Calvin Walton 1268753519 Fix io deadlock in recording scripts process execution utilities 
The previous implementation of the BigBlueButton.execute method runs the
process with separate stdout and stderr streams. It first reads all of
the output from stdout, then reads all of the output from stderr.

This can cause a deadlock if the process writes a lot of data to stderr.
The IO buffer for stderr could fill, blocking progress. But since it
hasn't closed stdout, the ruby script is still waiting on a read to
stdout.

Switch to an execution method (using IO.popen) that allows combining
stdout and stderr into a single stream, eliminating the issue.

BigBlueButton

BigBlueButton is an open source web conferencing system.

BigBlueButton supports real-time sharing of audio, video, slides (with whiteboard controls), chat, and the screen. Instructors can engage remote students with polling, emojis, multi-user whiteboard, and breakout rooms.

Presenters can record and playback content for later sharing with others.

We designed BigBlueButton for online learning (though it can be used for many other applications). The educational use cases for BigBlueButton are

  • Online tutoring (one-to-one)
  • Flipped classrooms (recording content ahead of your session)
  • Group collaboration (many-to-many)
  • Online classes (one-to-many)

You can install on a Ubuntu 16.04 64-bit server. We provide bbb-install.sh to let you have a server up and running within 30 minutes (or your money back :-).

For full technical documentation BigBlueButton -- including architecture, features, API, and GreenLight (the default front-end) -- see http://docs.bigbluebutton.org/.
