我得到以下错误ffmpeg.
打开输出流#0的编码器时出错:0 - 可能是不正确的参数,如bit_rate,rate,width或height
ffmpeg -f image2 -i %05d.jpg -vcodec libx264 foo.mp4
我很确定我之前已经使用过这个确切的命令而且一切都很好.这是我的终端输出.任何帮助,将不胜感激.
$ ffmpeg -f image2 -i %05d.jpg -vcodec libx264 foo.mp4

您必须裁剪输入图像,以便将得到的宽度和高度除以2
裁剪过滤器:
-vf "crop=in_w-1:in_h"
$ ffmpeg -f image2 -i %05d.jpg -vf "crop=in_w-1:in_h" -vcodec libx264 foo.mp4
UPD
我们可以为一般情况编写公式,这导致了偶数方面
$ ffmpeg -f image2 -i %05d.jpg -vf "crop=((in_w/2)*2):((in_h/2)*2)" -vcodec libx264 foo.mp4
