Top 7 C++ Codec Projects

  • libjxl

    JPEG XL image format reference implementation

    • Project mention: JPEG XL and Google's War Against It | news.ycombinator.com | 2024-05-02

    > Regarding JPEG XL's mobile support, it makes sense it would see limited development if the company that manages one of the biggest mobile players has been the greatest restriction on their success. The lack of support also disincentivises manufacturers to prioritise support.

    There was literally no involvement from any hardware vendor in the standardization of JPEG XL. It went from a Call for Proposals in Sept 2018 to Committee Draft in Aug 2019 with very little time for industry feedback. Contrast this with AV1 which had involvement from hardware vendors Intel, NVIDIA, Arm, AMD, Broadcom, Amlogic from the beginning as well as companies who ship media on hardware at scale such as Cisco, Netflix, Samsung and yes Google. These companies reviewed and provided significant feedback on the format that made it suitable for hardware implementation.

  • vvenc

    VVenC, the Fraunhofer Versatile Video Encoder

    • Project mention: FFmpeg 7.0 Released | news.ycombinator.com | 2024-04-04

    The built-in VVC decoder is dreadfully slow (a ton of optimizations are missing), VVdec is at least 2-3 times faster on anything having AVX2/SSE4.

    If you really want to give VVC a try, better stay with version 6.1.1 as it's the last one which has patches for enabling VVdec. I won't be able to apply them to version 7.0/git master:
