结合使用mp4parser在Android MP4S [英] Combine Mp4s using mp4parser on Android

问题描述

我只是想知道，如果有人知道如何采取一个MP4的音频文件，并使用 mp4parser Android上覆盖其上的MP4的视频文件。我已经能够添加一个视频与另一个，现在我只需要覆盖原始的MP4，我有过合并的文件。

I was just wondering if anybody knows how to take an mp4 audio file and overlay it onto an mp4 video file using mp4parser on Android. I have been able to append one video with another, now I just need to overlay a raw mp4 that I have over the combined file.

任何帮助将是AP preciated！

Any help would be appreciated!

推荐答案

以下code复用器两个音频语言和视频。它应该很容易将其采纳您的需要：

The following code muxes two audio languages and a video. It should be easy to adopt it to your needs:

public static void main(String[] args) throws IOException {

    String audioDeutsch = MuxMp4SourcesExample.class.getProtectionDomain().getCodeSource().getLocation().getFile() + "/count-deutsch-audio.mp4";
    String audioEnglish = MuxMp4SourcesExample.class.getProtectionDomain().getCodeSource().getLocation().getFile() + "/count-english-audio.mp4";
    String video = MuxMp4SourcesExample.class.getProtectionDomain().getCodeSource().getLocation().getFile() + "/count-video.mp4";


    Movie countVideo = MovieCreator.build(new FileInputStream(video).getChannel());
    Movie countAudioDeutsch = MovieCreator.build(new FileInputStream(audioDeutsch).getChannel());
    Movie countAudioEnglish = MovieCreator.build(new FileInputStream(audioEnglish).getChannel());

    Track audioTrackDeutsch = countAudioDeutsch.getTracks().get(0);
    audioTrackDeutsch.getTrackMetaData().setLanguage("deu");
    Track audioTrackEnglish = countAudioEnglish.getTracks().get(0);
    audioTrackEnglish.getTrackMetaData().setLanguage("eng");

    countVideo.addTrack(audioTrackDeutsch);
    countVideo.addTrack(audioTrackEnglish);

    Container out = new DefaultMp4Builder().build(countVideo);
    FileOutputStream fos = new FileOutputStream(new File("output.mp4"));
    out.writeContainer(fos.getChannel());
    fos.close();

}
