Context

I'm trying to build this from the source on a windows machine but can't get it to work either by installing via npm install or node-gyp rebuild --python "path-to-python" --msvs_version=2015

Your Environment

• Screencat version: 4.2.0
• RobotJS version: 0.4.5
• Node.js version: 6.9.2 32-bit
• npm version: 4.0.5
• node-gyp version: 3.4.0
• Python version: 2.7
• Visual Studio: 2015 Professional Update 3
• Operating System: Windows 7 SP1 64-bit

you can't do a screensharing session + and audio session over the same stream, but you can do two separate streams. we should add this :D hard part would be bootstrapping the second session (sdps) over the first stream

It would be cool if you could share a link like this:
http://maxogden.github.io/screencat/remote#sugar-shadow-snowball

and it would automatically connect the remote to your computer.

I started a similar project lately and then realized that there must be another screen sharing electron app. I found this one via awesome electron but it looks like it isn't maintained anymore. Latest commit Dec 2015. Am I right?

Hello friends,

I have installed screencat on my local Ubuntu 16.10 system. I have also installed robotjs and electron from the links given in guide. However, when I start it, it shows it has started, but no UI and no idea how to connect to it or show the html page.

This is what I see when I issue npm start

npm start

> [email protected] start /usr/local/lib/node_modules/screencat
> electron electron.js

(electron) ipc module is deprecated. Use require("electron").ipcMain instead.
ready

How can I connect to screencat? Thank you.

when screencat launches the first time it goes to the menu bar. it would be nice if it started open right away.

maybe 2 codes? one for watching (read only) one with screen-share (read write)

the use case in mind is 2 people want to screen-share but also want to broadcast to more people

ive read that ICE/STUN works on most routers best if you do the handshakes within 30s, so we should try and fix that to improve connectivity.

we should make it easy to go fullscreen when looking at someone elses screen

I'm following the directions in the readme for building on Windows, but I'm hitting an error on 'npm start':

This needs to go full engelbart -- add in (optional) video chat overlay screen.

btw, @maxogden @mafintosh see:

• https://www.youtube.com/watch?v=yJDv-zdhzMY (wikipedia)
• http://static.benet.ai/t/papers/cs208/30_engelbart62.pdf
• http://static.benet.ai/t/papers/cs208/31_engelbart68.pdf

I clone the repo and run npm run app and never get the screen code to share.

I don't know if has anything to do with it, but in the console I get this error:

[40713:0328/162940:INFO:CONSOLE(118)] "Uncaught Error: Module did not self-register.", source: ATOM_SHELL_ASAR.js (118)

I'm on Yosemite(v10.10.2).

right now we use trickle-less SDP swapping through a custom lobby signalling server.

it would be better to use ICE/STUN, but in general I was displeased with the state of many of the signalling servers on npm, which is the main reason I made https://github.com/maxogden/cat-lobby. if someone can recommend a simple signal lobby that can do ICE/STUN then I would be happy to swap out the backend

it would be cool to use TURN, though I need to figure out a way to measure failure metrics first before investing in higher bandwidth infra like that

this would require a webrtc -> rtmp streaming transcoder (not sure how to do that)

https://developers.google.com/youtube/v3/live/docs/liveStreams

the idea is you can use screencat to broadcast your screen + audio directly to a youtube live stream. maybe hangouts on air is possible to somehow?

Hi,

This gives error to load robotjs in mac. Has anyone faced this issue?

[Error: ./robot.js failed to load]
[Error: Module version mismatch. Expected 47, got 48.]

I have not done a lot of work with atom-shell, but would be nice to name the process differently. Related to #5 I had to hunt for which process to kill, top shows it as Atom.

Sharing a specific window or an area would be a nice capability - chromium has it as a functionality, as it uses it for chromecasting.

By initial research, I assume this happens by setting chromeMediaSource to "desktop" and chromeMediaSourceId to a value returned by chooseDesktopMedia - https://developer.chrome.com/extensions/desktopCapture.

for video, we can totally do it, but I wouldn't want it to be on by default.

also I was thinking it would be cool to save bandwidth by converting video to ascii (e.g. http://blog.nobel-joergensen.com/2011/11/12/creating-real-time-video-ascii-art-using-kickjs-and-webgl/) and sending the ascii along, rendering it in the corner of the screen. that way you can see if the other person is around, but it's low res enough that it isn't uncomfortable

What ? Where :D

Is it possible to capture and stream system sound? Example, playing a video on VLC?

Feedback like an end user is going to give. I clicked on join screen with code, and then I could not quit the app. Or maybe you are making ransomware ;)

It doesn't seem to work for me on a powerbook with the latest OS.

AppImage is a format for distributing portable software on Linux without needing superuser permissions to install the application.

It would be nice if the screencat project could provide official AppImages for Linux. electron-builder can build them for "free".

I cannot connect to the lobby
Failed to load resource: the server responded with a status of 504 (Gateway Time-out)
EventSource cannot load http://catlobby.maxogden.com/v1/salem-gracie-zoe/pings. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://maxogden.github.io' is therefore not allowed access. The response had HTTP status code 504.

Just wanted to test screencat and got the error show in the attached screenshot. Seems like the cat-lobby server is down?! Any advice? Thanks in advance!

It would be great, if you could provide a flatpak of this.

