gst: libcamerasrc: Prevent src task deadlock on exhausted buffer pool
Allow GstLibcameraPool to notify the source when a new buffer has become available in a previously exhausted buffer pool. This can be used to resume a src task that got paused because it couldn't acquire a buffer. Without this change the src task will never resume from pause once the pool gets exhausted. To trigger the deadlock (it doesn't happen every time), run: gst-launch-1.0 libcamerasrc ! queue ! glimagesink Signed-off-by: Jakub Adam <jakub.adam@collabora.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
