如何用python控制obs

想实现一个功能，用python控制虚拟摄像头软件obs，根据已知的图片文件路径，令摄像头显示该图片，并且随时可以根据图片路径更改显示。

该回答引用chatgpt:
要控制虚拟摄像头软件OBS并显示指定的图片，您需要使用Python和OBS提供的Python库obs-websocket-py。以下是实现该功能的基本步骤：

安装obs-websocket-py库

pip install obs-websocket-py

连接到OBS


import obswebsocket, obswebsocket.requests

# Connect to the OBS WebSocket server
client = obswebsocket.obsws("localhost", 4444, "password")
client.connect()

设置虚拟摄像头并获取虚拟摄像头源ID


# Set the virtual camera as the active scene
client.call(obswebsocket.requests.SetCurrentScene("Virtual Camera"))

# Get the source ID for the virtual camera
response = client.call(obswebsocket.requests.GetSourcesList())
for source in response.getSources():
    if source.getName() == "Virtual Camera":
        virtual_camera_id = source.getSourceId()
        break

加载图片并更新虚拟摄像头的源



import base64

# Load the image from file
with open("image_path.jpg", "rb") as f:
    image_data = f.read()

# Encode the image data as base64
image_base64 = base64.b64encode(image_data).decode("utf-8")

# Set the image as the virtual camera source
client.call(obswebsocket.requests.SetSourceSettings(virtual_camera_id, {"file": image_base64}))

根据需要更新图片并更新虚拟摄像头的源


# Load the new image from file
with open("new_image_path.jpg", "rb") as f:
    new_image_data = f.read()

# Encode the new image data as base64
new_image_base64 = base64.b64encode(new_image_data).decode("utf-8")

# Set the new image as the virtual camera source
client.call(obswebsocket.requests.SetSourceSettings(virtual_camera_id, {"file": new_image_base64}))

这些步骤将帮助您通过Python控制OBS，并根据需要更改虚拟摄像头的源。请确保已安装OBS软件，并已设置虚拟摄像头。
