In-app messages are targeted notifications sent to customers/ users while they are active on the website or mobile application. They are a very effective way to engage customers as they are already within the application looking for specific information. In-app chat applications help connect better with the users and improve user retention as they are timely and targeted.

Screensharing from FFmpeg to WebRTC
In the comment sections of our articles about our server there are often users who say: "Why would you jump through so many hoops, when you can do the same with a single line of code in FFmpeg!?"
Practical uses of WebRTC Canvas streaming
In this article we will once again return to the tired topic of webinars and webinar hosting tools. And no, we're not about to code a whole new system for webinar hosting – there are already plenty of those. Instead, we will talk about connecting drawing software to the webinar, so that you could manually draw and broadcast the process.
WebRTC in Docker. Struggling for resources
A few weeks ago we wrote an article about Docker and WebRTC servers and talked about the intricacies of launching containers. Our readers (rightly) questioned whether Docker was a suitable tool for production, for the following reasons:
WebRTC screen-sharing with authorization and other benefits
The popularity of online education is increasing every month. And since there is an increase in popularity, there is an increase in competition and an improvement in quality: many authors of online schools realized that nowadays it's not enough to just make something mediocre using the frontal camera of the iPhone 4. You need to work on the quality of the picture, sound, presentation of material, etc. Not only did the pandemic prove that you can teach salsa and even crochet online, so it also gave an excellent push to improve the materials taught + diversity in the labor market. Moms on maternity leave can rejoice - now you can truly earn a hundred thousand million per second, sitting at home.
How to make a multipoint WebRTC conference MCU with recording and screen-sharing in the browser
During the lockdown, which is now weakening, then becoming more active with a vengeance, a huge number of new professions have appeared. Proficients in creating involving Instagram Stories, course producers, e-learning specialists and other unknown-before-creatures - all of them have mastered a new job that gave them the holy bread in the pandemic. Once you hire a creator of involving Instagram Stories (and let's all hope this person was teached by a professional, not a snake oil salesman), your business grows just with adding some creativity in advertising that will take the heart of even the most fastidious customer. Same works with e-learning specialists: you recruit them and they do all the important tasks from writing articles that will also help in promoting your classes to arranging lessons on your Coursera course. A complete flight of imagination: if it seems to you that some jobs don't exist, then you just don't spend enough time online. In general, online work has become popularized as never and now hardly anyone will say: "He is engaged in some kind of garbage - he makes TikToks but it would be better for him to toil at the factory!". In total, online work has become popularized as never and now hardly anyone will say: "He is engaged in some kind of garbage - he makes TikToks, but it would be better for him to toil at the factory!".
Google Cloud Platform for WebRTC CDN with Balancing and Autoscaling
In the previous article we refreshed our memory of WebRTC CDN and the ways this technology helps to minimize latency for WebRTC streams. We also discussed why load balancing and autoscaling wouldn't be amiss in CDNs. Here are the main points from the article:
Automatize it, or Docker container delivery for WebRTC
The vast majority of IT specialists in various fields strive to perform manually as few actions as possible. I won't be afraid of the loud words: what can be automatized, must be automatized!
Let's imagine a situation: you need to deploy a lot of servers of the same type and do it quickly. Quickly deploy, quickly undeploy. For example, to deploy test rigs for developers. When development is carried out in parallel, you may need to separate the developers, so they don't impede each other and possible errors of one of them don't block the work of the others.
There may be several ways to solve this problem:
Streaming multiple RTSP IP cameras on YouTube and/or Facebook
As you know, YouTube doesn't have a feature for capturing an RTSP stream, but we would like to change this and help YouTube to make their viewers happy.

Simple and free video conferencing
Looking for a Zoom alternative?Here are the best suggestions for videoconferencing apps
As much of the world works from home amid COVID-19 lockdowns and ‘shelter in place’ restrictions, video call and conferencing apps have experienced a significant surge in user numbers. From top business executives to scientists and government officials, the employed across industries and roles have moved operations online and onto video conferencing apps such as Zoom.
The dark side of this change is that video calls have also become a playground for phishermen and ‘Zoombombers’. This development was recently experienced by Zoom users, who took to the internet to allege that Zoom vulnerability windows were compromised and ‘Zoom is not safe to use’.
