nitpick (?): you are confusing readers, by calling a rational number "irrational". I think what you're trying to say is, 24000/1001 can't be expressed as a finite decimal (in base 10).

[Mosu]

Yes, that was what I was going for before confusing things in my head.

Hi Mosu,

When first importing subtitles, and after that importing video into mkvtoolnix, the default output is muxed as a *.mks file. Is this supposed to be?
Muxing as .mkv requires manual setting of the extension.

[Liisachan]

Thanks Mosu. Not sure if this is by design, but several language codes are not recognized as valid: e.g. hbo (Ancient Hebrew), tmr (Jewish Babylonian Aramaic).

@von Suppé
On Windows, at least for me...
1) if I select ASS first and manually select the Destination file without specifying an extension, then .mks is auto-selected and it will be stuck as you pointed out.
2) If I select ASS first and manually select the Destination file with extension .mkv, then .mkv wil be used after that.
However--
3) If I select ASS first and just select a video (MP4/264/MKV/AVI) without selecting the Destination file at all, then .mkv is auto-selected.

So it seems that the most intuitive way would be: First select every source file, then select the Destination file; and the extension will be fine.

Thanks, I understand.

After 18 years of owning the Terminator 2 Extreme DVD, I've finally been able to extract and decrypt the second (DVD-ROM) discs 1440x816 WMV3 video stream (and 6 channel wma pro audio stream).

Currently both streams a muxed within the .wmv container, but when I tried to re-mux the .wmv file into the .mkv container, MKVToolNix reported ".... is an unsupported container format (Windows Media (ASF/WMV))".

I suspect some trickery is required to mux such video streams into the .mkv container but is it possible or am I wasting my time (and everybody else's)?

I've already re-encoded the 6 channel wma pro audio to 6 channel Dolby Digital...


Cheers

As soon as you manually modify/specify a destination file name, the GUI will no longer mess with it. All automatisms such as adjusting the extension or trying to make it unique are suspended at that point. Definitely intentional.

At the moment: intentional; I only keep types "Constructed", "Living" & "Special" from 639-3 right now. The two you've mentioned are "Historical" & "Extinct".

Either that, or start with the source file containing video (as having a video track present & selected will always force .mkv as the extension) before setting the destination file name.

Use ffmpeg.

[Liisachan]

In theory, if the user just inputs the output "file name stem" without an extension, it's still the muxer's job to decide the extension of the output file, before writing it.

However, it's rather unnatural that the user first specifies the subtitle (or audio) source file, then selects the output file name, then selects the video source file. They may happen to do that in some situations, but normally, people decide the output file name after they select all the input files, not in the middle of selecting input files...

So it's based on the 639-3 tables, nothing personal... This too is practically not a big problem at all, but things seem quite random, and potentially touchy, upsetting Semitic peoples; e.g.
- Samaritan Hebrew is still used religiously, but "smp" is refused.
- "Used only religiously" is not good enough? That's why Biblical Hebrew (hbo) is also refused? But Classical Syriac (syc), the Christian language of Peshitta, is accepted. On the other hand Jewish counterparts (tmr & jpa) are refused.
- Imperial Aramaic is a long-dead language, but "arc" is accepted too, not to mention lat & arc.

While you're not responsible for these tables, they may be a bit biased. For the record, 639-3 is maintained by SIL, a Christian organization, which may not be ideal to handle the International standards neutrally. (Not like there's anything we could do about that, though.)

-> so this is probably a bug / missing feature in mkvmerge.

Just noticed the same. This seem to happen only with DTS-ES streams, which is very rarely used on BDs so it's understandable why no one cares. Only two discs out of thousands I have I found that have DTS-ES, the Master Audio variant.

Idk why a centre back channel is so important to actually go and invent all that crap, just settle on 5.1 or go the extra mile to 7.1. Anyway, given that the extra channel is "matrixed" in the two rear channels I understand the actual audio, the "real" channels, are just 6, the 5.1 that mkvmerge labels. mkvmerge should label the audio as 7 channels like ffmpeg does. Or maybe not, given the 7th channel does not matter in terms of the container, as it's not a "real" channel. The 7th channel is "made up" by an ES-aware decoder.

Btw, makemkv produces the same result as mkvmerge.

With DTS-X something similar happens.

Channels is labelled as 8. I understand DTS-X has an MA 7.1 stream as base, so that's where channels come from. Even when the actual X stream is object based (so the "original" labels).


Btw, I can't search for anything in GitLab and all the issues are blank. Weird. We'll have to look into it.

Hey y’all,

not a lot’s been happening over the last couple of weeks wrt. to coding for me, but I thought I’d publish the bug fixes I’ve amassed since the last release. So here you go, a fresh v62.

For package maintainers there was a small change. See the NEWS below.

Here are the usual links: the MKVToolNix home page, the Windows installer/portable version & macOS DMG & Linux AppImage and the source code.

The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are still being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

Version 62.0.0 "Apollo" 2021-10-10
New features and enhancements

• all: IETF BCP 47/TFC 5646 language tags: all ISO 639 languages are now available, even the ones that aren't of types "Constructed", "Living" or "Special".
• mkvmerge, mkvpropedit: chapters: both programs will now write elements set to their default value, too (e.g. the legacy language element if it's set to "eng"). This is done to be more consistent with how MKVToolNix GUI writes chapters. Implements #3210.
• MKVToolNix GUI: multiplexer: when adding new files as attachments the GUI checks if there are other attachments with the same name. If so, the GUI would ask whether to skip the affected files or add them anyway. There's now an option in the preferences to always skip such files, and it's enabled by default. Implements #3213.
• MKVToolNix GUI: chapter editor: removed the support for explicitly setting the legacy country elements. Instead the legacy country elements are derived from the region parts of the IETF BCP 47 languages. Part of the implementation of #3193.

