> The GStreamer single stream test uses the following pipeline:
>
> libcamerasrc ! videoconvert ! fakesink
>
> The videoconvert element isn't useful as the data is thrown away by the
> fakesink anyway. We can shorten the pipeline to
>
> libcamerasrc ! fakesink
>
> to save CPU time and to avoid depending on the gstreamer1.0-plugins-base
> package to run the unit tests.
>
> The test could be further simplified by replacing
> gst_parse_bin_from_description_full() with gst_element_factory_make(),
> now that we only add one element to the bin. The extra cost incurred by
> the bin only impacts initialization time, and using a bin will make it
> easier to add other elements in the future if needed. Keep the bin, and
> only drop the videoconvert element.
