There are some tools here that may be useful towards this goal, such as BBB-Render:
“Scripts to convert a BigBlueButton recording into a single video file”
If you’re building in automation for exporting recordings, it would be awesome to be able to do a single-click export to a PeerTube instance. Ideally where would be options for a one-off manual export, and a regular, automated export.
For example, let’s say an org uses meet.coop for a monthly public meeting, which they have a dedicated BBB room for. They host a PT instance, with a channel specifically for recordings of those meetings. The first time they export a recording from the dedicated room, they’re asked for the information necessary to upload the file (eg URL of the PT instance), and redirected to PT to login and give the BBB room publishing access to the correct PT channel.
They can then click either ‘publish this recording’, OR, ‘publish every recording from this room’, to choose between manual and automated upload. If they choose manual upload, the next time they export a recording, the previous details will be pre-filled, so if they just want to go ahead and upload to the same channel, they can just click ‘publish this recording’ again.
