changing maximum number of uploaded slides & maximum file size

[Giannis Koutzamanis]

Hi!!!!!!!!!!!

I found out in your FAQs page the info about the maximum number of uploaded slides:
http://code.google.com/p/bigbluebutton/wiki/FAQ#Can_I_increase_the_100_page_limit_for_uploads?

We 're interested in increasing the maxNumPages and I'd like to know if it would be unsafe to do something like that.

The upper limit of 100 pages that you set by default, is a protection that has to do with the disk storage, for preventing presenters to upload large files?

Or is a limit appropriate for the BBB system, so it could convert and show the uploaded files without any problem?

The question is: if we change the maxNumPages, for example to 200 or 300, would this cause any trouble?

And another final question: the maximum file size of 30 mb has to do with the sum of the files uploaded in each session, or has to do with each uploaded file separately? Also, is it safe to change the client_max_body_size to more than 30m?

Thanx!

Hi Giannis,

> The upper limit of 100 pages that you set by default, is a protection that has to do with the disk storage, for preventing presenters to upload large files?

We added that limit a few years ago when we first made demo.bigbluebutton.org visible to the public.  Our intent was to prevent someone from uploading a 1000 page document and causing the file conversion to take many, many minutes.

The limit as arbitrary, and you can certainly increase it to 200 or 300.

> the maximum file size of 30 mb has to do with the sum of the files uploaded in each session, or has to do with each uploaded file separately?

Each uploaded file separately.  You can change it as well, you may encounter a time out issue if the user tries to upload a very large document over a very slow connection.  We haven't tried this as most documents are not very large, but if your going to increase the maximum file size, I would recommend testing it yourself first.

Regards,... Fred
