Sample apps for generating composed files from OpenTok individual stream archives:

• composer.js - This command-line script takes an archive.zip file as the input and outputs a composed file with the names of each individual displayed under them. It uses the connection data of each participant as the name. You can provide the connection data when you create a token for each participant. For more information, have a look at the OpenTok documentation.

  NOTE: Up to Node 12 supported.

• BARC - A batch archive processor with support for CSS-based layout management.

You need to make sure you have installed FFmpeg with all of the dependencies. On Mac OS you do this with:

brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass --with-libquvi --with-libvorbis --with-libvpx --with-opus ----with-x264

Then checkout this repo and run npm install.

  Usage: ./composer.js [options] -i <zipFile>

  Options:

    -h, --help             output usage information
    -V, --version          output the version number
    -i, --input <zipFile>  Archive ZIP file
    -f, --format [type]    Output format [webm,mp4]

The ZIP file is the output of the OpenTok individual stream archiving API.
