makemkvcon stdout to json

Post by flojo »

This might help someone. There was a few keynames I couldn't determine because I don't know what the values are but, I do believe I was able to correctly name most of the main ones (check the DVD example).

Below are the makemkvcon options used (not sure if --profile matters):
-r --minlength=0 --profile=:.mmcp.xml info

Usage:

Code: Select all

mmc2json.py -p
mmc2json.py -p "file.json"
Help:

Code: Select all

Version 1, 2023-11-12
JSON from the stdout of 'makemkvcon' using the below:
  makemkvcon -r --minlength=0 --profile=:.mmcp.xml info disc:0
 -b, --binary  : set a binary, default is path: "makemkvcon"
 -d, --device  : set a device, default is: "disc:0"
 -j, --JSON    : print JSON in 1 line to stdout
 -p, --pretty  : print JSON line by line to stdout with 2 space indent
                 * can be followed by a filename to write to, ie. -p "mkv.json"
 -l, --line    : print JSON line by line to stdout without 2 space indent
 -g, --guess   : guess the main title number, but guesses poorly.
                 * does not support playlist obfustication
                 it guesses by greatest $byte_size + $most_chapters
                 if no chapters, guess by $byte_size + $length_in_seconds
                 if that fails, guess solely by the greatest $byte_size
 -v, --version : print script version
 -h, --help    : print this help
The script:

Code: Select all

#!/usr/bin/env python3

import json
import subprocess
import sys

binary = "makemkvcon"
device = "disc:0"

# does "--profile" work with makemkvcon?
options = ["-r", "--minlength=0", "--profile=:.mmcp.xml", "info"]

# OK is not used but it is set to true on msg 5011 in msg_parse()
# MSG:5011,0,0,"Operation successfully completed","Operation successfully completed"
