• Nginx with rtmp-module stalls between streams

  14 janvier 2015, par churchmf

  I’m experiencing some troubles using NGINX with rtmp-module as a media server. I wish to present a continuous video as a live stream (with up to 60 second latency). However, due to some hardware constraints, I am unable to stream directly from the device. Instead, I can save out X amount of seconds from the device’s buffer as an MP4. My solution has been to save X seconds of video from the device then stream that X seconds, rise and repeat. This has been working mostly well, except for stalls ( 20 seconds) in the stream between calls.

  I have searched far and wide for a solution to this however most of the people experiencing this problem have the collection of videos before starting the stream and can simply concatenate them.

  My running theory is that when a stream finishes, it does an unpublish event in NGINX followed by a timeout period. This prevents the NGINX server from receiving the next publish until the timeout period has expired. I have tried adjusting nginx.config values related to timeouts, respawns, restarts, and publish, but to no avail.

  Pseudocode :
  while true
   > capture X seconds of video to "output.mp4" (this takes less than 300ms)
   > stream the MP4 with FFMPEG (takes X seconds using -re)

  FFMPEG call :
  ffmpeg -re -i "output.mp4" -vcodec libx264 -preset veryfast -maxrate 2000k -bufsize 4000k -g 60 -acodec libmp3lame -b:a 128k -ac 2 -ar 44100 -f flv rtmp :/MYSERVER/live/output

  I am using JWPlayer client side to watch the video stream, however I experience similar issues using VLC.

  I have been trying to figure this out for a few days and I would appreciate any insight an expert to video streaming and NGINX can give. Thank you !

• nginx rtmp-module can't execute ffmpeg

  22 août 2014, par Nasir

  I am having an issue with nginx-rtmp-module exec ffmpeg command. i have followed the example on
  www.github.com/arut/nginx-rtmp-module

  /home/junaid/bin/ffmpeg -f video4linux2 -i /dev/video1 -c:v libx264 -an -f flv rtmp://127.0.0.1:1935/myapp/mystream

  the command is working fine in terminal

  Config file :

  rtmp {
  
  server {
  
      listen 1935;
  
      ping 30s;
  
      notify_method get;
  
  
  
      application myapp {
  
      live on;
  
      allow play all;

  I have tried :

  • nginx running as root (have permission to execute ffmpeg)
  • using ip instead of localhost
  • using complete path to ffmpeg
  • executing bash file (having ffmpeg and echo commands : echo commands execute just fine) from nginx

  please help me resolve this issue
