Calvin Walton 3c1a9cd7c4 RAP: Use "asetpts=N" in ffmpeg audio processing 
There's an issue sometimes where when processing the audio from a
desktop sharing file, the STARTPTS value is invalid somehow, and this
results in bad timestamps in the output stream. Depending on the
selected codec/container combination, this might result in errors such
as spam of the message:

Application provided invalid, non monotonically increasing dts to muxer in stream

or simply a hang during processing.

Since we're already using aresample in async mode to correct timestamp
gaps, we can use "asetpts=N" here to simply set the audio frame pts
values to the sample number directly, giving proper monotonic timestamps
with no gaps.

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 18.04 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 https://docs.bigbluebutton.org/.
