FFmpeg Devs Boast of Up To 94x Performance Boost After Implementing Handwritten AVX-512 Assembly Code

Anton Shilov reports via Tom's Hardware: FFmpeg is an open-source video decoding project developed by volunteers who contribute to its codebase, fix bugs, and add new features. The project is led by a small group of core developers and maintainers who oversee its direction and ensure that contributions meet certain standards. They coordinate the project's development and release cycles, merging contributions from other developers. This group of developers tried to implement a handwritten AVX512 assembly code path, something that has rarely been done before, at least not in the video industry. The developers have created an optimized code path using the AVX-512 instruction set to accelerate specific functions within the FFmpeg multimedia processing library. By leveraging AVX-512, they were able to achieve significant performance improvements -- from three to 94 times faster -- compared to standard implementations. AVX-512 enables processing large chunks of data in parallel using 512-bit registers, which can handle up to 16 single-precision FLOPS or 8 double-precision FLOPS in one operation. This optimization is ideal for compute-heavy tasks in general, but in the case of video and image processing in particular. The benchmarking results show that the new handwritten AVX-512 code path performs considerably faster than other implementations, including baseline C code and lower SIMD instruction sets like AVX2 and SSSE3. In some cases, the revamped AVX-512 codepath achieves a speedup of nearly 94 times over the baseline, highlighting the efficiency of hand-optimized assembly code for AVX-512.

Apophis: a European space mission gets up close with an asteroid set to brush by Earth


The European Space Agency has given the go-ahead for initial work on a mission to visit an asteroid called (99942) Apophis. If approved at a key meeting next year, the robotic spacecraft, known as the Rapid Apophis Mission for Space Safety (Ramses), will rendezvous with the asteroid in February 2029. Apophis is 340 metres wide, about the same as the height of the Empire State Building. If it were to hit Earth, it would cause wholesale destruction hundreds of miles from its impact site. The energy released would equal that of tens or hundreds of nuclear weapons, depending on the…

EU funding powers 10% of European startup ecosystem, study finds


About one in every 10 European startups that have raised VC investment are also backed by an EU grant of equity financing, according to a research project conducted by Dealroom and Dealflow.eu. While the full report is expected to be published later this year, the authors presented a few preliminary numbers in Warsaw last week. In financial terms, the 10% share translates into EU-backed startups having raised €70bn in VC funding since 2010, or some 11% of total funding in Europe (which in this case includes the EU, Switzerland, Norway, UK, and Israel). With some €400bn in total enterprise value…

Battery recycling startup Tozero bags €11M to boost Europe’s lithium supply


In 1991, Sony brought the first rechargeable lithium-ion battery to market. The unique chemistry proved a game-changer in energy storage. Today everything from EVs to smartphones depends on it, with demand skyrocketing.  But lithium is rare, most of it comes from unstable markets outside Europe, and its extraction can cause extensive pollution. We need more lithium to enable the green transition and yet, currently, its use is unsustainable — both environmentally and economically. We’re stuck in a paradox. Munich-based startup Tozero believes that battery recycling offers a way out. Recycling batteries is far from a new concept, but the German venture…
