Good job Intel and Intel!

won't be any gpu's able to decode this in a while, and its hard on cpu's.

What really bugs me is the fragmentation. VVC will be out late next year.

this decoders developing quickly, it was single threaded last i looked o.o
spoken by someone who really doesn't have a clue lol.
last i saw measurements done, this codec was only capable of single threaded decoding and that limits your device coverage to the top end parts with high single core ipc.

MPC-HC lastest build supports AV1 SW decoding. On my 5960X@4.4Ghz all 16 threads are used and 4K videos are not totally smooth for now.
MPC may require some additional optimizations but without an HW decoder most of the CPU won't be able to decode it.

Well this didn't say anything... what bitrates and resolutions? what about HDR? which processors will support it?
just an empty announcement

Blue is normalized Reference decoder. Then you see improvement on each platform.
It does not necessarily mean that It is faster on Zen.
it means that dav1d decoder provides much higher boost in performance on Zen platform in comparison to reference than it does on haswell.
Either way, use of better decoder provides 3 times the performance on intel and 4 times for AMD in comparison to just using reference.
Those decoders are new and clearly far from optimized.
What decoder MPC-HC uses?

I have not tried recently but mid-march LAV filters (which MPC is based on) were updated to use dav1d:
NEW: Using the dav1d AV1 decoder for significantly improved AV1 decoding performance

So maybe I should retry š

original presentation at VDD where I talked about the multiple types of multithreading used in the decoder, why that is special and why it makes it so much more fast than other implementations that only use a single type of threading.
With dav1d, decoder performance has become a non-issue. It is solved. The next step in the toolset generation for AV1 is to reduce power consumption, i.e. hardware decoders, in particular for mobile devices such as laptops and phones to enhance battery life and reduce heat generation; and faster/better encoders, in particular when it comes to visual quality.
One of the authors of the decoder here - dav1d has always been multi-threaded. See the Yxskaft
Forcing AV1 on youtube's testtube and trying the Halo Infinite trailer in 1080p, it stutters alot on both my Phenom II X4 and A10 8700p. That's using Firefox and Chrome, Edge says it doesn't support AV1 playback.
My Nexus 7 tablet couldn't play HEVC 1080p samples smoothly back when I tried it.
