ximagesrc

This element captures your X Display and creates raw RGB video. It uses the XDamage extension if available to only capture areas of the screen that have changed since the last frame. It uses the XFixes extension if available to also capture your mouse pointer. It supports handling of mouse and keyboard events. By default it will fixate to 25 frames per second.

Applications are expected to call XinitThreads() before any other threads are started. For use in gst-launch-1.0 or other GStreamer command line applications it is also possible to set the GST_XINITTHREADS=1 environment variable so that XInitThreads() gets called when the plugin is loaded. This may be too late in other use case scenarios though, so applications should not rely on that.

Example pipelines

 gst-launch-1.0 ximagesrc ! video/x-raw,framerate=5/1 ! videoconvert ! theoraenc ! oggmux ! filesink location=desktop.ogg

Encodes your X display to an Ogg theora video at 5 frames per second.
