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

  2 May 2018, by 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.

• avformat/mov: Enable jpeg streams in HEIF MOVContext

  17 July, by Eric Joyner

  avformat/mov: Enable jpeg streams in HEIF MOVContext
  Nikon HEIFs from a camera or NX studio include a small jpeg thumbnail in addition to
  
  the expected HEVC thumbnails; allowing jpegs allows all thumbnails to
  
  have an associated stream for Nikon HEIF files.
  With this, Nikon HEIFs can finally be decoded without failing and the
  
  thumbnails can be extracted into their own files.
