flask mp4 file stream overwrite

[oes5756]

I want to stream new videos on the same 5000 port every time
Only the 888.mp4 is fixed and cannot be overwritten

my code

from flask import Flask, send_file

app = Flask(name)

@app.route('/')
def get():
return send_file("888.mp4")

if name == "main":
app.run(debug=True, host='0.0.0.0', port=5000)
