Hi @mokkin, Thank you for your suggestion - I wasn't aware of this docker installation. It certainly is a must-have once the script is done.
@mokkin Hi,
I have BBB 2.3 installed with docker (bbb-install-script) and it is no problem to copy the *.rb files ind the mentioned folder.
Hi Daniël,
I have a BBB 2.3 docker install, same as @mokkin and @blu-IT mentioned. I just copied the two ruby scripts into the mentioned folders and made them executable. No further tweaking. Yet no luck with my first conversion trial... (Please look at the very extensive message below).
Any suggestions?
Regards,

Hi @RPHr5TyZ, Thanks for sharing the logs. A few questions:
Was Inwinteren - ZwarteBij.org
part of the input somehow?
From the console output it looks like something is wrong with the linebreaks in FFmpeg command. Can you double-check that the script was copied over correctly?
Would you be able to share the link of the recording here so I can debug the problem?
Thanks in advance
Hi @danielpetri1
I downloaded the code with wget on my server, unzipped and copied the files to the indicated folders. (What could have gone wrong with that?) Double-checked with Beyond Compare just now and everything looks identical with the downloaded code on my laptop.
"Inwinteren - ZwarteBij.org" is the title of a lecture, and this is the link: ---
Thank you very much for your help! I really appriciate that!
Regards,
Peter
@RPHr5TyZ Bedankt! I could reproduce the problem, the "-" and ' ' in the title of the lecture were making the video renderer think it's a new command. Escaping it made it work, I'll push the fixed code soon after some more tests.
Here's your video file: ----
Let me know when you got it and I'll delete the link then. Cheers!
@danielpetri1
Great! I downloaded the file and watched for a few seconds. Looks promising! You can delete the link.
Sleep well!
Closing since it is compatible with the Docker install.
@danielpetri1
... I'll push the fixed code soon after some more tests. ...
Any indication when?
Best regards,
Peter
@RPHr5TyZ change line 591 to the following:
render << "-metadata title=\"#{meeting_name}\" #{BENCHMARK} #{@published_files}/meeting-tmp.mp4"
And make rendering quicker by setting
CHAT_CANVAS_WIDTH = 640
Both in export_presentation.rb
@danielpetri1
I'll give it a try. Many thanks!!
@danielpetri1
I'll give it a try. Many thanks!!
@danielpetri1
Code change successful!
We are using BBB with the docker script. Unfortunately I cannot simply add the files there. Please try to integrate it in the docker script.
