@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I noticed that the haali splitter URL is outdated in the -test info and is now located at the link below if you want to update it. https://haali.su/mkv/ |

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?

Hi.
This is a general eac3to question, but also has to do with audioconversion. I am using eac3to 3.34 and am trying to demux a disk with several audiotracks like this: 8: E-AC3, Czech, 7.1 channels, 768kbps, 48kHz, dialnorm: -27dB (core: AC3, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB) When I do "eac3to 1) -demux" it says: a08 Applying (E-)AC3 delay failed. Seems like eac3to can't demux audio streams like that. Maybe because it is 7.1? I would then like to demux all other tracks than the e-ac3 tracks. Is there anyway to tell eac3to to ignore some tracks when using -demux? There is 20 subtitles or so on the disk, so making a manual command line including all tracks but the e-ac3 tracks is quite cumbersome. When I have to name the tracks manually like 15: English.sup I also Loose all the information that eac3to usually uses for the filename. Number of subs in track, and if there is any forced subs in the track. Any help will be much appreciated. Thanks in advance. rco133 |

Yes, is a bug already reported here: http://bugs.madshi.net/view.php?id=450
More info: https://forum.doom9.org/showthread.p...43#post1821743 I don't know how help you.

No, changing speed requires re-encoding and eac3to can only encode to the following formats:
(1) RAW, (L)PCM (2) WAV (PCM only), W64, RF64, AGM (3) WAVs (multiple mono WAV files, PCM only) (4) AC3 (5) DTS (6) AAC (7) FLAC You can output to WAV and encode that to eac3. But be aware there are different eac3 "flavors": https://forum.doom9.org/showthread.php?t=174418 |

Video is a discrete medium, frames appear at specific times and stay for a specific while, therefore you can change quite easily their display duration; but audio is a rather continuous medium, changing the playing time (with or without preserving the pitch doesn't matter much) is always a substantial change of the whole content, usually requires decoding, resampling, and new encoding. There may be a quite simple AC3 encoder in eac3to, but E-AC3 is not supported, AFAIK.

MkvMerge can shrink or stretch the audio streams by a specific factor without re-encoding. I don't know how it does it, and if the quality of the audio is less good after the operation. I suppose that it changes just the sampling rate (and therefore also the pitch), but I'm not sure.

MkvMerge simply stretches/compresses the timecodes. In the end you either have all frames slightly overlapping with each other or tiny gaps between all of them. Players may react badly to this so I don't recommend it. Better to change video fps in case re-encoding is not desired.
