描述
我在 debian 75 (wheezy) 上运行 motion 3.2.12 标准包。检测到动作、触发事件，并将图片保存在正确的文件夹中，正如预期的那样。
另一方面，由于此错误，motion 无法使用 ffmpeg 录制电影

我们可以看到无法打开 avcodec。我找到了类似的帖子这里Debian 团队没有给出令人信服的答案，因为用户已经通过原始的 Scratch/安装解决了这个问题。
但问题仍然存在
注意：我使用 ffmpeg 24/24 存档视频流并将它们转换为多种 Web 输出格式，没有任何问题。它工作正常。
我想知道由于我根据这个“错误”发现了大量帖子，此功能是否仍然可用？
有什么办法可以解决这个问题吗？
