Dolby Vision Potplayer
Maricel Fergason
According to the reddit post below this should be possible using the latest MPV and GPU Next (It's not actually using Dolby Vision but strips out the per scene meta data and solves the purple tint issue). Id very much like to use this as my Tablet and TV both support DV but my PC does not. This way my plex server only needs one copy of any HDR media.
Unfortunately I'm pretty new to all of this, has anyone tried it with success at the same time as SVP?
It must work. In PotPlayer, leave the video viewer on automatic. Because if you set it to Direct3D11 manually, the image turns purple. Automatically set it to Direct3D9 and you can enjoy the Dolbi Vision effect on your PC. Miles different than a normal bluray movie. More vivid and clear, more realistic. This little add-on I linked to allows it to work in the built-in media player, MPV and PotPlayer under windows 11. You can also install Dolby Vision sound, but it's paid for in the Windows store, so I'm not linking to it, not advertising it, just that you can set up PotPlayer to get the DV sound effect you want. Working in conjunction with SVP, PotPlayer can provide the frame rate to match your monitor, and if you're using an HDR monitor, 10-bit colour depth. (I'm not a professional user and I'm not a tester, I'm just an average IT guy who likes to watch movies with his family in the best picture quality in the evening.)
Hi, great news it works great with MPV
I have a couple of questions though :
1/ Is this real dolby vision decoding and converted on the fly to standard hdr with preserved dynamic metadata ? because the previous solution with madvr wasn't able to decode dolby vision, it was "just" an hdr optimization with frame by frame analysis and static hdr metadata. Also full dolby vision support requires an additional hevc decoder to decode the FEL layer (full enhancement layer) but very few movies carry it.
2/ Is MPC-HC compatible with this solution ? I have read that it requires to use the new libplacebo from ffmpeg
EDIT : I don't understand the use of it. From the reddit post "So the special DV/HDR10+ dynamic scene by scene metadata will get lost/ignored, but i'm not even sure those are used much outside of testfiles?". It is just a fallback solution to avoid purple colors with tone mapping on dolby vision video files that don't carry a HDR10 fallback stream, but the guy from the post may have misunderstood
This problem is not related to the monitor : you didn't get the right version of MPV or didn't configure it correctly
On my side MPC-HC, MPC-BE and VLC render a purplish picture in dolby vision videos that don't have a HDR10/HLG fallback stream.
MPV works though, wether I use a dolby vision display or not (but HDR compatible in both cases).
I have some Movies in dolby vision profile 5 that the Apple tv can play. If i store the file as ts file everything is fine and Infuse trigger DV, but if I store the same files as mkv, infuse Will not trigger DV. Cant infuse play DV files stored in mkv?
Some apps are incorrectly (intentional or not) switching the output mode to DV for profiles other than 5. Infuse does not do this, and always sets the correct mode for the portion of the video which can actually be played.
The Apple TV only supports profile 5. Plex is just forcing the Dolby vision output using only HDR metadata which is not correct. There have already been existing threads about this. You can search for others specific to types and profiles.
Same issue. Its a driver problem. Contacted AMD support (type in Google AMD support contact and you should find it) they confirmed that it is driver issue and are working on a fix, but no ETA do I wouldnt Hope on quick fix.
I have tried everything, it simply won't work. Different cables, different connections, all supported drivers for 7900XTX, extracted old drivers to get only HD audio driver, installed clean windows 11 on a second drive.
I can choose Dolby Atmos for Home Theater and it won't work. Using the Dolby Atmos for Headphones does work and when I play one of the sample videos in the Dolby Access app it does not give me the warning that I'm not using Dolby Atmos and my soundbar shows that what is playing is in Dolby Atmos.
But I have to say, it is possible to do it but if you click on "configure", you can see, it is only stereo , so I have to investigate if surround works correctly with this option. As I mentioned above I will definitely share my findings, anyway thank you very much for your findings!
So Dolby Atmos for Headphones is not working, also the output signal/format is not Dolby Atmos, at least according to the soundbar/tv.
Also, I can confirm that during my playing, it is just stereo. So I switched back to 5.1 surround.
Thank you for your response.
Thank you for providing the details
The issue that you are experiencing is reported to our driver team.
Currently, our engineering team is looking into the issue please wait for future driver updates.
