Last updated: January 23, 2025 — 6 Comments

This simple tutorial shows how to install the latest version of libheif library, for better HEIF and AVIF image formats support, in Ubuntu 24.04, Ubuntu 22.04 and/or Ubuntu 20.04 LTS.

Libheif is a popular free open-source library for encoding and decoding HEIF and AVIF. Which, also has partial support for JPEG-in-HEIF, JPEG2000, uncompressed (ISO/IEC 23001-17:2023) capabilities.

It supports libde265 and/or ffmpeg for decoding HEIC images, and x265/kvazaar for encoding. For AVIF images, it uses either AOM/dav1d for decoding, and AOM/rav1e/svt-av1 for encoding support.

As well, it has command line tools to convert HEIF/HEIC to other images, and convert images to HEIF/HEIC.

Many popular applications, including GIMP, Darktable, ImageMagick, Krita, and gThumb, use libheif for HEIF and/or AVIF support. And, the library is usually installed as dependency along with them.

Chromium to Allow VA-API Hardware Decoding in Linux Wayland

Last updated: January 8, 2024 — Leave a comment

For Chromium user, the popular web browser is finally to allow VA-API hardware decoding for video playback in Linux Wayland.

Chromium so far does NOT officially support VA-API Video Acceleration API on Linux. However, there are experimental flags to enable this feature, which might work on certain configurations, but without guarantees (See the official Docs).

This experimental feature however does not work in Linux with Wayland session. Meaning the most recent Ubuntu, Fedora, & other Linux with GNOME Desktop.

Just few days ago on Saturday, Chromium source merged the request to “allowing VA-API on Linux Ozone/Wayland“, submitted by JianHui J Dai.

VaapiWrapper has been updated to remove the usage of libva-x11 and the legacy VaapiVideoDecodeAccelerator, in favor of libva-drm only. This means now Linux Ozone/Wayland can share the same code path as Linux Ozone/X11. See CL:4938496.

This CL removes the remaining libva-x11 codes from Ozone and VaapiWrapper, and allows VA-API by default on Linux Ozone/Wayland.

Linux 6.7 Released with Many New Hardware Support (Kernel PPA)

Last updated: January 8, 2024 — Leave a comment

Linux Kernel 6.7 is finally released! Linus Torvalds announced the release on Sunday night:

So we had a little bit more going on last week compared to the holiday week before that, but certainly not enough to make me think we’d want
to delay this any further.

End result: 6.7 is (in number of commits: over 17k non-merge commits, with 1k+ merges) one of the largest kernel releases we’ve ever had, but the extra rc8 week was purely due to timing with the holidays, not about any difficulties with the larger release.

The new Kernel release has many new and improved hardware support!

For Intel, the Turbostat command utility now supports Lunar Lake and Arrow Lake (15th gen) processors; LPSS (Low-Power Sub-System) driver now support Lunar Lake M processors; The Meteor Lake (14th gen mobile processors) graphics support now considered stable.

All the newest AMD Radeon RDNA2 and RDNA3 GPUs with Display Core Next 3.0 has Seamless Boot enabled.

And, NVIDIA has GSP support in the open-source Nouveau driver for initial GeForce RTX 40 acceleration support and improved RTX 20/30 series hardware support.

Lossless Cut – Swiss Army Knife of Video Cutter added Full-Screen Support

Last updated: January 5, 2024 — Leave a comment

Lossless Cut, the popular free open-source video cutting/trimming tool, updated recently with full-screen support.

There are a few tools to cut out a fragment of a video in Linux, besides using heavy video editor application (e.g., Kdenlive and OpenShot). They include Video Trimmer, VidCutter.

However, Lossless Cut is my top favorite one! It lets you quickly extract the good parts from your videos and discard many gigabytes of data. It’s extremely fast because it does almost direct data copy instead of re-encoding with the power of FFmpeg library.

For Ubuntu 22.04/23.10, Fedora & other Linux with Wayland, Shutter screenshot tool can finally take screenshots for selected area and app windows!

Shutter is (or was) an excellent feature rich screenshot tool, with image editing and uploading support.

It was one of my top favorite apps, but removed from Ubuntu repositories due to lack of maintenance. Though, it’s later added back to system repository, thanks to open-source community’s work by porting it to GTK3.

How to Install xxHash for faster hash check in Ubuntu

Last updated: January 1, 2024 — Leave a comment

This simple tutorial shows how to install the most recent xxHash for faster hash checking in Ubuntu Linux.

xxHash is extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It can be useful to check integrity for large amounts of data, index data, and/or used in cryptographic applications like digital signatures.

The library includes the following algorithms:

XXH32 : generates 32-bit hashes.
XXH64 : generates 64-bit hashes.
XXH3/XXH128 (since v0.8.0): generates 64 or 128-bit hashes, using vectorized arithmetic.

I’m new to hash algorithm, but doing hash check regularly when trying out different Linux distributions. And I use sha256, since the most sites provide sha256sum files for the hash code of their disco images.
