I was in a similar need and accomplished the same. There are two ways in which you can do this. I would like to share the simpler one first.

首先,将你的照片重新命名为数字序列。例如,Ig1.jpg, img2.jpg, img3.jpg,... 之后,你可以操作:
Run this program programmetcally ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg

从方案上管理,

Use the following code:

void convertImg_to_vid()
{
    Process chperm;
    try {
        chperm=Runtime.getRuntime().exec("su");
          DataOutputStream os = 
              new DataOutputStream(chperm.getOutputStream());

              os.writeBytes("ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg
");
              os.flush();

              chperm.waitFor();

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

开始这样做。我将帮助你。最好
