This is a copy of gstrfbsrc.c from gst-plugins-bad, but using libvncclient instead of their custom rfbdecoder, which seems to result in better behavior with some servers.
The supported way to build this is via the
Nix package manager, through the
nix-remarkable
expressions. To build just this project via nix build from this
repo, download it into the pkgs/ directory of nix-remarkable.
For other systems, the commands needed to compile and link are relatively simple, and given in derivation.nix.
This module provides an rfbsrc GStreamer element. For example, if
the produced libgstrfbsrc.so is in result/lib, a VNC server from
localhost could be rotated right 90 degrees and connected to
video-conferencing software expecting 1280x720 YUV420 video on a
v4l2loopback device
/dev/video0 via the command:
GST_PLUGIN_PATH_1_0=result/lib gst-launch-1.0 rfbsrc host=127.0.0.1,port=5900 ! videoconvert ! videoflip video-direction=90r ! videoscale ! video/x-raw,format=I420,width=1280,height=720,pixel-aspect-ratio=1/1 ! queue ! v4l2sink device=/dev/video0
