流媒体中的Android MediaRecorder [英] Android MediaRecorder in streaming

问题描述

是否可以流式传输"MediaRecorder 的结果?

Its possible to "stream" result of MediaRecorder?

我能看到的唯一方法是接收 FileDescriptor 的 mediaRecorder.setOutputFile.所以我可以将结果写入文件或通过套接字发送到接收器.

The unique method i can see is mediaRecorder.setOutputFile that receives a FileDescriptor. So i can write the result to a File or send via socket to receiver.

我尝试了第二种解决方案，但结果视频已损坏，因为在流中不可查找".

I tried the second solution but the result video is corrupted because is not "seekable" in stream.

想法是使用android设备的摄像头将结果发布到Red5.

The idea is to use the camera of android device to publish result to Red5.

推荐答案

是的，这是可能的.这是带有 FileDescriptor 和套接字的示例代码:

Yes it is possible. Here is the sample code with FileDescriptor and socket:

    socket = new Socket("192.168.1.234",8888);
    ParcelFileDescriptor fileDescriptor = ParcelFileDescriptor.fromSocket(socket);

    mRecorder = new MediaRecorder();
    mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mRecorder.setOutputFile(fileDescriptor.getFileDescriptor);
    mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

    try {
        mRecorder.prepare();
    } catch (IOException e) {
        Log.e(LOG_TAG, "prepare() failed");
    }

    mRecorder.start();
