Readme

resync-srt
Streaming command and module that reads SRT data and a time offset and outputs the resultant SRT.

example

To use resync-srt as a command, install it using npm:
$ npm install -g resync-srt

You can feed it either files or raw data from stdin:
$ resync-srt 500
1
00:00:00,000 --> 00:03:00,000
Hello, warld!
^D

which will output
1
00:00:00,500 --> 00:03:00,500
Hello, warld!

If this data was in an .srt file you could also use the filename as the first argument:
$ resync-srt foo.srt -1000

usage

resync-srt [FILE] MILLISECOND-OFFSET

api

var resync = require('resync-srt')

resync(offsetMs)

resync-srt exports a single method, which accepts an offset in millseconds. Positive values push the timestamps forward in time, while negative values push them backward.
This returns a Transform stream: reading SRT data and outputting SRT data that has been time-shifted.

streaming

This is still using subtitle.js which doesn't offer a streaming interface. This module merely wraps its functionality into a convenient interface. See the issue.
