• nginx rtmp module fails to stream MP4 format

  23 avril 2019, par Keivan

  I have media server running on Nginx rtmp module + ffmpeg
  It is working 100% fine with FLV format but with MP4 it does not create .m3u8 file and stream chunks.
  here is nginx.conf file :

  worker_processes  auto;
  
  
  
  events {
  
      worker_connections  1024;
  
      multi_accept on;
  
  }
  
  
  
  rtmp {
  
    server {
  
      listen 1935;
  
      chunk_size 4000;
  
  
  
      application live {
  
          live on;
  
          record off;
  
  
  
          hls on;
  
      hls_path        /HLS/live;
  
  
  
          hls_keys on;
  
          hls_key_path       /HLS/keys;
  
          hls_key_url        https://fakeurl:8441/keys/;
  
      hls_fragments_per_key   10;
  
  
  
          hls_fragment 3s;
  
          hls_playlist_length 10s;
  
          deny play all;
  
      }
  
    }
  
  }
  
  
  
  http {
  
      include       mime.types;
  
      tcp_nopush on;
  
      directio 512;
  
      default_type  application/octet-stream;
  
      sendfile      off;
  
  
  
      server {
  
          listen       8441 ssl;
  
      server_name  fakeurl;
  
  
  
          ssl_certificate /home/ubuntu/Keys/server.crt;
  
          ssl_certificate_key /home/ubuntu/Keys/server.key;
  
  
  
          location /keys {
  
              root /HLS/;
  
          }
  
  
  
          location / {
  
              root   html;
  
              index  index.html index.htm;
  
          }
  
  
  
          location /live {
  
  
  
              # Disable cache
  
              add_header 'Cache-Control' 'no-cache';
  
  
  
              # CORS setup
  
              add_header 'Access-Control-Allow-Origin' '*' always;
  
              add_header 'Access-Control-Expose-Headers' 'Content-Length';
  
  
  
              # allow CORS preflight requests
  
              if ($request_method = 'OPTIONS') {
  
                  add_header 'Access-Control-Allow-Origin' '*';
  
                  add_header 'Access-Control-Max-Age' 1728000;
  
                  add_header 'Content-Type' 'text/plain charset=UTF-8';
  
                  add_header 'Content-Length' 0;
  
                  return 204;
  
              }
  
  
  
              types {
  
                  application/vnd.apple.mpegurl m3u8;
  
              }
  
  
  
              root /HLS/;
  
          }
  
  
  
  
  
          #error_page  404              /404.html;
  
  
  
          # redirect server error pages to the static page /50x.html
  
          #
  
          error_page   500 502 503 504  /50x.html;
  
          location = /50x.html {
  
              root   html;
  
          }
  
      }
  
  }

  and this is FFmpeg command for creating converting my RTP stream to MP4 and stream it to RTMP server :

  ffmpeg -protocol_whitelist 'file,udp,rtp' -i input.sdp -c:v libx264 -pix_fmt yuv420p -profile:v baseline -level 3.0 -g 30 -r 30 -c:a aac -b:v 400k -preset ultrafast -tune zerolatency -movflags frag_keyframe -f mp4 rtmp://0.0.0.0:1935/live/stream1

  I can confirm ffmpeg works fine and it is stable with the input stream, if I change output format to flv, rtmp server creates stream1.m3u8 file and everything is fine. But with mp4, mov or m4v formats nginx does not create anything.

• PHP : Video file is located in s3, need to find duration a video using getid3 php module

  14 mars 2019, par kaliyappan

      $request = $s3Client->createPresignedRequest($cmd, '+20 minutes');
  
      echo $presignedUrl = (string)$request->getUri();
  
  
  
      echo "\n";
  
      //$mp3File = '/home/kaliyappan/test-HD.mov';
  
      $getId3 = new GetId3();
  
      $audio = $getId3->analyze($presignedUrl);
  
      //echo '<pre>';
  
      print_r($audio);
  
      exit;
  
  </pre>

  I have a video file located in s3, using PHP "phansys/getid3" : "^2.1@dev" module need to calculate duration. Created pre-signed URL try to access that file but it returns "could not open that file".

  [GETID3_VERSION] => 1.9.4-20120530
  
  [error] => Array
  
      (
  
          [0] => Could not open "

  Please suggest any other way to do this, but if I directly give video file path which is in my server that’s work perfectly.

• NodeJS : Set path to FFMPEG binaries for module Fluent-FFMPEG

  2 septembre 2018, par jansmolders86

  I am building a application that uses the module node-fluent-ffmpeg. https://github.com/schaermu/node-fluent-ffmpeg

  And I’m trying to package the ffmpeg binaries along with my application.
  I want to do this so (especially on Windows) the user does not have to install FFMPEG manually.

  Sadly everything I’ve tried results in errors. I’ve tried the following :

    ffmpeg.setFfmpegPath   : Gives an error saying setFfmpegPath is not a method

  and :

    proc.setFfmpegPath    : Gives a createproces error.

  It seems I’m doing something wrong. Could someone point out my mistake.
  Thanks a lot.
