Self Hosted Canvas LMS cannot record or process videos without Kaltura

[tpokorra]

I have installed Canvas LMS on my own server. I also installed the Canvas RCE API Service.
I can upload images, but I still don't get the button "Upload/Record Media" in the RCE.
I can upload a video in the files area, but then I cannot use that video as a instructor on a page, because I get this message "Media file is processing. Please try again later."

This has been reported already multiple times in Github issues and in this community forum, but I would like to get an official answer.

Is it correct, that we need to use Kaltura to embed videos in Canvas?

This article makes it look as if you can upload and work with videos even without Kaltura:

Thank you for any insights!

DId you find out more on this?

We have a self-hosted site and we have been able to use videos in our courses without Kaltura in previous releases.

Thanks
