pgsreader

Read Presentation Graphic Stream (.SUP) files and provide python objects for parsing through the data

Example:

from pgsreader import PGSReader
from imagemaker import make_image

# Load a Blu-Ray PGS/SUP file.
pgs = PGSReader('mysubtitles.sup')

# Get the first DisplaySet that contains a bitmap image
display_set = next(ds for ds in pgs.iter_displaysets() if ds.has_image)

# Get Palette Display Segment
pds = display_set.pds[0]
# Get Object Display Segment
ods = display_set.ods[0]

# Create and show the bitmap image
img = make_image(ods, pds)
img.save('my_subtitle_image.png')
img.show()

# Create and show the bitmap image with swapped YCbCr channels 
img = make_image(ods, pds, swap=True)
img.save('my_subtitle_image.png')
img.show()

# Retrieve time when image would have been displayed on screen in milliseconds:
timestamp_ms = ods.presentation_timestamp

Extremely alpha, issues and suggestions welcome!
