First of all, you need to know the ID of the BigBlueButton meeting you have recorded. Let's say, the BBB presentation link is https://conf.fsfe.org/playback/presentation/2.3/876393061e41e72de6bba58123451ee5a970d503-1649332654305. In this case, 876393061e41e72de6bba58123451ee5a970d503-1649332654305 is the ID you need to provide.

Also, you need to have ruby installed. There are also some ruby libraries necessary that may not be available on your system by default. Typically, they should be available in your distribution's repository, e.g. ruby-loofah.

Then, it is recommended to clone this repository and work within this directory.

1. Download all required parts

With the first command, you download all required parts:

ruby download_client.rb -i 876393061e41e72de6bba58123451ee5a970d503-1649332654305

By default, the recording is searched on the FSFE's BBB instance. If you want to download a recording from another instance, provide e.g. -h other.bbb-host.com.

2. Export to a single video file

The second command compiles everything into one file. Depending on the recording length and your computing power, this may take a couple of minutes:

ruby export_presentation.rb -i 876393061e41e72de6bba58123451ee5a970d503-1649332654305

If this is done, you will find the final file in presentation/876393061e41e72de6bba58123451ee5a970d503-1649332654305/.

Customisation

The export_presentation.rb file contains a number of variables that can configure the actual display of the file, e.g. the size or whether to show the chat. This has to be done manually for now.
