[libcamera-devel] [PATCH v1 16/23] gst: libcamerasrc: Push segment event

[Nicolas Dufresne]

From: Nicolas Dufresne <nicolas.dufresne at collabora.com>

Now that we have stream-start and caps, we can now push a segment event to
announce what time will our buffer correlate to. For live sources this is just
an open segment in time format.
