GStreamer is LGPL and many plugins are as well. An exception are
e.g. plugins of the gst-plugins-ugly module. For legal advice better

You can use the tee element to create branches in the graph. E.g.
camerabin is a high level element that uses one camera source and
e.g. shows the video on screen and records it at the same time.<br>

I am not following. A queue element could keep a backlog of frames,
but would *not* offer convenient random access.<br>
