    In this tutorial, we will show you how to install FFmpeg on Manjaro 20. For those of you who didn’t know, FFmpeg is open-source software (also a command-line tool) for transcoding multimedia files. It contains a set of shared audio and video libraries such as libavcodec, libavformat, and libavutil. With FFmpeg, you can convert between various video and audio formats, set sample rates, capture streaming audio or video, and resize videos.

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 through the step-by-step installation of FFmpeg on a Manjaro 20 (Nibia).

  • ARM in the Datacenter

    ARM processors have seen unprecedented growth in the last three years and are now being used in everything from smart watches to Apple's new M1 desktop and laptop systems, but there is one sector where they have yet to take hold: the enterprise market. For years, many of the largest cloud providers have designed computers around ARM chips, and in December 2020, Microsoft said it was joining the fray by designing its own ARM-based chips for Azure and Surface PCs. Now we are seeing technology based on ARM chips float down from the cloud providers and rise up from the consumer market and start to take hold in the datacenter.

  • Hacked Codecov uploading script leaked creds for two months

    Scores of projects potentially affected by supply chain attack. A malicious alteration to a shell script lay undetected since January this year at software testing coverage report provider Codecov, sparking fears of another significant supply chain attack. Forensic analysis shows that an unknown threat actor exploited an error in Codecov's Docker container image creation process, and gained access to the credential that allowed the modification to the company's Bash Uploader script. Codecov said a Google Cloud Storage key was accessed starting January 31 this year, and not secured until April 1 US time. The script is normally used to upload coverage reports to Codecov, but it was altered to transmit the UNIX shell environment, which can be used to store variables. [...] The company said it has rotated all credentials, including the key that was captured by the attackers, and set up monitoring and auditing to ensure that the Bash Uploader cannot be compromised like this again.
