Quick Example

# pip install pyd2v
from pyd2v import D2V

# ...

# Choose Input File
input_file = "/home/user/Desktop/video.d2v"
# Parse Input File
d2v = D2V(filename=input_file)
# Print D2V Version and Settings Options, which will be shown with the accessible variable names.
print(d2v)
# Print Input Video Files
print(d2v.videos)
# Print Frame Rate
print(d2v.settings["Frame_Rate"])
# Print first frame data
print(d2v.data[0])

Accessible Variables

A successful D2V parse will result in the following options accessible from the D2V object.

  • 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.
