Dolby Vision now possible through MP4 Mux.

[PlatypusW]

"Red push" or rather "red blocks" problem still exists
BT2020 flag is different issue

MI:Fallout bath fight scene is the best demo.

Also I would like to suggest Atomic Blonde as test material. For some reasons it has color issues after MakeMKV conversion

Yeah I can still easily see the red blocks on fallout, not sure if that’s the worst it is now - I did have to look closely at times to see it compared to playing it in hdr10.

Will be interesting to see how other devices compare now that at least fire tv (stick) can play back more (converted) titles.

and do we know wether FEL on the shield shows correctly?

Valerian hasnt any color issues
DV also better than HDR in gradients

i agree DV is better.
But is FEL shown correctly so that the improvements in picture compared to MEL is shown?

[lexyz]

Valerian is a good source for compairson
For example this frame around 52:40 mark

Just pay attention to gradiens on wall

Extract hevc streams with ffmpeg: ffmpeg.exe -i X:\BDMV\STREAM\XXXXX.m2ts -map 0:0 -c copy X:\BL.hevc -map 0:1 -c copy X:\EL.hevc

Is it ok to demux m2ts by tsmuxer to avoid ffmpeg?

@ the owners of a Sony x700 player. @ragico(thank's a lot) found a workaround to the bug that forces you to reboot your player after any playback of a dual-layer profile 7 TS file.

play & stop this LG demo and it will somehow reset the player. You have to do that every time you stop playback of a dual-layer TS.
It's not an ideal solution but it's better than having to reboot the player.

the file: https://drive.google.com/file/d/1ZRwhD- ... sp=sharing


Also, I thought the single track FEL (EL+RPU) didn't work on the x700 but apparently some files will work. So I'm now able to compare a single track FEL file to the original disc on the x700.
If the FEL single track files are done properly, I will be able to tell if the Shield can play the FEL metadata or if it's just ignoring it.

btw how do you like this demo on shield in comparison to x700?
Can you notice any odd thing?
Because I clearly see some problems

yep, I see problems too. oversaturated.

In the testing I have done on Shield the colours are off on most DV titles, with the limited testing I have done with Z9X that has red push with converted files also.

[lexyz]

Oversaturated, yes
also:
Few frames flickering in transition from paint to "Storytelling" scene
Artefacts on white "Senses" letters
DV logo flickers in boxer scene

Since this demo is unmodified EL it could be a key to fix Shield problem.
I'm going to send report to Nvidia and suggest all shield owners to the same thing.
Start to play this demo - pause - open Shield Settings - Device Preference - About - Send Feedback to Nvidia
Set topic like: Artifacts DV playback
Comments: Oversaturation, flickering, artifacts on white
Send it

Hello everyone first post here complete newbie. I wanted to try if Dolby Vision playback with Mission Impossible movies is possible with my LG C9

First tried with Ghost Protocol. I followed the instructions on the first post and double checked, the new mp4 is successfully created but it doesn't work. The TV cannot read the file and says it is not supported.

Is there something I did incorrectly or is it because of the file or my TV?

Still can't get it to work even with other m2ts files (tried Black Panther and Justice League). I have Visual Studio 2019 installed and not 2010 though. Would that matter?

First input file is the bigger file, second one is the DV layer, third one is ac3 audio. The rest I copied from OP. Doesn't work. Any suggestions on what I most likely might have missed?

[RESET_9999]

that demo file is FEL though. So they might just say that it's not supposed to be supported in the first place.

Also, the BL is SDR. not sure if that change anything

Should be no difference in what you use to demux (ffmpeg, tsmuxer, eac3to). Although, ffmpeg and eac3to will tell you if there are any imperfections in the original files. It's rare, but if one is encountered, the files will still demux but you might encounter av sync issues upon remuxing.

BL being SDR shouldn't change anything, but this is actually what a properly specced profile 4 video should be (without an HDR BL).

Everything played perfectly. May I ask how did you convert from FEL to MEL?
thank you very much

So these are the steps I take to convert FEL to MEL and remux with TrueHD/Atmos into an MKV:

• Extract hevc streams with ffmpeg: ffmpeg.exe -i X:\BDMV\STREAM\XXXXX.m2ts -map 0:0 -c copy X:\BL.hevc -map 0:1 -c copy X:\EL.hevc

• Feed both hevc files from step 1 into MUX_AND_CONVERT_TO_MEL.bat

• Feed single hevc file from step 2 into DEMUX.bat

• Use latest tsMuxeR nightly, add both hevc files from step 3 into input along with X:\BDMV\STREAM\XXXXX.m2ts from step 1, remove duplicate video tracks and output to ISO

• Use MakeMKV to convert ISO to MKV

These MKVs can then be played back using the modded ExoPlayer and potentially the latest Emby beta (I've not tested Emby).

I've converted and tested a few full length movies and the above method works flawlessly.

Thank you yusesope for all your hard work.

Please, why is it throwing me such a bug in DEMUX.
It stops at the beginning. Thank you very much.
