android - 寻找适用于 Android 的 FFmpeg 包装器

Question

嘿 stackoverflow 各位，

我需要使用 FFmpeg 将一段视频和几张照片组合起来创建一个视频。我已经设法在我的系统上编译 FFmpeg 并静态链接它。现在，我正在为 Android 寻找利用 ffmpeg 完成任务的包装器/库。

我尝试过的:

• Guardian 项目代码，很棒的 api，简单而漂亮，但是当运行 createSlideshowFromImagesAndAudio 时，我得到了一个很好的返回码，但我的设备上从未创建过该文件(如果您有使用此代码的经验，我得到的返回码是 11) .
• JCodec，慢如 hell 。
• FMJ，不支持我需要的功能。

所以问题仍然存在，Android 有哪些好的 FFmpeg 包装器？

Answer 1

这是 FFMPEG 的 Wrapper，它工作得很好:你必须按照这些步骤为 android 制作 FFMPEG Wrapper。你必须创建几个类，如下所示:

ShellUtils.java

package com.example.processvideo;

public class ShellUtils {

    //various console cmds
        public final static String SHELL_CMD_CHMOD = "chmod";
        public final static String SHELL_CMD_KILL = "kill -9";
        public final static String SHELL_CMD_RM = "rm";
        public final static String SHELL_CMD_PS = "ps";
        public final static String SHELL_CMD_PIDOF = "pidof";

        public final static String CHMOD_EXE_VALUE = "700";

    public static boolean isRootPossible()
    {

        StringBuilder log = new StringBuilder();

        try {

            // Check if Superuser.apk exists
            File fileSU = new File("/system/app/Superuser.apk");
            if (fileSU.exists())
                return true;

            fileSU = new File("/system/bin/su");
            if (fileSU.exists())
                return true;

            //Check for 'su' binary 
            String[] cmd = {"which su"};
            int exitCode = ShellUtils.doShellCommand(cmd, new ShellCallback ()
            {

                @Override

                    //System.out.print(msg);

                }

            }, false, true);

            if (exitCode == 0) {

将所有文件放在一起后，如果要将帧合并到视频中，请调用此函数，如下所示

  FFMpegVideoProcess.createFramesinFolder(this,DIR_IN_WHICH_YOU_WANT_TO_KEEP_FRAMES, "frame_%03d.jpg");
        FFMpegVideoProcess.mergeFramesIntoVideo(args1,DIR_IN_WHICH_YOU_WANT_TO_KEEP_FRAMES/frame_%3d.jpg",argN...);
