嗨呀嗨呀,最近重温了一档综艺节目 至于叫什么 这里就不细说了
老是看着看着就会看到一堆马赛克,由于太好奇了就找了一下原因,结果是因为某艺人塌房了…虽然但是 看综艺的时候满影响美观的
咳咳,这里我可不是来教你们如何解码的,我是来教你们如何打码的,嘿嘿
那今天就在这分享一下 视频打码功能如何用python来实现
环境咱们还是使用 Python3.8 和 pycharm2021 即可
手动安装一下 cv2 模块 ,pip install opencv-python 安装
安装遇到报错,可以私信我
我们需要安装一下 ffmpeg 音视频转码工具
import cv2
import face_recognition # 人脸识别库 99.7% cmake dlib face_recognition
import subprocess
def video2mp3(file_name):
"""
:param file_name: 视频文件路径
:return:
"""
outfile_name = file_name.split('.')[0] + '.mp3'
cmd = 'ffmpeg -i ' + file_name + ' -f mp3 ' + outfile_name
print(cmd)
subprocess.call(cmd, shell=False)
# 源码领取:309488165 ### def mask_video(input_video, output_video, mask_path='mask.jpg'): """ :param input_video: 需打码的视频 :param output_video: 打码后的视频 :param mask_path: 打码图片 :return: """ # 读取图片 mask = cv2.imread(mask_path) # 读取视频 cap = cv2.VideoCapture(input_video) # 视频 fps width height v_fps = cap.get(5) v_width = cap.get(3) v_height = cap.get(4)
设置写入视频参数 格式MP4
画面大小
size = (int(v_width), int(v_height))
fourcc = cv2.VideoWriter_fourcc('m', 'p', '4', 'v')
输出视频
out = cv2.VideoWriter(output_video, fourcc, v_fps, size)
已知人脸
known_image = face_recognition.load_image_file('tmr.jpg') biden_encoding = face_recognition.face_encodings(known_image)[0] cap = cv2.VideoCapture(input_video) while (cap.isOpened()): ret, frame = cap.read() if ret: # 检测人脸 # 人脸区域 face_locations = face_recognition.face_locations(frame) for (top_right_y, top_right_x, left_bottom_y, left_bottom_x) in face_locations: print((top_right_y, top_right_x, left_bottom_y, left_bottom_x)) unknown_image = frame[top_right_y - 50:left_bottom_y + 50, left_bottom_x - 50:top_right_x + 50] if face_recognition.face_encodings(unknown_image) != []: unknown_encoding = face_recognition.face_encodings(unknown_image)[0] # 对比人脸 results = face_recognition.compare_faces([biden_encoding], unknown_encoding) # [True] # 贴图 if results == [True]: mask = cv2.resize(mask, (top_right_x - left_bottom_x, left_bottom_y - top_right_y)) frame[top_right_y:left_bottom_y, left_bottom_x:top_right_x] = mask out.write(frame) else: break
