• ffmpeg - continuous file streaming over RTMP

  1er mai 2013, par Sébastien Renauld

  I've been looking around for a simple (or perhaps not-so-simple) walkaround for a problem I am having in my set up for a simple test case : video streaming over red5 media server.

  I have built a small-ish library of FLV files scraped from YouTube and managed to play them in succession with the following perl script :

  use Cwd;
  
  use strict;
  
  use warnings;
  
  use DBI;
  
  use DBD::mysql;
  
  
  
  our $db = DBI->connect();
  
  my $dst = "/home/seb/youtube/";
  
  sub streamFile {
  
      my $r = $db->prepare("SELECT name FROM music_flvs ORDER BY RAND() LIMIT 1");
  
      $r->execute();
  
      my @data = $r->fetchrow_array();
  
      my $filename = $data[0]
  
      my $t = `ffmpeg -re -i '${dst}${filename}' -ab 48k -ac 1 -vcodec libx264 -crf 30 -s "640x480" -acodec libfaac -ar 44100 -threads 4 -f flv 'rtmp://server/oflaDemo/music'`;
  
      return 1;
  
  }
  
  while (&streamFile()) {
  
  }

  This script does its purpose extremely well : it plays files one by one through ffmpeg. However, it does so with a crucial problem : it causes an Unpublish event every time it swaps songs, which causes all the clients to disconnect. I would like to prevent this. The event manifests itself in ActionScript as this :

   16:33:54:209 - Playback - NetStream.Play.UnpublishNotify
  
   16:33:54:209 - Playback - NetStream.Play.PublishNotify

  I have seen the concat demuxer and believe that it might somewhat help me. The question is pretty simple : what is the best way to make ffmpeg stream a playlist to a RTMP server without ever causing an Unpublish event ?

• Tunnel Streaming through server

  28 octobre 2017, par Sarathvichet Heng

  I want to be able to stream a hls IPTV streaming but the origin server has country restriction. I also have a VPS server of that country so I want to stream through that VPS.
  For example : a request to server http://vps.com/tv.php?ch=2 and then stream
  But the source behind it is the origin which is http://origin.com/tv/ch2.m3u8?token...............
  I was able to bypass token and fetch the streaming url using php but don’t know how can I mask http://origin.com/tv/ch2.m3u8...... behind http://vps.com/tv.php..........
  . I don’t want to use FFMPEG because it’ll get
  data and rebroadcast a new stream and consume high vps resource.
  and If I capture packet using Wireshark while playing this http://vps.com/tv.php?ch=2 I’ll see http://origin.com/tv/ch2.m3u8?token......... behind it.
