Open and optimized VVC Implementations on ARM Architectures

The international video coding standard Versatile Video Coding (VVC) has been finalized in July 2020 by ITU-T and ISO/IEC. In September 2020, the open and optimized VVC encoder (VVenC) and decoder (VVdeC) software has been released and continuously improved in terms of speed and efficiency. Originally developed for x86 architecture, recent optimizations on vectorization target ARM platforms. VVenC and VVdeC runtimes have been measured on various systems to evaluate their performance. Results show that the three fastest presets for VVenC enable encoding HD video with 4 to 25 fps on high performance laptops (Apple M1 Max and Intel i9-12900H) and UHD video with 2 to 10 fps on workstations (Apple M1 Ultra and Intel Xeon Gold 6348). The VVdeC decoder enables live decoding of HD video on a tablet with octa-core ARM CPU as well as live decoding of UHD video on the afore mentioned laptops.
