"automatic sdf downloading is disabled or failed" while decrypting

Post by ikomrad » Sun Aug 19, 2018 3:28 am

After I inserted the John Wick (2014) blu-ray and click on the disk icon to decrypt it, so saw this error in the output / log section -

"automatic sdf downloading is disabled or failed"

However , makemkv continued to process the disc, listed the titles, and even highlighted the probably main title as "FPL_MAINFEATURE".

I checked "Preferences->General" and downloading updates from the web server is enabled. What is the web server hostname? I have pi-hole and pfBlockerNG running to filter DNS requests. I can check their logs to see if they blocked it. I found requests for makemkv.com which were allowed, so we are good for that domain :)

Is it a serious problem that I should look at fixing? I don't know what SDF is so some context would be helpful.

Software info:
MakeMKV: 1.12.3
OS : MacOS 10.13.6
Java: 1.8.101

Is there any way to white-list entire MakeMKV? I short, it can use any DNS address and it can change at any time.

It is still a little secret, but having this file is good for you. You can always download SDF.bin manually from http://www.makemkv.com/svq/sdf.bin and put it into MakeMKV data directory. On next launch MakeMKV will consume the file and shut up.

You can whitelist top level domain, subdomain. So if Makemkv buys a new domain and switches to it, you'll need to update the whitelist on pi-hole. Domains cost money to register and renew, so I wouldn't think MakeMkv would change domains often.

I've tried the sdf.bin file but it doesn't work for me. The file is deleted once MakeMKV starts, but discs that are recognised when MakeMKV is connected to the Internet are not recognised when offline. I can't think what I'm doing wrong as it couldn't be any simpler?

The sdf.bin file is actually "moved" into a file in your MakeMKV data directory, called _private_data.tar, and read from there. This file keeps all of what MakeMKV downloads for operation, so it (usually) isn't overwritten by other programs.

_private_data.tar hasn't been modified since the 31st of July, so it hasn't been updated with the sdf.bin file today. I've moved the file away, copied sdf.bin back and started MakeMKV and _private_data.tar has recreated, but it still doesn't contain the key for a disc I know has been added.

To clarify, the PC is not connected to the Internet, which is why I'm trying to manually import the keys from the sdf.bin file. Perhaps I have misunderstood the point of it?

This topic has gotten so old, are you talking about the John Wick 2 disk failing (what started the topic), or a different disk?

JW2 is a long-ago solved issue, but it is possible the disk you're having an issue with is "too new".

In your MakeMKV data directory, there will be a file created for any "unknown key" disks, that starts with "MKB". What is the name of the file created for this disk?
