In Japan, Ubuntu20.04 LST release 24-Apr-2020(JST)
I tried to install AVideo and AVideo-Encoder next URL
https://github.com/WWBN/AVideo/wiki/How-to-install-LAMP,-FFMPEG-and-Git-on-a-fresh-Ubuntu-18.x-for-AVideo-Platform-version-4.x-or-newer
But many modle not found.(For example php-txt)
When do AVideo and AVideo-Encoder support Ubuntu20.04 LST ?
I've tested it just today , and works perfectly .
You can ignore :
sudo apt install php-mbstring php-gettext
sudo phpenmod mbstring
sudo systemctl restart apache2
Work fine
PS: Forgot to say that you will need _php 7.4_ not 7.2
I installed AVideo fine.
But AVideo-encoder did not install finish.

I clicked "instal now"

I wait long time but It did not finish.
What do I check ?
the patch to AVideo maybe is not correct
Isn't it http://192.168.1.155/AVideo ?
Stream's URL http://192.168.1.155/AVideo

Encoder's URL http://192.168.1.155/AVideo-Encoder
(Under 18.04 http://192.168.1.153/AVideo and http://192.168.1.153/AVideo-Encoder/
Your suggestion about 2weeks ago)

As you can see here , you're poiting your streamer site to be http://192.168.1.155/ ( and that's wrong )
Your streamer site should be http://192.168.1.155/AVideo not http://192.168.1.155/
I am sory. I miss type streamer's URL. Please see next picture.
Stramer's URL http://192.168.1.155/AVideo

Use that "http://192.168.1.155/AVideo" in the AVideo streamer Site URL" box on the encoder page. You filled in only "http://192.168.1.155/".
