A set of tools (API + script) to read, write and transform captions from/to many formats

Project Description

Introduction

This package is a set of tools to transform captions from one format to another. You will find Writer and Reader for each format and a script if you want to use it in command line.

Supported Format:

  • sbv Reader and Writer
  • srt Reader and Writer
  • ttml Reader and Writer
  • transcript Reader and Writer

How to use (API)

You can read the provided unittest to have complete examples:

from captionstransformer.sbv import Reader
from captionstransformer.ttml import Writer
from StringIO import StringIO
test_content = StringIO(u"""
0:00:03.490,0:00:07.430
>> FISHER: All right. So, let's begin.
This session is: Going Social

0:00:07.430,0:00:11.600
with the YouTube APIs. I am

""")
reader = Reader(test_content)

captions = reader.read()
len(captions) == 4
first = captions[0]
type(first.text) == unicode
first.text == u">> FISHER: All right. So, let's begin.\nThis session is: Going Social\n"

# next get a writer
filelike = StringIO()
writer = Writer(filelike)
writer.set_captions(captions)
text = writer.captions_to_text()
text.startswith(u"""<tt xml:lang="" xmlns="http://www.w3.org/ns/ttml"><body><div>""")
writer.write()
writer.close()

About Formats

This quite hard to find simple documentation about existing caption format. Here is a set of existing named caption format:

SubViewer (SUB):

      <p xml:id="subtitle1" begin="0.76s" end="3.45s">
        It seems a paradox, does it not,
      </p>
      <p xml:id="subtitle2" begin="5.0s" end="10.0s">
        that the image formed on<br/>
        the Retina should be inverted?
