I guess we could encode a 4h silent ac3 core and use it for any movie (in case the mkv doesnt have an AC3 compatibility track)
That would be really cool!
And waht was tgat fix.ts file?

Yes, I'd think so too. Thinking of this new option, any other track that's on the disc? For example, a commentary track you really like?

You used to have a link listed in your signature to a file that would fix an issue during playback where the device would lock up.

thats what i thought but wasnt sure.
The file is still available in the DoVi test files link in my signature.
@chros, that file will unlock the oppo/x700 for when you play 2 DT-DL TS video in a row.

I couldnt make a 32kbps track and thdmerge would not process a 40kbps track but it seems to work at 64kbps. Hopefully, the track still play on my x800m2
here's 4h of silent 5.1 AC3 audio at 64kbps.

EDIT: it works on the x800m2 !!!!!

I tried to add 2ch 32kbps AC3 with eac3to. No dice, got error.
Good to know silent core is working on the Sony.
Thanks for the file

Most handy

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.

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).
