LAV Filters - DirectShow Media Splitter and Decoders

[Asmodian]

I wonder if Lentoid HEVC set LAV's merit very low.

This is a free utility that makes it easy to see and change filter merits:
InstalledCodec
LAV Video and Audio should be 0x00800003, LAV Splitter should be 0x00800004 (values in hex). Higher merit is the first to be used.

Very late last night (I write from Europe) I solved it by completely uninstalling LAV and then reinstalling (before I was upgrading and downgrading in place, not passing through uninstall).

I am sorry not to have tried what you suggested because I'm left with the curiosity to understand what happened.

LAV's merit being set very low could be an explanation but can you set the merit of a DS filter only for a specific codec? Because H264 material was working just fine. And, also, with Kodi DS player you can tell the program which filters to use, ignoring the merits system. And yet it wasn't working.

Mystery will probably remain but I have solved the problem.

I see this on Formula 1 too, on onboard cameras the white/coloured pattern on the kerbs changes too much between consecutive fields and it confuses the deinterlacer.

No new nightly builds available?

There should be one tonight

LAV Filters 0.75.1

LAV Splitter
- Changed: AV1 files with no extradata will now generate a format header with stream information for decoders to use
- Fixed: Improved stream selection when multiple "default" video tracks are present

LAV Video
- Changed: Updated dav1d for significant improvements in AV1 10-bit decoding performance
- Changed: AV1 hardware decoding will more reliably engage when provided with additional stream information from the demuxer

LAV Audio
- Fixed: Opus decoding had audible artifacts in some files in 0.75

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

Check 0.75 Release Notes if you missed them!

AV1 software decoding of 10-bit content is now significantly faster with the new version of dav1d.

Other then that, just few small fixes and updates.

Take care, and have fun!

Cheers!

Edit: I am using BeHappy 0.3.0.19814 and Monkey's Audio Console Front End 3.99 as encoder. I am using LavFilters 0.75.

@nevcairiel:

Please check this.

@GMJCZP
The problem is not with LAV Filters. The problem is with FFmpeg or your file.

FWIW: latest Monkey's Audio is version 6.29 :-|

Since this issue was confirmed, FFMpeg has nothing to do with it. The file plays correctly in a player that does not depend on Lav filters.

You mention problems with an .ape file and link to a MP3 file. There is nothing to look at.

Sorry, upload corrected:

Deblocking videos by ffdshow doesn't work on latest version of MPC-HC, So please add deblocking to LAV if possible.
Thanks

Maybe you have an issue with it's installation or something? Reinstall it and check your external filter list.

Hi, getting an odd volume issue with lav filters, been noticing i'm having to max out my headphone volume for movies recently to the point where they are just not loud enough. I first thought it was just the mix as they sound ok through my speakers but when I play the same movie using VLC, windows media or film and TV player they are much louder and much more the volume i'm used to. I've tried reinstalling LAV filter, no joy, I dont have DRC turned either.

Any ideas anyone?


EDIT - tried it with bitstreaming on / off - no difference.

What about Normalize Matrix?
