videoStatusUrl = f"https://www.pearvideo.com/videoStatus.jsp?contId={contId}"

headers = {

    "Referer": url
}

resp = requests.get(videoStatusUrl, headers=headers)
dic = resp.json()

srcUrl = dic['videoInfo']['videos']['srcUrl']
systemTime = dic['systemTime']
srcUrl = srcUrl.replace(systemTime, f"cont-{contId}")
