将音频添加到剪辑中

Question

我有以下代码，并且在视频输出中没有接收到声音。我用的是MoviePy软件包。

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

Answer 1

可能是缺少MP3编解码器吗；LAME"；等你的代码在Windows:上运行

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:UsersPublicMusicSample MusicKalimba.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")

这就是输出：trial.mp4

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

这是ffprobe在我的视频上的输出：

ffprobe z:trial.mp4

这可能是相关的，ffmpeg设置和moviepy的版本：在moviepy 中没有连接剪辑的音频

对于许多有这个问题的人，我发现，你只需要添加音频编解码器。

result.write_videofile("output.mp4"，fps=24，audio_dec='aac'(
