How can I get audio in my ffmpeg stream to nginx rtmp server ?

26 novembre 2013, par Conor Patrick

I currently have a nginx server setup with the rtmp plugin for video streaming. I'm streaming to it with ffmpeg and then displaying the stream on a web browser with adobe flash player.

I have the video streaming successfully but I have not been able to get audio.

This is the ffmpeg command I use to start the stream

ffmpeg -f video4linux2 -s 320x240 -r 16 -i /dev/video0 -f alsa -i hw:0 -an -f flv rtmp://123.456.789.51:31002/rover/mystream

The stream then goes to nginx which is running on this conf file

worker_processes  1;



error_log  logs/user/error.log debug;



events {

    worker_connections  1024;

}



rtmp {

    server {

        listen 31002;



        application rover {

            live on;

            #meta copy;

            #interleave on;

            allow publish all;

            allow play all;



            hls on;

            #record keyframes;

            #record_path /tmp;

            #record_max_size 128K;

            #record_interval 30s;

            #record_suffix .this.is.flv;



            #on_publish http://localhost:8080/publish;

            #on_play http://localhost:8080/play;

            #on_record_done http://localhost:8080/record_done;

        }

    }

}



http {

    server {

        listen      26360;



        location /stat {

            rtmp_stat all;

            rtmp_stat_stylesheet stat.xsl;

        }



        location /stat.xsl {

            root nginx-rtmp-module-master/;

        }



        location /control {

            rtmp_control all;

        }



        #location /publish {

        #    return 201;

        #}



        #location /play {

        #    return 202;

        #}



        #location /record_done {

        #    return 203;

        #}



        location /rtmp-publisher {

            root /path/to/test;

        }



        location / {

            root nginx-rtmp-module-master/test/www;

        }

    }

}

I then access the stream from a browser using this set up for the adobe flash player and strobe media player.

Could I get some suggestions as to how I couldn't be getting audio ? I'm streaming video from my webcam and specifying audio from my mic.

Is there a media server which just receives any rtsp streams and serves them ?

7 mai 2015, par Given92

I have some rtmp streams served over nginx-rtmp-module and the number of them will be changed dynamically.

But for the limit of client, I have to serve them in rtsp protocol. Obviously, It’s not supported by nginx-rtmp-module. So I plan to run a rtsp server in the same device, and convert the rtmp stream into rtsp stream with ffmpeg, then send the rtsp stream to the rtsp server. So that client could play the stream from the rtsp server.

The trouble is that I could not found a stable server which just receive any rtsp streams and serve them.

There is an example that fits all my need but it’s a little unstable.

I run it in verbose mode and send stream with :

ffmpeg -i rtmp://localhost/<name> -codec copy -ar 44100 -ac 1 -f rtsp rtsp://localhost:5545/<name>

</name></name>

and play the stream with :

gst-launch-0.10 playbin2 uri=rtsp://<server>/<name>

</name></server>

The video does not appear and there are some repeated warnning like this :

WARNING: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstRtpVorbisDepay:rtpvorbisdepay0: Could not decode stream.

Additional debug info:

When I try :

gst-launch-1.0 playbin uri=rtsp://<server>/<name>

</name></server>

it is stuck and no video appear :

When I play with :

The video appears but the quality depress me.

Here is the output :

I’m not sure whether ffmpeg or rtsp-server is the problem, does anyone have some ideas ?

Thanks very much.

How to get rtp(javacv ffmpeg) stream from VLC as client

15 avril 2015, par Sezertt

I am trying to play rtp stream from vlc player which I created using javacv. Here is the code :

        FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber("rtsp://10.6.0.147:554/ufirststream");

        frameGrabber.start();  // First I take another stream 



        FFmpegFrameRecorder frameRecorder = new FFmpegFrameRecorder("rtp://239.31.31.69:4433", frameGrabber.getImageWidth(), frameGrabber.getImageHeight());



        frameRecorder.setFormat("rtp");

        frameRecorder.setPixelFormat(AV_PIX_FMT_YUV420P);

        frameRecorder.setVideoCodec(AV_CODEC_ID_MPEG2VIDEO); &lt;-- AV_CODEC_ID_H264

        frameRecorder.setFrameRate(25);           

        frameRecorder.setVideoBitrate(1024); &lt;--1024*1024*2            

        frameRecorder.start();

        while (true) {

            frameRecorder.record(frameGrabber.grab()); //grab from stream, stream with rtp

        }

If I choose my codec as AV_CODEC_ID_MPEG2VIDEO I can play the stream from VLC using rtp ://239.31.31.69:4433 with open network.

If I increase the quality using setVideoBitrate(1024*1024*2) the stream lags too much and if I decrease the quality is so bad.

I want to use AV_CODEC_ID_H264 as my codec to fasten things with better quality but i can’t play the stream from VLC getting error :

SDP required A description in SDP format is required to receive the RTP stream. Note that rtp :// URIs cannot work with dynamic RTP payload format (96).

I tried to get sdp using wireshark and then I realized rtp stream doesn’t have sdp :) so I tried to create my own sdp like this

c=IN IP4 239.31.31.69

m=video 4433 RTP/AVP 96

a=rtpmap:96 H264/90000

and this

v=0

c=IN IP4 239.31.31.69

a=recvonly

t=0 0

m=video 4433 RTP/AVP 99

a=rtpmap:99 H264/90000

a=fmtp:99 packetization-mode=1;profile-level-id=42c01e;sprop-parameter sets=Z0LAHukBQHsg,aM4G4g==;

but both seems to fail similar to this
