VideoLAN Announces Dav1d, a New Libre and Open Source AV1 Decoder (jbkempf.com)

Jean-Baptiste Kempf, president of VideoLan and developer of VLC media player, made the following announced Monday: AV1 is a new video codec by the Alliance for Open Media, composed of most of the important Web companies (Google, Facebook, Netflix, Amazon, Microsoft,...). AV1 has the potential to be up to 20% better than the HEVC codec, but the patents license is totally free, while HEVC patents licenses are insanely high and very confusing.

The reference decoder for AV1 is great, but it's a research codebase, so it has a lot to improve. Therefore, the VideoLAN, VLC and FFmpeg communities have started to work on a new decoder, sponsored by the Alliance of Open Media. The goal of this new decoder is: be small, be as fast as possible, be very cross-platform, correctly threaded, libre and (actually) Open Source.

    For all intensive purposes, this has peaked my interest in one foul swoop.

    LOL nobody uses H.265 in wide distribution because nobody can afford to with the multiple patent pool licensing. It's dead, and will never generate the revenues needed to fund development of any further standard. MPEG killed the golden goose and sent their members to build their own org to cut them out, and AV1 is the result.

    The codec will get faster with optimization and forthcoming hardware en/decode acceleration, just like all codecs do.

    Nice FUD though.

    What were you saying about HEVC being too expensive to be available in less-expensive devices?

    $40 for a 4k HDR h.265 Roku is pretty much mainstream. Which means aV1is dead-in-the-water.

    AV1 hardware acceleration will be TWO YEARS behind the $40 Roku, and you can be sure that it will cost OVER $100 o release (like the first 4k Roku).

    HEVC enjoyed early adoption beause of early phone spec war. My Galaxy S4 had HEVC playback built in,

    HEVC encode support was added to devices after the S4 a Apple, because video storage space is limited on a cellphone. The TVs have actually been slow to adopt HEVC compared to the rest of the industry, but 4k TVs with HEVC haw been around fo five years now, an 4k BluRay is almost two years old. Both are standard devices that don't support AV1.

    The other upcoming standard hat will also kill AV1 is ATSC 3.0.
