vMix 15

This is a video mixing/recording/streaming/broadcasting application. It works really smooth on Windows (small memory footprint, small CPU footprint - comparing with other video streaming softwares, uses lots of graphic's card features like CUDA, OpenCL and just lots of 3D and other features, etc), although it doesn't have any linux variant. It uses Adobe® Flash® Media Live Encoder for encoding the video (although it has some other codecs, if the users wants to, even FMLE being, still, if not the very best, one of the very best). It mixes video input signals (video files, powerpoint files, camera inputs, etc), and then transcodes them (FMLE usually, sure) to whichever the user chooses: harddisk (the "Record" option), some URL (even multi-URL streaming, like streaming to multiple URLs, or just mainstream/substream, etc. It uses the "Stream" option.) streaming, etc. It can also work (and should work) together with some other small apps that help the vMix application, like the "Desktop Capture" software (which streams the local user's desktop to some other vMix instance which can be on some other PC on the LAN or wherever on the network/internet/etc).
