• Stream Live Video and relay audio only to icecast2 server

  28 avril 2019, par BadAddy

  I have a working nginx server which allows me to stream live video from our mobile production system. We also have a radio station on a separate server and would like to stream to both. But I cannot make it work, nor can I get any logs or error information to explain why. I have tried nginx config and FFMPEG to try and resolve this.

  I have tried various attempts using what I think I understand from other pages online :

  exec_push FFREPORT=file=ffreport.log:level=48 ffmpeg -i $basename.flv -vn -acodec mp3 rtmp://source:********!!@xxx.xxx.xxx.180:8000/live;

  Also tried using the simple restream in the nginx conf :

  application restream {
  
                      live on;
  
                      exec_push ffmpeg -i $basename.flv -vn -acodec mp3 rtmp://source:***********@xxx.xxx.xxx.180:8000/live;
  
                      # push server2:1935
  
              }

  I have used the same information on Mixxx Live Broadcast Connection to get the details, thinking I am asking the same thing on the icecast2 server. Just the source is the nginx server.

  This is the full conf on nginx

  rtmp {
  
  
  
      server {
  
              listen 1935;
  
              chunk_size 4000;
  
  
  
              application live {
  
                      live on;
  
                      allow publish 127.0.0.1;
  
                      allow publish all;
  
                      allow play all;
  
                      record all;
  
                      record_path /usr/local/nginx/flv-streams;
  
                      record_unique on;
  
                      exec_record_done ffmpeg -i $basename.flv /usr/local/nginx/html/streams/$basename.mp4;
  
                      hls on;
  
                      hls_nested on;
  
                      hls_path /mnt/hls;
  
                      hls_fragment 1s;
  
                      hls_sync 1ms;
  
                      #exec_push FFREPORT=file=ffreport.log:level=48 ffmpeg -i $basename.flv -vn -acodec mp3 rtmp://source:*************@xxx.xxx.xxx.xxx:8000/live;
  
              }
  
              # Video on Demand
  
              application streams {
  
                      play /usr/local/nginx/html/streams/;
  
              }
  
  
  
              # Restream
  
              application restream {
  
                      live on;
  
                      exec_push ffmpeg -i $basename.flv -vn -acodec mp3 rtmp://source***************@xxx.xxx.xxx:8000/live;
  
                      # push server2:1935
  
              }
  
  
  
      }

  I would like those that can watch any broadcast with video, but if they can only listen, like a radio, I want them to listen via our radio player. They are two different streams, on different servers.

  At the moment I am using software to stream to both and would like to prevent this.

  Not found, by my own wording perhaps, any idea on how to do this.

  UPDATE

  With the help from TBR I have managed to get the stream from the Nginx Server going to a new server hosting icecast2. However, not in the way expected. It does this 32x faster, so not a stream as such.

  ffmpeg -i fcpr-1554651146.flv -vn -c:a mp3 icecast://source:password@10.0.0.0:8000/fcprlive.mp3

  However, I wonder if I have been thinking of this the wrong way. In my liquidsoap file I have this code :

   #!/usr/bin/liquidsoap
  
   # Log dir set("log.file.path","/tmp/basic-radio.log")
  
   # Music
  
   myplaylist = mksafe(playlist("/home/offlineftp/playlist"))
  
  
  
   #Live Source
  
   set("harbor.bind_addr","0.0.0.0")
  
   live = input.http("http://localhost:8000/fcprlive")
  
   radio = fallback(track_sensitive=false, [live,plist])
  
  
  
   # Stream it out
  
   output.icecast(%mp3, host = "localhost", port = 8000,
  
   password = "pass", mount = "/fcpr")

  Should I look at using LiquidSoap to pull the stream from Nginx, when live, and if no signal than go to the fallback ?

• Pre-Transcoding live streams before Re-stream them to wowza Streaming Engine [on hold]

  14 décembre 2017, par Ninja

  i’am using ffmpeg on other device to get live feed from cam and convert them to multi bitrate outputs localy and stream them to a remote wowza to achieve adaptive bitrate content for users with optimized resources i have succeeded to transcode to one specifique bitrate locally using this line

   ffmpeg -re -i cuted.mp4 -c:v libx264 -profile:v baseline -level:v 1.2 -r 12 -g 96 -vb 110000 -s 212x120 -c:a libvo_aacenc -ab 40000 -ar 22050 -ac 1 -f rtsp -muxdelay 0.1 rtsp://*****:*****@***.168.*0.*0:1935/live/myStream

  but i need at least 4 resolutions support i’ve tried to lunched twice at the same time with diffrent resolutions but in wowza engine manager => incoming streams i got one stream input, i appreciate any suggestion
