  • Web overlay in GStreamer with WPEWebKit

    After a year or two of hiatus I attended the GStreamer conference which happened in beautiful Edinburgh. It was great to meet the friends from the community again and learn about what’s going on in the multimedia world. The quality of the talks was great, the videos are published online as usual in Ubicast. I delivered a talk about the Multimedia support in WPEWebKit, you can watch it there and the slides are also available.

    One of the many interesting presentations was about GStreamer for cloud-based live video. Usually anything with the word cloud would tend to draw my attention away but for some reason I attended this presentation, and didn’t regret it! The last demo presented by the BBC folks was about overlaying Web content on native video streams. It’s an interesting use-case for live TV broadcasting for instance. A web page provides dynamic notifications popping up and down, the web page is rendered with a transparent background and blended over the live video stream. The BBC folks implemented a GStreamer source element relying on CEF for their Brave project.

  • GStreamer’s playbin3 overview for application developers

    Multimedia applications based on GStreamer usually handle playback with the playbin element. I recently added support for playbin3 in WebKit. This post aims to document the changes needed on application side to support this new generation flavour of playbin.

    So, first of, why is it named playbin3 anyway? The GStreamer 0.10.x series had a playbin element but a first rewrite (playbin2) made it obsolete in the GStreamer 1.x series. So playbin2 was renamed to playbin. That’s why a second rewrite is nicknamed playbin3, I suppose Smile

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
