HFT-Unity Video From Unity
This sample show one example of sending video from Unity to the phones. It does this in the simplest brute force method possible.
WebCamTexture is created. It's contents is read and scaled to some
smaller size. That smaller size is then sent to the phones. It it only
sent around 10fps.
Sending video is problematic at the moment. Ideally we'd use WebRTC but iOS (as of 8.1) doesn't yet support WebRTC. Video is normally sent as deltas from the previous frame along with various kinds of compression and motion info. That's to get the amount of data needed to a minimum.
This sample though just shows sending uncompressed data. Because it's uncompressed and because the data is so large you'll likely need to keep it small or lower the frame rate depending on the number of players that are receiving the video
NOTE: This is just the hft-unitysimple example with video tacked in. The video is not displayed in Unity. It is only displayed in controllers.
