• Recursively convert media directory from HEVC to h.264 with ffmpeg

  8 avril 2016, par chuckcastle

  I have media server with two directories : Movies and TV Shows. Within each of those directories, each entry exists in a sub-directory which contains the video file and subtitle files.

  I’ve scoured the web and have found an excellent perl script from Michelle Sullivan, posted here :

      #!/usr/bin/perl
  
  
  
  use strict;
  
  use warnings;
  
  
  
  open DIR, "ls -1 |";
  
  while (<dir>)
  
  {
  
          chomp;
  
          next if ( -d "$_"); # skip directories
  
          next unless ( -r "$_"); # if it's not readable skip it!
  
          my $file = $_;
  
          open PROBE, "ffprobe -show_streams -of csv '$file' 2>/dev/null|" or die ("Unable to launch ffmpeg for $file! ($!)");
  
          my ($v, $a, $s, @c) = (0,0,0);
  
          while (<probe>)
  
          {
  
                  my @streaminfo = split(/,/, $_);
  
                  push(@c, $streaminfo[2]) if ($streaminfo[5] eq "video");
  
                  $a++ if ($streaminfo[5] eq "audio");
  
                  $s++ if ($streaminfo[5] eq "subtitle");
  
          }
  
          close PROBE;
  
          $v = scalar @c;
  
          if (scalar @c eq 1 and $c[0] eq "ansi")
  
          {
  
                  warn("Text file detected, skipping...\n");
  
                  next;
  
          }
  
          warn("$file: Video Streams: $v, Audio Streams: $a, Subtitle Streams: $s, Video Codec(s): " . join (", ", @c) . "\n");
  
          if (scalar @c > 1)
  
          {
  
                  warn("$file has more than one video stream, bailing!\n");
  
                  next;
  
          }
  
          if ($c[0] eq "hevc")
  
          {
  
                  warn("HEVC detected for $file ...converting to AVC...\n");
  
                  system("mkdir -p h265");
  
                  my @params = ("-hide_banner", "-threads 2");
  
                  push(@params, "-map 0") if ($a > 1 or $s > 1 or $v > 1);
  
                  push(@params, "-c:a copy") if ($a);
  
                  push(@params, "-c:s copy") if ($s);
  
                  push(@params, "-c:v libx264 -pix_fmt yuv420p") if ($v);
  
                  if (system("mv '$file' 'h265/$file'"))
  
                  {
  
                          warn("Error moving $file -> h265/$file\n");
  
                          next;
  
                  }
  
                  if (system("ffmpeg -xerror -i 'h265/$file' " . join(" ", @params) . " '$file' 2>/dev/null"))
  
                  {
  
                          warn("FFMPEG ERROR.  Cannot convert $file restoring original...\n");
  
                          system("mv 'h265/$file' '$file'");
  
                          next;
  
                  }
  
          } else {
  
                  warn("$file doesn't appear to need converting... Skipping...\n");
  
          }
  
  }
  
  close DIR;
  
  </probe></dir>

  The script performs perfectly - as long as it is run from within the directory containing the media.

  My question : Can this script be modified to run recursively from the root directory ? How ?

  Thanks in advance.

• why node-media-server not creating sub folders in server while implementing Live video with RTMP ?

  10 mars 2020, par Kadam Saikumar

  I tried this configuration in local it got works and it creates **./media/live/STREAM KEY** folder and storing video data (MP4 file).
  
      If i push the same code in server it doesnot create sub folders **live/STREAMKEY** and i am using node version 8 and linux server and ffmpeg 4.
  
  
  
  
  
  const nodeMediaServerConfig = {
  
        // logType: 3,
  
        rtmp: {
  
          port: 1935,
  
          chunk_size: 60000,
  
          gop_cache: true,
  
          ping: 60,
  
          ping_timeout: 30
  
        },
  
        http: {
  
          port: 8000,
  
          mediaroot: './media',
  
          allow_origin: '*'
  
        },
  
        trans: {
  
          ffmpeg: '/usr/bin/ffmpeg',
  
          tasks: [
  
            {
  
              app: 'live',
  
              ac: 'aac',
  
              mp4: true,
  
              mp4Flags: '[movflags=faststart]'
  
            }
  
          ]
  
        }
  
      };
  
  
  
      var nms = new NodeMediaServer(nodeMediaServerConfig);
  
      nms.run();

  If i create manually folders will it be useful in server ?

• Vitamio Media Player License Requirements

  27 mai 2015, par Amanda Fernandez

  I have successfully integrated vitamio project in my app and it works perfectly. But I’m not clear about its licence. I found the project in github. It uses ffmpeg library and some of the files have apache license. So can I use, vitamio for enterprise app without the license ? Or license is mandatory. ?
