Delay value higher than 7487 behavior
See how MPC-HC starts messing up with how it displays the ac3 specs with a delay value higher than 7487. Any idea what could cause this?
No delay: A: French [fre] (ac3, 48000 Hz, stereo, 192 kb/s)[default] Delay value of 7487: A: French [fre] (ac3, 48000 Hz, stereo, 192 kb/s)[default] Delay value of 7488: A: French [fre] (ac3, 48000 Hz, 2 channels)[default] Last edited by 2-perf; 10th November 2019 at 14:47. |

Audio and video are supposed to start near each other, if the difference is too large it won't find an audio packet to analyze it.

There is a mpv based mpc clone but it might be unmaintained, have you tried mpv or vlc?

Question - is it a bug or simply a case of the feature not being implemented that h.264 video streams flagged as "fullrange" (0-255) color still display as "limitedrange" (16-235)? Specifically when flagged using this utility:
https://forum.doom9.org/showthread.php?t=152419 By comparison, both mpv and VirtualDub2 seem to handle the "fullrange" flag correctly. As an example, here's a ~3 second video clip of a fullrange-flagged MP4: https://web.archive.org/web/20191026...XmH_sample.mp4 And for reference, here's an animated PNG created from screenshots exported from VirtualDub2 showing the difference between fullrange and limitedrange on the above sample MP4 (make sure you're using a browser that support APNG).

I have a theoretical question.
Does anyone know if you could feed a live HDMI capture device into MPC-HC? Mainly I would want to open an HDMI capture device in MPC-HC which then feeds it through to madVR. Furthermore does throwing in 4K HDR HDMI capture to the mix make it any more difficult to achieve this? With something like this: https://www.elgato.com/en/gaming/game-capture-4k60pro |

sure you can do that you just need an directshow filter that can work with that your capture card but you are missing something here.
you will need an card that is HDCP confirm or any media that needs it will not work and even if you want a card that doesn't need HDCP you should get a card that is lossless and well these are 140 mbit encoding card that not even close to a lossless card they exist cost was about a grand. btw the HDCP part is not fixable is not allowed to sell capture cards that decrypt the input signal to a video renderer that is not HDCP confirm. this card can do "everything" except decryption: Magewell Pro Capture HDMI 4K Plus LT well you need 4x lanes of PCIe 2.0 most board have a slot for this but not all and it has directshow support out of the box. ahh yeah audio should be PCM... |

Thanks, I didn't realize that not all these HDMI cards did lossless.
I wasn't going to bring up HDCP but I appreciate your concern. The way around HDCP however is to use an HDFury Integral to convert HDCP 2.2 to HDCP 1.4, then feed that into a grey market HDMI switch that strips the HDCP 1.4. After that the HDMI capture card should accept it. You said the audio is PCM, but would bit-stream work? Last edited by SirMaster; 15th November 2019 at 06:34. |

i doubt bit streaming will it states IEC60958 but without tring who knows it has 3 different API is supports and there is no word of p010 atleast for directshow use and using HDMI 1.4 makes it impossible to use a lossless pipeline with 4:2:0 content.
while directshow is listed that doesn't mean you don't need an extra filter to get it into mpc-hc. i guess it is possible to use youtubeDL to pipe it in mpc-hc if you can't write dshow filter you should give up on this. |

and how is that any useful for someone that want's to use lossless UHD HDR?
at one point they are going to be cheaper much cheaper. i can find a UHD 30 lossless capture card nearly instantly for half a grand it's just a matter of time before they are priced in the 200 region. try your luck you may even find one on ali express already. the number of lossless 1080p60 card should be quite a list. |

Am I being dumb, or is MPC-HC's built-in youtube-dl selecting AVC even when "YDLVideoFormat" is set to either '3' or '4' for the following video?

Which is just weird since the VP9 encodes exist and can be downloaded via stand-alone youtube-dl:
