我一直在尝试合并(连接)两个相同高度和宽度的mp4视频,但会出现一些错误。 代码是:

FFmpeg ffmpeg = FFmpeg.getInstance(EditVideoActivity.this);
            String list = generateList(new String[]{ActualVideoFile.getAbsolutePath(), path});
            try {
                ffmpeg.execute("ffmpeg -f concat -i " + list + " -c:v copy " + mergedVideo.getAbsolutePath(), new FFmpegExecuteResponseHandler() {
                    @Override
                    public void onStart() {
                        Log.e("Start", "Start");
                    }

                    @Override
                    public void onFinish() {
                        Log.e("FINISHED", "finish");
                    }


                    @Override
                    public void onSuccess(String message) {
                        Log.e("SUCCESS", message);
                    }

                    @Override
                    public void onProgress(String message) {
                        Log.e("PROGRESSSS", message);
                    }

                    @Override
                    public void onFailure(String message) {
                        Log.e("FAILURE", message);
                    }


                });
            } catch (FFmpegCommandAlreadyRunningException e) {
                e.printStackTrace();
                Log.e("FFMEG Exception", "" + e);
            }

logcat的:

而不是你当前的:

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class MyImageScript: MonoBehaviour {


    public int GetValue () {
        return 10;
    }
}

尝试使用它:

ffmpeg.execute("ffmpeg -f concat -i " + list + " -c:v copy " + mergedVideo.getAbsolutePath(), new FFmpegExecuteResponseHandler() {
