Apparently the video decoding and other client-side stuff is done purely in JavaScript (and in particular using WebGL), no <video> tag or plugins or anything like that. I presume that all the server-side stuff is still native code.

I'd still like to see a demo page with their JavaScript decoder.

Are you sure it is not just as simple as opening up a websocket and pipe the frame data as texture data directly into the webgl instant?

No, there is a full DCT decoder in ORBX.js, the encoder is built into the Amazon AMI, and can use CPU or GPU for encoding (the GPU encoder is pure OpenCL - so one day ORBX.js could support encoding in the browser through WebCL). If you send raw data down to the browser, you would need a 1 GB connection . We are targeting 4G/LTE speeds at 8-12 Mbps for HD @ 60 hz, with support going to 1-3 Mbps for 1024x768 @ 30- 60 hz..

How would video compression work in that case?
