在 ubuntu 24.04.1 上使用 python 3.11.10 和 moviepy 1.0.3（在 Windows 10 上的 VirtualBox 7.1.3 中），我在加载视频剪辑时遇到问题。测试代码只是
from moviepy.editor import VideoFileClip
clip = VideoFileClip("testvideo.ts")
但是错误是

这里明确给出了时长为10分10.13秒。那么导致此错误/问题的原因可能是什么？
FFMPEG_BINARY
通常，您可以将其保留为默认值（“ffmpeg-imageio”），在这种情况下，imageio 将下载正确的 ffmpeg 二进制文件（首次使用时），然后始终使用该二进制文件。
第二个选项是“自动检测”。在这种情况下，ffmpeg 将是计算机上找到的任何二进制文件：通常是 ffmpeg（在 Linux/macOS 上）或 ffmpeg.exe（在 Windows 上）。
最后，您可以通过指定确切的路径将其设置为使用磁盘上特定位置的二进制文件。
使用此代码：
import os
os.environ["FFMPEG_BINARY"] = "/path/to/custom/ffmpeg"
其中路径是 ffmpeg 6.1.1-3ubuntu5 的路径，它可能在您的
PATH/usr/local/bin/bin/ffmpeg从错误中进行调试： moviepy 默认使用 ffmpeg 版本
4.2.2-static因此，使用能够处理 moviepy 中的 .ts 文件（即 6.1.1）的 ffmpeg 将是解决方案。
