【FFMPEG】"width / height not divisible by 2" 解决方法

解决方法一:计算出宽高大小


出现该错误的原因是在于:视频的宽度必须是32的倍数,高度必须是2的倍数


解决方法:


if (screen_width % 32 != 0)

{

screen_width = screen_width / 32 * 32;

}

 

if (screen_height % 2 != 0)

{

screen_height = screen_height / 2 * 2;

}


解决方法二:  scale="854:-2"    https://ffmpeg.org/

Instead of

'scale=-2:min(1080\,ih)'

use

'scale=-2:min(1080\,if(mod(ih\,2)\,ih-1\,ih))'

It will check if ih is divisible by 2, and if not, it will decrease it by 1.
