A Python Parser for DGMPGDec's D2V Project Files.

## Installation

    pip install --user pyd2v

## Building

### Dependencies

- [Python](https://python.org/downloads) (v3.7 or newer)
- [Poetry](https://python-poetry.org/docs) (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](https://python-poetry.org/docs/basic-usage/#using-your-virtual-environment).

## Usage

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

### Scripting

```py
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:

```shell
$ 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:

```shell
$ 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:

```shell
$ 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,
data_type='100.00% VIDEO\n', 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, 'Frame_Rate': ['25000', [25, 1]], 'Location': {'StartFile': '0', 'StartOffset': '0',
'EndFile': '0', 'EndOffset': '67d1f'}}>
```

### 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`.
