Dolby Vision now possible through MP4 Mux.

[staknhalo]

BTW I posted about this elsewhere before but can't remember if I posted it here

In case anyone is unaware, install this Win Store plugin: https://www.microsoft.com/en-us/p/app/9 ... verviewtab

It will allow playback of DV 5 & 8 in mp4 container ***NOT MKV CONTAINER*** Windows 10 & 11 ***FOR STORE APPS ONLY SUCH AS MICROSOFT MOVIES & TV APP - NOT WIN32 APPS*** it appears to be player led DV playback entirely within the given app as the entirety of player + display if that makes any sense (HDR must be on before, display won't kick into DV mode at all, the RPU is processed and video output altered within the app window only)

This is separate from having a Dolby Vision certified computer which has DV plugins/files installed through Dolby Access - for all I know that might be for Profile 7/UHD/ FEL playback on a PC or something but don't have it/a DV certified computer so can't test that

Here's the test file quietvoid posted in mp4 format I used to verify

https://mega.nz/file/hDggyRpJ#1GDdqVWh3 ... l5EKAF716U

If you playback the test file in the Microsoft Movies & TV app without the DV plugin installed, you will see no visual shifts when metadata changes in test file, once the DV plugin is installed the DV metadata be applied - VLC Win Store app doesn't work with DV even with this DV plugin installed, old Plex Win Store app does work with DV when that's installed though

This is interesting stuff!

it appears to be DV player led playback entirely within the given app (display won't kick into DV mode, the RPU is processed and video output altered by the given Win Store video-playback app itself)

So would it be fair to say that it's basically automatically converting/downgrading the DV source to SDR/HDR10?

It’s sdr as far as I know.
But better sdr than mad vr from what I’m told.

It puts out HDR brightness/levels (by eye not measurement) when the DV file has an HDR10 base (P8) on my end if that's what you mean? HDR has to be on beforehand on Windows for HDR media/gaming though - even with a TV instead of monitor - it doesn't kick into HDR for you like TVs/TV devices do

that is old news.... the dolby extension will allow DV P5 playback for certified DV PC and will fallback in HDR10 or SDR for the non-certified pc..
I tested it a while ago, both the HDR10 and SDR tonemapping sucks.

Also, you need the HEVC extension which isn't free anymore ( thanks Micro$oft)

But on profile 8 files as confirmed with that test file it's processing and displaying the changes in the DV RPU metadata when playing back - so it's not just 'HDR/SDR only' output on non-certified (mine) PCs, it's the dynamic DV metadata output/DV playback as well for uncertified PCs

wait what ? you are triggering DV from a non-certified DV PC ?

yes my pc is all self built not store bought and not DV certified at all - my PC monitor is HDR10 only not DV (my TV though is)

with that dolby vision windows plugin installed rpu changes in dv8 files which that test file demonstrates - display correctly on my computer/computer monitor and playback with the RPU changes applied/displayed/apparent when watching - uninstall the DV plugin and the video plays back without any changes being apparent even though the text in the test video indicates you should be seeing visual changes

profile 5 files also play back in correct colors for me only when that plugin is installed, in HDR brightness levels (again by eye not measurement) and I'm assuming RPU metadata too like p8 but no p5 file to test for RPU that like as with the p8 test file

I build my PC myself too, not sure what this has to do with this?
You haven't answered my question... Does it trigger DV on your DV TV ?

probably not, so it tonemap DV to HDR10 (or SDR). That's my whole point, the DV to HDR10 (or SDR) tonemapping from the dv extension sucks big time.

I said it does not trigger DV on the TV when hooked right up to the TV it stays in HDR10 - but the RPU dynamic metadata is still displayed and applied (very apparently) all the same on playback when that plugin is installed - and does not when it isn't - that shouldn't be happening if it was only HDR10/SDR playback - so it is playing back/displaying the DV metadata on my uncertified computer, not just only the underlying base video - that's what I was trying to highlight

yeah, we already knew that when the extension was first available months ago.
I said that the DV to HDR10 (or SDR) tonemapping is off (regardless of the DV metadata).... My x700 (newer firestick TV too) can do exactly the same but the tonemapping is right (well except for the raised black levels)

plus the Windows player doesn't support lossless audio anyway and has incorrect static metadata.

It is interpreting the RPU, as you say, but I do still think it's more accurate to describe this as a "DV to SDR/HDR10 conversion". I don't think it's the same as player-led DV. My understanding is that with player-led DV the TV sends parameters about itself to the player (e.g. its brightness capabilities) and the player feeds that into the magic DV algorithms along with the RPU to produce an output signal specifically tuned for that TV.

With this Windows playback, it's not receiving any parameters from the TV/monitor so it must just be interpreting the RPU in a generic way. Perhaps that's useful, but we should be clear that it's not really the full DV experience.

Hi, is it somehow possible to convert profile 8 to profile 5?

I have a file with dvhe.08.06, BL+RPU (and also with HDR10+, which I dont need) and I want to play it on my LG C7.

Thank you very much!

No. Are you sure your TV doesn't support profile 8?
It works on the C8 with ts files.

I've tried and unfortunately it doesn't.
