comtel2000 / jfxvnc Goto Github PK

Hello, I'm trying connect to server from jfxvnc-app. But connection closed after handshake without error.
another clients work fine with my vnc server. For example, Vernacular VNC. That's wrong in this connectiion?
log app:

It can't work in 16bpp,the view dosen't show,how to fix it?

hhh,please put some comments,tks

Hello,
I tried to run jfxvnc against a x11vnc server.
By using the actual github version the server quits the communication with the log entry:

15/11/2017 12:00:58 Pixel format for client 192.168.99.23
15/11/2017 12:00:58   32 bpp, depth 24, little endian
15/11/2017 12:00:58   uses a colour map (not true color).
15/11/2017 12:00:58 rfbSetTranslateFunction: client has colour map but 32-bit - can only cope with 8-bit colour maps

So I tried to force the jfxvnc viewer into RGB_555 pixel format e.g. by trying to set DEFAULT_PIXELFORMAT in org.jfxvnc.ui.control.VncImageView.java:47 to PixelFormat.RGB_555.

When I do this the server assumes

15/11/2017 12:15:33 Pixel format for client 192.168.99.23:
15/11/2017 12:15:33   16 bpp, depth 16, little endian
15/11/2017 12:15:33   true colour: max r 255 g 255 b 255, shift r 16 g 8 b 0

which looks fine - however jfxvnc throws an IndexOutOfBoundsException :

00:39:02.693 [vnc-connection-17] DEBUG org.jfxvnc.net.rfb.codec.ProtocolHandler - request full framebuffer update

Interesting as well that the Apps Info Panel shows still a Depth from 24 (32bpp)...

I tried to force RGB_555 on some more places where it looks like it is set/get - but no success yet.

Is there a way to force the complete App to be on RGB_555 ? (that could be as well some feature...)

Many Thanks
Kind Regards

The README makes no mention of how to run the program. I see you worked on a fork of TigerVNC; is there any similarity?

There must be a messed up DNS entry somewhere. If I click on the "View on Github" link on http://www.jfxvnc.org/ then the github page does not appear. If I instead enter the GitHub link (https://github.com/comtel2000/jfxvnc) into the URL address widget the proper page appears.
