This wiki show how debug a pipeline using the debug enable.
To debug a pipeline one easy way is enable the debug using gstd, next examples shows how to do it, and what is the expected output when some works good or fail.
pipeline_create p1 videotestsrc ! autovideosink pipeline_play p1 debug_enable true debug_threshold 6 debug_color true pipeline_create p playbin uri=file://tmp/video.mp4 pipeline_play p
Output when everything works good:

Output when something goes wrong:
