Subject: libvncserver: add config option for tightpng encoding support
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d4a54ed5157472f8e3c72f58bd79ab014845f03f;p=buildroot.git

libvncserver: add config option for tightpng encoding support

TightPNG encoding speeds up HTML5 based VNC clients like noVNC.
libvncserver enables this encoding if both libpng and jpeg libraries
are available.

[Thomas: rewrap Config.in help text.]
