视频写入配置

#fourcc = cv2.VideoWriter_fourcc(*'XVID')

#out = cv2.VideoWriter('output_chinese.avi', fourcc, 20.0, (640, 480))

加载中文字体（Windows 示例）

font_path = "simhei.ttf" # 你可以换成系统其他中文字体

font = ImageFont.truetype(font_path, 32)

ip=input("输入对方ip地址:")

print("准备发送")

t=threading.Thread(target=fun)

t.start()

while(1):

ret, frame = ca.read()

if not ret:

break

转换为 PIL 图像对象

img_pil = Image.fromarray(cv2.cvtColor(frame, cv2.COLOR_BGR2RGB))

draw = ImageDraw.Draw(img_pil)

写入中文文本

draw.text((50, 50), text, font=font, fill=(255, 0, 0))

转回 OpenCV 格式

frame = cv2.cvtColor(np.array(img_pil), cv2.COLOR_RGB2BGR)

显示窗口

#cv2.imshow('Video with Chinese', frame)

写入视频文件

#out.write(frame)

zip_data=cv2.imencode('.jpg', frame, $int(cv2.IMWRITE_JPEG_QUALITY), 80$ ) $1$

buffer_data=zip_data.tobytes()

jj=s.sendto(zip_data,(ip,8000))

print(jj)

if cv2.waitKey(1) & 0xFF == 27: # ESC键退出

break

cv2.waitKey(1)
