基于Web的高性能遠程屏幕共享：jsmpeg-vnc
一個低延遲，高性能的服務器與客戶端屏幕共享實現，適用于任何現代瀏覽器。
Usage & Performance Considerations
jsmpeg-vnc.exe [options] <window name>
Options:
-b bitrate in kilobit/s (default: estimated by output size)
-s output size as WxH. E.g: -s 640x480 (default: same as window size)
-f target framerate (default: 60)
-p port (default: 8080)
Use "desktop" as the window name to capture the whole Desktop. Use "cursor"
to capture the window at the current cursor position.
Full Example:
jsmpeg-vnc.exe -b 2000 -s 640x480 -f 30 -p 9006 "Quake 3: Arena"
To enable mouse lock in the browser (useful for games that require relative
mouse movements, not absolute ones), append "?mouselock" at the target URL
i.e: http://<server-ip>:8080/?mouselockFor sharing the whole Desktop, Windows' Aero theme should be disabled as it slows down screen capture significantly. When serving a single window (e.g. games), Aero only has a marginal performance impact and can be left enabled.
Capturing and encoding 1920x1080 video narrowly amounts to 60fps on my system and occupies a whole CPU core. Capturing smaller windows significantly speeds up the process. Depending on your Wifi network quality you may also want to dial down the bitrate for large video sizes.