Hi,

Two questions(may be novice level):

• Where is remote-bundle.js As here ? How do you run on github.io? I think xhr are not allowed on github?

• How are the services built, like catlobby?
  var server = 'http://catlobby.maxogden.com' // var server = 'http://localhost:5005' var remoteConfigUrl = 'https://instant.io/rtcConfig'

main thing is support for translating keyboard events between operating systems and layouts via https://github.com/octalmage/robotjs (or more specifically my fork https://github.com/maxogden/robotjs/tree/keyupdown)

HI,

Is there possibility use the screen share and Key board & mouse usage after users locked his computer after screen shared?

now that I added audio chat, we should have a way to control audio gain. Not sure the cleanest way to add it to the UI now though, suggestions welcome. This can be implemented using the WebAudio API Gain Control Nodes. There are probably other interesting controls/effects we can surface as well

version 4.2.0 claims to be version 0.34.2 when selected in the Finder

Instant.io, catlobby and cors pages are 404 so can we replace them? Max can you please help us and make the app work again ?

it would be nice if the menu bar icon stayed selected while the window is open (right now it selects and unselects). it's non-obvious to users where the screen popped up from.

in particular, at least make it so on the landing page image, so that users know what instantly icon they should expect to appear after installing.

hello,friend
I get function getRemoteConfig() ,is this get remote webrtc config(ice/stun/turn) ,how I modify var remoteConfigUrl to my iceserver
I use coturn in my server , and how to use my coturn server
Thank u and God bless u

I wanna add a password feature to invites. Currently anyone with your invite code can control your computer.

when you create an invite it should ask if you wanna password protect it

if you choose yes, you have to enter a password.

we then use the password to AES encrypt the SDP before it gets uploaded to the lobby

If you don't specify a password you should a clear warning like 'Anyone with this room name will be able to join and see your screen'

copy paste / keyboard shortcuts from the webpage weren't working. not sure if bug or not intended.

The UI is pretty barebones. If anyone wants to PR any UI improvements I would happily merge. Just ask before spending time integrating any large frameworks/dependencies

this is so the user can copy/paste the ScreenCat app directly into the Applications folder

right now we only support single clicking. improving this is dependent upon what we can get into https://github.com/octalmage/robotjs. My current fork is here https://github.com/maxogden/robotjs/tree/keyupdown. I intended to PR it at some point

I would suggest renaming the button 'Join Screen with Code' to just 'Join Screen'. Not sure who the intended audience is for the app, but I think it's more terse.

I was looking at the mdn's documentation and realized that mozInnerScreenX was what we were looking for the other night.

unfortunately, doesn't look implemented by other vendors right now.

So i guess mouse events' hack probably still work well. cc. @timoxley

it would be awesome to be able to share your screen with multiple controllers. I'd imagine the major limitation is upload bandwidth on the host end

getting this error where the shareable link is supposed to be.
Error! getaddrinfo ENOTFOUND catlobby.maxogden.com catlobby.maxogden.com:80

yout code include:
first:
var server = 'http://catlobby.maxogden.com';
var remoteConfigUrl = 'https://instant.io/rtcConfig';
if (process.browser) remoteConfigUrl = 'http://cors.maxogden.com/' + remoteConfigUrl;
function verifyRoom (room, cb) {

second:
// ensure room is still open
nets({method: 'POST', uri: server + '/v1/' + room + '/pong', json: {ready: true}}, function response (err, resp, data) {
if (err){
console.log('connect server error: ', err);
return cb(err)
}

  if (resp.statusCode !== 200) return cb(new Error('Invalid or expired invite code'))
  cb()
})

}
thrid:
// get remote webrtc config (ice/stun/turn)
function getRemoteConfig (cb) {
nets({url: remoteConfigUrl, json: true}, function gotConfig (err, resp, config) {
if (err || resp.statusCode > 299) config = undefined // ignore errors
cb(null, config)
})
}
fourth：
// get remote webrtc config (ice/stun/turn)
function getRemoteConfig (cb) {
nets({url: remoteConfigUrl, json: true}, function gotConfig (err, resp, config) {
if (err || resp.statusCode > 299) config = undefined // ignore errors
cb(null, config)
})
}

I think that this two url is to deal code, but I think your server is down , I want to ask you what logic about your two request( uri: server + '/v1/' + room + '/pong' and url: remoteConfigUrl,), and the getRemoteConfig function return the data is or not json format? please give me an example of the config object

I want to create server about like your 'http://catlobby.maxogden.com' to deal code logic , but I do not how to create and the server Background logic and field of your data

the cat should turn red when you are sharing your screen

this can be done with the atom-shell tray/icon APIs

when I run "npm start", It's stuck-- it just says 'ready' in console. What should I do to make it start？please give some advice, thanks.

Hi i'm new.
How can I build this for windows?? is it support windows or not? :)

Error message is bellow.

Kanny@DESKTOP-O2HSVSO ~/screencat (master)

I am working on a project similar to this, I would like to know how many people are currently interested in the project so I can share it with all of you. The project is not a fork, and I currently have it advanced enough to help me improve it.
thank you all guys

I don't seem to be able to copy paste codes, or cmd-a to select the text in the text input.

Would be cool if you could advertise/see/connect to others on the same network via mdns like in mafintosh/airpaste
