VLC RTSP live stream to Android

For my app I have to stream from a decklink card to an Android app (I must be a live stream, so either HLS or RTSP seems to be good solutions, since my app targets Android 3+). I recompiled VLC with the decklink sdk, and I am able to live stream to another pc over the network (but it works only 60sec with RTSP).

Here is what I tried :

  • HTTP Stream :

    ./vlc -vvv decklink:// --sout
'#transcode{vcodec=mp4v,acodec=mpga,vb=56,ab=24,channels=1}
:standard{access=http{use-key-frames},mux=ts,dst=:3001/stream.mpeg}'

It is working in Android VLC 0.0.11, but only in WiFi, not in 3G. And I am not able to play it in my app with a VideoView. Here is the code I used and the corresponding error messages :

String url = "http://134.246.63.169:5554/stream.mpeg";

VideoView videoView = (VideoView) this.findViewById(R.id.videoView);
videoView.setVideoURI(Uri.parse(url));        
videoView.setMediaController(new MediaController(this));
videoView.requestFocus();  
videoView.start();

Error messages :

  • RTSP :

I used the encoding options recommended by Google on this page, eg :

  • video codec : h264
  • audio codec : AAC
  • video bitrate : 56
  • audio bitrate : 24
  • audio channels : 1

  • size : 176x144

    ./vlc -vvv decklink:// --sout-ffmpeg-strict=-2 --sout
'#transcode{width=176,height=144,vcodec=h264,acodec=mp4a,vb=56,ab=24,channels=1}
:rtp{dst=134.246.63.169,port-video=5554,port-audio=5556,sdp=rtsp://134.246.63.169:5554/stream.sdp}'

I am able to play the stream in VLC desktop, but not in Android (even in the Android VLC version or the default Google video player:/ ). If I don't specify a muxer, I can also play it it QuickTime (if I specify the muxer, either ts or ps, I have no video. If I try another muxer, VLC tells me that I am only allowed to use ts or ps in RTP)

If I try with the Google video player, I get these messages in the locat :

I guess the problem is pointed with the "status: RTSP/1.0 461 Unsupported transport", but I don't see what can I change : I already open the ports I use, and I do receive the video on another computer.

On the Android phone, I can play some rtsp streams I found on the web, for exemple this one : rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov . So it should be possible.

If anyone can help... !

I've tested my rtsp server with openRTSP command.

It's the UDP ports been blocked.

If accessing rtsp without -t:

-> $ openRTSP <rtsp_url>

I got log telling me: 

// omit lots of lines..
Created receiver for "video/H264" subsession (client ports 63346-63347)

So changing to TCP with:

it start receiving data successfully.

Ref to openRTSP basics.

Now I've got to figure out how to auto switch to TCP in Android.

please try the VLC:

vlc some_file.mp4 -I http --sout "#transcode{soverlay,ab=128,samplerate=44100,channels=2,acodec=mp4a,vcodec=h264,width=480,height=270,vfilter="canvas{width=480,height=270,aspect=16:9}",fps=25,vb=800,venc=x264{level=12,no-cabac,subme=20,threads=4,bframes=0,min-keyint=1,keyint=50}}:gather:rtp{mp4a-latm,sdp=rtsp://0.0.0.0:5554/stream.sdp}"

and the android code:

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

        final VideoView vidView = (VideoView)findViewById(R.id.myVideo);

        MediaController vidControl = new MediaController(this);
        vidControl.setAnchorView(vidView);
        vidView.setMediaController(vidControl);

        vidView.setVideoPath("rtsp://137.110.92.231:5554/stream.sdp");

        vidView.start();
        }

Finally it was a network problem, I was connecting my devices through a MacBook WiFi sharing, and it seems that it blocked the RTSP stream. Now I am using a router and it works in RTSP (I'm still not able to receive a HTTP stream in the Android VideoView). Nevertheless, I still have a timeout issue : the RTSP stream stops after 60 sec, because the VideoView doesn't send keep alive messages. I will try to do it myself...
