DolbyVision encode error: ": Dolby Vision requires VBV settings to enable HRD"
Hi

You need to set --vbv-bufsize and --vbv-maxrate to the appropriate values. I don't know what those would be for your scenario. It's not clear what you're doing here; high tier plus 10 second GOP isn't supported by anything I can think.

What HTPC can actually do the Dolby Vision part of this? AFAIK Dolby Vision output (Profile 5 or 8.1) from PC isn't possible yet. I could be wrong tho
You sure you're not just seeing the HDR10 base layer from the Profile 8.1 stream? |

It probably would play it. The main thing I noticed yesterday is that mkv container doesn't work with DV, so it's not going to work anyway and I just encode HDR 10 or 10+ as it seems, whatever the fallback option is. Looks like I gotta redo those titles once it becomes a workable option |

The problem is that yes, mkv doesn't support Dolby Vision, but also that the only way for consumers to play it back outside of the UHD, AFAIK is the old, discontinued Oppo UHD Player. You could rip the disc and play it back via network, but it had to be an exact image of the disc. As for muxing into a .TS or an mp4, there are issues there as well.
"Single track DV plays fine on LG TVs and Apple TV 4K, but UHD discs are dual track and can ONLY be played on the discontinued Oppo player. It’s EXTREMELY unlikely there will ever be a software solution to play dual track DV, so the big open question is can someone get ahold of software to change dual-track to single track. So far no luck. Also the DV layer needs to be embedded using special software and hardware which is locked down and not available to the public." <--lifted from reddit There is currently also no software players that support Dolby Vision on PC. Yes you can play games that are in Dolby Vision, but that's because it's baked into the game with all the coding. Let's also not forget that Windows still can't do basic HDR properly. Even Kodi just recently got Dolby Vision working on Netflix, but not with anything else. |

Basically your Dolby Encodes are the equivalent of making mini-disc copies of your stuff. The moment your TV dies, or a new firmware update breaks the feature, your encodes will stop working as they aren't standard. It sucks as Dolby Vision is far superior to HDR. |

To get playback on other devices (Apple TV, Chromecast, Android TV, Amazon Fire TV, etc) you generally have to segment the content into fragmented mp4 / cmaf and use an HLS playlist or DASH manifest to serve it up from a web server using the native player of the device.
Dolby Vision is widely supported these days, but generally only via DASH / HLS in the native players / a native app on these devices. |
