You accidentally caught the bug of MPC-HC. MPC-HC doesn't create the subkey called "OpenWithProgids" for any of the registered file extensions included in its defaults. Now, those extensions that appear in CCleaner do not have "OpenWithProgids" created by some other program, so CCleaner properly thinks they are unused. MPC-HC needs to create the subkey called "OpenWithProgids" for every file extension is included in its defaults and register itself in both "OpenWithProgids" and "UserChoice" key. Take a look here: the .alac extension appears in CCleaner as unused, while the .3gp it doesn't. Still, even .3gp is not properly registered to MPC-HC since it misses MPC-HC app from subkey "OpenWithProgids"

Trying to get HDR to display on my LG 4k OLED
Hello, I'm experienced with computers but not with HDR. I'm using the latest version of MPC-HC (13) and I'd like know what are the filters and output settings I should use to get true HDR video displaying on my LG OLED55B6P. There's a lot pixelation and banding in the dark areas of the video.
I'm on Win7x64, I have a GTX 1060 and 4.5GHz 2600K, I'm using an HDMI-to-HDMI cable, and I've enabled Deep Color on the TV's HDMI port. These are my Nvidia Settings (if it matters) and the media info for the file I'm playing. |

I'm experiencing some extreme audio distortion/clipping/crackling during loud explosion scenes in the Star Wars films. VLC plays it with no audio problems at all. I've spent over an hour trying to fix it. I've changed virtually every audio setting there is in MPC-HC trying to identify the culprit. No other media I play has this problem. Ever. And I watch a lot of stuff. The films (original trilogy) are just the raw Blu-ray, with DTS-HD MA.
Resetting all settings to default does not resolve the issue. I've tinkered with every conceivable audio setting in MPC-HC. Yes, that includes everything in the audio decoder settings, splitter settings, and audio renderer settings. When I say every setting, I mean it. I've also tinkered with all of VLC's audio settings to see if there is a way to introduce the problem into VLC's playback of the film, which might give an inkling as to what the problem is. No luck. I've searched MPC-HC's bug tracker for various relevant keywords but couldn't find anything. I'm open to any and all suggestions (although please keep in mind the facts I've given you from my troubleshooting attempts. I don't want to hear "Maybe it's your headphones", since it works just fine in VLC,) and I'll gladly give any pertinent information that anyone thinks might help diagnose this. It's driving me crazy. Thanks. |

Did you tried different audio renderers ?
VLC : Directsound by default ? MPC-HC : depends on Output Audio option (Directsound by default) Did you tried the new MPC-HC internal audio renderer ? There is a recommendation with the new audio renderer : volume set to something like 85% in order to prevent distorsion (according to the remark left on the dialog option) |

This isn't a simple matter of clipping. If that was the problem, every loud explosion in every movie I watch would have this problem. This is the only movie that has this problem. I think/thought that the problem has something to do with the DTS S24 7.1 audio on this film, as opposed to the typical 5.1, except I tested multiple other movies with the same DTS S24 7.1 audio and there is no such issue on the other films. |

If the issue disappears with the LFE level set to zero, and reappears as soon as LFE is brought back in, it means the LFE channel in the content you're playing is screwed up. This would not be the first time. One reason VLC might not have this problem is because maybe it discards LFE, or maybe it applies a low-pass filter to it (a similar suggestion was made regarding LAV Audio, but I don't think nevcairiel ever got around to implementing it).

VLC may not support lossless DTS-HD MA decoding, which would give you quite a different result.
An extra special part is that Star Wars uses 6.1 audio, not 5.1 or 7.1, that can cause weirdness in some cases.

When I do that and set LFE to 0.00, the problem is fixed. When I raise the LFE slider, the problem comes back. But somehow I doubt the film was mastered with such glaring LFE problems, would you agree? So where along the chain of audio processing is this problem occurring do you think? nevcariel mentioned the 6.1 audio in Star Wars, and I think he might be on to something (the Star Wars original trilogy are the only movies I have with DTS S24 6.1.) I just don't know enough about the lav filters or MPC-HC to know what to try next... But if Star Wars is basically the only thing I can expect to have this problem with, that isn't so bad I suppose... |

The proper way to deal with this is to lowpass the LFE before downmixing, and filter out the higher frequencies, unfortunately LAV does not support such a functionality (yet).

It definitely sound like a mastering mistake in the LFE channel. It happens occasionally, but the majority of discs are fine, of course.
And yes, such a problem is independent of the channel count, as long as it contains a LFE that is. If you use stereo downmixing, the 6.1 layout wouldn't matter either way, the LAV downmixer can handle that fine.

That's quite a contrived scenario, which is why it only happens rarely. But it can absolutely happen if enough things go wrong simultaneously. Then you're left with a disc that has garbage in the LFE channel. Meanwhile, 99% of the audience won't hear any problem because the LFE channel goes through a lowpass filter on their system (either an actual electronic lowpass filter, or the subwoofer itself), thus masking the issue.

MPC-HC.1.7.10.40.x64.VS2015 doesn't have this issue and MPC-HC.1.7.10.56.x64.VS2015 does. Which means the bug was introduced on Jan 17th 2016. I'm not a dev so I wouldn't know which commit is responsible for this behavior. Could anyone take a look at this? https://github.com/mpc-hc/mpc-hc/com...daf24f7683+244 |
