It appears that the nvv4l2decoder is broken in the latest release (32.4.3):

Does NOT work:
gst-launch-1.0 -v rtspsrc location=rtsp://admin:admin123@192.168.1.108:554 ! rtph264depay ! queue ! h264parse ! nvv4l2decoder ! filesink location=test.mp4

If you switch to omxh264dec, it DOES work:
gst-launch-1.0 -v rtspsrc location=rtsp://admin:admin123@192.168.1.108:554 ! rtph264depay ! queue ! h264parse ! omxh264dec ! filesink location=test.mp4

It may be a known issue with h264 parsing with nvv4l2decoder. You may try this post.

Hi,
The issue is under investigation. Please try rtph264depay ! nvv4l2decoder as a quick fix.
