LAV Filters - DirectShow Media Splitter and Decoders - Page 517

Joniii · 11th April 2012, 08:04

Am I missing something? I installed LAV filters to clean Windows 7 SP1, disabled media foundation then used the Win7DSFilterTweaker_5_2 to make LAV video default. Windows still uses it's own decoders for all blu-ray video formats, LAV audio filter and splitter works fine.

The real bug report is that someone made a 10-bit interlaced video.
8-bit progressive is most likely much better quality then 10-bit interlaced will ever be.

Will LAV Audio Decoder eventually offer post-processing like Normalisation and Gain, or is it recommended to use ffdshow or AC3Filter for post-processing, while using LAV Splitter/Decoder for media splitting and audio/video decoding ?

nevcairiel · 12th April 2012, 06:37

LAV Audio will most likely never support Normalisation or things of that sort.

Actually, in this case i would not accept it.
I don't want such a feature.

Yeah, I fully support your stand, nev. Proper normalization can't be done in one-pass scenario so it's not feasible for real-time playback use at all.

Anyone who wants normalized volume should re-encode their material beforehand, period. Otherwise use volume knobs and live with possible clipping, that's all you can get.

I found something interesting today.

LAV was mentioned in the NVIDIA release notes.

I should install 301.24 later, see how things work (on 301.10 right now)

I am stunned these companies do give a sh*t about non-commercial software.

I presume this is unrelated to the madVR problems?

nevcairiel · 12th April 2012, 10:11

Who knows, go try it.
I suspect madVR does something thats not really officially documented to work like that in D3D though.

Its really not a big issue though, just turn off "use separate device for presentation" and everything is fine again.
Doesn't seem to have any bad side effects.

Nvidia have always been pretty good about driver support. AMD on the other hand. On your graphics card is 4-5 years old ? Sorry we won't fix those critical bugs.

madshi · 12th April 2012, 10:55

madVR uses an official D3D feature for the option "use separate device for presentation", namely sharing surfaces between different D3D devices. That feature is rarely used by other software, though, so that's probably why nobody else is affected by what appears to me to be an NVidia driver bug.

There's a chance that we will see a similar changelog entry with one of the next drivers for madVR just like for LAV.

madshi · 12th April 2012, 12:18

Is NVidia even aware of the issue? I'm not sure...

aufkrawall · 12th April 2012, 12:34

The issue has been reported, just like previously the LAV one.
I'm confident that we just have to wait (could take some months though, but we'll see).

madshi · 12th April 2012, 13:42

Where has it been reported? And the LAV one? Do you have a link? Just wondering where to report other issues myself. Thx.

I don't have any more details, I'm sorry.

I don't want to leak private messages information.

You can either report it at the Nvidia forums or send me a PM how to reproduce if it's not too difficult.
Then I can report it to someone else who has better access.
The way via the forums may not be the better one.

Great, thx!
