PipeWire from the start was designed around handling the needs of both audio and video streams on Linux. While PipeWire is already in use for screencasting/recording under Wayland and working with Flatpak'ed applications, recently much of PipeWire's focus has been on addressing the use-cases of JACK and PulseAudio on the sound side. Now that the audio support is in quite good shape, Red Hat engineers are back to focusing on improvements to the video support...

Given this week's release of Fedora 35 Beta I have begun my benchmarking to look at how this next installment of Fedora Linux is shaping up given that it tends to be at the forefront of open-source innovations given Red Hat's investments.

Linux kernel developers have been working tirelessly to squeeze more performance out of IO_uring and the block / I/O code in general. IO_uring lead developer Jens Axboe who also serves as the Linux block subsystem's maintainer (among other roles and major contributions over the years) has used his system as a baseline for evaluating such kernel improvements. He's now moved to using AMD Zen 3 while sticking to Intel Optane storage and is seeing a mighty speed boost out of AMD's latest processors...

While the Linux kernel is increasingly supporting the use of Zstd for various compression purposes, the current Zstd code within the kernel is out-of-date and efforts so far to re-base it against the closer to upstream Zstd state have been stalled. Fortunately, a new attempt at getting the Zstd code updated for the Linux kernel will be published soon...
