我正在使用aeneas
的ffmpeg
python模块。我在dockerfile中安装ffmpeg
,如下所示:
RUN apt-get update && apt-get install -y ffmpeg
现在,当我运行该程序时,它失败并显示:
aeneas.ffprobewrapper.FFPROBEPathError: Unable to call the 'ffprobe' ffprobe executable : [Errno 2] No such file or directory: 'ffprobe'
和aeneas.audiofile.AudioFileProbeError: Unable to call ffprobe executable
。所以我的问题是,如何才能在Docker容器中成功使用ffmpeg
?我正在运行Ubuntu 16.04。 最佳答案
从Debian 9/10 / Ubuntu 上的docker容器中的源安装新的ffmpeg版本。
您可以将4.2.2版本替换为https://ffmpeg.org/releases/上的任何其他版本
