ffmpeg的：输出到同一个文件夹递归输入源？ [英] ffmpeg: Output to the same folder as source with recursive input?

问题描述

我有很多的GIF我想转换成许多子目录webms的，我有这个脚本，将做到这一点，但它会输出到脚本所在的目录：

I have a lot of gifs I want converted to webms in many sub directories, and I have this script which will do it, but it will output to the directory where the script is located:

for /r %%a in ("*.gif") do ffmpeg -i "%%a" -c:v libvpx -crf 12 -b:v 4000k "%%~na.webm"
pause

我已经尝试了一堆东西，但我无法弄清楚如何让输出在同一个子目录土地作为输入文件，所以我可以保持文件夹结构。

I've tried a bunch of things, but I can't figure out how to get the output to land in the same sub directory as the input file so I can maintain the folder structure.

编辑：这是我使用Windows批处理文件

it's a Windows batch file I'm using.

推荐答案

您缺少为输出文件名两个命令修饰符。

You are missing two command modifiers for your output filename.

"%%~dpna.webm"
