How can I get to know whether a element get my data or not

[Ugly Face]

My mp4 file and the pipeline works well.

After add "gst_debug_set_threshold_for_name("h264parse", 4);" to my c code,
I get something interesting.

the h264parse seems dose not work properly as it fails to finish its task. I
do not know if info above will be help to give me some other advice . 

I do not think any words can be helpful to show my appreciation for your
help .
