tsMuxer Open Source

[yannick92]

Other strange things too:

The information for track E-AC3 is ok on the old 2.6.12, but not on the latest version?
I tested with several .mkv with an E-AC3 track and there is always the same error.
Why?
thank you

Hey guys,

I'm hoping someone here can help me...I have wasted so much time trying to get this joined properly.

So as some of you may know, some long 3D movies (eg:- The Hobbit, Titanic, etc) are in 2 parts.

Seems pretty straight forward, you just append them using tsmuxer, and in practice, it does, HOWEVER, after running it thru, if you navigate to the "join point", there is a noticeable approx 1 second of "black", then when the 2nd part starts, the audio is out of sync...the same length as the "black" section that somehow appears when joined.

Is there some way that this "black" section doesn't happen ??

@Pauly Dunne just to be sure, you added the mpls file in tsMuxer, rather than add the first m2ts and "append" the second m2ts file ?

Using tsMuxer:
In "Input" -> "add" adding an .mpls or .m2ts (24.000 FPS) video file and adding a .sup (24.000 FPS) subtitle file.
Output to Blu-ray folder.
--------------------------
The output subtitle is out of sync, it starts OK but then gradually goes out of sync.
I can't figure out what I'm doing wrong?
Could it be a bug in tsMuxer?
If I use a mediaplayer like PotPlayer or MPC-HC and load the .sup subtitle sync is perfect.

@varekai not sure to understand... if your player shows the sup subtitle perfectly synced, it means it already has the images timestamps for 24fps -although the file is marked as 23.976. So when you convert from 23.976 to 24 fps with tsMuxer, it becomes out of sync.

Edit : seems to be linked to this easysup bug https://forum.doom9.org/showthread.p...13#post1451113

Hi, I just knew someone would ask that, and tbh I should have said so !!!!

Yes, I've tried both methods, several times, same result

I posted a way to do this a few years ago. Instead of joining playlists join ssif files. The results are seamless. Only thing I had to do was to fix chapter marks on second half. I’ll see if I can locate it and post link here.

Hello!

That is a good find! Thanks!
I suspected it could be a bug in easySUP.
I'm definitely gonna try bdsup2sub!

What I'm doing is I demux .sup files from a Blu-ray with tsMuxer. 
Import .sup to Subtitle Edit, do some editing, and save as .srt 
Opening .srt with easySUP and apply settings like font, size, style, margin, etc. 
(This .sup plays in sync when playing video (.m2ts or .mpls) in PotPlayer or MPC-HC and then adding .sup.)
Then add the Blu-ray in tsMuxer, removing unwanted streams, adding one or two easySUP generated .sup files. 
This is where it goes wrong.
tsMuxer auto reads (wrongly) the .sup as Frame rate: 23.976 so not anything I can control. 
tsMuxer then tries to auto change the FPS .sup to 24 to match the video wich results in a out off sync .sup.

So to sum it up, tsMuxer is not the culprit... sorry...

Best regards,
varekai

IMO, it is possible to fix this problem with MkvMerge.
For the audio sync issue, there is probably a solution with the CLI argument --append-mode:

appending files.

I think that it uses track by default, and that means that it joins each track independently. If the durations of the video and audio tracks of the first part are notably different, the audio will be out of sync. I guess that using file mode may help. (I don't know if it is possible to provide this argument with the GUI. Perhaps in Input -> Properties -> Miscellaneous -> Additional Options, but I have never tried.)

Also, if there is a blank at the end of the first part, you can remove it with the option Multiplexer -> Output -> Splitting -> Split mode: After specific timestamps. With some luck, you can cut the blank just at the end of the audio, or a bit before, and the second part will be in sync (with a very small delay due to the different durations of the video and audio frames, but that delay is so short that it should not be noticeable).

OMG Hart2hart, that info it EXACTLY what I need, I found a post that I could have written, it spot on

So I can't wait to try this process, and hope I have the same success as the OP had.

edit:- unfortunately, this did not work for me, still got the black frames at the join, and hence, sync was out, after that

I certainly came to the right place

I have a couple of other 2 part 3D movies, hopefully they will go thru tsmuxer without issue, but Titanic is a problem.

Cheers

Hi r0lZ,

As far as I know, MKVToolnix/MKVmerge doesn't process MVC (SSIF) 3D movies...it leaves out the SSIF/MVC track.

The ONLY app that I have found that DOES, IS tsmuxer.

I'm pretty sure that there are not any black sections at the end of the 1st part, or the start of the 2nd part. If you watch the movie in question (Titanic), that is NOT a joined non 3D version, and watch it at the 2 part version join point, there are NO "black" frames at all.

However, I appreciate your reply & suggestions, that I will give it a try in the future.

Cheers

@yannick92 the "secondary" checkbox was already there with 2.6.12. The secondary audio is for PiP (Picture-in-Picture) videos.
Edit : secondary audio is possible only with E-AC3 and DTS Express.

Patch has been submitted for fixing the bitrate and channel.

AT LAST!

In file w64-nightly-2020-02-05--01-09-49.zip

the 24-bit DTS Express "bug" in the GUI has been "fixed"
(so to speak)

You can create the AVC+MVC MKV with MakeMKV. But I don't know if you can then use MkvToolnix to join the two parts, or cut the black section.
And, of course, if you want to recreate a 3DBD, tsMuxeR is better.

Sorry to be a pain, but would there be any chance of muxing single layer Dolby Vision?

@mattmarsden could you please be more specific ? tsMuxer already muxes single layer DV hevc streams.

Try eg dolby-vision-amaze.mp4 (DV Profile 5) or P81_GlassBlowing2.mp4 (DV Profile 8.1)

Or you could simple load the srt in tsMuxer, conversion to sup works well on Windows.
Alternatively, open the sup produced by easysup with an hexeditor:
- bytes 14-15 are width (0x0780 = 1920)
- bytes 16-17 are height (0x0438 = 1080)
- first nibble of byte 18 is fps: = (0, 23.976, 24, 25, 29.97, 30, 50, 59.94) => change from "10" to "20"

Both of those sources crash my OPPO when muxed using the 'Blu-ray Folder' output option...

To my knowledge, standalone players don't have to be compatible with single layer DV streams. I can't see what can be changed on tsMuxer.

I have a few single layer Dolby Vision test files that work fine with the OPPO.

Ok, thanks @SeeMoreDigital. I'll try to see what's different from tsMuxer outputs.
