VLC如何将RTSP实时流传输到Android设备？

Question

VLC如何将RTSP实时流传输到Android设备？

11

我需要从Decklink卡流式传输到Android应用程序（必须是实时流，因此HLS或RTSP似乎是很好的解决方案，因为我的应用程序面向Android 3+）。我使用Decklink SDK重新编译了VLC，并能够通过网络将实时流式传输到另一台PC（但RTSP仅适用于60秒）。

这是我尝试过的：

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}'

在Android VLC 0.0.11中它可以工作，但只能在WiFi下使用，不能在3G下使用。而且我无法在我的应用程序中使用VideoView播放它。以下是我使用的代码和相应的错误消息：

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();

错误信息：

RTSP：

我使用了Google在这个页面上推荐的编码选项，例如：

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}'

我能在VLC桌面版本中播放流，但在Android设备上无法播放（包括Android版VLC或默认的Google视频播放器）。如果我不指定复用器，我也可以在QuickTime中播放它（如果我指定复用器，无论是ts还是ps，都没有视频。如果我尝试使用其他复用器，VLC会告诉我只允许在RTP中使用ts或ps）。

如果我尝试使用Google视频播放器，则会在本地收到以下消息：

我猜问题出在"status: RTSP/1.0 461 Unsupported transport"上，但是我不知道我能改变什么：我已经打开使用的端口，并且在另一台电脑上接收到了视频。

在Android手机上，我可以播放我在网上找到的一些rtsp流，例如这个：rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov。所以应该是可能的。

如果有人能帮忙...！

我还想开发一个应用程序，可以显示IP摄像机的实时流。我有经过身份验证的RSTP URL，但Android的VideoView不支持它。我还想记录RSTP...你能指导我如何实现这样的功能吗？ - Nirav Bhandari

我已经使用openRTSP命令测试了我的rtsp服务器。

UDP端口被阻止了。

如果不使用-t访问rtsp：

-> $ openRTSP <rtsp_url>

我收到了一条日志，内容是：

// omit lots of lines..

所以改用TCP：

它成功开始接收数据。

参考openRTSP基础知识。

现在我得弄清楚如何在Android上自动切换到TCP。

抱歉，我已经多年没有接触那个项目了。上次我记得，就像@tim-autin提到的那样，呼叫会在短时间内停止。祝你好运。 - Robert

使用MediaPlayer，它支持HTTP和RTSP网络协议。 http://developer.android.com/guide/topics/media/mediaplayer.html#mediaplayer http://developer.android.com/guide/appendix/media-formats.html#recommendations

请尝试使用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}"

还有安卓代码：

@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();
        }

最终问题是网络问题，我通过MacBook WiFi共享连接设备，似乎阻止了RTSP流。现在我使用路由器，RTSP可以正常工作（但我仍然无法在Android VideoView中接收HTTP流）。尽管如此，我仍然有超时问题：RTSP流在60秒后停止，因为VideoView没有发送保持活动消息。我将尝试自己解决这个问题...