Thanks for contacting AMD
I just got a 6800XT, and same issue as everyone here. I can play the Atmos demo from windows and the AVR switches to ATMOS, so I'm not sure what's really going on?
I was with Nvidia 2070S and 0 issues, and now this comes up with AMD. ffs.
The problem you face is, your CONTENT is NOT DOLBY ATMOS. DOLBY ATMOS requires 9-13 channels bluray AC3 audio lossless AC3 format.. so maybe just over or equal to 660kilobits for 5.1 for older DVD AC3 might need a higher bit rate by a third or more again per channel? i dunno a netflix DDplus 7.1 stream uses about the same really. the ATMOS hardware speaker systems chip and technology will then give you output for height speakers at 19-21 channels of discrete separate channels and specializes in ceiling filling the room with high frequencies for bullet whizz surround sound noises in war movies or bird calls in the forest to sound more positional.
I suggest you try the following option A and option B. KODI.TV website and media player app. and or DAUM potplayer app mediaplayer. Then get some DOLBYVISION and DOLBYATMOS TV cinema trailer/preview demo clips in highest quality. search some 8k TV demos with DOLBY ATMOS. then play back with a configured DAUM POT PLAYER using the additional codecs installed during installer and use maybe WASAPI EXCLUSIVE MODE.. test with exclusive mode disabled too and HDMI/SPDIF enabled passthrough. You will want to select your RENDERER and your OUTPUT renderer WASAPI both i suspect but directx/directsound may work better depending on a few factors. you could do a similar setup with kodi but the DAUM has a AC3 live rencoding output you can test first and use the hardware acceleration and D3D 11 renderer and FFDshow to play it back. It should output just fine assuming your TV input has an 8K HDMI cable 2.1 and HDMI 2.1 ARC to your ATMOS RECEIVER. The dolby access headphones app is so your multichannel blurays will more correctly DOWNMIX the ATMOS tracks to stereo, or can play back stereo mp3's to your receiver in a way that it sounds less stereo and more all speakers but isnt ideal.
nvidia and intel are fake and not computers not maths.. the reason they sort of pretend to work with dolby audio is your HARDWARE sound receiver from denon or pioneer or onkyo whoever it copies it into the AV receiver and the receiver hardware chip does it.. literally mount it in linux drag and drop files into it. IS HOW ITS **bleep**ING SUPPOSED TO WORK! when i find the **bleep** faces that are **bleep**ing with our graphics cards realtime hardware encoding/decoding.. argh.. because fake hardware like nvidia and intel cant even use audio at all like the same REALTEK audio chip from the AMD card.. INSIDE the nvidia card.. doesnt have maths doesnt have a computer isnt 0 latency.. its audio sounds like tin can cheap $2 USB stick mp3 player off ebay 4GB. Because thats basically what your intel CPU and nvidia GPU are. If you ever buy real AMD from the AMD store.. and manage to configure it and USE THE HARDWARE.. well you're in for a treat. But yeah simply using a printer or a sound system with DOLBY decoder hardware.. means nvidia and intel drag and drop the file into someone elses hardware that physically exists and isnt fake software bull**bleep** turds cheap trash. So if you mistakenly thought your nvidia not hardware before worked.. well it wasnt. your SOUND SYSTEM hardware does.
Well, you can be on your high horse how much as you want, but I'm playing bluray 4k versions of LOTR, and those are indeed ATMOS TrueHD of about 120GB each. Kodi logs state that TRUEHD isn't supported by the hardware trying to decode it (AMD 6800XT on latest drivers)
Having said that, rolling back audio drivers to the ones from 21.5.1 seems to fix the issue right away, so I have to have a mix of video with the latest update, but Audio drivers from a year ago.
Hope AMD fixes this crap ASAP.
OOOH if you are playing back with a bluray CD ROM disc drive for PC ROM or writer or using an ISO image file of it.. you MUST purchase a bluray playback devices and enable HDCP and ensure that HDCP and HDMI have certain prerequisites in security. You NEED TO COPY IN A SPECIFIC SECURITY DLL that can only be purchased to playback and passthrough in higher quality for bluray disc format. its hollywood security. CYBERLINK powerDVD or similar need some DLL file name that comes with a purchase unlock of it and to use DRM rights management such as googlewidevine and that otherone i forget .. in your OS and browser.. you can check for support maybe in edge://flags in your edge browser.
