Build a single video from recorded presentation

[Greg Link]

Hello, is it possible to build a single video from a recorded session?

I mean when you watch a recorded session it's ok, but you can't send the file to someone as it is several video, audio and text files.

Thanks

[Fred Dixon]

Hi Greg,

There is work underway in the upcoming BigBlueButton 2.6 to add a new recording format that creates a single video file.  See

  https://docs.bigbluebutton.org/2.6/new.html#recording-in-mp4-format

Regards,... Fred

Nice... in the while, can I get the "time offests" of the videos and audio to build a video with ffmpeg ?

Sorry I just saw that I can download the webcams.mp4 file to have the video with audio of the webcams, without the presentation and texts, but that's enough for me thanks.

Cordialement, Grégory Defaisse

hi  Grégory Defaisse, did you configure something related to video recording after installing bbb because I am getting all the recordings (screenshare, webcam and presentation) as plain white with not changes in any configuration files

I tried both webm and mp4, but none worked for me.

Installed bbb 2.5.6 through this " wget -qO- https://ubuntu.bigbluebutton.org/bbb-install-2.5.sh | bash -s -- -v focal-250 -s bbb.example.com -e not...@example.com -a -w "

Thank you for your consideration

[Gregory D.]

No I'm using default configuration fro recordings

[Aman Patyal]

same here, I nearly searched everywhere, why there is a white recording of everything in all the modes( full or small)?, but maybe no one got this error except me (even after fresh setup of bbb 2.5.6 many times).

Due you have any idea, why this is happening.

Thank you very much for your response.

[Les Piech]

this works if you need something now..  https://github.com/manishkatyan/bbb-mp4

Hi.
In the mean time you could capture your screen while the actual BBB record system is playing back the recorded meeting you need. (SimpleScreenRecorder or Kazam if you are using Linux)
Other option could be this project: https://github.com/danielpetri1/bbb-recording-exporter (It works for BBB 2.5)
Regards.

Thank you I'll try that !
