Dolby Vision now possible through MP4 Mux.

[MartyMcNuts]

I was thinking about the stuttering issues people were having with Gemini Man and whether the combination of high frame rate and high bitrate is the cause, so here are some 30 sec sample files (video only, no audio) to see if the stutter issues changes at all. I have re-encoded the base layer to lower the overall bitrate but none of my equipment supports Dolby Vision, so I am unable to test them myself. Anyway, here are the test files.

Feel free to give them a go and report back.

.ts files:
DV_07.09 - https://www.mediafire.com/file/2b8zlvk5 ... s.zip/file
BL+EL+RPU DV_06.09 - https://www.mediafire.com/file/my4qmuh8 ... s.zip/file

.m2ts files:
DV_07.09 - https://www.mediafire.com/file/v2e6nkzc ... s.zip/file
BL+EL+RPU DV_06.09 - https://www.mediafire.com/file/sff991s5 ... s.zip/file

Didn’t think you could re-encode the base layer as it either loses the DV descriptors or doesn’t Mux back in correctly, is this not the case?

I don't know for sure as I my TV doesn't support DV. The re-encoded BL worked ok in yusesope's tool, so I assume it has everything it needed. That's why it I uploaded the files for testing.

Hi everyone

I recently tried to rip few UHD BD with DVDFAB to mp4 dual layer DV with lossy audio and they playback fine on my LG E9 Plex app.
I'm willing to buy a Sony AG9 and i'm askimg if anybody with a Sony Android TV tried to playback these kind of file with Sony Tv Plex App or i need to re-rip movies in Single Layer DV Mp4 using DvdFab?

Wait for feedbacks

Thanks

Try asking over at the dvdfab forum.

Thank you MartyMcNuts

Yes i'll search on DVDFAB forum also but the question is if someone with an Android TV Sony has succeed to playback a dual layer DV mp4 muxed ( with DVDFAB or with mp4muxer also) with Plex app on such TV.

Thanks

Just in case - MakeMKV 1.15.1 preserves DV in MKV - please see https://www.makemkv.com/forum/viewtopic ... 12&t=21937

I was also curious why some were using MakeMKV to use it later with TS muxes for Atmos tracks. AFAIK, MKV should be able to preserve the ATMOS/DTS-X with lossless audio and DV at this point, correct?

It can but nothing will currently play the MKV's. So we're remuxing them with TSMuxer to TS so that we can play them on other devices like the SHIELD Pro 2019 in Plex. At least, that's what I'm doing.

Yep, this is the current solution. However, now that 1.15.1 is out we're waiting for the other shoe to drop where certain software players (Plex etc) update their code to natively handle these files. Once that happens it will greatly simplify our DV UHD backup process.

Hello my friends.

Excuse my poor English, I'm French

I have read all 144 pages and still have same problem : my TV play well .mp4 DV but not my .ts of the same source.

Source is Alita DV teaser demo.mp4 and my TV don't play it.
So, I've demuxed BL.hevc and EL.hevc then remuxed in .mp4 forced DV Profile 4 with mp4muxer and this one play fine on my tv. (EL : Dolby Vision, Version 1.0, dvhe.04.06, EL+RPU, SDR compatible / SMPTE ST 2086, HDR10 compatible)

I also tried with yusescope V3 rev1 tool then remuxed in .mp4 forced DV Profile 4 with mp4muxer and this one play fine too. (Dolby Vision, Version 1.0, dvhe.04.06, BL+EL+RPU, SDR compatible / SMPTE ST 2086, HDR10 compatible)
Works fine with forced DV Profile 5 too, but not in yusescope V3 rev1 tool -mode 2 : Black screen

But file .ts made with tsmuxer with the same BL and EL don't work on my TV. (Video format not supported)
I don't understand. I've tried lot of tsmuxer version (edited,04.06 fix, patched, nightly...)
I don't understand because I've a lot of LG DV demo .ts (dvhe.04.06 BL+EL+RPU) that work on my TV.
For .mp4 files only DV Profile 4 and 5 can work, not 7 or 8. Can't try Profile 6 don't have found the good mp4muxer for.
And for .ts files made with tsmuxer, none of them work, and I can't have dvhe 04.06 with dual layer, only 07.05.

If anyone know what's the problem and help please ?
Thank you a lot guys

Thank you MartyMcNuts

Yes i'll search on DVDFAB forum also but the question is if someone with an Android TV Sony has succeed to playback a dual layer DV mp4 muxed ( with DVDFAB or with mp4muxer also) with Plex app on such TV.

Thanks

You will need single layer ye

[DaMacFunkin]

Just in case - MakeMKV 1.15.1 preserves DV in MKV - please see https://www.makemkv.com/forum/viewtopic ... 12&t=21937

I was also curious why some were using MakeMKV to use it later with TS muxes for Atmos tracks. AFAIK, MKV should be able to preserve the ATMOS/DTS-X with lossless audio and DV at this point, correct?

It can but nothing will currently play the MKV's. So we're remuxing them with TSMuxer to TS so that we can play them on other devices like the SHIELD Pro 2019 in Plex. At least, that's what I'm doing.

In MKV is it possible to retain ac3 core in Atmos for greater compatabillity?

[SamuriHL]

In MKV is it possible to retain ac3 core in Atmos for greater compatabillity?

Mike said that's already being done. It's creating an interleaved thd/ac3 track in the MKV. It's just that at the moment tsmuxer doesn't recognize it when we try to remux, but, in the MKV, it's there.

Does anyone watch dolby vision remuxes on oled and notice some kind of distortion line running continously across the screen during dark scenes? It’s almost like this: https://youtu.be/eJmicmxGdkM (go to 0:29 mark) but way darker and noticeable in a pitch dark room. Yesterday I watched 1917 and this was very evident during dark scenes. I remember seeing the same issue in some other films as well. Is it caused by the remux, the oled or the film itself?

No, I was wrong, or rather I didn't mean it that way. If you extract both TrueHD plus eac3 core, you get two separate tracks in MKV. If TrueHD only - then you get TrueHD only (with Atmos metadata if it was there).
If you want to retain eac3 core, then you have to select it.

What I'm saying, that there is no need for tsmuxer to require eac3 core to begin with. In the worst case, if a 100% compatibility is required, one could always "create" eac3 core from TrueHD, with ffmpeg or any other tool. That core will not have Atmos metadata, but it is discarded by decoder anyway.

There is fundamental differecnce between DTS-HD and TrueHD.
In DTS, the HD layer is extension, you need to have core+hd extension to decode audio.
TrueHD is self-contained codec, eac3 is present on blu-ray only as a fallback. You can mux in a silent eac3 track or leave it empty -- providing you have setup for TrueHD, the player would discard eac3 stream and use TrueHD part only.

So, to preserve the full compatibility one just have to check both streams - truehd and eac3. As for re-encoding to m2ts, MakeMKV uses a tag called a "source id" (now picked up by mediainfo and other software). If two tracks in MKV file have the same source id, then it means that these tracks come from the same source track and have the same content in different encoding. There is nothing that prevents tsmuxer (or any other tool) to recognize two separate tracks this way and join them together. This is what I meant by tsmuxer limitation.
