Off topic -- mpd player and SACD ISO

[Prem Subramaniam]

Dear Maxim,

I know you have been leading the way to get SACD ISO support on mpd player. I have your source code from some earlier work, but there are errors compiling this from source. I don't know if you are still working on it or there is a latest version and I got the wrong one.

So I was able to transfer the SACD and DVD-A ISO modules from your source into Max Kellermean's mpd source and it compiled and is running fine for all other formats -- except of course it does not see the SACD ISO images.  Maybe it needs to read it as a 'data' file? Any comments you can provide would be very much appreciated.

I am willing to do the compiling, and testing is that will help you get this working.

Regards!

Have you add decoders to mpd.conf file?

[Prem Subramaniam]

Thanks, Maxim for replying. I am happy to report I got SACD ISO working ! It plays quite well for the trials I did. Thank you for your source code.

For DVD-A mpd complained about my dvd-a iso..

Yes, I have the decoders in mpd.conf like this: If there is anything else to add please let me know if this can be improved.

decoder {
plugin "sacdiso"
dstdec_threads "4"
edited_master "true"
lsbitfirst "false"
playable_area "stereo"
}

For DVD-A I have this, but mpd got stuck on trying to read dvd-iso file I have only one file, maybe I can test others.

decoder {
plugin "dvdaiso"
no_downmixes "false"
no_short_tracks "false"
playable_area "multichannel"
tags_path "/var/lib/mpd/dvda_metabase"
tags_with_iso "true"
}

Does the plugin show DVD-A track list?

decoder {
plugin "dvdaiso"
no_downmixes "false"
no_short_tracks "false"
playable_area "stereo"
}

EDIT2: SO I was correct. It has to be pure DVD-A, not BR DVD-A which is stuff like DTS_MA etc. The DVD-A iso format also opens now !!!!!!!!!
Excellent!!!!

EDIT I think my ISO is not pure DVD-A. I have to check this? It maybe bluray DVD-A....that will not work , right?

No it fails. mpd crashes. SACD ISO still works.

decoder {
plugin "dvdaiso"
no_downmixes "false"
no_short_tracks "false"
playable_area "stereo"
}

update: reading DVD-A Best of BDA disc 1/best of disc 1 bda.iso

"best of disc 1 bda.iso" looks like Blu-ray disc name. Does this ISO contain AUDIO_TS subfolder with files?

[Prem Subramaniam]

Yes, I mentioned in my two edits that that was the problem. I now downloaded a true DVD-A sampler iso and it now works with that also!!! So yes, the DVD-A must be the DVD equivalent of DVD-A.

I am sure BR DVD-A will be nice to have, but maybe mpd is not capable. I wonder if any module exists in your experience.

[Maxim V.Anisiutkin]

I added some protection against unknown ISOs. The problem with BR is in audio formats (like DTS MA, Dolby Atmos, etc.). Are there any open source codecs for them?

Hello Maxim,

Previously the MPD SACD/DVD-A ISO sources could be obtained both as ZIP archives and via git clone.
Currently I can only find ZIP snapshots on SourceForge.
Is this intentional (ZIP-only releases), or is the git repository temporarily unavailable?

Thanks.

[Maxim V.Anisiutkin]

I moved it to https://github.com/manisiutkin/MPD

[Milan Jovic]

Thanks. It was strange that I couldn't find it with search under Manisiutkin...
Anyway, compiled without warnings or errors on RPi5. Best regards, Milan
