Some Python scripts I use for BluRay re-encodes

One of my hobbies is managing a media server which involves backing up BluRays, and preparing their contents for my server.

These are some Python scripts I wrote to make the process more automatic.

Extract Bluray

The extract_bluray script will batch mkvmerge files from a BluRay.

It will ask the user for filenames with the extension mpls, or m2ts, and will ask for an output folder name which will be automatically created later.

After that the script will begin creating source.mkv files.

The script will also create a bluray_data.json file in the event that the script is killed prematurely. If the script finds the bluray_data.json file on the next run it will ask the user if they want to just use the json file instead of creating a new list of files to extract.

'batchconvert.py' Usage

Each source.mkv will sit in its own folder, and along with it will be a info.json.

The info.json file contains information about the video which will determine the resulting video file.

(utils/info.py can be used to generate an info.json)

vapoursynth-filter.py can be used to pre-process the video via VapourSynth during transcoding. This is useful for deinterlacing, cropping, and/or resizing.

(See example info.json and vapoursynth-filter.py)

Example directory structure:

bloopers/source.mkv
bloopers/info.json
deleted-scenes/source.mkv
deleted-scenes/info.json
deleted-scenes/vapoursynth-filter.py
batchconvert.py

Requirements (I think I got all of them.)

• mkvtoolnix
• ffmpeg
• bdsup2sub (or bdsup2sub++) "The script needs to know where bdsup2sub is at."
• VapourSynth
• psutil (Only used for setting cpu priority)
• sup2srt
