Hi all.
I’ve only just discovered this forum so apologies for diving with the ol’ boring newbie stuff.
I guess the first question should be does it work on a Mac?
If not, this could be the shortest thread on the forum!
If it does, here’s what I’m up to…
I’m trying to get playable audio files from some audio blu-rays that have been authored as BMDV files.
My workflow so far is to use MakeMKV to turn them into MKV files that will preserve all of the high definition & multi-channel audio. I then convert the MKVs into FLAC using Amvidia’s To FLAC converter. This will often output several files when the BD has, say LPCM & DTS-HD versions of the music. I’m using an app called MediaInfo to identify which of the files is which. (I know, I know, once they’re saved as FLACs, the audio formats are identical, I just like to know these things.)
I end up with a tidy set of files but they are, currently, one long file for each Title. I know that MakeMKV can see the chapters because it tells me in the window, I just can’t figure out a way of splitting the long Titles into Chapters so that I can name all the tracks, etc.
Does anyone know a way I can do this? Can I do it with MKVToolNix? I have no cue sheets to speak of.
Thanks. Wading through these replies, I can see that asking ChatGPT was the better move.
What I am confused about is that in the chapters output box, the only thing I can find that works is to put “all” (which I read somewhere else on here). There are 23 chapters & I’ve tried “1-23”, “01-23”, the full range of numbers, comma delineated in various formats (from 1-23 to 001-023). All of these kick up errors. So what is Nix actually asking for here? If “all” is the only thing that works, why is there a box for writing something different?
The “split after chapters” feature accepts either a comma-separated list of chapter numbers (e.g. 1,2,5) or the special keyword all. Ranges (1-5) are not supported. See also the documentation of mkvmerge, the CLI tool that the GUI uses under the hood for the work (entry 7. in that list, but note that you don’t have to enter the chapters: prefix mentioned in the CLI docs — that one’s added by the GUI already, meaning if you select “split by chapters” & enter e.g. 1,2,5 in the GUI the GUI turns that into the CLI argument --split chapters:1,2,5).
BTW, these types of passive-aggressive accusations that translate to “why didn’t you help me sooner!?” is not really helping your case of wanting to receive help. We’re all volunteers here. Please refrain from this level of communication. Thanks.
I know, I’m sorry. I was just being a cheeky bugger.
Going back to your earlier reply, I did try putting in comma delineated chapters in 3 formats…
1, 2, 3 etc.
01, 02, 03 etc.
001, 002, 003 etc.
I just got errors for all of them. But, you know, “all” worked so it’s worked out okay in the end.
If you entered them exactly as you’ve entered them here in your post, it’ll complain about the spaces after the commands. All lists expect entries to be concatenated solely by a single comma, no other characters.
That would explain it, thank you.
Ignore this post. ID10T error, I think.
Been there myself quite a few times, don’t worry 
Post somewhere about something not working, only to figure it out myself a minute later. Classic.
We have all been there! 
On this occasion, once I’d figured it out, it turns out someone on wiki had split one chapter into two and, as they were numbered, it threw all my numbering & naming out by one chapter. I noticed a discrepancy & assumed it was Nix. Took me bloody ages to figure it out!
