I sincerely apologize for the misunderstanding. When I saw ‘encode log,’ I assumed it referred to the process of x264/video encodings and their stats, rather than the project’s log.

No biggie.

It’s not an issue with the encodes. Whenever the clip (the streams) contains a part at its start that is to be skipped according to its corresponding playlist file, BD-RB doesn't retain the (PlayItem's) IN_Time at its original value and changes it to 00:00:00:00. This could be due to the commands BD-RB sends to tsMuxer (Or the "Rebuilding BD file Structure"). The attached image shows the original structure as imported into Scenarist by a BD-Reauthor script. The black frame that reads ‘Cinerama Everywhere, RT 8:20…’ is a shot of the short part at the start of the clip that is not intended to be played back.

If I rebuild the same title (even with the FORCE_NOENCODE=1 flag?) and then import the rebuilt version into Scenarist for re-authoring, the aforementioned IN_Time is not the same as in the original MPLS. When that playlist/clip is called from the disc menu, those few frames at the start of the clip play back because the IN_Time has changed. Maybe something like BDTools can correct it in MPLS files.

PS
For this particular clip, the “IN_time” of the PlayItem and the “mark_time_stamp” of the first “PlayListMark” in the original playlist MPLS (converted by BDTools to readable JSON) is 27167041. However, in the BD-Rebuilt version, it has changed to 27000000.

    }
}

I believe this issue can only be resolved by a reverse conversion of the JSON file back into an MPLS playlist after BD-RB’s work.

BDEdit can also revert the PlayItem IN_time from the initial setting to the original authored value. However, I am curious as to why this behavior occurs in the first place. Is "Rebuilding BD file Structure" a process similar to what IfoUpdate did during the DVD era? Does it fail to read the original IN_time value, or is the issue caused by the muxing process when the main clip of the PlayItem is changed?

When dolby vision support was first added to BD-RB there was an initial release where the dolby vision track was given the wrong stream ID, this bug was promplty fixed by the author BUT was never fixed in the internal routine that handles the correction of bitstream exception errors returned by tsmuxer, resulting in the m2ts file where bitstream exception occured being unplayable with dolby vision enabled.

If i then demux BD-RB output the dolby vision track on an affected m2ts file where bitstream exception occured demuxes as track_4114 rather than track_4117.

Im hoping this is just a code correction for the author.

Thankyou

Hello j dobbs, did you get chance to look at the above bug, Regards

[DoctorM]

New Win OS and installation of BD Rebuilder first being used today and I received the "TSMUXER ERR: 0xFFFFFFFF" error trying to do a movie only rebuild.

I saw a few instances of it mentioned here but never a solution. Digging around I found that one of the .M2TS files was accidentally missing so the .MPLS couldn't find ALL the video files in the main movie's playlist.
Putting the missing video back and the error went away.

I don't know if that's why anyone else got that error, but I just thought I should mention it in case it helps others.

I have it on my list of things to do. Unfortunately I haven't had a lot of time recently to work on BD Rebuilder, but I hope to address the things on my list soon.

[Lathe]

Just a quickie... (as is my known usual style... )

I THOUGHT I remembered in the past that using TSMuxer the box 'Continually Insert SPS/PPS' was always checked, unless I am misremembering. But, I'm using a newer version of TSMuxer now (still from aways back) and I notice that be default the box is UNchecked.

I'm ALWAYS creating playable Blu-ray compatible discs to play in my OPPO player, so, should I leave the box unchecked now or should I use it? I am rather confused... (what else is new....?)

And, in answering, if someone could kindly please explain exactly what that does and why that is there and why it is (UN)necessary?

Thanks!

***EDIT

Oh, I also notice that the older version I use sometimes (2020) also defaults to 'Insert SEI and VUI data if absent'... Uh, what is that about, and why does the newer one default to 'Do Not Change' that? AND... Again, PLEASE, what are the differences, why do both versions default differently, and how should I set these to make the most compatible playable Blu-ray discs for hardware players?

thanks again!

Anyone home...?
