You probably don't have hardware level support for the VP9 codec, when YouTube switched to that my laptop at the time would run it's fans at 100% just to play a

  I remember playing DVDs on 20-ish year old hardware. Even without a hardware decoder, I can't imagine how a modern CPU is unable to handle simple tasks like video decoding. Maybe its the higher bitrate..

    >Maybe its the higher bitrate.. An HD Netflix stream has about the same bitrate as a DVD, but has drastically better image quality. Modern codecs are extremely efficient in terms of bandwidth, but that comes at the cost of computational complexity. Decoding HEVC or VP9 is far from a simple task; hardware acceleration of video decoding is absolutely crucial for power-constrained devices like smartphones and laptops.

      > Modern codecs are extremely efficient in terms of bandwidth, but that comes at the cost of computational complexity Right, but as with every codec, the cost is always heavily skewed towards encoding the stream. >Decoding HEVC or VP9 is far from a simple task; hardware acceleration of video decoding is absolutely crucial for power-constrained devices like smartphones and laptops. I don't believe that decoding video streams should come anywhere close to saturating a modern CPU in 2018. The hardware acceleration you mentioned isn't magic, and doesn't use any crazy tech either. Its going to be some kind of low powered ARM chip on MediaTek SoCs like the MT8581.
