LAV Filters - DirectShow Media Splitter and Decoders

[huhn]

use 60 always. 30 and 25 as target is only interesting for encoding or detelecine not deinterlacing.

It is not just metadata. DRC is the key feature of eac3, that allows to increase the compression/quality

For me compression is destroy the quality of the original source.

It was a help for old players, but with new smart players the compression can be done on the fly and apply it for all codecs when it is necesary, not forced with the Dolby settings.

LAVFilters-0.78.0-9.exe is incomplete. Can you fix it?

[nevcairiel]

LAV Filters 0.79

LAV Splitter
- NEW: Support for demuxing VVC video
- Changed: Updated language lists to support all relevant language codes
- Changed: Improved resilience of streaming HLS
- Changed: Tweaked frame rate detection logic

LAV Video:
- NEW: Support for decoding VVC video

Download: Installer (both x86/x64) -- Zips: 32-bit & 64-bit

Another update primarily for updating FFmpeg, which brought us VVC decoding. The decoder is still under development and considered experimental - and of course software only and not fully optimized yet.

In the last weeks i've also replaced my hosting infrastructure for the files as well as the Git repositories, but since noone complained much yet, it seems to have been all working so far!

As always, report issues and regressions, in as much detail as possible.

Getting major video stuttering as video player can't understand the frame rate now and instead of trying to display a constant frame rate of say 23.976 it's going down to 21 or 22 frames per second.

Something is wrong with the way this version is reporting frame rates. I'm going to roll back. This release is broken.

Working very well here with Youtube and X264 MKV so far. The better HLS handling is much appreciated. Fantastische Codecs.

If I get issues I'll report back.

Framerate information is cosmetic, its not used for playback - timestamps drive that.

If you want to be helpful, could tell us what the information says before and after, and maybe provide a sample file thats observing such problems. Otherwise its never getting fixed.

Same for me I have to roll back to v0.78
I tried different player (MPC-HC, MPC-BE and Potplayer)

It happens with madvr and with MPC VR. Video literally hitches and stutters every 2 or 3 seconds, like bad frame pacing.

It happens with MKV remuxes in MPC-HC and MPC-BE. Rolling back to the last nightly from 78 worked fine.

[nevcairiel]

The last nightly, as in LAVFilters-0.78.0-10.exe?
That version is completely identical to the release version, other then the version number being changed.

[Sunspark]

I haven't noticed any issues yet.. which decoder are you guys with the hitching using?

[Francois76l]

I rolled back to the last v0.78 version (the one just before your update) and everything worked as usual.
With the last v0.79 version I'm experiencing frame drop and a constant video stuttering every ~2s on a 23.976hz movie.
The rendering time didn't increased

[clsid]

No issue with a standard mkv rip here. Got no other files on current system to test right now.

So guys, please give a sample file that fails.

[Siso]

Just tested it with a mkv movie 1h 40min, no issues here.

[AngelGraves13]

Are the people that are running into issues running a second display at 23.976? That's the setup on the PC with the issue. I'll test at a flat 60hz on my monitor on my second PC when I get home.

Upon further testing...it still does it with 0.79 at 60hz as well.

The last version that's bundled with MPC-HC 2.1.7.2 (might be 0.78.0-5 or 0.78.0-8).

Update: Version 0.78.0-8 works fine.

The file I'm testing is Willy Wonka and the Chocolate Factory 4K HDR that I remuxed with MakeMKV. I also tested a 1080p remux of Goosebumps 2015 and it does the same frame pacing issue with version 79.

Same for me...it's like it's spiking DPC latency.

[Sunspark]

I do output 23.976 to my screen.. no drops or stuttering on 1080p. I'm using a copy-back decoder.

You could try checking "disable full-screen optimisations" on the compatibility tab of the player exe properties, see if that changes anything for you.

But the previous version worked fine.

Can confirm it does it on my other system which has a 4090 RTX.

0.78.0-10 and 0.79 have the problem, 0.78.0-8 does not.

I'm going to assume this is the culprit "Prefer average framerate for reporting, with an accuracy fudge"
