我有2个ffmpeg命令,我分别执行它们,它们起作用,但是我想一次又一次执行它们。该怎么做?

ffmpeg -i 1.mp4 -i logo.png -filter_complex "overlay=main_w-overlay_w-20:20" -codec:a copy 2.mp4

ffmpeg -i 2.mp4 -i picture.png -filter_complex "overlay=10:10" -codec:a copy 3.mp4

使用:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".HomeScreenActivity"

    >
    <android.support.v4.widget.DrawerLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/HomeScreenDrawerLayout"
        >

    </android.support.v4.widget.DrawerLayout>

    <FrameLayout

        android:layout_height="match_parent"
        android:id="@+id/homeScreenframeLayout"

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/homeScreenBottomNavigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:layout_alignParentLeft="true"

        app:menu="@menu/bottom_navigation"
        android:background="?android:attr/windowBackground"
        >

    </android.support.design.widget.BottomNavigationView>

</RelativeLayout>
