Video ffmpeg上的合成与大小不匹配

我试着拍摄3个视频和一幅图像，并制作10秒的合成，大致如下：

这是到目前为止我得到的命令。（我把它格式化了一点，这样更容易阅读）

在前3个过滤器上，我尝试填充/裁剪视频，以匹配512x288 在下一个过滤器上，将图像裁剪/填充到640x874 在接下来的2个过滤器中，我在顶部和中部视频中添加了一些填充，共5个像素

左栏的总高度应为

288*3+5*2=874

但当我运行此命令时，会出现以下错误：

输入1高度874与输入0高度872不匹配

那两个像素到哪里去了？如果我用图像代替左边的视频，效果很好。只有在一些视频中，它似乎以某种方式破坏了额外的2像素

发生了什么事？我怎样才能修好它

更新

我想出来了。显然，填充不接受奇数，所以当填充到5时，我只是填充到4。

粘贴完整的控制台输出。但也可以尝试将

setsar

s放在

scale

s完成之前。没用……啊。如果在填充之前添加

format=yuv444p

，它应该可以处理奇数。由于您使用的是堆栈过滤器，因此必须将其添加到所有视频输入中。
