Unfortunately streamoff does not flush the events, and this can cause all sort of issues. Flush events on capture queue. We also return GST_V4L2_FLOW_RESOLUTION_CHANGE in case a resolution change was seen. This allow skipping streamon(capture) on flush, which could lead to a configuration miss-match, or failure if the buffers aren't of the right size.
