Hello !
Is lavaudio making upmix from 2 channels to 5.1 ?

Status sais it does, but only front right and left have sound, other channels are just silent.

Hi,

One quick question: does LAV splitter support push source filters?

No, it does not.

Is there a way to force playback of English AC3/DTS over PCM type tracks? Sometimes the default track is PCM with optional multi-channel track. I'd obviously like forced playback of the multi-channel track without having to remux.

nevcairiel · 11th December 2012, 13:16

The track with the highest number of channels is always preferred, unless you have a MKV file with an actual "Default" marking, in which case it cannot be overriden.
You can fix such MKV flags without a full Remux, simply use the header editor of mmg.

It also depends on the player. In MC you can select your prefered track the first time and it will be remembered for subsequent playback.

Will Lav support DVD navigation? Or are there any "recommended" alternatives?

It would be great to see Lav's (simple) blueray navigation extended to DVDs...

Thanks! Lee

Not really a solution for the future but it is worth noting that you can get the WMC pack for Win8 for free from Microsoft until sometime in January.

Edit: Oops, that only applies to Win8 Pro. Sorry.

Hi Nev, all. Can anyone reproduce corruption at 5-6 second mark in this TwinPeaks clip

Twinpeaks1080p30fpsRef2-27Mbps.mov

Its about 10% the height of the screen and 100% width, like a horizontal block of blurred image. It only happens in software decoding mode, not cuvid decoding mode.

nevcairiel · 12th December 2012, 20:23

The corruption also happens in CUVID mode, but its not as obvious because the hardware does better error concealment, the file is just broken there.

mark0077 · 12th December 2012, 20:33

ahh nice one, thanks v much.

Stereo AC3 in avi container do not work in Windows Media Center. In WMP there is no sound, in WMC can't open file
Video Format: AVI
Audio Format: AC-3, Bit rate mode: Constant, Bit rate: 192 Kbps
Channel(s): 2 channels, Channel positions: Front: L R
Sampling rate: 48.0 KHz, Bit depth: 16 bits

Is there some tip or workaround? Thanx.

Are you sure either of those programs is using LAV? IIRC, neither of those actually lets you choose which codecs it uses, a prime example of the need for system-wide codec settings in the Control Panel (which can be protected from unwanted changes), rather than relying on merits and programs deciding what's best by themselves.

DragonQ · 14th December 2012, 17:32

Oooh the beta of MediaPortal 1.3.0 lets you choose your own splitter. I wonder how LAV Splitter will handle live TV in this environment.

Only for Video, not for TV (or Blu-ray)

DragonQ · 14th December 2012, 19:32

Ah, I see.

EDIT: Hmmm that's weird, using LAV Splitter + EVR in MediaPortal 1.3.0 Beta plays videos that have dodgy playback in MPC-HC perfectly. Wasn't expecting that.

Yes I'm sure. It's not so difficult. Any other answer?

G_M_C · 15th December 2012, 22:44

I have a question: I just tried a '2-in-1' type mkv, and is noticed lavfilters didnt show the 2 separate streams. Is it something i confugured wrongly, or dont the lavfilters support 'x-in-1' type mkv's ? And if not, will they support it soon?

VictorDUA · 16th December 2012, 00:05

This is easy: check AC3 in LAV Audio AVI in LAV Splitter and play the file:

with WMP and WMC. So any help please.

nevcairiel · 16th December 2012, 08:03

I tried playing that file in WMP with both 0.54.1 and the latest development version, and it plays just perfectly with LAV Splitter and LAV Audio.

Superb · 16th December 2012, 08:24

Works well here as well. Tested w/ 0.54.1 on WMP, WMC, and MPC-HC.
Note that Microsoft built-in filters are turned off on my machine, so that LAV will be used.
