A number of GNOME modules are switching to meson for 3.26. I myself was an early adopter for this: recipes has had meson build support since the beginning of the year, and after the 1.0 release, I’ve dropped autotools support on the master branch.
autotools are of course very familiar to most of us, and we know how to get most things done there. But it often isn’t pretty, and using meson feels like a breath of fresh air. Others have been praising meson for its simplicity, ease of use and speed, so I am not going repeat that here.
GStreamer 1.12.0 will soon be released as the latest version of this widely-used, open-source multimedia framework.
GStreamer 1.12 is bringing waylandsink DMA-BUF importation support so zero-copy multimedia playback will now work under Wayland. GStreamer 1.12 is also bringing Fraunhofer FDK AAC encoder/decoder support, Intel Media SDK support for accelerated video encode/decode on embedded Linux and Windows, OpenCV improvements, CineForm support, and more.
