我在使用FFmpeg剪切部分视频时遇到错误

以下是我的代码

String[] cmd = {"ffmpeg -ss 0 -i "+mPath+" -t 30 -c copy "+ (Environment.getExternalStorageDirectory().getabsolutePath()+"/sample.mp4")};executeCommand(cmd);

函数executeCommand

voID executeCommand(String[] cmd) {    try {        fFmpeg.execute(cmd, new FFmpegExecuteResponseHandler() {            @OverrIDe            public voID onSuccess(String message) {                Toast.makeText(VIDeoFullScreen.this, "finished :" + message, Toast.LENGTH_SHORT).show();            }            @OverrIDe            public voID onProgress(String message) {            }            @OverrIDe            public voID onFailure(String message) {                Log.e("Error",message);            }            @OverrIDe            public voID onStart() {            }            @OverrIDe            public voID onFinish() {            }        });    } catch (FFmpegCommandAlreadyRunningException e) {        e.printstacktrace();    }}

解决方法:

This is an answer to my own question

我的问题出在我传递的命令字符串数组中

This answer is to the people who all are facing the similar kind of issues with ffmpeg

使用ffmpeg时应该遵循的重要事项

>确保在正确的String Array中传递命令

String[] cmd = {"-ss", "0", "-i" ,input_vIDeo_path, "-t" ,"30", "-c", "copy",output_vIDeo_path};

>不要在传递的参数和标志中添加任何额外空格
{“ – c”错了}
>不要在cmd数组中传递ffmpeg
{“ffmpeg”错了}

希望这会对某人有所帮助
