Cloud Video Intelligence API error 400 & 504 - python-3.x

Question

When I tried to call Cloud Video Intelligence API to detec subtitle in local video file.It always returned error 400 or 504, but use gas is fine.I have tried to adjusted timeout in Cloud Video Intelligence config but it still show error 400 with invalid argument.
this is my python code for detecting video subtitle:
"""This application demonstrates detection subtitles in video using the Google Cloud API.
Usage Examples:
use video in google cloud storge:
python analyze.py text_gcs gs://"video path"
use video in computer:
python analyze.py text_file video.mp4
"""
