2. Basic

3. QuickStart

All the componets listed below, will be open source by time.

cge

The Cloud Gaming Engine. A precompiled binary is here.

You can launch cge directly, which will apply the following options:

audio-bitrate: 128000
audio-codec: libopus
bind-address: ::
control-port: 8080
donot-present: false
enable-nvenc: true
keyboard-replay: none
stream-port: 8080
video-bitrate: 1000000
video-codec: h264
video-gop: 180
video-preset: llhp
video-quality: 23

Run cge --help to see all options:

Usage:
  -h [ --help ]                  produce help message
  --audio-bitrate arg (=128000)  set audio bitrate
  --audio-codec arg (=libopus)   set audio codec, can be one of {libopus, opus,
                                 aac}
  --bind-address arg (=::)       set bind address for listening, eg: 0.0.0.0
  --control-port arg (=8080)     set the UDP port for control flow
  --donot-present arg (=0)       Tell cgh don't present
  --enable-nvenc arg (=1)        Enable nvenc
  --keyboard-replay arg (=none)  keyboard replay method, can be one of {none,
                                 cgvhid}
  --stream-port arg (=8080)      set the websocket port for streaming, if port
                                 is 0, disable stream out via network. Capture
                                 and encode picture directly at startup but not
                                 on connection establishing, and never stop
                                 this until cge exit. stream port is not same
                                 as control port, this port is only for media
                                 output.
  --video-bitrate arg (=1000000) set video bitrate
  --video-codec arg (=h264)      set video codec, can be one of {h264, h265}
  --video-gop arg (=180)         set video gop
  --video-preset arg
  --video-quality arg (=23)      set video quality, lower is better, available
                                 range is 0-51, 0 is lossless

You can press Ctrl+C to stop it gracefully.

cgh

Some hook dlls for capturing pictures from D3D game.

Download here

cgi

A tool for injecting hook dll into game process.

Allowed options:
  -h [ --help ]              Produce help message
  -d [ --dynamic ] arg       Use dynamic injecting
  -e [ --exec ] arg          Path of the executable
  -a [ --arg ] arg           Arguments of the executable
  -c [ --cd ] arg            Current directory for the executable
  -i [ --imagename ] arg     Image name of the process being injected.
  -w [ --wait ] arg (=1,000) Wait before injecting. unit: ms
  --lx86 arg                 Path of x86 library path
  --lx64 arg                 Path of x64 library path

cgvhid

Cloud gameing Virtual HID driver. For replaying controller event on server. Download here

cgvidd

Cloud gameing Virtual Indirect Display Driver. For capturing screen on server.

video_source

A tool for testing. Download here. Just run it, and it will generate simple pictures and write them as video frames to shared memory, then notify cge to fetch. You can use cgc to see these pictures.

cgc

A testing version client to work with cge. Download h264 version here and h265 version here.

Usage:
  --server (=127.0.0.1) set server address
  --port (=8080)        set server port
  --hw_decode           hardware decoder, only support d3d11va now.

cgs

A WebRTC server works together with cge, to serve web clients.

4. Setting Up Your Build Environment

4.1 VS2019

Install VS2019 with ATL, CLang.

CLang/LLVM x64 is also needed, while VS may only has CLang x86.

4.2 Boost

Install Boost and set BOOST_ROOT environment variable to install directory. Details

Boost compile command:

.\b2 --address-model=64 runtime-link=static

4.3 FFmpeg

Put FFmpeg header files in deps\include, and the libs in deps\lib.

4.4 SDL

Put SDL2 header files in deps\include, and the libs in deps\lib.

The same as SDL_ttf 2.0 and SDL_net 2.0.

4.5 WDK

Required by cgvhid, cgvidd.

5. Building and Testing

Open each solution file with VS, and press F7.

Testing steps:

Run cge on server.
Run video_source on server.
Run cgc --server=<server_address> on anther PC as long as it can access the server over the network.

Test with games:

Assume you want to test USF4.

Install cgvhid on server.
Run cge --keyboard-replay=cgvhid on server.
Run cgi -d true -e SSFIV.exe -i SSFIV.exe --lx86 .\d3d9yuv.dll on server.
Run cgc --server=<server_address> on anther PC as long as it can access the server over the network.

Note that only support D3D9 games now, will support D3D11 games soon.
