how to stream rtsp url using exoplayer?

问题

I want to stream rtsp video using exoplayer. I am using ExoMedia library which is an An Android ExoPlayer wrapper. I have search on stackoverflow but I didn't find any good answer. After some google search I found that exoplayer does not support rtsp stream issue 55. Is there any way to stream rtsp url using exoplayer? Here is my code.

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");
    }
}

Here is my log

com.google.android.exoplayer.ExoPlaybackException: com.google.android.exoplayer.upstream.HttpDataSource$HttpDataSourceException: Unable to connect to rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov

Now ExoPlayer has support RTSP - https://github.com/google/ExoPlayer/pull/3854

Also you can follow to see example app with rtsp - https://github.com/google/ExoPlayer/pull/3854#issuecomment-377010803

回答2:

Actually current version of ExoPlayer doesn't support RTSP. But as indicated in the issue issue 55 there's an active pull request #3854 to add this support.

In the meantime, you can clone the original authors exoplayer fork which does support RTSP (branch dev-v2-rtsp):

git clone -b dev-v2-rtsp https://github.com/tresvecesseis/ExoPlayer.git.

I've tested it and it works perfectly. The authors are working actively to fix the issues reported by many users and I hope that RTSP support at some point becomes part of the official exoplayer.

ExoPlayer sort of has support for RTSP in the pull request (you have to grab a local copy, as it's not merged yet.)

There's a small bug (one liner) that I found and fixed in the libraries (if you look at the pull request commentary I noted where it is) but the bigger issue for most users that want to get at something like an Internet Webcam is that the current codebase that is in the pull request does not handle TCP streaming -- only UDP.

That means it won't work if either end is behind a firewall or other NAT instance, which is going to be the case for basically any user on a mobile network and many while on WiFi (especially if the cams are segregated, and they should be as they're notoriously insecure!)

I'm putting some effort into seeing if I can cobble up some patches to their patches, but it may be a while; I've not dug into the ExoPlayer code before, and there's a lot of it to understand....
