  • Google Has Been Developing "libgav1" As New AV1 Decoder

    While there exists DAV1D as one of the most promising AV1 decoders to date, Google has been developing libgav1 as its own AV1 decoder and focused on Arm-powered Android devices but also x86_64 desktop CPUs as well.

    Google made its first libgav1 code drop on Friday for this AV1 decoder focused on AV1 profile 0 and profile 1 content. GAV1 is focused on decoding IVF files and so far features the likes of Arm NEON and x86 SSE4.1 CPU optimizations.

  • DAV1D vs. LIBGAV1 Performance - Benchmarking Google's New AV1 Video Decoder

    With the surprise code drop of Google developing a new open-source AV1 video decoder as "libgav1", I set out this Saturday to run benchmarks on various systems for seeing how the performance is looking for this CPU-based decoder in relation to the more well known DAV1D decoder.

    Libgav1 is now available alongside the many other video encoders/decoders for benchmarking via the Phoronix Test Suite with OpenBenchmarking.org. I fired up a number of different Linux systems so far in seeing how the performance compares with a wide array of AMD and Intel processors.

LibreOffice can open documents in many formats, including Microsoft Office files (.docx, .xlxs, .pptx). But it’s native file format is the fully open and standardised OpenDocument Format (ODF). At the recent LibreOffice Conference 2019 in Spain, community members gave presentations about news and updates for ODF. So, here are the first videos from the presentations (use headphones for best audio quality).

Introducing ‘Stealing Ur Feelings,’ an Interactive Documentary About Big Tech, AI, and You

Filed under
Movies
Moz/FF

The six-minute documentary explains the science of facial emotion recognition technology and demystifies how the software picks out features like your eyes and mouth to understand if you’re happy, sad, angry, or disgusted. While it is not confirmed whether big tech companies have started using this AI, “Stealing Ur Feelings” explores its potential applications, including a Snapchat patent titled “Determining a mood for a group.” The diagrams from the patent show Snapchat using smartphone cameras to analyze and rate users’ expressions and emotions at concerts, debates, and even a parade.

The documentary was made possible through a $50,000 Creative Media Award from Mozilla. The Creative Media Awards reflect Mozilla’s commitment to partner with artists to engage the public in exploring and understanding complex technical issues, such as the potential pitfalls of AI in dating apps (Monster Match) and the hiring process (Survival of the Best Fit).

“Stealing Ur Feelings” is debuting online alongside a petition from Mozilla to Snapchat. Viewers are asked to smile at the camera at the end of the film if they would like to sign a petition demanding Snapchat to publicly disclose whether or not it is already using facial emotion recognition technology in its app. Once the camera detects a smile, the viewer is taken to a Mozilla petition, which they can read and sign.

  • Stop video autoplay with Firefox

    You know that thing where you go to a website and a video starts playing automatically? Sometimes it’s a video created by the site, and sometimes it’s an ad.

There isn't any AV1 video decode/encode built into the video engines of today's GPUs, but the DAV1D project CPU-based AV1 decoder is experimenting with offloading some aspects of the process to current generation hardware with OpenGL ES and Vulkan.

There are experimental branches of the dav1d decoder that exploit OpenGL ES and Vulkan for offloading some elements of the decode process to the graphics hardware. At the moment Self-Guided Restoration (SGR) and Constrained Directional. Enhancement Filter (CDEF) is among the functionality implemented for OpenGL ES / Vulkan.

Another couple of months have passed since we last pushed out a release, and so, in our ongoing efforts to produce the best media software in the world, it's time to squash another few of those more irritating bugs. Usual rules apply: don't expect any new features, don't think that this will change your life, it won't make you richer or more attractive, but it will hopefully be more stable and usable for people who've been victims of any of these bugs.

So, what have we done? Well, you can find a full summary of closed pull requests here, but the summary would be...

The popular media player mpv is renamed as Celluloid and released latest installment.

Celluloid (formerly GNOME mpv) is a GTK+ based free and open source media player. Celluloid is very lightweight and can easily be adapated as an alternative to popular VLC Media player. This slick media player interacts with mpv via the client API exported by libmpv, allowing access to mpv’s powerful playback capabilities.

Some notable features of Celluloid includes the implementation of MPRIS D-Bus Interface which allows for better integration with desktop environments that have compatible MPRIS clients, fully functional Wayland support.
