Dolby Vision now possible through MP4 Mux.

For us lazy people:
UsEac3To, GUI to eac3to, has added small GUI support for thdmerge with truncating option. THD and AC3 must have same name.

Created some powershell scripts to handle MKV to MP4 with dolby vision. Hoping others can get some value out of them.

Why Audio offset in your script is it 1100ms?
What's wrong with 0ms?

I've got Sony X700 but it cannot play my BDMVs from 4k UHDs. I googled it and found this forum. If I understood correctly, X700 cannot read BDMVs ripped from discs. I should create another BDMV folder using tsMuxeR, am I right? Can someone please explain the workflow how I am supposed to do that. A total newbie here.
Thanks

Hi i have something to share

I am owner of LG CX and C8 models and also nvidia shield.
I made numerous conversions to make sure what is best, i found that for those LG models most reliable is mp4, m2ts is somewhat ok but for me had seeking issues at least with emby. I have found its best to convert to proper mp4 and keep Atmos and other tracks for safekeeping to be able to remux to mkv in future once at least nvidia shield plays correctly (it does not due to colors issues etc). I have found for best results is to play mp4 directly on Emby app on LG

I have created bash script that automates authoring and conversion of different Dolby Vision mkvs to mp4 that will work on above LG models without issues, so far i have converted around 30 releases no issues to the point i automated workflow

So my tool converts whatever mkv you throw at it to mp4 with DV4,5 or 8 with EAC3 audio and keeps original truehd atmos etc alongside for future, i have tested and remuxing with mkvtoolnix makes it playable with atmos again on nvidia shield no issues.

It automates ffmpeg dovi_tool and mp4box workflow and try to use as little drive space as possible thanks to linux pipes. I have it running on my NAS and is chugging along fine

Take a look comment, or contribute

Tell me how to setup and run your script.
I've download it to my PC, but I cannot run it.

I believe it is still not possible, at least with my B1, so C1/CX will 99% be the same. LG just seems to downgrade their TVs (first ditch DTS, then P7 DV).

@gacopl would it be possible for you to make this script for windows powershell/cmd? I was looking for just that, as I use plex on LG B1/C1 and other devices, so AC3/EAC3 is a must for direct stream with subtitles (LG).

Guys i have run into a problem running this script.

I tried to troubleshoot it myself but with no luck. Anyone run into this issue as well ?
Trying to convert Profile 7 BL_RPU_EL single track mkv to mp4

I'm not sure if anyone noticed but TSMuxer was recently updated to properly handle TrueHD audio now. So no need to demux or convert anymore.

@RESET_9999 I have question regarding playing DTDL M2TS file which triggers Dv while playing through usb from x800m2 where the same file plays as HDR through network from my NAS , is there any change need to be done ?

Sounds like your M2ts is an original file from a bluray disc.
You have to remux your bluray disc with tsmuxer otherwise you get fake DV via USB and HDR10 via the network.

Ok , will try to do that . If possible can you reshare your dovi tool ? If its still under developemnt , can understand!

@RESET_9999 Thank you for the comprehensive script. I have a question regarding MaxCLL and MaxFALL values assigned to the RPU, when working from a madVR HDR measurement file. Should the MaxCLL and MaxFALL values be pulled from the measurement file or manually assigned? I have some HDR10 files that do not list MaxCLL or MaxFALL values, when viewing with MediaInfo. I'm in the habit of leaving these values set to "0" and allowing them to be set from the measurement file.

I asking because the "MODE.madVR.TO.DoVi.workflow.8" option seems to be overriding them, in the case when they are set to "0". I modified the script a bit by removing the L6 "editor" lines and injected the original "%output_path%rpu.bin" created. This allowed the MaxCLL and MaxFALL values to be from the measurement file.

Is this the expected behavior or should they be set to "0"?

If it worked for you, can you please share how to use tsmuxer. I also have X800M2 and have a bunch of BDMVs but do not know how to use tsmuxer.
Thanks
