Installing Windows drivers from CAB files:

After extracting the archive and navigating to the extracted directory in the terminal, do:

for /f %i in ('dir /b /s *.inf') do pnputil.exe -i -a %i

And that will install all drivers in the CAB file.

Build FFmpeg with Intel's QSV enablement on an Intel-based validation test-bed:

Build platform: Ubuntu 18.04LTS

Ensure the platform is up to date:

sudo apt update && sudo apt -y upgrade && sudo apt -y dist-upgrade

Install baseline dependencies first (inclusive of OpenCL headers+)

xargs: A brief primer

If you’ve spent any amount of time at a Unix command line you’ve probably used xargs. In case you haven’t, xargs is a command used to execute commands based on arguments from standard input.

Common use cases:

These who use xargs often use it in combination with find in order to do something with the list of files returned by find.

On its' own, find is a very powerful command and it has built in flags such as -exec and -delete that you can often use instead of piping to xargs. With it's simplicity, xargs tends to find more usage than find on its' own.

Low-Latency Live Streaming for your Desktop using ffmpeg and netcat:

Preamble:

In this post I will explore how to stream a video and audio capture from one computer to another using ffmpeg and netcat, with a latency below 100ms, which is good enough for presentations and general purpose remote display tasks on a local network.

The problem:

Streaming low-latency live content is quite hard, because most software-based video codecs are designed to achieve the best compression and not best latency. This makes sense, because most movies are encoded once and decoded often, so it is a good trade-off to use more time for the encoding than the decoding.
