我正在尝试为我的Android应用运行以下命令:
"ffmpeg -i /full/path.video.mp4 -ignore_loop 0 -i myGif.gif -filter_complex \"[0][1]overlay=0:H-100\" /full/path/videoWithGifOverlay.mp4"
但我收到了错误。
这是输出:

我正在尝试保存视频,经过录制后,上面有一个gif叠加。

如果你看一下FFmpeg android示例,你会看到它们将每个“”(空格)分开,所以不应该传递一个集成的字符串命令,你应该这样做:
String[] commands = new String[10];
commands[0] ="-i";
commands[1] = "/full/path.video.mp4";
...
