@RESET_9999

Yeah, now it created an mp4 and the first time, the LG play it in DV!

But still some things.

Is it possible to select the tracks which should be muxed?

There are 2 audiotracks, only the eng was muxed, not the ger.

The correct german forced sub was muxed (luck?) and the TV shows it, but in mediainfo the "forced flag" is set to no. Anyway it's working, so if it's working on every file correctly, thats not a problem.

The ts / m2ts file that tsmuxer creates is not working on the 2016 OLED TV.(When I drag the input mkv file into it and let it mux)

In tsmuxer you can't set a forced flag to subs and converts srt to sub.

If you demux the mkv and you select 7-1-1, you can input any audio (up to 2) and any SRT (up to 2). Just make sure your hevc file doesn't have the same filename/path as the original MKV
for the other mp4muxer workflows, you have to edit the bat file with notepad and set the desired language. I didn't really test that though.

I could be wrong but I don't think you can set a forced flag with the mp4muxer/mp4box

I see. You might run into the green screen issue with some DV file on 2016 lg oled TVs

I edit the language and it works for the audio.
Thank you.

How can I pause the script after demuxing and before muxing?
For example I can editing the subtitles before muxing.

The tags (if it's german or englisch audio "eng" "deu" ect.) of the video / audio / subtitle doesn't work but this is wayne :mrgreen:

And the TV is not allowing to REW or FF the mp4 file. It's OK, because I can skip with the arrows.

I don't have this green screen but it says, Can'T play file. Or it plays the HDR10 only.

I think

Code: Select all

mp4box -add sub.srt:txtflags=0xC0000000
can set the forced tag for sub in mp4.

If it's the same green screen issue caused by additional "reshaping data" like on Apple, just use dovi_tool to "remove_mapping".

yea maybe it's the same issue. I remember this was reported in the very early days of the mp4muxer when only dual-layer dolby vision rip was possible.
IIRC it was all the 4000nits P3 BL that had the issue.

Ok, can I manual muxing after use your script for demuxing?

What's the muxing script with
1 video stream DV 08.06
1 eac3 or ac3 audio stream
1 srt forced flag subtitle
looks like?

mp4box -add dv.hevc -add audio.ec3:lang=eng -add sub.srt:lang=ger:txtflags=0xC0000000 -new p5.dvh1.mp4
or if you want proper P8.1

Code: Select all

mp4box -add dv.hevc:dv-profile=8.1 -add audio.ec3:lang=eng -add sub.srt:lang=ger:txtflags=0xC0000000 -new p81.hvc1.mp4
I don't know the exact short tag for german.
If sub and audio are marked with same language tag, sub will default show up in most devices even without the 'forced' flag. So if you just want the sub to default show up, you can deliberately mark it English. I mark all my Chinese sub as eng, lol.

With this script, the TV does not play Dolby Vision, only HDR.
Mediainfo shows three times "HDR10".

Btw what does "proper" mean?

MP4 is a horrible Container. I recommend for fun with DV files a Shield Pro 2019 Media Player (or a Zidoo Z9X).

Edit:
Sorry my bad, I should do more research.
Double Edit:
Im a dummy, should have let more knowledgeable people to answer this.
Please try

Code: Select all

mp4muxer -i dv.hevc -o dv.mp4
mp4box -add dv.mp4 -add audio.eac3:lang=eng -add sub.srt:lang=ger:txtflags=0xC0000000 -new test.mp4
or see the discussion below. Many thanks @RESET_9999

mp4box mux to Profile 5 dvh1 by default if you don't specify the "dv.hevc:dv-profile=8.1".
But it's not a big problem since most devices still recognize the file and play properly.
Im too lazy to type all those commands, as long as the file plays.

Please make sure you are using the latest mp4box, and your dv.hevc is DV track.
latest mp4box doesnt work with LG TVs

What? But the media info he provides is also not DV, so I don't know which part went wrong.

DV in mp4 can be recognized by most devices, DV in other formats may have compatibility issues.

For LG TVs (at least this is the case with my C8), we have to use the old mp4muxer/mp4box combo(the ones in my tool pack) otherwise DV is not triggered.
