Demuxing a HD-DVD issues

[Phoenix_82]

Hi there,

I have a HD-DVD and I'd like to remux it as .mkv.

I'm having problems with its subs though... eac3to simply doesn't seem to recognize them. They are present, however, in the "ADV_OBJ" folder in the HD-DVD folder structure (as ACA files). The disc supposedly has German, Danish, Finish, Swedish Norwegian and Dutch subtitles.

Here's the log with its playlists and the main playlist itself:

eac3to v3.34
command line: eac3to "b:\L'ARMEE DES OMBRES"
------------------------------------------------------------------------------
1) L0_mainMovie.EVO+L1_mainMovie.EVO, 2:24:17
"MainMovie"
- VC-1, 1080i (16:9)
- DTS-HD, French, 2.0, 48kHz
- DTS-HD, German, 2.0, 48kHz

2) trailer.EVO, 0:03:52
"Trailer"
- VC-1, 1080i (16:9)
- DTS-HD, English, 2.0, 48kHz

3) advanced.EVO, 0:00:30
"SpecialFeatures"
- VC-1, 1080i (16:9)
-----------------------------------------------------------------------------------
eac3to v3.34
command line: eac3to "b:\L'ARMEE DES OMBRES" 1)
------------------------------------------------------------------------------
EVO, 1 video track, 2 audio tracks, 2:24:17
1: Joined EVO file
2: Chapters, 12 chapters
3: VC-1, 1080p24 /1.001 (16:9) with pulldown flags
4: DTS Master Audio, French, 2.0 channels, 16 bits, 48kHz
(core: DTS, 2.0 channels, 1509kbps, 48kHz)
5: DTS, German, 2.0 channels, 768kbps, 48kHz

I know that eac3to supports HD-DVD. In fact, I can demux that main playlist just fine. Without the subs... I just wonder if there is something regarding subtitles that I'm not aware of.

Many thanks in advance for any feedback on this

That's indeed strange. Demuxed a couple of hd-dvds with older or newest versions of eac3to and never had issues with demuxing subtitles. Maybe this is some oddly mastered disc?

[Phoenix_82]

Thanks for your reply.

I did demux successfully a handful of them in the past. With no issues regarding subtitles. I have no idea if it is a problem with the disc. It seems otherwise fine.

Actually, I asked for help elsewhere and someone managed to extract the subs (somehow) from those .aca files but it's just a collection of PNGs and xmu and xmf files. If I had a .xml indexing those images I might then use BDSup2Sub and export them as SUPs. It's not the case. He says I'd need custom tooling to convert those files to PGS.

I just wanted to try and understand how could I get eac3to to actually 'see' them and do things the way I always did. Both DGDemux and MakeMKV also can't read them and eac3to was always my most reliable tool.

Obscure HD-DVD functionality? No. She's dead, Jim.

Thanks for asking, Phoenix_82! I think it may be about 2-bit versus 8-bit VOBSUB, aka 'extended VOBSUB'. Whatever.

Would it be possible to investigate this exact issue or is it not worth it for one disc or rather dead disc format? I mean when Curly is available ofc.

Curly is back in town tomorrow so I'm sure he'll reply.

We don't have any HD-DVD disks or a way to rip them. Can you give us what we need?

Hey Curly, check PM .

P.S. Subs there in ADV_OBJ folder in .aca files like subda.aca, subfr.aca etc.
There is Danish, Dutch, Finnish, French forced guess, German, Norwegian, Swedish subs.

It's first HD DVD for me that eac3to can't manage with subs to extract them to .sup like for other guys.

Interesting if you could figure out this one rare case .

[Curly]

Thank you, Harry. Downloading...

eac3to is king for hddvd so lets make it better
i got yer streams, you r the man HPotter
one stream working, one not, so clear!
God willing we see the reason and humbly ask the
divine spirit to energize and direct us, so that we may directly
and indirectly pay homage to creation.

[Sherman]

So sayeth the Curl.

[Curly]

OK guys, here is where things fail:

Code: Select all

if FEvo then
  for i1 := 0 to 31 do
    if dword(pointer(@buf[pos + 6 + $223 + dword(i1) * 4])^) <> 0 then
      InitOutput(false, false, i1, 'evo/sub');

For the good disk, InitOutput() is called. For the bad disk, InitOutput() is not called. So the test above the InitOutput() call is failing. In order to go any further I need someone to link me to the HDDVD specification that covers subtitles. Without that I cannot decipher that test. I've looked around a bit online but haven't found the spec yet.

BTW, have y'all tried evodemux for these disks?

evodemux, makemkv etc don't see subs here as eac3to for L'ARMEE DES OMBRES disk.

Fow now found those specs:
Requirements Specification for HD DVD Video Application v. 1.0

http://www.dvdforum.org/images/Requirem ... ly2005.pdf

HD DVD-Video Product Requirement & Guideline:
v 1.0 https://www.dvdfllc.co.jp/pdf/HDDVD-VR_ ... de_V10.pdf
v 1.03 http://www.dvdfllc.co.jp/pdf/HDDVD-Vide ... e_V103.pdf
v. 1.2 https://www.dvdfllc.co.jp/pdf/HDDVD-Vid ... de_V12.pdf

[Curly]

Thanks but there's nothing useful there. I need the syntax/semantics for subtitles on HDDVD.

[Curly]

OK guys, I'm going to put this aside for now. If a spec falls into my hands we can resume it. Please post here if anyone stumbles on the spec. For now I want to get a new release out with the -nolog option and the fix for 2-pass FLAC.

Hi, I also ran into a disc with this issue, and I dug around a bit, I found a few useful resources.

This tool, available as binary and Java source code can unpack the ACA archives:
https://www.softsea.com/review/DumpHD.html

Here is a Spanish paper describing the standard:
https://upcommons.upc.edu/handle/2099.1/4599

After unpacking, you get PNG files and some .xmu files describing the the timing/position. That should be possible to convert to SUP.

edit: I had luck making a BDN XML with the data in the file, and then converting that to SUP. Images and positions are in the same format, just have to convert timestamps.

ta Superb
thing is with all the available workarounds
shud we really bother
wanna go forward not backward

[HPotter]
