如何在Android上从h264编码的帧创建mp4文件？

Question

I have some h264 frames already encoded with android encoder. Now i want to create and write them one by one to the mp4 file. Please advise how to do this on android in Java. I don't want to use OpenCV or native code.

mp4-parser can't do this as i understand

navite MPEG4Writer is too complicated to use

Wondering why such a common and very useful thing as mp4 writer NOT FROM CAMERA is not implemented in android

Answer 1

You may use my mp4parser project. You can mux H264 and AAC in pure Java with it:

    H264TrackImpl h264Track = new H264TrackImpl(new FileInputStream("raw.h264").getChannel());
    Movie m = new Movie();
    m.addTrack(h264Track);

    IsoFile out = new DefaultMp4Builder().build(m);
    FileOutputStream fos = new FileOutputStream(new File("h264_output.mp4"));
    out.getBox(fos.getChannel());
    fos.close();
