Do GStreamer handle loss of key frames (H264)?

Do you have any advice from where should I start looking it? I think we
could add an option (disabled by default) to check for picture loss in
rtph264depay or h264parse to make it "implementation agnostic", so one
could use it for avdec_h264 or other decoders.
