The seeking might be ok, but beware DSS2mod usually drops the last 1 or 2 frames. 1 frame in this example. You might not "see" it if the test limit was 1000 frames

I should clarify that threads=8 for ffms2 from my previous post is cpu_threads/2. So you can try with that cpu_threads/2.

I got curious and made a couple of tests using different source filters with Atak's SeekTester 1.2. I used the default frame limit of 1000 frames. As the source I took the "Letter - SHE'S.mkv" (VP9 Video 1080p). My CPU is a Core i5 third generation (2 physical cores plus hyperthreading). I used the default thread values for all source filters which would be 4 for this CPU.

FFMS2 StvG from Oct. 2020:
There were 12 corrupted frames out of 1000 frames.

FFMS2 StvG from Aug. 2020:
Same

FFMS2 StvG from April 2020:
Same

FFMS2 StvG from Nov. 2019:
Same

FFMS2 C-Plugin latest 2.31 by qyot27
Perfect

FFMS2 C-Plugin by Reino:
Both available versions fail miserably. Mainly corrupted or inserted frames

FFMS2 official version 2.40 by Myrsloik:
Fails miserably. Mostly corrupted or inserted frames

DirectShowSource with LAV Filters:
Many inserted frames

DSS2Mod with LAV Filters (preroll=15):
Perfect

LWLibavVideoSource by HolyWu:
Perfect


Ok, these results are only for this specific VP9 source file. Other source formats may behave differently, but I find this very interesting. Any comments?

Thanks for sharing.

I meet many corrupted frames in STVG ver with default threads, only work with threads >= 2. But with HolyWu ver, i don't meet error with default threads:

My video test:
https://drive.google.com/file/d/17yc...ew?usp=sharing

My scripts:
nnedi3_rpow2(rfactor=2, cshift="spline64resizemt", fwidth=1920, fheight=1080)
F3KDB_3(range=12, y=60, cb=40, cr=40, grainy=0, grainc=0)
f3kgrain()

[manolito]

Yes, I also had to return to the HolyWu build for exactly this reason...

I believe that StvG should implement a similar logic for the number of threads which he used in his last ffms2 build:

- changed the default threads number:
* VP9 - min(CPU logical processors, 8);
* AV1 - 1 when CPU logical processors = 1, otherwise 2;
* rest - CPU logical processors;

maybe it's time for new update from StvG, since there are new small update here https://github.com/Asd-g/L-SMASH-Works

[StvG]

Update - included the latest commit; ffmpeg@494f868e93; zlib 1.2.11; lsmash@18a9ed2; xxHash 0.8.0; dav1d 0.8.0; changed VP9 default threads to 2 when CPU logical processors > 2.

Awesome, thanks!

@StvG: Are there easy-to-apply patches so that you could e.g. suggest them to media-autobuild suite?

[StvG]

It's not only patches. You need Visual C++ libraries for Avisynth but media-autobuild suite doesn't provide such. If you have them installed then using mingw could be easily used.

[LigH]

Oh, I believe I replied to the wrong thread. I was rather interested in patches for x265 like the aMod by DJATOM.

The DLL works with Avisynth and Vapoursynth.
