Building an AI agent for transcribing and summarizing audio calls

Header image: a microphone turning into text inside an audio call

With the world being flooded with all kinds of agents, bots, and AI services, let's keep things grounded and code something tangible in a few simple steps. Let's build an AI agent that helps people in an audio call. Our agent will:

  1. Store the full transcript of the meeting in a text file.
  2. Send live captions to everyone in the call.
  3. When someone joins late, send them a private summary of what they missed.

We'll be using OpenVidu as our media server, and LiveKit Agents Python framework to build our agent. These tools handle all the hard parts of real-time audio transport, so we can focus on our agent features.

How DynDevice Built Virtual Classrooms Into Its LMS with OpenVidu

DynDevice and OpenVidu customer success story DynDevice and OpenVidu customer success story

What do you do when your product depends on video meetings that happen somewhere else? For years, the trainers using DynDevice, the corporate eLearning platform built by Mega Italia Media, had to send their learners out of the LMS and into Zoom, Meet, Teams, WebEx or GoToWebinar links to run a live class. It worked — and it fragmented the learning experience every single day.

This post kicks off our series on how engineering teams solve real WebRTC and infrastructure challenges. We interviewed Matteo Resconi, IT & Development Area Manager at Mega Italia Media, about the journey from juggling five external meeting tools to one-click virtual classrooms built into their own platform: what they evaluated, why they didn't build on raw WebRTC, and what changed for their team and their users.

Building a video-enabled CRM with an AI agent and OpenVidu Meet

What does it take today to go from an empty folder to a working business app with video meetings embedded in it? As it turns out: one AI coding agent, one OpenVidu Meet deployment, and seven prompts.

We recently ran this experiment: build a small CRM — clients, support issues, scheduled meetings — entirely with an AI agent, then ask the agent to integrate OpenVidu Meet so that meetings happen inside the app instead of in an external tool. Every prompt we typed is preserved in the repository, so this post is a faithful, reproducible walkthrough of the whole journey — including the parts where reality pushed back.

Managing Permissions in Video Conferencing Apps: 3 Access Models

Three access models for video conferencing permissions

Everyone benchmarks video conferencing on the things you can see: resolution, latency, how many people fit in a grid. But the failures that actually hurt in production are rarely about a dropped frame — they're about the wrong person joining a room they shouldn't be in, or a private recording ending up somewhere public. Permissions are the invisible half of a video app, and they're the half most teams underestimate until something goes wrong.

OpenVidu 3.8.0 is now available

OpenVidu 3.8.0 brings a major step forward for both OpenVidu Platform and OpenVidu Meet.

On the OpenVidu Platform side, the standout change is a complete mediasoup overhaul: RTX, DTX, AV1/VP9/H264 codecs and SVC are now fully supported, bringing mediasoup on par with Pion in terms of features while delivering a 2x performance boost. This release also tightens TURN security and improves the robustness of deployments across all supported clouds.

On the OpenVidu Meet side, this release introduces real user accounts with role-based access and fine-grained, per-person room permissions, turning the previous "share a link" model into a complete access control system. It also comes with a redesigned application, now fully translated into 10 languages, and a range of improvements to the in-meeting experience.

We deployed the same video platform on five clouds and timed it: 5 minutes to 20, and the slow ones are slow for a reason

Mean time to a working deployment, by cloud and topology Mean time to a working deployment, by cloud and topology

"How long does it take to deploy?" sounds like a trivia question until you're the one watching a progress bar, wondering whether it's stuck. So we stopped guessing and measured it.

We built a tool, ov-cloud-tester, that deploys the same self-hosted WebRTC video stack on all five major clouds — AWS, Azure, Google Cloud, Oracle Cloud and DigitalOcean — in three topologies (single node, elastic, and high-availability), tears it down cleanly, and times the whole thing. We ran it many times per cloud and looked at both the averages and every individual run. The headline: standing up a working deployment ranges from about 5 minutes to 20, DigitalOcean is consistently the fastest and Oracle the heaviest — and the why, plus which clouds are actually predictable, turns out to be more interesting than the ranking.

Host Your Own Secure Video Calls at Home: A Private Server for Family and Friends

A secure family video call running on your own home server

We're all used to reaching for a third-party app to call friends and family: Google Meet, Zoom, Microsoft Teams, etc. Almost nobody wants to complicate their life by running their own server, and if you mention "spinning up a WebRTC media server" to an experienced sysadmin, they'll probably put their head in their hands thinking about how complicated it must be.

In reality, it's much easier than you might think. At OpenVidu we've worked hard to make a self-hosted video conferencing service as easy to install and run as possible, and hosting it yourself comes with some genuine advantages. It's completely free, there are no 40-minute timers or participant limits, your guests join straight from a browser with no account and no app, and every call stays on hardware that lives in your own home.

With a tiny computer like a Raspberry Pi, an old laptop or a mini-PC, you can have your own private video conferencing server running in a matter of minutes. This guide walks you through it in three simple steps using OpenVidu Meet.

5 conversational AI app ideas you can build this weekend

Conversational AI app ideas for 2026 — real-time voice and vision agents you can build this weekend Conversational AI app ideas for 2026 — real-time voice and vision agents you can build this weekend

AI is moving faster than any of us can comfortably keep up with. Every week brings a new model, a new demo, or a viral thread claiming that everything has changed again. Keeping up feels almost impossible.

As AI becomes mainstream, the noise grows even louder. Social feeds are packed with promises of overnight success: build a startup with vibe coding, replace entire teams with a handful of prompts, make money while you sleep.

This post isn't another one of those promises.

Instead, you'll find five conversational AI app ideas you can realistically build over a weekend. Some are practical, some are a little unconventional, but all of them will teach you something valuable about how modern AI systems actually work.

More importantly, these aren't just toy projects. They can help you develop real AI skills, build a portfolio, test business ideas, and maybe even create something people are willing to pay for.

Choosing the right level of abstraction in self-hosted WebRTC solutions in 2026: OpenVidu Meet vs OpenVidu Platform

OpenVidu Meet vs OpenVidu Platform

In this blog post we explore how different levels of abstraction are needed in the WebRTC arena, and which choices do you have when using the OpenVidu WebRTC ecosystem.

Why Abstraction Matters

People are diverse, and that’s what makes life interesting. In the world of real-time communications (RTC), diversity means that different users require entirely different levels of abstraction to get the job done, from a "batteries included" scalable meeting application, to an extremely customizable media processing pipeline with access to low-level media SDKs and APIs.
