有没有python虚拟摄像头的sdk？可以通过编程来修改虚拟摄像头的输出内容，比如图片、视频等媒体？
网友回复
pyvirtualcam可以实现
安装
pip install pyvirtualcam
示例
import pyvirtualcam
import numpy as np
with pyvirtualcam.Camera(width=1280, height=720, fps=20) as cam:
print(f'Using virtual camera: {cam.device}')
frame = np.zeros((cam.height, cam.width, 3), np.uint8) # RGB
while True:
frame[:] = cam.frames_sent % 255 # grayscale animation
cam.send(frame)
cam.sleep_until_next_frame()
播放到摄像头
# This script plays back a video file on the virtual camera.
# It also shows how to:
# - select a specific camera device
# - use BGR as pixel format
import argparse
import pyvirtualcam
from pyvirtualcam import PixelFormat
import cv2
parser = argparse.ArgumentParser()
parser.add_argument("video_path", help="path to input video file")
parser.add_argument("--fps", action="store_true", help="output fps every second")
parser.add_argument("--device", help="virtual camera device, e.g. /dev/video0 (optional)...点击查看剩余70%
