java - 如何将多个 MP4 视频文件合并为一个文件

Question

我需要使用 java 将多个 MP4 视频文件合并为一个文件。谁能告诉我如何合并视频。我们将不胜感激您的帮助。

Answer 1

由于您没有提及格式，因此很难提供建议，但对于 mp4 来说，这似乎是一个不错的选择。甚至包括合并文件的示例。

代码取自链接:

MovieCreator mc = new MovieCreator();
Movie video = mc.build(Channels.newChannel(AppendExample.class.getResourceAsStream("/count-video.mp4")));
Movie audio = mc.build(Channels.newChannel(AppendExample.class.getResourceAsStream("/count-english-audio.mp4")));

List videoTracks = video.getTracks();
video.setTracks(new LinkedList());

List audioTracks = audio.getTracks();

for(Track videoTrack:videoTracks){
    video.addTrack(new AppendTrack(videoTrack, videoTrack));
}

for(Track audioTrack:audioTracks){
    video.addTrack(new AppendTrack(audioTrack, audioTrack));
}

IsoFile out = new DefaultMp4Builder().build(video);
FileOutputStream fos = new FileOutputStream(new File(String.format("output.mp4")));
out.getBox(fos.getChannel());
fos.close();
