本文介绍如何使用webpmux工具对webp动图进行解序列帧和重新合并，参考了Google的webp官方文档。

import java.io.IOException;
import java.io.InputStream;
import java.util.Objects;

public class WebpMux {

    private final static String dir = "/Users/wangduanqing/Desktop/test/";

    public static void main(String[] args) throws IOException {
        String filePath = dir + "koubi.webp";
        InputStream is = Runtime.getRuntime().exec("webpmux -info " + filePath).getInputStream();
        String[] rows = new String(is.readAllBytes()).split("\n");
        int total = Integer.parseInt(rows[3].replace("Number of frames: ", ""));
        System.out.println("total frames: " + total);
        WebpMuxConfig[] webpMuxConfigs = new WebpMuxConfig[total];
        for (int i = 5; i < total + 5; i++) {
            webpMuxConfigs[i - 5] = splitRow(rows[i]);
        }
        for (int i = 0; i < total; i++) {
            Runtime.getRuntime().exec("webpmux -get frame " + (i + 1) + " " +
