python - 如何在python中使用ffmpeg合并音频和视频文件？

Question

我需要在 python 3.7 中使用 ffmpeg 合并音频和视频，你能帮我解决这个问题吗？

在这里我使用了代码:

from pathlib import Path
glob_path = Path(r"D:\t")
file_name = [str(pp) for pp in glob_path.glob(r'**/*.mp4')]
print(file_name)

video_stream = ffmpeg.input(file_name[0])
audio_stream = ffmpeg.input(file_name[1])
print(video_stream)
print(audio_stream)
ffmpeg.output(audio_stream, video_stream, 'out.mp4').run()

我得到了这个错误

['D:\\t\\audio.mp4', 'D:\\t\\video.mp4']
input(filename='D:\\t\\audio.mp4')[None] <b0ebefda3dca>
input(filename='D:\\t\\video.mp4')[None] <388c87446fd1>

似乎找不到其中一个文件。最好的办法是检查两个文件是否都存在于指定位置。
