如何在Windows中将Webcam与Python和Pygame结合使用？ vidcap.Error：无法设置捕获分辨率

Question

因此，我在Pygame中下载了Video Capture的窗轮。但是，当我创建网络摄像头实例时，出现以下错误。在我开始实现相机模块之前，代码运行良好。我看到的答案很少，它们来自2013年。我希望Pygame从那时起在Windows上会有更多的改进，但是最有可能是由我引起的。有什么建议吗？

import pygame
import pygame.camera

pygame.init()
# https://www.lfd.uci.edu/~gohlke/pythonlibs/#videocapture need to get the VideoCapture whl
pygame.camera.init()

webcam = pygame.camera.Camera(0, (640, 480), "RGB")
webcam.start()

pygame.display.set_caption("S.H.A.N.E.")
icon = pygame.image.load("SHANE pic.jpg")
pygame.display.set_icon(icon)
background = pygame.image.load("SHANE pic.jpg")
# (WIDTH, HEIGHT)
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))

running = True
while running:
    # STARTING POINT (L/R, T/B), ENDING POINT (L/R, T/B)
    screen.fill((0, 0, 0))
    img = webcam.get_image()
    screen.blit(img, (0, 0))

    pygame.display.flip()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

这是我遇到的错误。

Traceback (most recent call last):

webcam = pygame.camera.Camera(0, (640, 480), "RGB")

File "C:\Users\Notebook\AppData\Local\Programs\Python\Python37-32\lib\site-<packages\pygame\_camera_vidcapture.py", line 60, in __init__
   self.dev.setresolution(width, height)
vidcap.Error: Cannot set capture resolution.

Answer 1

webcam = pygame.camera.Camera("/dev/video0",(640,480))

您没有将相机的坐标/大小/比例放置在放置它们的位置，这是为文件输入保留的。干杯!文件：https://www.pygame.org/docs/tut/CameraIntro.html
