如何使用 ffmpeg 在视频上按秒叠加多幅图像

我在视频上叠加图像，我浏览了很多链接，但没有得到我想要的结果，

我有多个图像名称框架0.jpg 框架1.jpg 框架2.jpg等等

所以我尝试用这个命令

String[] complexCommand = {"-y", "-i", videoPath, "-i", dir.getAbsolutePath() + "/"
 + filePrefix + "1" + fileExtn ,"-filter_complex", "[1][0]scale2ref[i][m];[m][i]overlay[v]" ,
"-map", "[v]", "-map",  "0:a?", "-ac", "2", dir.getAbsolutePath() + "/out.mp4"};



ffmpeg -y -i /storage/emulated/0/DCIM/Camera/VID_20171211_105946.3gp -i 
/storage/emulated/0/Pictures/Video/frame1.jpg -filter_complex 
[1][0]scale2ref[i][m];[m][i]overlay[v] -map [v] -map 0:a? -ac 2 
/storage/emulated/0/Pictures/Video/out.mp4

输出：成功在视频上叠加单幅图像

我需要在视频上每秒叠加图像，我的图像序列是 frame1.jpg、frame2.jpg 等等

尝试输出是视频中每秒添加的新帧。

例子 ：

第二个1：frame1.jpg

第二个2：frame2.jpg

第二个3：frame3.jpg

第二个4：frame4.jpg

/storage/emulated/0/Pictures/Video/frame2.jpg
/storage/emulated/0/Pictures/Video/frame3.jpg

如果你的图像被命名为序列，你可以使用

ffmpeg -y -i /storage/emulated/0/DCIM/Camera/VID_20171211_105946.3gp -framerate 1 -i 
/storage/emulated/0/Pictures/Video/frame%d.jpg -filter_complex 
[1][0]scale2ref[i][m];[i]fps=25[i];[m][i]overlay[v] -map [v] -map 0:a? -ac 2 
/storage/emulated/0/Pictures/Video/out.mp4
