It always stores in the same registry key.
HKEY_CURRENT_USER\Software\LAV

MPC-HC stores the settings in a different key if you use the internal LAV Filters. It takes over settings management through API of LAV Filters.
HKEY_CURRENT_USER\Software\MPC-HC\MPC-HC\Internal Filters

The change in behavior is purely because you changed/reset settings.

Thanks.

Though something indeed happens. LAV is not loaded, but apparently the microsoft decoder does. But somehow deinterlacing doesn't break on channel switching either. (It breaks when I set the microsoft decoder to be used directly)

Hello everyone. I would like to ask if anyone can suggest to me what I should do: I mix the back and side channels together, therefore the output comes out as 32bit Float (PCM from WASAPI) instead of the one closest to the file's native.

My receivers support up to 24-bit according to Windows, but 32bit output (from files or mixing) plays properly. Should I disable 32-bit outputs on LAV or leave it be?

Thank you in advance.

Generally, you should just leave everything on and let the audio renderer deal with it.

I see, thank you. Is there anything else I should pay attention to?

I have PotPlayer's WASAPI set to bitexact mode and the default speaker output to "Same as input" and "32-bit (floating point)" - which for some reason do affect audio even though I thought they would not with LAV enabled.

For example; setting 32-bit on PotPlayer for some reason makes the volume slightly higher and changing the speaker output from "Same as input" to 5.1 seems to change output type, but I assumed "Same as input" is best considering LAV is enabled.

Are there any "best settings" to set these in order to avoid interference with LAV?

Evening I'm using MPC-BE with Madvr and LavFilters. Now, i'm not an expert so this is my actual configuration of audio and video lav. Are configured properly?

I'm experiencing an issue with an mkv with audio track in 'eac3' format. When opening it, i hear no audio. In the filter list there is no lav audio but there is Microsoft DTV-DVD audio decoder. With other audio format, like 'aac' i've no problem and i hear audio and see the audio lav filter active.

Btw this is my configuration:

In MPC-BE Internal Filters i've all of them deselected in 'Source Filters', 'Video Decoder', 'Audio Decoder'.

You may need to disable E-AC3 bitstreaming if that happens, perhaps it isn't supported on your setup - which would cause a fallback to another decoder.

What does your AVR display if you check the audio stream info? Does it recognize the Dolby Digital Plus stream correctly?

In MPC-HC there is an option to add specific external filters which you can then set a merit for, or block, or prefer.
If you want to avoid the MS Decoder and there is the same option in MPC-BE, try to add LAV Audio Decoder and set it to Prefer.

Is this the only file with E-AC3 you have a problem with? If you don't have any other, there are some here: MPlayer samples collection - E-AC3
Play them to see if it works with other files.
If the problem is only with one specific mkv, post its MediaInfo output here (only the section for audio)

Yep, disabled and now works What you mean for "not supported on my setup"?

Tried with others eac3 from link you posted and same problem, i've to disable the eac3 bitstream to hear them work.

I've all lav filters configured as Preferred yet.

How can i see the AVR btw?

Thanks!

What are you outputting sound to? Is it an all-in-one kit? A receiver?
Probably as nevcairiel said, your sound system can't decode Dolby Digital Plus.

Then you should probably disable all bitstreaming options.

Because headphones usually don't have bitstream decoders for those compressed formats.

Bitstream = output encoded (ac3, e-ac3, dts etc.) audio signal
So your headphones need a built in decoder for all this formats or otherwise you will hear nothing (i.e. your test with bitstream).

P.S. I would really like a fallback in LAV for not supported bitstream formats, because many users are running into this problem.

it would be better if people stop checking a check box because they can.

Well, of course i should have searched the solution because it's a well treated argument.

But after all i checked the option and then asked here, so i think this discussion is for help too, so i can learn and help others with same problem

Hello,

I have a problem with the lavfilters:
I can't bitstream DTS-HD HRA.

My reveiver (Onkyo RZ900) display only DTS but no sound.

No problem with other (Dolby Digital +, TrueHD, DTS or DTS-HD MA, DTS:X).

Even with latest nighly builds, same error...

I have tested many things, change all options in Lav Filters, but no luck

I am forced to uncheck each time the bitstream to activate the PCM conversion...

On some forums, they talk about a problem in the DTS header that would not be recognized on some amp.
Apparently when playing a DTS HD MA before the HRA track, the bitsream would work well (I did not manage to test)

Can you help me ? I have many BD with DTS-HD HRA tracks...

Thanks in advance

My config :
Windows 10 (latest update)
NVIDIA GTX 1070 (latest NVIDIA drivers)
Onkyo TX-RZ900 (latest firmware)
Latest MPC HC (nightly build)

LAVfilters two versions?

Is it possible to have two versions installed?
I use BD-RB which requires LAVfilters 0.65 for avoiding audio sync issues.
Would like to use LAVfilters 0.70.2

What player do you use? MPC-HC comes with an internal LAV version.


(I know BD-RB users seem to stick to certain versions but I doubt using the latest will actually pose any problems.)
