  you don't need to implement html5 I think. openQA already has the live view with some javascript running. so you could grab keystrokes there and send it to the server

      if you ever used the live view in a slow network, you realize we do need VNC :)

  https://github.com/kanaka/noVNC/wiki/KeyEvents - having the keys handled by a library sounds like a good idea, it's a mess in javascript

  Incomplete and hit by roadblock: * worked initially on gtk-vnc and gvnccapture (screenshot code using gtk-vnc), which was crashing due to TLS/X509 authentication. * discovered using gtk-vnc was not a good idea, as you don't have access to VNC stream. * read extensive RFB protocol documentation: https://github.com/rfbproto/rfbproto * then research various VNC capture solutions: - vnc-reflector: http://sourceforge.net/projects/vnc-reflector/ - vnc2flv http://www.unixuser.org/~euske/python/vnc2flv/ - rfbproxy (and rfbplaymacro): http://rfbproxy.sourceforge.net/ and http://cyberelk.net/tim/rfbplaymacro/

  • spend a lot of time to work on rfbproxy code (which is quite old) to get it to accept VNC session with recent server and client (due to some encoding / protocol evolution not supported by rfbproxy)
  • played with wireshark and learned how to get it to decode VNC protocol (not fully automatic by default)
  • fixed rfproxy to properly record key stroke and mouse button press, in VNC proxy mode
  • couldn't get rfbproxy to export at the same time the screen frames, because it doesn't handle latest VNC encoding used by Tigervnc / Xvnc.
  • the only way to have rfbproxy to handle decoding VNC stream into frames is to use it in "passive recording" mode (ie non proxy mode) but in that case, you miss all keystroke or mouse clics.
  • roadblock, I don't see how to progress further with the current solution.

  Current fixed code for rfbproxy is available at

  https://github.com/fcrozat/rfbproxy/tree/tigervnc

  Not sure if it is possible to continue any further with my choice. Maybe a better solution could be to re-implement rfbproxy with libvncserver/libvncclient ( https://libvnc.github.io/ )