Bug fixes

• mkvmerge: fixed a crash when splitting by chapters is enabled but there are no chapters at all. Part of the fix of #3198.
• mkvmerge: the error message when trying to split by a chapter number that doesn't exist contained the wrong number of chapters that actually do exist. Part of the fix of #3198.
• mkvmerge: AVC ES parser: fixed mkvmerge aborting due to uncaught exception when encountering bad SPS data. Part of the fix of #3176.
• mkvmerge: AVC/H.264 parser: re-added the hack "--engage all_i_slices_are_key_frames" which was accidentally removed in release v61.
• mkvmerge: AVI reader: fixed a crash trying to allocate too big of a memory chunk due to an integer overflows in check conditions. Part of the fix of #3176.
• mkvmerge: HEVC ES parser: fixed another issue with frame type recognition. Certain frames were marked as B frames/discardable on the container level even though they could be reference pictures. Now only SLNR pictures (sub-layer non-reference) are marked that way. Fixes #3192.
• mkvmerge: HEVC ES reader: improved file content detection for HEVC ES files with wrong file name extensions (e.g. ".mkv"), which fixes them being mis-detected as something else, e.g. DTS. Fixes #3201.
• mkvmerge: HEVC ES parser: "end of sequence" NALUs are kept now, and no superfluous flushing will be done when one is found. This prevents splitting NALUs into two different Matroska blocks when they should really be part of a single one, also causing problems with erroneous timestamps. Mostly affects DoVi NALUs. Fixes #3202.
• mkvmerge: Matroska reader, TrueHD: mkvmerge will now probe much more TrueHD frames trying to find the first sync frame. This fixes track detection in situations when a TrueHD doesn't start with a sync frame, e.g. when the source file's the result of splitting between sync frames.
• mkvmerge, MKVToolNix GUI's chapter editor: IETF BCP 47/RFC 5646 language tags: when reading chapters from MPLS playlist files, the "ChapLanguageIETF" element will now be set to the configured default chapter language, not just the legacy "ChapterLanguage" element. Part of the fix of #3193.
• mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: IETF BCP 47 elements will now always be created before writing chapters unless IETF BCP 47 elements are disabled. Part of the fix of #3193.
• mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: when a chapter display element contains legacy language & country elements but no IETF BCP 47 elements and IETF BCP 47 elements aren't disabled, the IETF BCP 47 elements created will contain the region from the legacy element. Part of the fix of #3193.
• mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: Legacy country elements are now created when IETF BCP 47 elements are present & contain a region code allowed in legacy country elements. Part of the fix of #3193.

Build system changes

• The "tools" sub-directory is now always built. The corresponding "configure" option "--with-tools" has been removed. The "install" target still doesn't install them, though.

Have fun 😁

Hi.

Am I missing something, or how do I add Greek (ell) language.

In version 62 it seems to be totally gone. In version 60 there was Greek (grc, Ancient Greek) or something like that.

Maybe I am just missing something.

Never mind.

I was clearly missing something. I was just typing "Greek" in the language area, and expected it to find something. It didn't.

Now I tried to ebter "gre" in the free form input field, and it shows "Modern Greek". Sorry for the inconvenience.

Hello everyone, excuse me a question, if I have to merge two files and I have subtitles in the second track is there any way to do it? because being alone in the second file it cannot merge them with anything since in the first file the subtitles are not there ..... there is a way to merge the two files and put the subtitles only in the second track so that when I review the whole file the subtitles start with the right time, ie in the second track?
Thanks

[Mosu]

Depends on the subtitle format in question. For SRT-style subtitles (CodecID S_TEXT/UTF-8) and SSA/ASS (CodecID S_TEXT/SSA or …/ASS) it is possible by creating a temporary Matroska file consisting of the first file (the one without a subtitle track) and an empty text subtitle file. For SRT this is trivia; just create a text file, leave it empty and save it under "empty.srt". For SSA/ASS it gets a bit more complicated as SSA/ASS contains formatting blocks etc; the procedure is extracting the subtitles from the file you want to append, edit that extracted SSA/ASS file with a text editor & remove all lines starting with "Dialogue:". That way you'll have an SSA/ASS file with the same global header but without content.

MKVToolNix can then recognize empty SRT/SSA/ASS subtitle files & will create a subtitle track in the output file.

Step 2 is taking that temporary file & appending the file you wanted to append originally.

Yeah, and that works for all subtitle formats.
chapterEditor uses empty Blu-ray sups and VOB-subs(idx/sub) to help MTX to get a correct work flow.

I have a collection of old mkv videos that I would like to remux to latest matroska version.

I usually launch (on Windows)

for %%a in (*.mkv) do "D:\eseguibili\media\MKV Toolnix\mkvmerge.exe" -o "%%~na.mkv" "%%a"

but it doesn't keep the original date and time.

Is there a flag or can you suggest me a better batch to preserve date and time too?

[Mosu]

mkvmerge cannot preserve that field. If you need to preserve it, you'll have to retrieve it first with e.g. "mkvmerge -J source.mkv" and set it afterwards mit mkvpropedit.
