Android 如何使用FFMPEG合并两个视频？

inputCode是执行字符串。

ffmpeg命令应为

String Tmp1 = Environment.getExternalStorageDirectory() + "/" + "scary.mp4";
inputCode = new String[]{FileUtils.getFFmpeg(getApplicationContext()),
                "-i", Tmp1, "-i", VideoPath, "-filter_complex",
                "[0:v][1:v]blend=all_mode='overlay':all_opacity=0.8[v_out]", "-map", "[v_out]", "-map", "0:a", "-strict", "-2", VideoPath};

---

输入和输出文件不相同

使用此命令成功地将文件完全边缘化

   String Tmp1 = Environment.getExternalStorageDirectory() + "/" + "scary.mp4";
    inputCode = new String[]{FileUtils.getFFmpeg(getApplicationContext()),
                    "-i", Tmp1, "-i", VideoPath, "-filter_complex",
                    "[0:v][1:v]blend=all_mode='overlay':all_opacity=0.8[v_out]", "-map", "[v_out]", "-map", "0:a", "-strict", "-2", "/sdcard/OutPutVideo.mp4"};

谢谢

您提供的代码有什么问题？交叉检查应保存输出的驱动器名称可能找不到ffmpeg目录，并且您为不允许的输入和输出传递了VideoPath我认为命令中存在一些问题，因为没有生成输出文件。你能检查一下这个命令吗@Vinesh ChauhanW/System.err:java.io.IOException:运行exec时出错。命令：[/data/user/0/photo.edit.scaryvideomaker/files/ffmpeg，-i，/storage/emulated/0/ThugsLifeVideoMaker/videofiles/TL1537877161938.mp4，-filter_complex，[0:v][1:v]blend=all_mode='overlay'：all_不透明=0.8[v_out]，-map，[v_out]，-map，0:a，-strict，-2，/sdcard/OutPutVideo.mp4]工作目录：null环境：nullhave you Initialize FFMPegeInputCode=new String[]{FileUtils.GetFFMPegetApplicationContext，-y，-i，InputPath1，-i，InputPath2，-strict，experimental，-filter_complex，[0:v]scale=480x640，setsar=1:1[v0]；[1:v]scale=480x640，setsar=1:1[v1]；[v0][0:a][v1:a]concat=n=2:v=1:a=1，-ab，48000，-ac，2，-ar，22050，-s，480x640，-r，30，-vcodec，mpeg4，-b，2097k，OutPutPath}；
