Building

Dependencies

• Python (v3.7 or newer)
• Poetry (latest recommended)

Steps

1. git clone https://github.com/rlaphoenix/pyd2v
2. cd pyd2v
3. poetry config virtualenvs.in-project true (optional, but recommended)
4. poetry install
5. d2v --help

For further information on using the Poetry virtual environment, see Using your virtual environment.

Usage

This project can be used in Python Scripts by importing pyd2v, or in your terminal by calling d2v.

Scripting

from pyd2v import D2V

# ...

d2v = D2V(filename="C:/Users/phoenix/Videos/1998_home_video.d2v")
print(d2v)  # d2v object basic information, e.g. version and settings
print(d2v.videos)  # input video files
print(d2v.settings["Frame_Rate"])  # frame rate
print(d2v.data[0])  # print first frame data

Executable

For help information run d2v --help. Here's some examples of using the d2v executable:

Getting a Setting like the Video Resolution:

$ d2v "D:\...\The.IT.Crowd.S01E01.Yesterdays.Jam.PAL.DVD.DD.2.0.MPEG-2.REMUX.d2v" settings.Picture_Size
[720, 576]

Parse the entire D2V to a JSON Pickle:

$ d2v "D:\...\The.IT.Crowd.S01E01.Yesterdays.Jam.PAL.DVD.DD.2.0.MPEG-2.REMUX.d2v" --json
{"py/object": "pyd2v.d2v.D2V", "path": {"py/reduce": [{"py/type": "pathlib.WindowsPath"}, {"py/tuple": ["D:\\", "...",
"The.IT.Crowd.S01E01.Yesterdays.Jam.PAL.DVD.DD.2.0.MPEG-2.REMUX.d2v"]}]}, "version": 16, "videos": [
"D:\\...\\The.IT.Crowd.S01E01.Yesterdays.Jam.PAL.DVD.DD.2.0.MPEG-2.REMUX.mpeg"], "settings": {"Stream_Type": 0,
"MPEG_Type": 2, "iDCT_Algorithm": 5, "YUVRGB_Scale": 1, "Luminance_Filter": {"Gamma": 0, "Offset": 0}, "Clipping":
[0, 0, 0, 0], "Aspect_Ratio": "16:9", "Picture_Size": [720, 576], "Field_Operation": 2, ... ...

Parse only the D2V Headers:

$ d2v "D:\...\The.IT.Crowd.S01E01.Yesterdays.Jam.PAL.DVD.DD.2.0.MPEG-2.REMUX.d2v" --pretty
<D2V path=WindowsPath('D:/.../The.IT.Crowd.S01E01.Yesterdays.Jam.PAL.DVD.DD.2.0.MPEG-2.REMUX.d2v') version=16,

D2V Properties

D2V objects contain the following properties:

• version: D2V version, 16 is currently the latest for the original DGIndex which was last updated in 2010.
• videos: List of the video file paths that were indexed by DGIndex. It will be just a filename if "Use Full Paths" was disabled in DGIndex.
• settings: Will return various user-provided and auto-evaluated settings based on input data. More information on Settings below.
• data: Indexing data of the MPEG video stream, Each entry is of an I frame which will describe the following non-I frames up to the next I frame.
• data_type: What type of video is most previlent, e.g. 88.4% FILM, PAL, 99.9% NTSC.
