My little video chat code is about ready for testing. I put the user's video and controls on the left, everyone else's videos on the right, and haven't added any bells or whistles beyond muting video and/or audio across the platform, and also the ability to handle JWTs.
Meanwhile, this agora code is available in UE starting at 4.27, I think. Please do NOT add video chat to your RPG. I'm begging you.
Besides, based on their fees, less than a minute into a super-popular MMORPG, you'd owe enough to buy a Twitter.
"AAAAAAAARRRRRRRRGGGGGGGGHHHHHHHH!"
"Jeez! What's wrong?"
"I opened a video chat inside of 'DungeonSlaughter II - Revenge Of The Bloody Stump,' and then Billy opened a video chat."
"So?"
"It keeps rebooting."
