推荐答案

由于您没有提到格式，因此很难给出建议，但是对于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.

Since you do not mention format it is hard to give advice, but for mp4 this seems to be a good alternative. Even includes example of merging files.

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();
