Android FFMPEG java concat多個文件

[英]Android FFMPEG java concat multiple files

 原文  2015-07-11 17:01:19  5   1    java/ android/ cordova/ video/ ffmpeg

問題描述

我正在使用cordova-plugin-video-editor庫的fork：

https://github.com/jbavari/cordova-plugin-video-editor/pull/13

在這里使用android-ffmpeg-java庫：

https://github.com/guardianproject/android-ffmpeg-java

開箱即用的cordova插件示例非常適合使用以下代碼對單個視頻進行編碼： 

File tempFile = File.createTempFile("ffmpeg", null, appContext.getCacheDir());
FfmpegController ffmpegController = new FfmpegController(appContext, tempFile);

TranscodeCallback tcCallback = new TranscodeCallback();

Clip clipIn = new Clip(videoSrcPath);
Clip clipOut = new Clip(outputFilePath);
clipOut.videoCodec = "libx264";
clipOut.videoFps = "24"; // tailor this to your needs
clipOut.videoBitrate = 512; // 512 kbps - tailor this to your needs
clipOut.audioChannels = 1;
clipOut.width = outputWidth;
clipOut.height = outputHeight;
clipOut.duration = videoDuration;
ffmpegController.processVideo(clipIn, clipOut, true, tcCallback);

這將在此處調用android-ffmpeg-java代碼：

https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/FfmpegController.java#L225

他們在這里有一個多文件concat測試示例：

https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/test/ConcatTest.java#L16

所以我修改了cordova插件代碼以匹配示例： 

ArrayList<Clip> listVideos = new ArrayList<Clip>();

Clip clip = new Clip();
clip.path = new File(videoSrcPath).getCanonicalPath();
ffmpegController.getInfo(clip);
clip.duration = 5;
listVideos.add(clip);

Clip clip2 = new Clip();
clip2.path = new File(videoSrcPath2).getCanonicalPath();
ffmpegController.getInfo(clip2);
clip2.duration = 5;
listVideos.add(clip2);

Clip clipOut = new Clip();
clipOut.path = new File(outputFilePath).getCanonicalPath();
ffmpegController.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false, new ShellUtils.ShellCallback() {
    @Override
    public void shellOut(String shellLine) {
        System.out.println("fc>" + shellLine);
    }
    @Override
    public void processComplete(int exitValue) {
        if (exitValue < 0)
            System.err.println("concat non-zero exit: " + exitValue);
    }
});

但是，運行時出現錯誤：

我不確定為什么會顯示“不是目錄”？ 由於文件是在上一步中創建的，因此確定有效嗎？

好的，我有一個使用以下代碼的工作版本：

VideoEditor.java第10行 

import java.util.ArrayList;

VideoEditor.java第22行 

import org.ffmpeg.android.ShellUtils;

VideoEditor.java第99行 

// intro
final File inFile = this.resolveLocalFileSystemURI(options.getString("fileUri"));
if (!inFile.exists()) {
    Log.d(TAG, "input file does not exist");
    callback.error("input video does not exist.");
    return;
}

// recording
final File inFile2 = this.resolveLocalFileSystemURI(options.getString("fileUri2"));
if (!inFile2.exists()) {
    Log.d(TAG, "input file2 does not exist");
    callback.error("input video2 does not exist.");
    return;
}

// outro
final File inFile3 = this.resolveLocalFileSystemURI(options.getString("fileUri3"));
if (!inFile3.exists()) {
    Log.d(TAG, "input file3 does not exist");
    callback.error("input video3 does not exist.");
    return;
}

// overlay
final File inFile4 = this.resolveLocalFileSystemURI(options.getString("fileUri4"));
if (!inFile4.exists()) {
    Log.d(TAG, "input file4 does not exist");
    callback.error("input video4 does not exist.");
    return;
}

final String videoSrcPath = inFile.getAbsolutePath();
final String videoSrcPath2 = inFile2.getAbsolutePath();
final String videoSrcPath3 = inFile3.getAbsolutePath();
final String videoSrcPath4 = inFile4.getAbsolutePath();

VideoEditor.java第250行 

FfmpegController ffmpegController = new FfmpegController(appContext, appContext.getCacheDir());
TranscodeCallback tcCallback = new TranscodeCallback();

ArrayList<Clip> listVideos = new ArrayList<Clip>();

Clip clip = new Clip();
clip.path = new File(videoSrcPath).getCanonicalPath();
ffmpegController.getInfo(clip);
clip.duration = 5;
listVideos.add(clip);

Clip clip2 = new Clip();
clip2.path = new File(videoSrcPath2).getCanonicalPath();
ffmpegController.getInfo(clip2);
clip2.duration = 5;
listVideos.add(clip2);

Clip clip3 = new Clip();
clip3.path = new File(videoSrcPath3).getCanonicalPath();
ffmpegController.getInfo(clip3);
clip3.duration = 5;
listVideos.add(clip3);

Clip clipOut = new Clip();
clipOut.path = new File(outputFilePath).getCanonicalPath();

ffmpegController.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false, new ShellUtils.ShellCallback() {
    @Override
    public void shellOut(String shellLine) {
        System.out.println("fc>" + shellLine);
    }
    @Override
    public void processComplete(int exitValue) {
        if (exitValue < 0)
            System.err.println("concat non-zero exit: " + exitValue);
    }
});

FfmpegController.java第664行 

/*
double dValue = mediaIn.duration;
int hours = (int)(dValue/3600f);
dValue -= (hours*3600);

cmd.add("0");
cmd.add(String.format(Locale.US,"%s",hours));
cmd.add(":");

int min = (int)(dValue/60f);
dValue -= (min*60);

cmd.add("0");
cmd.add(String.format(Locale.US,"%s",min));
cmd.add(":");

cmd.add(String.format(Locale.US,"%f",dValue));
*/
cmd.add(Double.toString(mediaIn.duration));
