Are there specific ffmpeg mkv capabilities that you use or prefer? Any capabilities that exist in ffmpeg but not in mkvmerge? Thanks.
I think the discussion was meant about muxing libraries which mkvtoolnix probably don't expose, the ffmpeg library for muxing/demuxing is called libavformat I believe.

At what point does it become easier to add eac3to features to ffmpeg than vice versa?

Who said that?

If you're referring to me, I said that it would be easier to add mkv muxing with ffmpeg (libavformat), as eac3to already uses ffmpeg for decoding.

Adding eac3to features to other tools will not be very easy as long as eac3to stays closed-source. That's no complaint, just my thoughts...

@madshi,
I noticed that the haali splitter URL is outdated in the -test info and is now located at the link below if you want to update it.

The whole Haali Media Splitter software as such is outdated. There are fortunately not many usage cases left where parts of it can still be useful...

When demuxing a UHD disc I got an audio file with DELAY -5ms in the filename.

- Does this mean there was a delay placed on the file so it would line up correctly when remuxed?
- Does this mean I need to place a delay on the file when remuxing?
- Is there a way to stop eac3to.exe from changing the output filename when a delay is encountered?

A different disc has an issue with the video.

First pass:
1) 00000.mpls, 00001.m2ts, 2:13:12
- Chapters, 16 chapters
- h265/HEVC, 2160p24 /1.001 (16:9)
- DTS Master Audio, English, multi-channel, 48kHz
- AC3, Spanish, multi-channel, 48kHz
- AC3, French, multi-channel, 48kHz
- AC3, English, stereo, 48kHz
- DTS, English, stereo, 48kHz

Second pass:
M2TS, 1 video track, 5 audio tracks, 5 subtitle tracks, 2:13:12, 11.987p
1: Chapters, 16 chapters
2: h265/HEVC, unknown parameters
3: DTS Master Audio, English, 7.1 channels, 24 bits, 48kHz
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
4: AC3, Spanish, 5.1 channels, 640kbps, 48kHz
5: AC3, French, 5.1 channels, 640kbps, 48kHz
6: AC3 Surround, English, 2.0 channels, 224kbps, 48kHz
7: DTS, English, 2.0 channels, 768kbps, 48kHz
8: Subtitle (PGS), English
9: Subtitle (PGS), French
10: Subtitle (PGS), English
11: Subtitle (PGS), French
12: Subtitle (PGS), Spanish

For some reason it cannot understand the video track on the second pass and will result in a corrupt file if demuxed. I get same result pointing straight at the M2TS also. Using version 3.34.

- eac3to can't apply delay only in TrueHD tracks, and add the string "DELAY -5ms" (I don't know how change this) to remember you add the delay when remux.

With other tracks, not TrueHD, eac3to cut audio frames or add silent audio frames. then can't be always exact, and show the remaining delay in log without modify the track name.

BTW delays smaller than a video frame duration (~40 ms) can be safely ignored.

- The problem with the video track with parameters detected in mpls but not in m2ts seems:

a) If the m2ts play fine maybe it is not supported by eac3to. Cut a sample and upload it to http://eac3to.bugs.madshi.net

b) Or maybe it is corrupt.

Loading the mpls or the m2ts gives same result for the video file.

I will send a sample. What tool can cut the m2ts correctly?

Probably ffmpeg (in command line), and maybe TsMuxer.

I tend to hard cut m2ts using a binary file cutter -- it preserves the file structure.
You can just cut, for example, 200 megabytes from the beginning, reproduce against it and then upload.

DGSplit is for me the best binary cut tool.
