f1324f9cb0 videotestsrc: Document the num-buffers property 
It's not obvious from the existing docs that this option exists, nor
that it can be used to give a pipeline an exact length in video frames.

a47881100d videotestsrc: Avoid overflow calculation 
n_frames could end up being quite big (potentially up to G_MAXINT64). Which
would result in overflowing 64bits when multiplying it by GST_SECOND.

Instead move GST_SECOND to the num argument

4fdb5ab675 videotestsrc: Protect videoinfo with object lock 
The videoinfo is set in the streaming thread, but can be read by any
thread from the various queries, so protect it with the object lock.

the output is anything than a mono or single-eye
left/right view.

99f4899491 videotestsrc: Add options to make ball pattern based on system time, and invert each second. 
This adds some extra options that affect pattern=ball mode, allowing the
animation to be synced to running time or wall-time clock for comparing
sync across different instances / pipelines / machines.

Also added is the ability to invert the rendering colours every second,
and some different ball motion patterns.

with no further detail won't create a framerate field. If it's
not in the caps, don't fixate it, just set it to 30/1

386206e627 videotestsrc: keep track of the correct running time after renegotiations 
Need to store the old running time and frame numbers when renegotiating and
start from 0 again when a new caps is set, preventing that framerate changes
cause timestamping issues.

For example, if a stream pushed 10 buffers on framerate=2/1, its
running time will be 5s. If a new framerate of 1/1 is set, it would
make the running time go to 10s as it would count those 10 buffers
as being sent on this new framerate.

Fixes camerbin unit test.
