MakeMKV: 1.12.2 for Windows.
DVD: King Crimson's "Beat" KCSP9. It's a DVD-A, but the content I'm trying to extract is in VIDEO_TS. The disc, according to both MakeMKV and DVD Decrypter, has no encryption or protection whatsoever: My goal is to extract the DTS stream, wrap it in FLAC and play it on a Logitech Squeezebox, something I've done many times with other discs with no issues.
The problem: When I open the disc in MakeMKV and look at the title I care about, the chapters look perfect: However the MKV that gets created doesn't play in VLC. It opens, just sits there for a while, then suddenly scans to the end without ever actually playing. The timeline in VLC reports a reasonable time, it just doesn't play.
If I open the MKV in AudioMuxer in order to demux the audio content and split into individual song files, the chapters that initially looked good in MakeMKV become:
AudioMuxer winds up creating nine output files, the first eight of which are very small and silent, while the final one contains all the audio. Although VLC will not play the MKV at all, the audio as extracted by AudioMuxer from that same MKV file is good.
Code: Select all
CHAPTER01=00:00:00.000 CHAPTER01NAME=Chapter 01 CHAPTER02=00:00:00.033 CHAPTER02NAME=Chapter 02 CHAPTER03=00:00:00.066 CHAPTER03NAME=Chapter 03 CHAPTER04=00:00:00.100 CHAPTER04NAME=Chapter 04 CHAPTER05=00:00:00.133 CHAPTER05NAME=Chapter 05 CHAPTER06=00:00:00.166 CHAPTER06NAME=Chapter 06 CHAPTER07=00:00:00.200 CHAPTER07NAME=Chapter 07 CHAPTER08=00:00:00.233 CHAPTER08NAME=Chapter 08 CHAPTER09=00:00:00.266 CHAPTER09NAME=Chapter 09
If I bypass MakeMKV and open the disc directly in AudioMuxer (remember, the disc is not encrypted), I get the expected results. The chapters are reasonable:
And the output files are exactly what I'd expect, one file per song, properly split.
Code: Select all
CHAPTER01=00:00:00.000 CHAPTER01NAME= CHAPTER02=00:04:24.264 CHAPTER02NAME= CHAPTER03=00:08:16.496 CHAPTER03NAME= CHAPTER04=00:11:50.710 CHAPTER04NAME= CHAPTER05=00:16:16.976 CHAPTER05NAME= CHAPTER06=00:21:07.266 CHAPTER06NAME= CHAPTER07=00:24:30.469 CHAPTER07NAME= CHAPTER08=00:28:43.722 CHAPTER08NAME= CHAPTER09=00:40:54.953 CHAPTER09NAME=
I can't figure out why MakeMKV sees the proper chapters when it opens the disc, but they don't carry over properly when creating the MKV. Or at the very least, VLC and AudioMuxer do not see them correctly.
I've seen this behavior with other discs, and while the problem discs aren't all DVD-A (that is, many do not have anything in AUDIO_TS), I think they may all be discs where the content is largely musical and the "video" is really just still images or slideshows. It's possible that I only think that's relevant because most of why I try to do involves that type of disc.
