Last April I rented a large virtual machine in the Amazon Web Services cloud to run some AV1 benchmarks. They test the aom, SVT-AV1 and rav1e AV1 encoders against the x264 H.264/AVC encoder. The versions used are very recent development versions, pulled directly from source code repositories. Benchmark information and results follow !
The AV1 video codec is a modern video codec that represents both a technical improvement over its predecessors VP9 and HEVC (H.265) and a major improvement over MPEG's licensing and royalty model. Development on AV1 is far from finished, though...

The C language was created shortly after the Unix operating system in the 1970's, so that the new operating system could be written in a simple and efficient programming language, instead of assembly. Portability soon became a motivation too: to be able to run Unix and applications in heterogeneous systems caused the operating system and the C programming language to have a profound and long lasting impact on computer systems. Simplicity, efficiency and portability, built into the language and transformed into programming philosophy, came with a price...

This tutorial will guide you through writing the "Hello World" program in the C programming language. You'll use Unix-style terminal emulators and command-line tools to execute commands, Linux-style package managers to install programs and libraries, the GNU nano text editor to write C code, the meson build system to build executable programs and the Gtk+ library to write portable, cross-platform graphical programs.
Instructions for three operating systems are provided: macOS, Ubuntu Linux and Windows...
