pidgin video chat

[Amadeus W.M.]

Does anyone know how to do video chat in pidgin? I can't figure it out 
for the life of me. I click on a contact name and the chat window opens. 
Then, under Conversation -> Media I have 3 options: Audio call / Video 
call / Audio and video call. But all are inactive (grayed out) and so 
they can't be selected. Does this mean that pidgin has been compiled in 
Fedora without audio/video support? 

I am, however able to configure the Voice/Video Settings by going to 
Tools -> Plugins -> Voice/Video Settings, then click on the "Configure 
Plugin" button. So pidgin does see my camera and microphone. But what 
else do I need to be able to actually use them? 

I've searched the web for this, of course, and I couldn't find a 
definitive answer. All information is outdated, or for other 
distributions, or simply vague. For instance:

https://developer.pidgin.im/wiki/vv

or the user guide (which is really a FAQ):

https://developer.pidgin.im/wiki/Using%20Pidgin



Do I need to recompile pidgin with some non-free codecs enabled? 

Thanks for any help!
