UltraVNC SC

[larytet]

Hello,

I am trying to run UltraVNC SC_II_RC23 with https://kanaka.github.io/noVNC/

I have to patch the noVNC to allow accept the connections from the VNC server instead of connected by itself.
The patches in noVNC are:
https://github.com/larytet/websockify/c ... 7e04a68aa3
https://github.com/larytet/noVNC/commit ... 47f7f87f7c

I am getting

Code: Select all

Disconnected: unsupported encoding 16"

in the WEB browser. I have looked in the source code and I see that this is probably rfbEncodingZRLE.

I do not quite understand how the vncencodemgr.h chooses the encoder when the VNC server connects to the client. Can I force different encoding, for example rfbEncodingTight(7)?

Thank you.

More research:

* All SingleClick patches are under SINGLECLICKULTRA
* Message MENU_ADD_CLIENT_MSG causes adding a new client to the server in single click mode

How the "dummy" chooses the encoding?

[larytet]

I still can not understand how the server in single click mode decides to use ZRLE and where I can patch the code and force, for example, raw enconding

This is the full log until connection:

Patch the function vncEncoding::SetEncoding() use HexT encoder in the case rfbEncodingTigh.
Works with noVNC client.
