我有一个 Rails 应用程序，并将 cookie_store 更改为 active_record_store，但是当我在 ffmpeg 中使用视频转换器时，出现此错误
也许有人可以帮我解决这个问题？

我不认为你选择的饼干店与此有任何关系。发生这种情况是因为您选择了具有此特定输入尺寸 (1280x720) 的视频文件。 错误是：
[libx264 @ 0xa1105e0] height not divisible by 2 (720x405)
该网站上有很多关于此错误的问题，但最终归结为一个简单的答案：“确保编码的图片具有均匀的宽度和高度”。在您的情况下，输出图片尺寸（720x405）是从您的站点代码传递下来的，因此您需要在那里修复它。
当指定新的高度/宽度时，你使用-1让它缩放尺寸，但它选择了一个奇数，然后抱怨它是奇数。显然是一个小错误，但通过用偶数替换 -1 可以轻松修复。
