将音频添加到剪辑

Question

我有以下代码并且在视频输出中没有收到声音。我正在使用 MoviePy 包。

from moviepy.editor import *  

picture = VideoFileClip("/Users/name/Desktop/trial.jpg", audio=False).set_duration(50)

txt_clip = TextClip("Hey",fontsize = 150, color='white')
txt_clip = txt_clip.set_pos('center').set_duration(10)

audio = AudioFileClip("/Users/name/Desktop/music.mp3").subclip(0,50)

video_with_new_audio = picture.set_audio(audio)

final_video = CompositeVideoClip([video_with_new_audio,txt_clip])

final_video.write_videofile("trial.mp4")

可能是什么问题？:c

会不会是缺少 MP3 编解码器、“LAME”等？您的代码适用于 Windows:

from moviepy.editor import *  

picture = VideoFileClip("img.jpg", audio=False).set_duration(20)

txt_clip = TextClip("Hey",fontsize = 150, color='white')
txt_clip = txt_clip.set_pos('center').set_duration(10)

audio = AudioFileClip(r"C:\Users\Public\Music\Sample Music\Kalimba.mp3").subclip(0,20)

video_with_new_audio = picture.set_audio(audio)

final_video = CompositeVideoClip([video_with_new_audio,txt_clip])

final_video.write_videofile("trial.mp4")

这是输出：trial.mp4

你能运行 ffprobe trial.mp4 或 ffmpeg -i trial.mp4 并显示输出吗？

这是我视频中 ffprobe 的输出：

ffprobe z:\trial.mp4

这可能与ffmpeg设置和moviepy版本有关：
