Build search and readable transcripts for conference videos

This is a Node application that processes caption files from conference videos to enable search and create readable transcripts.

The code could easily be adapted to work with caption files from other playlists.

Installation and usage

1. Clone or download the code.
2. Add your SRT caption files to the input directory. See get-youtube-captions.md for instructions on how to how to retrieve caption files for YouTube videos.
3. From a terminal cd to the src directory and run node index.js -s, optionally setting flags (see below). This creates HTML for readable transcripts (in the docs folder) and builds the search index if the -s flag is set.
4. Progress updates and errors are logged to the console.
5. When conversion is complete, view the results from index.html in the app directory, the directory used for GitHub Pages. This directory includes a CSS file and a JavaScript file to style the transcripts and enable interaction.

SRT and app directories

• When you clone the repo, the directories for the SRT caption files and the app contain sample files.

Known issues

Google Translate widget

This widget is no longer supported and the language selection popup is not laid out responsively.

Probably best to remove unless the layout can be fixed (others have tried!)
