We already handle frame lost or corrupted buffer reported by drivers.
Perhaps your driver is reporting then the wrong way?

You may want to share somr more logs, as it's not clear what error your
driver reported. Consider looking at kernel trace first (out of scope for
GST ML) and the GST_DEBUG="v4l*:7,2"
