cs http://140.120.200.61/mjpg/video.mjpg?camera=1 -n "Spring Grove" -p 12345

Result says

: No such file or directory

Please tell me how to fix it, thanks!

[root@cctv]# cs -l http://10.0.0.200:8008 -n "cam"
=== cam camera server listening on 8080 ===

after close browser:

/usr/lib/node_modules/mjpeg-camera/cs:50
      camera.unpipe(ws);
             ^

TypeError: camera.unpipe is not a function

[root@cctv]# node -v v4.1.1

Like in title.
Tested on Win7 x64, MAC OS - same behaviour for both.

Node 5.0.0
Npm 3.3.6

No issues when installing.

Steps to reproduce:
npm install mjpeg-camera -g
cs -l http://10.53.2.43/ -p 12345
http://10.53.2.43:12345/

hiii,

i try mjpeg-camera in windows, it work well.

but not work in linux.

i use node v10.24.1 may be need upper version??

The camera.getScreenshot example code doesn't seem to be working correctly. It correctly saves a frame into the camera-screenshot.jpg file, but it "hangs" until the following error is thrown:

TypeError: Cannot call method 'abort' of null
    at Camera.stop (/mjpeg-camera-example/node_modules/mjpeg-camera/mjpeg-camera.js:97:19)
    at Camera.<anonymous> (/mjpeg-camera-example/node_modules/mjpeg-camera/mjpeg-camera.js:119:10)
    at Timer.listOnTimeout [as ontimeout] (timers.js:112:15)

Since the Camera.prototype.stopmethod is setting the connection to null after aborting it, it seems to me that two consecutive stop calls would cause the error, most likely caused by the camera.getScreenshot call followed by the keepalive timer call.

My use case allows me to "fix" the stop call by checking if the connection is null before aborting, but this doesn't seem to be the proper fix (or at least not enough to fix it), since the same example code will hang forever (i.e., no error is thrown but the program never quits).

Thank you for mjpeg-camera by the way, I was looking for a module capable of grabbing a single MJPEG frame and this was exactly it.

I have an error importing this module and pg using Node 10.x
an example is:

const pg_1 = require("pg");
var MjpegCamera = require('mjpeg-camera');

async function getNow() {
let pg = new pg_1.Pool({
user: 'userDB',
database: 'DB',
password: 'passDB',
port: 5432,
host: 'localhost',
max: 15,
idleTimeoutMillis: 3000,
});
let strsql = "SELECT NOW() as now;";
console.log('query:' + strsql);
console.log(pg);
return await pg.query(strsql);
}

getNow();

using getScreenshot fuction, i have a problem when the camera breaks the connection. In this case, the getScreenshot fuction never gives a callback or error.

thanks

Hi,

My goal is to display in a Reactjs web app the images that my camera is streaming as MJPEG (10 per second)

Also I want to take a picture everytime I press a button.

I have the IP, username, password and url where my camera is streaming.

Am I supposed to run this library on Express backend?

I have tried it but I'm not seeing that the file is writed on /frames or /motion

Sometimes when I try to snapshot I get the next error:

videostream.on('data', this.onFrame.bind(this));
^
TypeError: Cannot read properties of undefined (reading 'on')
at Camera.start (C:\Users\100032595\Documents\GitHub\welcomi_localweb\welcomi_localweb\backend\node_modules\mjpeg->camera\mjpeg-camera.js:50:15)

Is a Hikvision camera and I followed the next doc to get the MJPEG stream:
HIKVISION

When camera.stop() is called and the connection is aborted then keepalive is called by this line:
this.connection.on('error', this.keepalive.bind(this));
and so when stop() is called again in keepalive() it tries to abort the connection that has already been aborted and set to null
resulting in error: TypeError: Cannot read properties of null (reading 'abort')

Using Node v16.14.2
