It's simply because LPCM uses different levels. It has always been the case.

Its just how receivers work. They have different reference levels for HDMI input and decoding on their own. Maybe its intentional so that compressed formats are perceived "better" (since for most people louder is better), but who knows.

MPLS angles support

I've just purchased a bunch of GKIDS BD's that uses the MPLS angle feature to differentiate between credit sequences. As of now I'm forced to watch them with English credits, but I'd strongly prefer the original Japanese credits. Very frustrating. I've tried using the modded mpc-hc with dslibbluray (with madvr, navigating blindly through the BD menu), but the subtitles seems to have a life of their own. They don't follow the timecode. I've tried both XYsub and the built in subs renderer. I've also tried using the seamless playback function in Potplayer by adding each corresponding m2ts file the playlist, but with this method there's loads of audio glitches/skippings and the audio always gets out of sync, regardless of which audio decoder/renderer I use. Is there any other method I can use if madvr is mandatory? Ripping is not an option. |

And not to mention that e.g. dts-hd bitstream has metadata that the receiver can process differently than a raw stream.

Whether it's additional metadata or whether it's just something my AVR does when processing bitstreamed formats, it definitely sounds different. Not even just a case of lower volume. Turning the volume up does not match the sound 'impact' of bitstreaming. It sounds fuller, a more natural 'enveloping surround' sound, with better bass. LPCM in comparison just sounds like 7 individual channels of audio, plus much lower sub output. Poor explanation I know, and I know some might be sceptical lol. Anyway, nothing to do with LAV, definitely my receiver.

Do you have any other filter in the audio chain than splitter/decoder/renderer? If you want I can post my mpc-be related config options. Quote:
But as I mentioned, using wasapi exclusive mode (I think the shared mode is also fine) in internal filters in mpc* solved my issue.

Support request - #29
Problem with "LAV Splitter Source", it can't grab second wmv3 video stream from this 3D-video file example:

Only MKV 3D files or Blu-ray 3D SSIF streams are supported. No plans for any other files at this time.

Does this mean that a player such as MPC-BE can play a 3D ISO once mounted?

Problems with 3D MVC playback
When I try to play a 3D Bluray, I just get a black screen in madVR.
My current setup is Windows 10 FCU, Radeon Rx 460, Intel 6700T Skylake, Latest LAVFilters nightly (0.70.2-83), MPC-BE 1.5.2.3285 nightly, madVR 0.92.10. I included the MVC download, when I installed LAVFilters. When I try to play a 3D Bluray, madVR goes into 3D mode, and opening the stats confirm that it is in 3D mode, and the audo starts playing. But I just get a blank screen, and looking in the stats screen, I can see that the decoder queue does not fill up, and stays at 1-1/16, and after a little while, MPC-BE freezes and needs to be killed from the task manager. Also, I can see that the CPU usage is stuck at 25% (2 threads running at 100%). However, if I pause the video and point at the seek-bar getting the small preview window to show, then that one actually shows video (It shows 2 pictures in OU-mode, but it at least shows something). If I look into the LAVFilters video status window, I can see that the active decoder is "msdk mvc". Since the decoder queue in madVR does not fill up, I am guessing that the problem lies in LAVFilters, hence the reason I am asking here. Please forgive me, if this is not the case. If I reencode the video using FRIM, then the video works fine, so at least I know that the Intel SDK is working properly. Any help is apreciated. If you need any additional info, please don't hesitate to ask, and I will answer as good as I can. |

hi, it can be really hard to track down issues with 3d playback as there can be lots of variables, i currently have an AMD RX 550 but I had an RX480 before that and it worked perfectly.
1. Install MPC-HC (easiest to configure for testing) 2. add the latest LAV filters as external filters - 1x audio 1x video 2x splitter - set to prefer 3. untick internal source and transform filters 4. set madvr back to defaults, (you can dial in your own preferences for scaling etc once its working again) 5. turn on all stereo 3d options in MADVR - (4 ticks) 6. Turn on FSE (full screen exclusive mode) - this is always required for AMD card at the moment, not necessarily required for NVIDIA cards 7. AMD cards can already do 23.976 so no need to faff about with custom res but add 1080p23 to display modes for now on its own, this is assuming the 3D movie is a 3D MKV RIP at 23.976 8. Power cycle you TV and receiver, sometimes mine stops working, about once a month and i have to power cycle my TV. 9. Set MPC to open in full screen but make sure autochange monitor mode is unticked. 10. make sure you set the RX460 as you renderer in LAV filters (external) try again.

Please refrain from making generic statements. There are very few things that are true for every one, even on the same platform (same OS version same GPU family) due to the many parameters involved in a HTPC.

This seems to change depending on which forum you are on and who you are talking too but i have amended my statement for now.
Has anyone ever given a reason why some cards dont work and so do and which ones, is it a driver issue or setup?, certainly when I was asking this question on the MADVR forum several people where quite clear in stating I didnt need FSE for 3D MVC, I disputed that until I tried it and it worked without FSE on my 1050. |

I don't know why it works for some and not for others. I haven't seen a trend re GPUs or OSes. I just know that 3D doesn't work for me and others without FSE on nVidia.

Well, its hard to keep track and make sense of what people say, often answers come out of context out of place or a few pages later and they get missed, also , everyone is always contracting each other, I said the same thing as you and as soon as I did a load of people came back saying FSE wasnt required for NVIDIA cards. Then you alone came back saying it was, I went with what seemed to be the majority and my own experience.
Sometimes you can really only rely on your own experience, especially when you are trying to advise someone with a similar setup to yourself. |

More experienced people in the thread, such as Madshi or Nevcairiel, can make general statements because they infer their advice from all the personal experiences they have collected in the past, which adds to their vast knowledge and expertise in the tools they have created. If you don't pay attention, don't remember, please refrain from giving unsolicited advice on all matters. Leave other more experienced people offer their advice first, and learn from it. You don't need to comment on everything. It adds noise and confusion. There are only limited areas of discussions where I think I might be able to help. Half the time, I'm wrong or have forgotten something. So I try to post less to help more, and I would say I am significantly more experienced than you.

Thanks for the advice, but the only thing on your list that I haven't tried is the FSE part, but I am not sure that is the problem.
It goes fine into 3D mode. I have to use the glasses to see the stats, and they pop out at me. The problem is that the decoder queue does not fill, and it is stuck on 1. If it matters, the computer is connected to an Integral, which is connected to my Denon AVR, which is in turn connected to my Optoma 1080p projector. |
