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.

Thank you !

[kedautinh12]

I seen new commit here, any compile update for this??

[MeteorRain]

It's for my own use. You shouldn't use my version unless you know what you are doing.

Sorry, in the latest binaries from StvG the hardware decoders don't work anymore.
With v20200728 from HolyWu they work.
