VLC RTSP transmisja na żywo do Androida

Question

Do mojej aplikacji muszę przesyłać strumieniowo z karty decklink do aplikacji na Androida (muszę być transmisją na żywo, więc albo HLS, albo RTSP wydaje się być dobrym rozwiązaniem, ponieważ moja aplikacja jest przeznaczona dla Androida 3+). Przekompilowałem VLC z decklejem SDK i mogę transmitować na żywo do innego komputera przez sieć (ale działa tylko 60 sekund z RTSP).

Oto, co starałem: Stream

• HTTP:

  ./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}' 
  

To działa w Android VLC 0.0.11, ale tylko w WiFi, a nie w 3G. I nie mogę odtwarzać tego w mojej aplikacji z VideoView. Oto kod użyłem i odpowiednie komunikaty o błędach:

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(); 

komunikaty o błędach:

• RTSP:

użyłem opcji kodowania zalecanych przez Google na this page, np .:

Koder-dekoder 10
• wideo: H264
• kodek audio: AAC
• szybkość transmisji wideo: 56
• przepływność audio: 24
• kanałów audio: 1

• rozmiar 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}' 
  

Jestem w stanie odtwarzać strumień na pulpicie VLC, ale nie na Androidzie (nawet w wersji Android VLC lub domyślnej wersji Goo gle odtwarzacz wideo: /). Jeśli nie określiłem muxer, mogę również odtwarzać go w QuickTime (jeśli podam muxer, ts lub ps, nie mam wideo.) Jeśli spróbuję innego muxera, VLC mówi mi, że mogę używać tylko TS lub PS w RTP)

Gdy próbuję z odtwarzacza wideo Google, mam te wiadomości w Locat:

Myślę, że problem jest wskazał na „status: RTSP/1,0 461 nieobsługiwanych transport ", ale nie widzę, co mogę zmienić: już otwierać porty, których używam, i odbieram wideo na innym komputerze.

Na telefonie z Androidem mogę odtwarzać niektóre strumienie rtsp, które znalazłem w Internecie, na przykład: rtsp: //184.72.239.149/vod/mp4: BigBuckBunny_115k.mov. Tak powinno być możliwe.

Jeśli ktokolwiek może pomóc ...!

Answer 1

W końcu to był problem z siecią, podłączałem moje urządzenia przez udostępnianie WiFi w MacBooku i wygląda na to, że zablokował strumień RTSP. Teraz używam routera i działa on w RTSP (nadal nie mogę odbierać strumienia HTTP w Android VideoView). Mimo to, nadal mam problem z limitem czasu: Strumień RTSP zatrzymuje się po 60 sekundach, ponieważ VideoView nie wysyła wiadomości podtrzymujących. Spróbuję zrobić to sam ...

Answer 2

Przetestowałem mój serwer rtsp za pomocą polecenia openRTSP.

To porty UDP zostały zablokowane.

Jeżeli dostępu RTSP bez -t:

-> $ openRTSP <rtsp_url> 

Mam dziennik mówiąc mi:

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

Failed to setup "video/H264" subsession: 461 Unsupported Transport 

więc zmiana na TCP z:

-> $ openRTSP -t <rtsp_url> 

rozpocząć odbieranie danych z powodzeniem.

Ref to openRTSP basics.

Teraz muszę dowiedzieć się, w jaki sposób automatyczny przełącznik TCP w Androidzie.

Answer 3

spróbuj VLC:

vlc some_file.mp4 -I http --sout „#transcode {soverlay AB = 128, próbkowania = 44100, kanały = 2, acodec = mp4a, vcodec = h264, szerokość = 480, wysokość = 270, vfilter = "płótno {szerokość = 480, wysokość = 270, aspekt = 16: 9}", fps = 25, vb = 800, venc = x264 {poziom = 12, no-cabac, subme = 20, wątki = 4, bframes = 0, min-keyint = 1, keyint = 50}}: gather: rtp {mp4a-latm, sdp = rtsp: //0.0.0.0: 5554/stream.sdp} "

a kod android:

@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(); 
     }

Zastosowanie MediaPlayer obsługuje zarówno protokoły sieciowe HTTP, jak i RTSP. http://developer.android.com/guide/topics/media/mediaplayer.html#mediaplayer http://developer.android.com/guide/appendix/media-formats.html#recommendations
