Live VLC RTSP on Android

For my application, I need to transfer from the decklink card to an Android application (I have to be a live stream, so either HLS or RTSP seem to be good solutions, since my application is for Android 3+). I recompiled VLC using decklink sdk and I can stream it to another computer over the network (but it only works with 60 seconds 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 works in Android VLC 0.0.11, but only in WiFi, not in 3G. And I can not play it in my application using 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 , for example:

  • 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 can play the stream on the VLC desktop, but not on Android (even in the Android version of VLC or the default for the Google video player: /). If I do not specify a multiplexer, I can also play it in QuickTime (if I specify a multiplex, either ts or ps, I do not have a video. If I try another multiplexer, VLC tells me that I am allowed to use ts or ps in RTP)

If I try to use the Google video player, I get these messages in the locale:

I think the problem is with the “status: RTSP / 1.0 461 Unsupported transport”, but I don’t see what I can change: I already open the ports that I use and receive the video on another computer.

On an Android phone, I can play some rtsp streams that I found on the Internet, for example: rtsp: //184.72.239.149/vod/mp4: BigBuckBunny_115k.mov. Therefore, it should be possible.

If someone can help ...!

Finally, it was a network problem, I connected my devices via MacBook WiFi sharing, and it seems that it blocked the RTSP stream. Now I use a router and it works in RTSP (I still cannot get the HTTP stream in Android VideoView). However, I still have a timeout problem: the RTSP stream stops after 60 seconds because the VideoView does not send keep alive messages. I will try to do it myself ...

I tested my rtsp server with the openRTSP command.

These are UDP ports blocked.

When accessing rtsp without -t:

 -> $ openRTSP <rtsp_url>

I got a magazine telling me:

 // omit lots of lines.. Created receiver for "video/H264" subsession (client ports 63346-63347) Sending request: SETUP rtsp://61.218.52.250:554/live/ch00_0/trackID=0 RTSP/1.0 CSeq: 4 User-Agent: openRTSP (LIVE555 Streaming Media v2013.12.16) Transport: RTP/AVP;unicast;client_port=63346-63347 Received 47 new bytes of response data. Received a complete SETUP response: RTSP/1.0 461 Unsupported Transport CSeq: 4 Failed to setup "video/H264" subsession: 461 Unsupported Transport

So, switching to TCP using:

 -> $ openRTSP -t <rtsp_url>

It begins to receive data successfully.

Link to openRTSP basics.

Now I need to figure out how to automatically switch to TCP in Android.
