I haven't done the tests yet, but i really don't think that dAV1d v0.6.0 has any significant difference for 8 bit videos compared to v0.5.1

But FireWork and Yellowstone are 10 bit HDR and according to test dAV1d v0.6.0 has advantage over previous version.

Sorry, my bad, you 're right.

Using LAV filters 0.74.1-34 I get ~08 fps for Yellowstone and ~12 fps for FireWorks for the first 5% of the clips.
I think it's just the opposite than LAV filters 0.74.1-32

Thanks for new experiment with AV1 and 0.74.1-34 - results are unexpected: Fireworks from 08fps has increased to 12fps and I believe that's good progress but Yellowstone from 11fps has decreased to 08fps (
It seems results are unstable from one run to another.

Nev just updated the decoder any regressions in performance should be reported to the dav1d team.

@VictorLS
@ryrynz

Sorry guys, I've just flipped the clips

Yellowstone is the "tougher" clip ~08 fps using my Core i3 9100F for both LAV 0.74.1-32 (dAV1d v0.5.1) & LAV 0.74.1-34 (dAV1d v0.6.0)

Fireworks Omagari is ~11 to 12 fps for both too (11 is closer to dAV1d v0.5.1 and 12 is closer to dAV1d 0.6.0)

A new test with an other CPU (Haswell)
HEVC 4K 4:2:2 20180428-175510_4K ENC 3 RMAD VS LEG.ts

Core i3 4170 - Win 10 1909 (18363.720)
DXVA Checker v4.2.1
LAV Filters v0.74.1-32 x64

Decoding mode: (FPS)
19/27/45 CPU usage 90% (average)

Tried MPC-HC with MPC VR and looked like a slide show.

Using EVR-CP, it looses sound now and then and stutters at ~30fps using ~90% CPU, dropping a few frames.

8K AV1 Yellowstone using Core i3 4170 gives ~04 fps for both dAV1d 0.5.1 and 0.6.0

Fireworks Omagari is ~05 to 06 fps for both dAV1d versions too.

So no regression and no progression for dAV1d using these clips.

All 8K AV1 tests were done using the first 5% to 10% of the clips, they are just a rough approximation.
(I was really bored waiting to finish decoding at 04 fps or 08 fps or even 12 fps)

An interesting comment would be that Skylake architecture using 4C/4T@4.0GHz is roughly 2x faster than Haswell architecture using 2C/4T@3.7GHz for both HEVC and AV1.

We're two days away from the one-year anniversary of the last official LAV Filters version. Will there ever be another standalone version, or is nevcariel only going to distribute updates via players (MPC-HC, JRiver Media Center, etc) and nightlies from now on?

You'll just have to wait and see, won't you?
I don't make releases just because it has been a certain time since the last one, but when I feel like there are worthy changes to be released. I do have some things I really want to work on, but time has been a factor over the last year. Been barely working on any audio/video stuff.

For the record, I don't actually include any nightly versions in JRiver Media Center, it uses the latest release. What any other players do is entirely out of my control.

Thanks one more time.

Btw my Fireworks was slideshowing for an 1 hour and 3 minutes long = 63 minutes dividing it on 3,5 minutes long of original file I practically (not in DXVA Checker) have 3 and 1/3 fps with my much older and weaker Athlon(tm) II X3 460 CPU

Not complaining, just curious. I remember a comment you made about how end users shouldn't be installing LAV Filters at all. I was wondering if the next major version would only be released to the player devs.

I love what you've done with Blu-ray menus in MC. Most of us are good with the current LAV version anyway.

Does LAV Splitter support idx+rar (archived sub) subtitles as external file?

I tried with an ancient avi and while it worked ok on xbmc, it doesn't on Windows with MPC.

Yes.
I know there are MFT to DirectShow wrappers (I think LAV uses this for WMV decoding), but I have never seen it the other way.

@VictorLS starting from Ice Lake, Intel media engine supports HEVC 4:2:2 decode : https://github.com/intel/media-drive...media-features
Your best bet is to upgrade in the future to a platform that can do hardware decode of that format (note that I'm not sure that would automatically mean it would work with LAV) rather than hope for I-frame only decode.

Thanks for information.
I hope someone Ice Lake processor owner will confirm Intel media engine supports HEVC 4:2:2 decode (with low CPU load, of course) on for example 20180428-175510_4K ENC 3 RMAD VS LEG.ts
