mmkv_abi: A Python library for MakeMKV

Post by me_dex »

https://github.com/me-dex/mmkv_abi

Hewwo! I've created a Python library for interacting with MakeMKV. This library allows lower level access into MakeMKV's API's via makemkvcon's ABI which is usually utilized for the GUI. This means that more information can be gathered from both the disc and drive than by makemkvcon's CLI alone; basically any information that's available via the GUI is available via this library. This library also enables finer grain controls over the ripping process. These two features combined means that much more complex ripping logic can be written for automating large collection rips.

In the repo, I included an example script (example.py) which utilizes upper/lower bound duration cutoffs to detect which titles on a disc are episodes of a TV show as opposed to behind the scenes content/the whole playlist. An example run is below:

Code: Select all

$ python3 example.py
MakeMKV version: v1.17.5
MakeMKV platform: linux(x64-release)
MakeMKV build: 999
Interface language: eng:English
Waiting for disc...
Waiting for titles...

In regards to Blu-Ray:

The info really needs to come from within the JRE. Without makemkvcon's source, you should still be able to use the daemon filter to hack your way through it. I hope you do because the data within JRE is, I assume, much more trustworthy.

2 questions:
1. Which information is available via the GUI which isn't makemkvcon?
2. Can you control makemkvcon's SCSI with this? Being able to resume/retry a rip would be handy.

If/when I rip something again, I'll try your script. FWIW, I parsed the output of makemkvcon into JSON via this: viewtopic.php?f=10&t=32370 I didn't spend as long as you on it but, I feel it was pointless unless the data comes from within the JRE. The obfusticated playlist titles really throw a wrench in non-JRE methods. Of course, I'm _assuming_ there is definitive data in the JRE which aids in defeating the obfustication, but I really don't know :-/.

The goal of this project is basically just to provide advanced scripting access to MakeMKV; allowing a more programmatic way to perform ripping of large collections based on heuristics of the collection (title duration, length, language selection, etc) and to allow building of alternative interfaces. It started as a project to provide access to MakeMKV via a web API. It's not really meant to do more detailed information extraction beyond the information that MakeMKV provides.
1. Which information is available via the GUI which isn't makemkvcon?
One example would be drive information. MakeMKV makes available, prior to title scanning, detailed information about the drives that it detected, LibreDrive information, and basic information about the disc inserted (name, protection, etc). This library parses that information pretty much the same way the GUI would.
2. Can you control makemkvcon's SCSI with this? Being able to resume/retry a rip would be handy.
Yes - the library is able to control makemkvcon's SCSI functionality like ejecting a disc. The helper function to do this (eg makemkv.eject_disc(0)) isn't written yet, but it should be added in a later release. It should also be able to detect when a rip has failed and allow for scripting of automatic retries.

Really nice. That should be part of MakeMKV, so that one can be sure it's up2date. :-)

btw: I think you needlessly import pprint but never use it afterwards.


Cheers,
