    AV1 decoding on the AMD GPU on APUs would definitely be a good thing for laptops / low power PCs... With Firefox slowly enabling VA-API on Linux and hopefully sometime later chromium will follow too, this could be a story for longer battery live by default, when watching videos in the browser on mobile devices.

    I don´t really see the benefit of having a dedicated Encoder part in your GPU. It eats away valuable chip area and is used really seldom. In reality, only Game Streamers probably use it. Video Conferencing software does CPU encoding 99% of the time. Creators typically use the CPU based encoders as they offer better compression/quality.
    I'm not a game streamer/creator, I do Skype/Zoom/Conference call, screen sharing/recording, send video on telegram/other app that would resample/compress video before sending, chopping recorded videos, etc.

    They can't add support for something that did not exist when the hardware was designed.

    What people seem to miss is that it seems AMD likely crippled the h264 silicon to make room for hevc. The fixed function hardware doesn't always overlap and just making the chips bigger and bigger to fit more and more codecs over time isn't practical. Its where part of that Intel / Nvidia premium goes.

    So in the same vein in ~5 years when new hardware has av1 encode and decode expect the vp9 and hevc support to diminish or drop.

    The usual lead time between standards and first VPU (dedicate Video Processing Unit) silicon is typically around 18 months (sometimes a bit less, sometimes a bit more, depending on the details of the standard), although FPGA implementations typically happen much sooner. And it is more like three to four+ years before such decode units become ubiquitous in many shipping SoCs.

    Due to the complexities of an encoder, hardware based solutions are less and less useful for encoding. The encoding algorithmic flexibility is increasing by the day so a general purposes processor is actually the best for encoding. The only reason you would need a hardware encoder is for fast latency with low complexity (low quality) encoding selection.

    A notable userbase.

    Ughhhhh are you kidding me...........

    ...so they nerfed the H.264 encoder even further, instead of improving it. Ugh.
    This only makes me want to move to Intel or even half-baked NVIDIA *sighs*
    Is it THAT hard to improve SOMETHING?!
