What Plex Client version was this on? I can't get Plex to output lossless audio on my Ugoos AM6B Plus.
no particular version. I was able to make it work about 3-4 times and it just seem to work randomly.
Do you still have an Ugoos AM6B Plus? I am looking for a Kodi build that processes the Full Enhancement Layer. I have tried several different builds. Only the modified ExoPlayer APK processes the FEL, but it stutters so much that it isn't really watchable. Do you know a Kodi build that definitely processes the FEL?

nop, I sold my ugoos a long time ago. I was using the Kodinerds built and it processed the FEL but there was micro stuttering and sometimes the movie would just freeze.

In my opinion, you are wasting your time/money with this device. If you want stable FEL playback get the Sony x700 or x800m2.

Oh, I see. It's so annoying, because I feel so close to achieving complete Dolby Vision playback. Plex can process the FEL and play it smoothly, but it doesn't have lossless audio on this device. As for Kodi, I have Dolby Vision playing smoothly with lossless audio on Fandango's build, just without the FEL. If only Plex got to supporting lossless audio on this device; then this would finally provide reliable playback for everything.

Hello,

I'm new to the forum and i'm trying to use the script but getting a lot of path errors and LAV Filter can't be loaded issues.

I'm using Windows 11 Pro.

This are the errors i currently get when trying to create DoVi from HDR10.

I tried option 4-4
And also option 7-1-6

Always same errors with paths and LAV Filter as follows:

Code: Select all

F:\TEMP\THD.mkv: No such file or directory
Error: Unknown mode 'F:\TEMP\_AC3.mkv'.
SMPTE ST 2086
Connecting LAV Splitter Source to LAV Video Decoder failed.
Parsing madVR measurement file...
Error: System can't find the file specified. (os error 2)
Also other errors:

Code: Select all

a02 Processed audio track: max 24 bits, average 19 bits, most common 16 bits.
Video track 1 contains 1303 frames.
eac3to processing took 2 seconds.

Hello, i installed the folder into the C:\ instead. It was on F drive before.

Now it worked, somehow it had issues with other driver rather than system drive.

I have a question, is there any way to make the resulting MKV file to show the mastering display luminance/MaxFALL/MaxCLL and color mastering metadata , like when watching with MadVR and you hit Ctrl-F to show info? now it shows only BT. 2020 primaries and BT. 2020 color, nothing else there. It should show the nits mastering followed by the color mastering. Like: 1000 nits HDR - BT. 2020 > DCI-P3 .....

I'm not sure I understand but, the script cannot change/remove the static HDR10 metadata of the resulting MKV.

Yes, it's just the Metadata for the video track. Which in this case would be inside the DV Profile 8.

This is an example so you can understand.

Spider-Man NWH Dolby Vision Profile 8 - MadVR On-Screen INFO:

It shows HDR 9978 nits, since the metadata is properly injected:

You see the Mastering Display numbers at the bottom.

But this is how it ends up when using the Script ( From HDR10 video, which includes this metadata information, but it goes away in the resulting MKV with DV Profile 8 ) :

You can check at the bottom the Mastering Display information metadata is lost.

I've always did this by additional commands to the MKVToolNixGUI. Though if i add these additional commands when muxing the DV Profile 8, it will show duplicate HDR10 metadata.

Like for example MediaInfo shows HDR10/HDR10

And in the detailed information it shows the added metadata for Mastering Display Nits/MaxFall/MaxCLL and Color "P3" though in MadVR won't show up.

Looks like this works kinda different when doing Dolby Vision muxing. It may be added in a future update for the muxing tools used.

The script will not change/remove the original static hdr10. Custom metadata with mkvmerge cli is another story and I don't really care about it because I use TS container and those custom metadata are lost anyway when muxed in tsmuxer (and probably in the mp4muxer too) and there's nothing I can do about it. Plus it doesnt matter in DV.

my SM no way home using the script... clearly your picture isn't right .. even chroma type 2 is different... level 6.1 ? whatever you did to split that file broke it.

I convert all the MEL movie to P8 so i can watch it anywhere ( TV internal player included). P7 is only useful for FEL.

Q, has there been any work done for colorspace conversion for DV profile 5 to HDR10 or SDR? There's plenty of work on tonemapping HDR10 to SDR, but wondering about for DV content on non DV devices.
Of course, it has been supported in libplacebo and mpv for a while now.
Also, Jellyfin has beta support for real time transcoding: https://www.reddit.com/r/jellyfin/comme ... is_coming/
how well does this work on linux? i.e. would the same gemini lake CPUs that can tonemap HDR10 to SDR also be able to handle DV to SDR? I'm also wondering about DV to HDR10, the link only says sdr)

Is there some trick to enabling lossless audio in Plex on the Ugoos AM6B Plus? Lossless audio works in Kodi. Oddly, the 32-bit Kodinerds build seems to discard the Full Enhancement Layer in Dolby Vision, even though Plex plays it perfectly. If I can just get lossless audio working in Plex, I will finally achieve full Dolby Vision (FEL) playback.
what plays the FEL? All I've heard is things that "work" with FEL play the MEL and ignore the FEL. so they play, but they don't play the full dolby vision experience. has this actually changed?
