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

求大佬帮忙解答

大佬这个问题解决了吗

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

#52 (comment) 确实有用，终于解决了

conda install -c conda-forge ffmpeg=6.1

大佬，我在树莓派上遇到同样的问题，请问要怎么解决？谢谢！
