Nev, today I (finally) tried the big jump from Haali splitter to LAV splitter for matroska.
I was worried how LAV subs selection would work but the Advanced mode can replicate exactly how I had Haali set up, that's perfect. However I notice opening files + going to previous/next chapter is significantly slower with LAV. While it's pretty much instantaneous with Haali, it takes up to 2-3 seconds with LAV. I play the files from local HDD so the "Stream Analysis Duration" setting has no effect. Similarly the "Maximum Queue Memory" setting didn't seem to change anything. I use LAV Video decoder in both cases (when using LAV or Haali splitter).. The video format is h264. Actually the only thing that changes in the chain when testing is the splitter. Would you have any idea what this slight delay could be due to?

Downmixing
Hi
Q: If I set surround mix level to sq(.5) ie 0.701 then does clicking normalize matrix in a 7.1 to 5.1 dowmix actually do anything? ie. Isn't it already normalized? Because I would guess that mixing two channels together at a 0.701 would be 1.0? The reason I ask is because I'd like have my cake and eat it to, ie 1. Avoid a large reduction in dynamic range/volume due to the normalization 2. AND also have settings where clipping is unlikely to happen. I read earlier in this thread that in most situations using clipping protection, you usually only decrease volume by a factor of 1.2x (whereas normalization gives a 2.4x reduction ). So I thought if I set mix level to 0.8 (or maybe sq(0.8)=0.774), and enabled clipping protection I would be in a situation where I had a smaller amount of volume reduction and activation of the clipping protection would be very very infrequent. ie. Mix to 5.1 = Yes Normalize Matrix = No Clipping protection = Yes Surround Mix = 0.8 or 0.774 Is my understanding correct? Thanks Kiwi PS: Well done on adding support for DTS-HD MA and Dolby TrueHD! |

@kiwi
Loudness-wise you're correct, since it means adding the squares, i.e. sqrt(0.5)^2 + sqrt(0.5)^2 = 1. However clipping-wise your wrong, since this means plain adding, i.e. sqrt(0.5) + sqrt(0.5) ~= 1.4. So you either need to normalize by dividing by about 1.4 or use the clipping protection to lower the volume only when needed. |

I tried out the latest nightly, LAVFilters-0.65.0-8.exe, and it caused Staxrip not to work. The issue was the QAAC audio encoder was failing. I tried reinstalling LAVFilters-0.65.0-8.exe with no avail, but version LAVFilters-0.65.0-7.exe seems to work fine. Actually, LAVFilters-0.65.0-7.exe is what I have been running for a few days without this issue.

-8 only had a minor insignificant change in the build script compared to -7, there must be something else broken for you.

I'm running Windows 10 TP, and build 10122 was released. Windows didn't quite update as cleanly as it should have, and the reason why I thought it was LAVF is that I updated it at the same time. Strangely enough, installing the older version immediately made it work for two encodes... until I stopped it and started it again! I previously also reinstalled the Apple Application support etc. So, I ran the latest Auslogics Regcleaner (with all the check areas selected on the left). Could possibly have been a media filter registry error or something... It seems to be working flawlessly now on the latest build of LAV Filters, no matter if I stop and start it again etc. You can download it here: http://www.auslogics.com/en/software/registry-cleaner/ So keep in mind those with Windows 10 TP and on the fast path, that there may be a media filter anomaly after you update! Edit: Well, I stopped and rebooted and started it again (I got curious about it)... Sure enough, it failed continuously (went on to the next file and same thing). Anyways, I stopped it, started it again, dropped it down to the system tray and it works. So, after all that, it could be a NET Framework issue... I don't know lol. Windows 10 10122 issue.

How do I upmix stereo to 5.1 audio? I tried searching for this topic, only to find other people asking to do the same thing. I tried selecting Enable Mixing + Output Speaker Configuration = 5.1... and also selected Dolby Pro Logic II encoding. However, none of that made any difference. I'm hoping I don't have to install ffdshow just to be able to get upmix audio to work, but it's starting to look that way.
I found a directshow matrix mixer which seems to specifically support upmixing. http://matrix-mixer.sourceforge.net/ Last edited by mkanet; 24th May 2015 at 00:59. |

Actually, after thinking about, it does make sense to do this in a postprocessing audio filter.
I did try MatrixMixer's basic stereo expand to 5.1 upmix; however, ffdshow Audio Processor filter (with DolbyPrologicII + LFE crossover + Mixer3/0/2+LFE) gave me the stereo sound processing I was looking for; actually, sounds better than I expected. |

http://www.ac3filter.net/wiki/Download_AC3Filter It's open source now, and could probably do with some work and tweaking etc (and a new build). It still works perfectly fine on Windows 10 x64 though and has included 32-bit and 64-bit versions. You just need to add it to the external filter list of your media player (MPC-HC, MPDN or whatever). |

Ok I can't find this and there's no tooltip for it. I forget what the difference between film and video output mode in YADIF is :S
25/30 means you're outputting 25 or 30 fps? 50/60 means you're outputting 50 or 60 fps? |

for film you usually want to use a detelecine filter not a deinterlancer. |

One question about the system tray icons. Use Lav filters with Subtitle Edit.
So, while the movie is playing icons show is system tray. When I stop the movie, icons are still there... and so on

That happens sometimes when the application is closing the filter too aggressively, and is an unavoidable side-effect. You can just disable the tray icons if you don't want them.
