代碼指令bilibili去水印

以下是使用Python和OpenCV實現Bilibili視頻去水印的示例代碼，分為兩種方案：

方案一：基于ROI區域覆蓋（簡單版）

```python

import cv2

import os

import numpy as np

def remove_watermark(input_path, output_path, watermark_x=0, watermark_y=0, watermark_w=200, watermark_h=50):

讀取視頻

cap = cv2.VideoCapture(input_path)

if not cap.isOpened():

print("無法打開視頻文件")

return

 獲取視頻參數
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))
frame_count = int(cap.get(cv2.CAP_PROP_FRAMECount))
fourcc = cv2.VideoWriter_fourcc('mp4v')
創建視頻寫入器
out = cv2.VideoWriter(output_path, fourcc, 30.0, (width, height))
設置水印區域（右下角固定位置示例）
watermark_roi = (width watermark_w, height watermark_h, watermark_w, watermark_h)
try:
ret = True
while ret:
ret, frame = cap.read()
if not ret:
break
應用ROI覆蓋
frame[watermark_roi[1]:watermark_roi[1]+watermark_roi[3],
watermark_roi[0]:watermark_roi[0]+watermark_roi[2]] = np.zeros((watermark_h, watermark_w, 3), dtype=np.uint8)
保存處理后的幀
out.write(frame)
cap.release()
out.release()
print(f"去水印成功，輸出文件：{output_path
