Running in Chrome before and after connecting:
See more screenshots here.
HTML5 Canvas (with createImageData): Chrome, Firefox 3.6+, iOS Safari, Opera 11+, Internet Explorer 9+, etc.
HTML5 WebSockets: For browsers that do not have builtin WebSockets support, the project includes web-socket-js, a WebSockets emulator using Adobe Flash. iOS 4.2+ has built-in WebSocket support.
See the more detailed browser compatibility wiki page.
Unless you are using a VNC server with support for WebSockets connections (such as x11vnc/libvncserver, QEMU, or PocketVNC), you need to use a WebSockets to TCP socket proxy. There is a python proxy included ('websockify').
Use the launch script to start a mini-webserver and the WebSockets
proxy (websockify). The
--vnc option is used to specify the location of
a running VNC server:
./utils/launch.sh --vnc localhost:5901
Point your browser to the cut-and-paste URL that is output by the launch script. Enter a password if the VNC server has one configured. Hit the Connect button and enjoy!
