Question

我使用 FFMPEG 从图像生成视频，但它总是需要相同的 FPS。如何更改生成视频的 FPS？

    cmd = new String[5];
                cmd[0] = "-f";
                cmd[1] = "image2";
                cmd[2] = "-i";
                cmd[3] = Environment.getExternalStorageDirectory()+"/Photo Story/image%d.jpg";
                cmd[4] = PathVideo + "/"+ FileName;

Answer 1

利用

cmd = new String[7];
cmd[0] = "-f";
cmd[1] = "image2";
cmd[2] = "-framerate";
cmd[3] = "25"; // <-- replace with fps
cmd[4] = "-i";
cmd[5] = Environment.getExternalStorageDirectory()+"/PhotoStory/image%d.jpg";
cmd[6] = PathVideo + "/"+ FileName;

替换 25与帧率的变量或值。
