android - 如何使用 exoplayer 流式传输 rtsp url？

Question

我想使用 exoplayer 流式传输 rtsp 视频。我正在使用 ExoMedia library这是一个 Android ExoPlayer 包装器。我在 stackoverflow 上搜索过，但没有找到任何好的答案。经过一些谷歌搜索，我发现 exoplayer 不支持 rtsp 流 issue 55 .有什么方法可以使用 exoplayer 流式传输 rtsp url 吗？ 这是我的代码。

public class MainActivity extends AppCompatActivity implements OnPreparedListener{
    EMVideoView emPlayer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        playVideo();
    }


    private void playVideo() {
        emPlayer = (EMVideoView)findViewById(R.id.video_view);
        emPlayer.setOnPreparedListener(this);

        emPlayer.setVideoURI(Uri.parse("rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov"));
    }

    @Override
    public void onPrepared() {
        emPlayer.start();
        Log.v("TAG","video is playing");
    }
}

这是我的日志

现在 ExoPlayer 已经支持 RTSP - https://github.com/google/ExoPlayer/pull/3854

您还可以按照 rtsp 查看示例应用程序 - https://github.com/google/ExoPlayer/pull/3854#issuecomment-377010803
