Dolby Vision now possible through MP4 Mux.

[jayper]

I merged mine in a single TS file.
So if FF works for each individual part, that pretty much confirms the issue is related to the length of the movie.
thank you

Yes but that isn't enough for me

I still haven't got myself a x700 yet, but I dug out my old x800. It can't do dolby vision, but I had some time today and figured it should be close enough to see whats going on (they should be very similar internal players if not the same).

Started with the second hobbit film. The raw m2ts and the tsmuxer file both wouldn't seek. 'Operation not permitted'.

Tried cutting the file with tsmuxer to 2 hours and 45 minutes. Seek worked.

Then I went for 2 hours 50 minutes. Seek didn't work.

Something in tsmuxer caught my eye: "--cut-end=10200000ms"

To me that seemed like such a specific round number. I have now tested both hobbit 1 and 2...

If the file is 2 hours, 46 minutes and 39 seconds or shorter. The file will allow seeking.
If the file is 2 hours, 46 minutes and 40 seconds or longer. The file will not allow seeking.

Turns out in milliseconds that is:

9999000ms: Seeks
10000000ms: Does not seek

From all this, I believe that if the file is greater than (or equal to) 10 million millisconds then seeking will not work. Anything below seems to work fine.

Does this align with what you have experienced on the x700? Know any titles that might be under this 10 million ms 'limit' that don't allow seeking?

Note: For me, on the latest tsmuxer nightly, the resulting file was always 1 second less than what I put into the 'end'. So if anyone tries this, take this into account if you are trying to be precise.

Why there might be such a limit I'm not sure - maybe someone else might know that

Never seen something related to length in ms, at least 10 million...doesn't really strike me as a number that would normally cause issues in the computing world

Has anyone ever figured out a workaround for this issue that doesn't involve splitting the file (which I really would prefer not to have to do)? Surely there's some way to change a setting in tsmuxer that allows the file to be seekable...

If you have an x700 or x800m2, and you're trying to play back a Profile 7 file (ie a UHD with DV), use tsmuxer to create a BDMV folder output. Place the BDMV folder in the root of a USB drive.

To my knowledge, there is no workaround for the seeking issue with TS files. I believe that is a device limitation.

I dont think there's anything you can do about it except using BDMV folder

Oh, if that works, then I'm a happy camper. I'm happy to do it this way, I just want to be able to watch a 3-hr movie without stopping it. I just assumed it still would not be seekable even if I put it on the drive that way. Trying it now!

This is not working for me.

The standalone m2ts file plays fine (albeit without the ability to seek). When I export to a BDMV folder, the X700 sees it as an AVCHD video file (as I understand it should), but it won't play. In fact, attempting to play it just locks up the player to the point that I have to unplug it. I've tried running the original m2ts file through tsmuxer to a BDMV folder and putting it back on the USB drive multiple times, same result every time. Any suggestions?

i dont know, it worked the last time I tried a long time ago and I don't have to bother with this anymore with the x800m2.
Maybe something changed in tsmuxer?

If you no longer use the x800m2, what do you use for DV?

I meant that I don't have to deal with the TS DV rip bugs(FF/RW on long movies or green screen) because the x800m2 does not have any of those problems.

but...
I will soon stop using my x800m2 though because if you haven't heard, the old UGOOS AM6plus is now stable with FEL, supports CMV4.0, and does true TV-LED.

Let's assume that Ugoos AM6B Plus is stable with FEL - will it be better in terms of image quality than x800m2?

Does the x800m2 support CMv4.0?

Since it supports true tv-led, for cmv2.9 content it should be the same quality. I will do a direct comparison with the Shield, AppleTV, and X800m2 once I receive my Ugoos (early April, tracking says)
For cmv4.0 content, on the other hand, the ugoos should be better because cmv2.9 hardware/content have crushed black and cmv4.0 has better tone mapping.

The talk about the stable FEL build is happening here FYI:

On a Sony X700 does a DV m2ts or ts file play in dolby vision as it should or does the player just take hdr10 and present it as dolby vision?

When you say the "old UGOOS AM6plus," do you mean this version? https://ugoos.com/ugoos-am6-plus-android-9-4-32-gb

Not the 2021 Version?

[RESET_9999]

I ordered the AM6B+. I think the only difference is the wifi 6

Trackings says it has now arrived in my country, I might get mine sooner than expected

Is this one the only model that can theoretically playback Dolby Vision correctly or the newer models can too?

I don't know but all the tests and development are done with the AM6+

[bobbymkV]

If anyone is interested in a deal on a barely used AM6+ shoot me a message (I'm based in the US). My days of being obsessed with DV playback have long past

On a Sony X700 does a DV m2ts or ts file play in dolby vision as it should or does the player just take hdr10 and present it as dolby vision?

It will present DV correctly, but you must do things exactly right. I have FINALLY figured this out after a ton of trial and error.

For MOST DV movies (anything under 169 minutes or so), follow steps 1-3:

1. Rip the FULL DISC with MakeMKV. Do NOT make an mkv with MakeMKV. Full disc rip only.

2. If you don’t need to swap out any audio or subtitle tracks, you’re ALMOST done, but you MUST take the movie file (the largest m2ts file in the BDMV\Stream folder) and directly export it AGAIN as an m2ts with tsmuxer. I don't know why, but the HDR layer will NOT read as DV unless you do this (you can verify this with MediaInfo). The resulting file will play on the X700 in DV just fine.

3. If you do need to swap out audio or subtitle tracks, then open the movie m2ts file (from step 2) in tsmuxer, make your audio and subtitle selections, and then - and this is important - export to m2ts, NOT to a BD folder. This is the file you can play on the X700.

Now then…this is what I’ve found out - I have no idea why, but exporting to a BD folder with tsmuxer will somehow break the DV layer. It will read as HDR10 in mediainfo, and the X700 will also read it as HDR10. The ONLY WAY to preserve the DV layer is to export to m2ts, NOT a BD folder. You can check this yourself. Check the mediainfo (tree view) of your original m2ts file, and then check it again after exporting both ways. Exporting to m2ts will retain DV, but exporting to a BD folder will not. So with this in mind…

For LONGER DV movies (anything over 169 minutes) that will not natively seek on the X700, add these next steps to the ones above:

1. Once you have your final m2ts file from the steps above, take THAT file and put it BACK in tsmuxer. At this point, export to a BD folder (don’t worry, we will still keep the Dolby Vision, but the BD folder export is a necessary step here). Do not delete the m2ts file you used here. You will need it for step 2.

2. Go into the BD folder you just created, into the BDMV\Stream folder. Now this is important - the m2ts file you just used for the previous step? We will call that file A. Name it exactly the same as the m2ts file in your new BDMV\Stream folder (we will call that file B), and COPY and OVERRIDE file B with file A. What you’ve basically done is have tsmuxer make you a BD folder, but you’re replacing the m2ts file it just made with broken DV with the original one you had with intact DV. The BD folder structure will still work perfectly.

3. Copy the BDMV folder into the root of your USB device, and click on “AVCHD” on the X700 and this will make a 169+ min m2ts file seekable, maintaining DV in the process.