In March alone, the number of Zoom users saw a whopping 535% increase, with its iPhone app being the most downloaded for weeks at a stretch. However, reports of security disasters and Zoom privacy issues saw the brand’s credibility snowballing at an alarming pace. Despite the company CEO stepping up to the plate and ramping up privacy measures, professionals continue to debate on whether the Zoom privacy and security issues, that risked data of millions, can be quickly resolved.
How Video Conferencing Solutions Plays a Major Role in Official Business Meetings?
Video call and video conference software allows online messages for voice meetings, video conferences, and discussion groups, which includes features such as converse, screen division, and video recording.
Review of WCS 5.2 — WebRTC Server for Webcast and Webcam Developers
Alice is an experienced full stack developer, who is capable of writing a SAAS project framework on her favorite framework using php in a week. As for frontend, she prefers Vue.js.
A client contacts you via Telegram, asking you to develop website that will be the meeting place for the employer and the employee to conduct an in-person interview. In-person means face-to-face, a direct video contact in real time with video and voice. «Why not use Skype?» some may ask. It just so happened that serious projects – and each startup undoubtedly considers itself a serious project – are trying to offer an internal communications service for a variety of reasons, including:
WebRTC streaming in and around virtual reality
Virtual reality is on the rise these days. The equipment that was previously the exclusive preserve of crazy scientists geeks with big money from the Ministry of Defense back in the The Lawnmower Man days, is currently affordable for ordinary people; those whose pockets are empty, can assemble a VR headset from cardboard and a smartphone according to many recipes.
The first viewer issue, or the difficulties of converting WebRTC video streams to HLS
George shut his laptop and rubbed his sleep-deprived red eyes. "Customers continue to complain about stream freezing; the new fix package did not help at all! What do I do with this (censored) HLS?" he said.
The browser is not only hypertext, but also a streamer
Browsers have had players for a long time, but the story is different with the video encoder and streaming. Now, in almost any browser of the latest version, we can find modules for encoding, streaming, decoding, and playback. These functions are available through the JavaScript API, and the implementation is called Web Real Time Communications or WebRTC. This library built into browsers can do quite a lot: capture video from a built-in, virtual or USB camera, compress it with H.264, VP8, and VP9 codecs, and send it to the network via SRTP protocol; i.e., it functions as a software streamer video encoder. As a result, we see a browser that has something similar to ffmpeg or gstreamer, compresses video well, streams on RTP, and plays video streams.
Channel quality indicator for server WebRTC over TCP
Publish and Play
There exist two main functions of WebRTC operation on the server side in the field of streaming video: publishing and playing. In the case of publishing, the video stream is captured from the web camera and moves from the browser to the server. In the case of playing, the stream moves in the opposite direction, from the server to the browser, is decoded and played in the browser’s HTML5 <video>
element on the device’s screen.
How to cook RTSP on your website in 2020, or why the boars will not have a chance to run away
RTSP is a simple signaling protocol which they cannot replace with anything for many years already, and it has to be admitted that they don't try really hard.
For example, we have an IP camera that supports RTSP. Anyone who has ever tested the traffic with a Sharkwire cable will tell you that first there comes DESCRIBE, then PLAY, and then the traffic begins to pour directly via RTP or wrapped in the TCP channel for instance.
Dynamic CDN for Low Latency WebRTC Streaming with Stream Access Control
In the first part, we have deployed a simple dynamic CDN for broadcasting WebRTC streams to two continents and have proved on the example of a countdown timer that the latency in this type of CDN is actually low.
In the second part, we have incorporated dedicated servers into the CDN for performing the task of transcoding in order to provide good broadcast quality to our viewers based on the devices they use and the channel quality. In this manner, all published streams in our CDN are available to all the viewers.
Now, assume that a company is starting to introduce its monetization strategy where a number of streams should be available for free and the rest on a subscription basis. Or, for example, webinars for in-house staff training are broadcasted simultaneously, but each subsidiary has a separate stream, and disclosing the sales techniques used in Southeast Asia to the managers from CIS countries is undesirable.
