• Nginx exec_static reconnect

  12 avril 2016, par Nacsster

  Recently I have installed Nginx with rtmp module and ffmpeg

  I have a few commands like this on my nginx.conf

  exec_static ffmpeg -i http://xxxx.m3u8 -threads 1 -c:v libx264 -profile:v baseline -b:v 370K -s 640x360 -f flv -c:a aac -ac 1 -strict -2 -b:a 56k rtmp://xx.xxx.xx.xx/mobile/nameofstream;

  It transcode the input to low bitrate and all works fine =)

  This is the question :
  Every time I restart my nginx server it executes the commands correctly but (I think) if the stream (m3u8 input) is down, ffmpeg doesn’t wait for a future "input up again", just ignore.
  I try with -re command on ffmpeg but it doesn’t work !

  Any help ? Maybe do I need some bash routine ?

• ffmepg suddently stopped working

  30 octobre 2013, par jdartland

  Hi Im using ffmpeg jwplayer to handle my video uploads. It worked just fine untill I added a video upload to a new model. My video files gets uploaded to the database but i can't play them in my jwplayer. I also noticed that ffmpeg converts files to avi eaven though I've specifyed it in both of my models to convert files into flv.

  Here is my javascrip "error" :

  Error loading player:
  
  No playable sources found.

  My models, tabels and vews shuld work cus I haven't changed anything in my old working post module.

  Here is whats happening in the upload :

   LOCAL_STATIC_LIBRARIES := sinch-android-rtc-3.9.3
  
  
  
   LOCAL_LDLIBS := -llog
