A golang project, aim for stream one pc's active window or full screen (windows or linux) to another device as MJPEG over http or as flv over rtmp as soon as possible, it can be a broadcast service or a point to point service as you want, if you want to use tridef-3d but you don't have a professional VR head set, and you have a smart phone, I think you will like this application.
For using ScreenStreamer easily, you can use ScreenStreamerManager.
With rtmp, you should wait a few minutes, to get the video delay down to 500ms. With Windows this not work, With Windows, you can minimize the window temporarily and wait to the phone's screen stopped, then restore the window.

Build it
# need install libjpeg/libjpeg-turbo, on windows, need install mingw, libjpeg/libjpeg-turbo for mjpeg sudo apt-get install libjpeg-turbo8-dev # need install libav, on windows, need install mingw, libav for rtmp sudo apt-get install libav-tools libavcodec-dev libavformat-dev # create a workspace directory mkdir ./ScreenStreamer # enter the directory cd ./ScreenStreamer # clone the source code git clone [email protected]:fiefdx/ScreenStreamer.git src/ScreenStreamer # enter the project root directory cd ./src/ScreenStreamer # add the workspace directory and lib directory to GOPATH # export GOPATH=/path-to-workspace/ScreenStreamer:/path-to-workspace/ScreenStreamer/src/ScreenStreamer/lib # run . ./dev.sh can set the GOPATH too . ./dev.sh # build the mjpeg, it will produce binary executable files named "mjpeg" or "mjpeg.exe" go build ./cmd/mjpeg/mjpeg.go # build the rtmp, it will produce binary executable files named "rtmp" or "rtmp.exe" go build ./cmd/rtmp/rtmp.go # build the get_active_window, it can get current active window's id for ScreenStreamerManager go build ./cmd/get_active_window/get_active_window.go

Run it
# enter the project root directory cd ./src/ScreenStreamer # run mjpeg service ./mjpeg or .\mjpeg.exe # use a web browser or other video player, open http:https://host:port/mjpeg # run rtmp service ./rtmp or .\rtmp.exe # use a video player, open rtmp:https://host:port/live/screen

Stop it
# Use Ctrl+C at the terminal or just close the terminal -
Performance
Server side CPU: i5-6300HQ(20%) RAM: 12GB(very less) SYSTEM: Windows 10 Home As MJPEG: # mxplayer can't play mjpeg sometimes Client side PHONE: LG G3 PLAYER: mxplayer FPS: 25(the mxplayer play mjpeg as 25fps,so , I set it 20-24fps, more fps just get frame delay, and the window's size is (1280 * 720)) DELAY: <100ms(it's depend on your network and devices, my phone can's fully use 1000M wifi) As RTMP: Client side PHONE: LG G3 PLAYER: mxplayer FPS: 20(my laptop is 1920*1080 resolution, it can get 20fps in Windows 10, or 25fps in Xubuntu linux) DELAY: <500ms(it's depend on your network and devices, my phone and pc not powerful enough) Wifi: 1000M
