如何抓取从视频音频？ [英] How to rip the audio from a video?

问题描述

我在Ubuntu和想一个MP4视频转换为MP3音频文件，但无法弄清楚如何。我尝试安装的ffmpeg，但它没有连接code中的MP3。我读过的GStreamer做它，但我无法弄清楚如何。我的GStreamer和python安装。我可以用Python程序，但我不能从源代码或更高级别的命令行的东西超级舒服编译软件。我只知道在命令行上的基础知识。

解决方案

  mplayer的＆LT;＆录像档案GT; -dumpaudio -dumpfile out.bin
 

它会复制原始音频流，那么这应该很容易使用SOX，瘸腿的，VLC或诸如此类的东西转化。 VLC具有良好的转换选项，以及 - 它运动的GUI。我不知道刚才提取音频，但它应该是肯定的能够的吧

I am on ubuntu and want to convert a mp4 video to an mp3 audio file but can't figure out how. I tried installing ffmpeg but it failed to encode the mp3. I've read the gstreamer does it but I can't figure out how. I have gstreamer and python installed. I can program with python, but am not super comfortable compiling software from source or any higher level command line stuff. I only know the basics on the command line.

解决方案

mplayer <videofile> -dumpaudio -dumpfile out.bin

it will copy the raw audio stream, that should then be easily converted using sox, lame, vlc or whatnot. VLC has nice conversion options as well - and it sports a GUI. I don't know about extracting just the audio, but it should sure be capable of it
