Makes sense, although perhaps an option to override the default flag for audio/subs would be useful. I've yet to find a case where the default flag was used for a purpose other than to ensure decoder compatibility by the author of the file.

I always set primary audio streams to "default" over secondary streams (e.g. director commentaries).

And just to be safe, the "concat" protocol used in those demonstrations is not available in LAV either (and never has been).

LAV Filters - DirectShow Media Splitter and Decoders

Installation, disabling rtp. LAV splitter, rtp enabled. The rtp links do not open. Installation, rtp enabled. Lav splitter, rtp disabled. rtp links open. Checked on the player which not plays rtp without lav filter.

Checkbox disable/enable all the components. I disabled everything and I choose what I need and enable.

A difficult captcha from questions I don't know all the answers. And I don't know English.

LAV supports the .mk3d extension, file associations are managed by the player however, and not the splitter.
do you have any plan to support 3d bluray or ssif files in the near future? it is a important feature. with 3d bluray support, we can throw PowerDVD out of the window.

btw, thank you for your work

Enable or disable rtp in the menu LAV splitter is ignored. RTP is always as selected during installation LAV. 62

Is it possible to modify the audio delay in LAV Audio to apply to specific refresh rates (e.g. 24 Hz)?

I have problems with audio sync at 24 Hz when playing 23.976 fps content. Other refresh rates are fine. This problem is reasonably common.

- Plex Media Player has a built-in delay for 23.976 content (see bullet #9).

- Kodi offers the ability to set delays for specific refresh rates (described here).

- There is an entire thread dedicated to this issue in the Kodi forums (found here).

Adding a refresh rate-based delay in LAV Audio would open up the ability to apply this type of correction universally to any player that uses LAV Filters.

I don't think LAV even knows the current display's refresh rate, does it? That sounds more like a player feature to me, I can see it being useful but I think it is important to keep LAV's feature list as light as possible.

If I understand this correctly, these features are compensating for different amounts of input lag in the display due to it using different modes with different refresh rates, not desync between the audio and video as it leaves the computer?

Asmodian is right, LAV Audio of course doesn't know the current refresh rate, it has nothing to do with video afterall, and I'm not exactly eager to add stuff to try to detect the current refresh rate, especially considering things like automatic display mode changers and whatnot.

since madVR and more generally any players who uses this feature determines the refresh rate starting by the frame rate, lav could do the same for the audio delay and give two possibilities to set the value, the current method or an advanced text string as madvr does

something like

1080p23@-300, 1080p50@-150 ...

just an idea

LAV Audio also doesn't know the frame rate of the video, it deals with the audio, not the video. And such guesses would be extremely inaccurate anyway, and I don't do broken features. Just get whichever player you are using to do it.

hi nevcairiel,
could you make the installer skip downloading decoder if it alreadys exists?

Even if LAV has to be responsible for A/V delay it would be the Splitter but actually the Player has to take care of it and to be honest I never experienced any delay regardless of the displays refresh rate. Maybe because I use digital connection between the playback device and the display.

Do you use an external Amp/Surround system?

Understood. I thought adding this feature further up the chain would make it easier to implement for the end user.

At some point I could implement an option to do video delay (instead of audio delay) in madVR, depending on refresh rate. But probably not any time soon.

Given the cause of this still remains unknown to the developers I've talked to, the player is simply delaying the audio by a preset amount before it outputs to the audio output device.

The Kodi thread has people blaming a number of features and claiming solutions found in the Kodi audio settings. But, in my experience, I think it comes down to the display lagging when it uses its 24 Hz mode. In either case, an easy fix is to add a delay to 23.976 content.

Sure, it could also be the AV receiver struggling to lock-on to 24 Hz content. But I've used a very new and a reasonably old (2-3 old) Onkyo and they both display this flaw.

I think it could be a flaw of some LED TVs. They all struggle with motion in some way. I am using a very common, supposedly high-end Samsung LED.

this issue is called input lag. TV can have easily an input lag of over 100ms there are even TV with an input lag of over 200 ms.

this changes with refresh rates and settings like crappy frame interpolation and TV mode like game(low delay)/cinema(very high delay).

Many TVs have input lag defined in number of frames (due to their processing), which makes it noticeable longer on 24Hz since frames are just so much longer (41.6ms instead of 16.6ms at 60Hz)
