如何安装旧版本的ffmpeg？

Question

我在使用当前版本的 ffmpeg 时遇到问题，它以我的客户不支持的格式将 .mp3 转码为 .wavs。

如何安装这个版本？

ffmpeg version 0.7.3-4:0.7.3-0ubuntu0.11.10.1, Copyright (c) 2000-2011 the Libav developers
  built on Jan  4 2012 16:08:51 with gcc 4.6.1

我试图解决的问题是将 .mp3 转码为 .wav。我们的客户有一个识别服务，可以从 .wav 中确定歌曲。当我传递 ffmpeg 生成的 .wav 时

exec ("ffmpeg -ss $start -t $duration -i $shellArgSongPath -f wav -ar 44100 somefile.wav");

我收到“不支持音频格式”的消息

我的猜测是用于从 .mp3 转码到 .wav 的默认编解码器已更改。有人知道以前的版本是什么吗？

This program is not developed anymore and is only provided for compatibility. Use avconv instead (see Changelog for the list of incompatible changes).

根据我们的评论风暴，我假设 libav 中存在回归，或者您的应用程序中存在错误，给您提供“不支持音频格式”消息。您可以尝试编译 ffmpeg（来自 FFmpeg 项目，而不是 libav）。根据我的经验，失败ffmpeg时通常会起作用。avconv这将创建 ffmpeg 的“本地”版本，因此它不会干扰存储库中的 ffmpeg/avconv：

sudo apt-get install build-essential yasm
cd
wget -O ffmpeg.tar.gz "http://git.videolan.org/?p=ffmpeg.git;a=snapshot;h=HEAD;sf=tgz"
tar xzvf ffmpeg.tar.gz
cd ffmpeg-HEAD-*
./configure
make

现在尝试 ffmpeg。请注意./前面的内容ffmpeg，此示例假设输入文件位于您的主目录中。输出将放置在您的主目录中：

cd ~/ffmpeg-HEAD-*
./ffmpeg -i ~/input.mp3 ~/output.wav

如果这有效，您可以考虑实际替换 libav 并安装 ffmpeg：How To Compile FFmpeg and x264 on Ubuntu。
