FFMPEG将-ss和-to设置为字符串 [英] FFMPEG set -ss and -to with string

问题描述

我知道我可以用 -ss 开始，以 -to 结尾，但有人可以帮助我格式化以下内容，以便我可以输入 -ss 和 -to 一个字符串？

I know I can set the start with -ss and end with -to but can someone please help me to format the following so that I can enter the -ss and -to with a string?

-ss 来自

String start = editStart.getText().toString();

和 -to 来自

and -to to come from

String end = editEnd.getText().toString();

这是我要编辑的ffmpeg字符串，我已经输入了 -ss 和 -to 以显示我想要上述字符串的位置。

Here is my ffmpeg string I want to edit, I have entered -ss and -to to show where I want the above strings to be.

String s = "-i" + " " + mVideoUri.toString().replace("file:///", "") + " -filter_complex [1:v][0:v]scale2ref=iw:ih[ovr][base];[ovr]colorchannelmixer=aa=0.7[ovrl];[base][ovrl]overlay[v] -ss -to -map [v]" + directoryToStore + "/" + FileName + mp4;

String[] arguments = s.split(" ");

ExecuteFFMPEG(arguments);

推荐答案

确定，以便您的起点和终点：

Ok so you get your start and end point from:

String start = editStart.getText().toString();  
String end = editEnd.getText().toString();

所以，而不是分割参数，而是改为：

So instead of splitting the argument do this instead:

String[] s = {"-i" ,mVideoUri.toString(),"-filter_complex","[1:v][0:v]scale2ref=iw:ih[ovr][base];[ovr]colorchannelmixer=aa=0.7[ovrl];[base][ovrl]overlay[v]","-ss","start","-to","end","-map","[v]",directoryToStore+"/"+"output.mp4"};
ExecuteFFMPEG(s);
