已经安装ffmpeg并将安装路径正确添加至系统变量，仍然运行错误- torio._extension.utils - DEBUG - Loading FFmpeg - torio._extension.utils - DEBUG - Failed to load FFmpeg extension.

相关文件是在的
ffmpeg路径也添加至系统变量中
我刚好解决这个问题，我发现如果我在Windows平台上不使用ctypes.CDLL强制加载动态库，就会报错找不到动态库，即使加到环境变量中也会报错 就是这个 2025-03-29 21:50:03,683 - torio._extension.utils - DEBUG - Failed to load FFmpeg extension. 解决方法：ctypes.CDLL(avcodec-60.dll) 直接加载ffmpeg的动态库，如果你不知道模块加载顺序、或者要加载什么动态库，就在所有module前加全部动态库
"""
Windows 平台的库加载器
"""
import ctypes
import os
from os import environ
def load_libraries():
"""加载 Windows 平台的 FFmpeg DLL 文件"""
ffmpeg_path = environ.get("FFMPEG_DLL_PATH")
dll_list = [
"avcodec-60.dll",
"avdevice-60.dll",
"avfilter-9.dll",
"avformat-60.dll",
"avutil-58.dll",
"swresample-4.dll",
"swscale-7.dll",
]
# 检查 FFmpeg 路径是否存在
if not os.path.exists(ffmpeg_path):
print(f"Warning: FFmpeg path {ffmpeg_path} does not exist")
return False
loaded_count = 0
for dll in dll_list:
dll_path = ffmpeg_path + dll
try:
if os.path.exists(dll_path):
ctypes.CDLL(dll_path)
loaded_count += 1
print(f"Loaded: {dll}")
else:
print(f"Warning: {dll_path} not found")
except Exception as e:
print(f"Error loading {dll}: {e}")
print(f"Successfully loaded {loaded_count}/{len(dll_list)} Windows DLL files")
return loaded_count > 0
类似这样，然后在 main.py 中执行load_libraries函数
https://github.com/wwbin2017/bailing/issues/52#issuecomment-2980427885 确实有用，终于解决了

大佬，我在树莓派上遇到同样的问题，请问要怎么解决？谢谢！
