not sure if you need something special from pot player but with MPC-HC/BE you could use lav audio for decoding, ffdshow for processing and still use the build in time shift from the audio switcher/audio renderer.
and a new audio renderer for MPC-HC is coming "soon" too. http://forum.doom9.org/showpost.php?...postcount=1722 |

If you install LAV after Haali, it'll do the same. Both compete for similar functionality afterall, and only one source filter can be registered with DirectShow for each format.

I was waiting for something like this to show up in the open-source world. Really can't wait to see all the new updates from everyone.

I'm more than ever impressed by what you can achieve with PotPlayer+mVR+LAV+ffdshow. Turns out Ozone5's linear phase EQ latency together with my TV input lag call for -262ms delay in LAV audio for perfect lipsync @24Hz, too good Last edited by leeperry; 18th March 2015 at 04:10. |

so I guess the only thing now missing is a free Dolby Atmos decoder?

I think the important part is getting a renderer that can map arbitrary objects at arbitrary points in a 3D space into (semi-customizable) loudspeaker positions. Unfortunately, that part is beyond what's usually expected of simple software decoders. |

i guess we need new hardware to support the 32 channel HDMI 2.0 setup.
without that we can't even send a decoded DD atmos stream to a over 7.1 setup. i guess this will happen some time in the future this is kinda like room correction software nothing totally new. and headphone DD atmos is something that makes totally sense for a PC too and a full decoded stream is needed for this. so i hope it will be added in the feature. but i guess bitstreaming will be the best way to deal with it. |

LAV Audio request
I'd like more options for sound mixing.
Right now, I can only choose between mono, stereo, 4.0, 5.1, 6.1 and 7.1. I have a 5.1 headphones and some videos come with 5.1 channels, but in most of them I got a bad impression due to voices being too silent in 5.1 mode. So I prefer using stereo output. I'm using KMPlayer and it has an internal "KMP Audio Codec" which has a lot of output options, including "2/0+sub; 2.1 stereo" option. In this mode, the output is stereo but also I really can feel the subwoofer (and I love it). But with LAV Audio (which I'd really like to use as a main option) I can only set sound mixing to Stereo, with no subwoofer output. Setting to 5.1 only gives me an old result which I don't like. tl;dr: I want "2.0+sub" output mode for sound mixing. |

If the surround is to loud (or voices to low), try the to move the slider for surround to the left (less surround) and the slider for the center to the right (more center) in the down-mixing. You'll need to re-adjust the volume on your AMP/headphones after these to compensate. Last edited by Pat357; 20th March 2015 at 01:07. |

Earlier this month, Intel released a new driver that supposedly add video playback of HEVC video format at 4K.
https://downloadcenter.intel.com/dow...7-8-8-1-64-bit I'm not sure if it is software, hybrid or QS? Anyway, I'm unable to test it as the HEVC is greyed out with QS as an option. |

QS does not support this(yet?) DXVAChecker x64 benchmark on the same file shows 40 fps while using 26% of each of CPU kernels on Core i5-4200U. |

The '.1' is the dedicated channel for the subwoofer, but you don't have a subwoofer, so what you're asking for doesn't really make sense. As mentioned, moving the LFE slider up is what you're looking for. It mixes the low frequency content from the subwoofer channel instead of throwing it away. I can hear a little difference, using HD650s and an o2odac, I'm not sure how your setup compares to my headphones, the HD650 is known to have good bass reproduction. Another reason why you might not be hearing a difference is because the content you are watching might not actually contain a lot of LFE content. It really is only noticeable on very low frequencies, even on my surround sound system. The bars in the status tab only show what is being played, so if you have stereo selected only the left and right bars are going to show activity. If you leave it on 5.1/7.1 you will see the LFE bar move, and will also see how infrequent and low amplitude it is.Careful what you set the slider to however, headphones can reproduce the low frequency sounds, but are really bad at doing anything else at the same time. You need a dedicated subwoofer for that. I have my settings set to down mix to stereo and the LFE slider set to 1.58. Experiment as settings vary with different equipment.

and there are a lot of headphones with multiply driver and even a driver for LFE. here an example picture: http://www.tacticalsites.com/~squint...enearphone.jpg 4 is the LFE. these system have a huge problem with bass reproduction when a source is played that's isn't using a LFE channel so a LFE crossover for stereo is a must have for these. a lot of smaller 5.1 or 7.1 system work the same way and get into the same problem without a LFE channel when they are used analog. |

Its far more likely that I will decide not to add any kind of upmixing, rather than also consider adding a cross over. You should find someone that builds you a new audio processing filter, LAV isn't the place where this is really going to happen.

I can clearly hear the difference. I've checked with the same content. Even for stereo-only content, when KMP Audio is set to 2.1 - LFE channel works (as for how it works, I'm not sure - it probably gets added by mixing both channels) and I can feel bass with vibration, with 2.0 - not. With LAV Audio I can only feel that in 5.1 and above. As I already mentioned, moving LFE slider did not do anything when Stereo mode was active. If you are suggesting to use 5.1 mode, I can only repeat that I prefer using 2.0/2.1 over 5.1 right now. LFE in both my 2.1 system and 5.1 headphones can work with both Stereo and 5.1 content. Even if you say there is no 2.1 content, I don't see why there shouldn't be such an option. That's too bad. Thanks for the honest answer. Last edited by Liandri; 23rd March 2015 at 11:27. |

@ nevcairiel - CUDA 7 was released some days ago.
Will it have any reasons like performance, stability or others ones to update it in LAV Video Decoder for NVIDIA CUVID hardware acceleration decoder mode? I remember that CUDA 4.0 was used in LAV CUVID Decoder which was next merged into LAV Video Decoder. On the other hand will The Boost C++ Libraries or similar ones help in performance in LAV Filters, MPC-HC or even madVR? |

LAV doesn't use CUDA, it only uses the video decoder, which is always the same performance.
