如何安装旧版本的 ffmpeg？

我在使用当前版本的 ffmpeg 时遇到了问题，它将 .mp3 转码为我的客户端不支持的格式的 .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 中识别歌曲。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”

我猜想用于从 .mp3 转码为 .wav 的默认编解码器已经改变。有人知道上一版本中是什么吗？

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 中存在回归或您的应用程序中存在错误，导致您收到“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，因此它不会干扰您从存储库获取的 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./之前的ffmpeg，此示例假定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：如何在 Ubuntu 上编译 FFmpeg 和 x264。

答案2

我也有同样的问题，因为我想从 ffmpeg 4.2.2 降级到 3.4.6。以下是我操作的方法：

因为这个答案，我了解了apt policy ffmpeg，所以我运行它并看到：

vagrant@vboxHomestead:~/Code/$ apt policy ffmpeg
ffmpeg:
  Installed: 7:4.2.2-0york0~18.04
  Candidate: 7:4.2.2-0york0~18.04
  Version table:
 *** 7:4.2.2-0york0~18.04 500
        500 http://ppa.launchpad.net/jonathonf/ffmpeg-4/ubuntu bionic/main amd64 Packages
        100 /var/lib/dpkg/status
     7:3.4.6-0ubuntu0.18.04.1 500
        500 http://archive.ubuntu.com/ubuntu bionic-updates/universe amd64 Packages
        500 http://security.ubuntu.com/ubuntu bionic-security/universe amd64 Packages
     7:3.4.2-2 500
        500 http://archive.ubuntu.com/ubuntu bionic/universe amd64 Packages

我知道我想降级到7:3.4.6-0ubuntu0.18.04.1。

https://www.linuxuprising.com/2019/02/how-to-downgrade-packages-to-specific.html非常有帮助。

于是我就跑了sudo apt install ffmpeg=7:3.4.6-0ubuntu0.18.04.1。

浏览软件包档案http://www.packages.ubuntu.com/。
我发现您要求的版本在里面梦境存储库。

只需下载并安装该.deb软件包及其依赖项（如果需要）。
