Bluray Audio to FLAC

[ultradj83]

Dears,
I'm trying to rip a Bluray Audio disc to FLAC.
This disc contains a video track just showing titles and a 96kHz 24bits 5.1 channels LPCM audio track.
There's only 1 title splitted in 9 chapters, each one containing a song as usual, and here's the issue.
I want to rip each song to a FLAC file, but chapter markers are only seen by players (ex. VLC, Media Player Classic, etc.), while any rip software (ex. Handbrake, MakeMKV) sees a single chapter.
I'm not in touch with Bluray structures, but I've always been able to rip Bluray disc, all the times but this.
On this disk the structure is in the IISVPL/00000.vps file containing this:

MPLS0100 : ¦ 8 h `00000M2TS ›üÀ øðç > A €deng eng Ž
›üÀÿÿ ý¹úÿÿ D^Yÿÿ ‚Z ÿÿ Ñûÿÿÿ ì jÿÿ |þRÿÿ ì ÿÿ iŠöÿÿ CD4ÿÿ PLEX D Þ ÿÿ ( #& Yes - Fragile (multiAVCHD) –

00:26:48 ÿÿÿÿ ( #&
00:29:50 ÿÿÿÿ ( #&
00:41:20 ÿÿÿÿ $

How can I rip any chapters to the related FLAC file?

Thanks and best regards.

I would probably rip the title with MakeMKV, then use FFmpeg to transcode the audio to FLAC one chapter at a time using the timecodes in your VPS file.

[ultradj83]

Well, MakeMKV can create a .mkv file in the standard way or directly transcoding audio track to FLAC, but in both ways chapters are lost.
Thanks.

Rip the title to MKV using MakeMKV (this will keep chapters intact as metadata) then convert with AudioMuxer.

AudioMuxer can split the audio at chapter points.

I know Handbrake has no LPCM support, but its scan log can be interesting:

Rip the title to MKV using MakeMKV (this will keep chapters intact as metadata) then convert with AudioMuxer.

AudioMuxer can split the audio at chapter points.

With this disc Make MKV doesn't keep chapters.

The only converter that reads these chapters I found is Xmedia Recode.
I'm trying to convert the disc to a .mkv (copying video and converting audio to FLAC, it doesn't allow to keep LPCM in the .mkv), then I'll try to use Foobar to split files.

An other idea is to directly create splitted FLACs with Xmedia Recode, it allows chapters selection.

I'm also giving a look to Audio Muxer, sounds interesting.


Thanks!

It works perfectly creating FLACs directly on Xmedia Recode (I think it's perfect, just need to eventually check gapless, I have no gapless Bluray Audio sources):

Every Blu Ray title I've ripped with MakeMKV has always kept the chapters. You will get one long MKV file, but the chapter points are saved in the metadata of the MKV file. When you import the MKV file into audiomuxer, it can then split the converted audio at chapter points.

Usually, MakeMKV includes in the.mkv file a chapter markers track.
It's enough to open the .mkv with MKVtoolnix or Handbrake to see and check it.
This time it doesn't, this is the point, it's the 1st time I encounter this problem, too.
Maybe Bluray Audio uses a different structure.
It's saved in the directory I said and there's a copy of that file in /BMDV/playlist.
Unfortunately I'm not expert in Bluray structures, I don't know if this is the same of the normal Bluray Video structure, I can only confirm Xmedia Recode is the only ripper/converter detecting the structure with this disc...

Ripping a BD Audio disc (Tears for Fears Songs From The Big Chair)

As you can see their are 8 chapters (songs) in the title

The first three screen shots are from MakeMV where I ripped the 5.1 LPCM audio to a MKV

Last three are from AudioMuxer converting the MKV's audio to FLAC and as you can see the audio is split by chapter points.

[ultradj83]

I just have no chapters line in the MakeMKV tree...

[Arnold_Layne]

Reading your previous posts, it would seem this is a downlaod of an .iso file somoene created with multiavchd. This is why MakeMKV isn't working. You are not ripping an actual Blu Ray structure.

[ultradj83]

Well, I don't know what Multiavchd is and what is used for, I will read about.

Thanks.
