• ffmpeg can't work via nginx + nginx-rtmp-module

  2 mai 2018, par Ubunkun

  nginx version : nginx/1.12.2
  ffmpeg version 3.4.2

  I’m trying to below.
  -> nginx -> ffmpeg multi encode -> HLS publish

  nginx configration is below (nginx.conf)

  worker_processes  1;
  
  
  
  events {
  
      worker_connections  1024;
  
  }
  
  
  
  http {
  
      include       mime.types;
  
      default_type  application/octet-stream;
  
  
  
      sendfile        on;
  
  
  
      keepalive_timeout  65;
  
  
  
      server {
  
          listen       80;
  
          server_name  localhost;
  
  
  
          location / {
  
              root   html;
  
              index  index.html index.htm index.php;
  
          }
  
  
  
      location ~ \.php$ {
  
              root           html;
  
              fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;
  
              fastcgi_index  index.php;
  
              fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
  
              include        fastcgi_params;
  
          }
  
  
  
          error_page   500 502 503 504  /50x.html;
  
          location = /50x.html {
  
              root   html;
  
          }
  
      }
  
  }
  
  
  
  rtmp {
  
      server {
  
          listen 1935;
  
          application hls {
  
              live on;
  
              exec /usr/local/sbin/ffscript.sh $name;
  
          }
  
  
  
          application hls2 {
  
              live on;
  
              hls on;
  
              hls_path /usr/local/nginx/html;
  
              hls_nested on;
  
              hls_fragment 9s;
  
              hls_variant _low  BANDWIDTH=300000;
  
              hls_variant _mid  BANDWIDTH=700000;
  
              hls_variant _high BANDWIDTH=1200000;
  
          }
  
      }
  
  }

  (/usr/local/sbin/ffscript.sh)

  export LIBVA_DRIVERS_PATH=/opt/intel/mediasdk/lib64
  
  export LIBVA_DRIVER_NAME=iHD
  
  export MFX_HOME=/opt/intel/mediasdk
  
  export PKG_CONFIG_PATH=/opt/intel/opencl:
  
  
  
  /usr/local/bin/ffmpeg -i rtmp://localhost/hls/${1} -vcodec h264_qsv -init_hw
  
  _device qsv:hw -b:v 128K -c:a aac -ar 44100 -ac 2 -r 30 -f flv rtmp://localhost/
  
  hls2/${1}_low -b:v 512k -c:a aac -ar 44100 -ac 2 -r 30 -f flv rtmp://localhost/h
  
  ls2/${1}_mid -b:v 1024k -c:a aac -ar 44100 -ac 2 -r 30 -f flv rtmp://localhost/h
  
  ls2/${1}_high

  But it can’t work. The access.log appears just one line.

  192.168.1.121 [02/May/2018:21:52:39 +0900] PUBLISH "hls" "test2" "" - 580840 753 "" "FMLE/3.0 (compatible; Lavf57.55" (21s)

  There is no "hls2" PUBLISH on access log.

  When I tried to run the ffmpeg command line while nginx is running, it was succeed.

  Why ffmpeg called by nginx doesn’t work ? If you have any solution, let me know.

• FFMPEG RTMP not working in my red5pro module on Ubuntu 14.0.4

  24 janvier 2018, par Atul

  This following command not working in my java module (this takes snap from live stream and save it)
  Runtime.getRuntime().exec("ffmpeg -i \"rtmp ://127.0.0.1:1935/live/mytest live=1 timeout=2\" -f image2 -vframes 1 /snaps/testo.jpg") ;

  If I use same command on Ubuntu 14.0.4 console it works. Same command working in my red5pro module on Window but not on Ubuntu.

  When I use
  String[] execStr = "/usr/local/bin/ffmpeg","-i","rtmp ://127.0.0.1:1935/live/mytest","live=1","timeout=2","-f","image2","-vframes","1","/snaps/tt.jpg" ;
  ProcessBuilder pb = new ProcessBuilder("ffmpeg -i rtmp ://localhost/live/mytest live=1 timeout=2 -f image2 -vframes 1 /snaps/testo.jpg") ;

  It always throw stream not found ( in red5pro console)

• avdevice/decklink : Fix compilation of module on OSX

  avdevice/decklink : Fix compilation of module on OSX
  Clang applies the missing-prototypes warning on C++ files, whereas
  
  gcc only applies it to C.  As a result, the decklink_common.cpp file
  
  fails to build because of missing prototypes in DecklinkDispatch.cpp
  
  (which is #included by decklink_common.cpp).
  We don't want to change the actual Blackmagic SDK sources, so
  
  suppress the warning just for that one #include.
