I don’t get flashes with P7 only P5 and P8 RPU’s seem to work on the Amlogic S905Y4 sadly.RESET_9999 wrote: ↑Thu Feb 03, 2022 9:10 pm
If you only see a blank red picture only, it means FEL is not processed. I'll try to take a picture when I get home.
Do you see the flashes though?

yep, unfortunately, it sounds like that device is doing fake DV with P7.mtotheb wrote: ↑Thu Feb 03, 2022 9:17 pmI don’t get flashes with P7 only P5 and P8 RPU’s seem to work on the Amlogic S905Y4 sadly.RESET_9999 wrote: ↑Thu Feb 03, 2022 9:10 pm

Here's what the FEL test looks like when FEL and RPU are 'working' as intended

Re: Dolby Vision now possible through MP4 Mux.
thank's @staknhalo
the FEL and RPU test files can also be used to find out if your device uses the L5 active area metadata in the RPU.
if it uses L5, there will be black bars otherwise it will be fullscreen.
C8 internal player = black bars
Shield = full screen
x700 = full screen

Please tell me the way convert P5 to P8 of this file.

Re: Dolby Vision now possible through MP4 Mux.
RESET_9999 can you link me the files that i can test to see if dolby vision is correctly displayed?
I’have buy a minix u22 that must support dolby vision, i have try several bluray with DV ( converted to .ts format ) and all seem to play correctly…
Sorry for my english, i’m italian.
Ah, another question how i can convert a DTS audio bluray traks to AC3 5.1 ( or best ) , because my sound bar ( SONOS ARC ) not support DTS .

Re: Dolby Vision now possible through MP4 Mux.
the link is in my signature.
I recommend converting to DD+ 1536kbps with ffmpeg:
Code: Select all
ffmpeg.exe -i input.mkv -map 0:1 -c:a eac3 -b:a 1536k -c:s copy output.mkv

But i not have the mkv file.I can demux m2ts file from bluray to obtain DTS audio track with TS MUXER, and then?RESET_9999 wrote: ↑Fri Feb 04, 2022 3:05 pmthe link is in my signature.

Re: Dolby Vision now possible through MP4 Mux.
Tested “RPU-FEL Test DT DL p7” .mp4 and .ts, both show same images ( as your post ), but .mp4 stuck at 0,20” while .ts play entitely….so, DV work?

Re: Dolby Vision now possible through MP4 Mux.
just change the input extension to whatever your source is.
Code: Select all
ffmpeg.exe -i input.m2ts -map 0:1 -c:a eac3 -b:a 1536k -c:s copy output.mkv
0 being video 1
1 being video 2
2 being english audio
You're supposed to see flashes if the rpu is used, and a video on top of the red image if fel is used...

Re: Dolby Vision now possible through MP4 Mux.
You really just want the DTS-HD bitstream passed through, not decoded, right?
Seems likely that the Amlogic DTS-HD decoder takes DTS-HD input but only decodes the lossy DTS core.
That's how, e.g., Plex's DCA decoder works.
Otherwise they would need to be paying for a hardware decoder license.
But ultimately, you don't want it decoded by the stick, you want it passed through for the soundbar to decode.
Since your soundbar is reporting DTS, seems like the Amlogic is decoding and re-encoding to DTS at worst, or only the DTS core is getting pass through at best.
I assume you have this plugged into your LG B1 and it's passing audio to the soundbar via eARC? Does the B1 pass lossless audio from an HDMI input out via eARC?
On the Sony A80J/A90J, it supports lossless audio over eARC, but only when played back via internal apps. The Sony OLEDs won't take lossless audio from one HDMI port and pass it out through to the eARC HDMI input. TrueHD audio doesn't play at all and DTS-HD only passes through the DTS core or doesn't play, either. So that may be what's happening here if the B1 behaves the same way.

Re: Dolby Vision now possible through MP4 Mux.
You can extract the values from the original RPU and see what it's using.
Or maybe quiet_void or RESET_9999 can confirm what happens if you specify 0 for MaxCLL and MaxFALL when editing the L6 data. Some of RESET_9999's tutorial videos show leaving those values at 0 when editing the L6 data with dovi_tool.
Code: Select all
dovi_tool extract-rpu video.hevc
dovi_tool info -i RPU.bin -f 0
Then you can follow the remaining steps to edit and inject the RPU from my earlier post.

Re: Dolby Vision now possible through MP4 Mux.
yeah , I don't edit the L6 metadata when I go from p5 to p8. (unless the metadata is invalid like some of the iTunes web-dl)

That would be great!!nekno wrote: ↑Mon Jan 31, 2022 1:36 amI don't know about the other players, but the X700 wouldn't play P8 in BDMV format in my testing. It locked up the player with a black screen.jayper wrote: ↑Sun Jan 30, 2022 7:53 pmIs it possible to create BDMV folders or ISO files with Dolby Vision Profile 8 files and have them properly play back on a UHD Disc player, like an Oppo? Or is profile 8 not supported by the BD player spec?
I am asking, as I only have an Nvidia Shield, x700 and an Oppo 203 clone, and from what I have gathered, the Shield does not have accurate coloring for Profile 8 DV.
The only DV profile supported by UHD BD is P7, with either FEL or MEL.
The best combo of DV P8 + lossless audio + subtitles + FF/RW support on the X700 is to use tsMuxer to create m2ts files.
I also asked about this a week or so back, and to use BDMV format, we'd need a legitimate EL with the same frame types in the same order as each frame in the BL in order to carry the RPU. P7 doesn't support BL+RPU, it needs BL+EL+RPU.
I haven't seen anyone successfully accomplish that yet.
quietvoid mentioned he might think about adding support for generating an MEL to dovi_tool, which would make P8 or P5 conversions to P7 possible.

That should show the MaxCLL and MaxFALL values already in use. Copy those to your L6.json file, and just set the min display luminance value to 50 and the max display luminance value to 1000 to correct those values.Code: Select all
