• ffmpeg generate m3u8 from mp4 (Resume option)

  20 août 2014, par diogopms

  I have a mp4 file or other file (non mp4 format) and i need generate ts files and m3u8 playlist.

  I am using this command and works fine :

  ffmpeg -i foo.mp4 -codec copy -vbsf h264_mp4toannexb -map 0 -f segment
  -segment_list out.m3u8 -segment_time 10 out%03d.ts

  Now I need to generate many ts simultaneous so i need a "resume option".

  Please see the example below :

  One thread (first 20 seconds (0-20))

  ffmpeg -i foo.mp4 -codec copy -vbsf h264_mp4toannexb -map 0 -f segment
  -segment_list out.m3u8 -segment_time 10 out%03d.ts

  Seconds thread (20 seconds to 40 seconds)

  ffmpeg -i foo.mp4 ......

  Third thread (40 seconds to 60 seconds)

  ffmpeg -i foo.mp4 ......

  I have lots of core processor to do this jobs.

  In resume i need generate .ts files and m3u8 fastest way possible

  I need help or advises to resolve my problem.

  Prove of concept i build a litle script that use -ss and -t option :

  <?php
  
  
  
   //generate all the commands using -ss and -t <seconds> 
  
   $startTime = new DateTime("00:00:00");
  
   for ($i=1; $i &lt; 20; $i++) {
  
      $data = $startTime->format('H:i:s');
  
      $exec = 'ffmpeg  -i "<file>" -ss '.$data.' -t 10 -c:v copy -bsf h264_mp4toannexb -flags -global_header -map 0 -f segment -segment_time 10 -segment_start_number '.$i.' -segment_list '.sprintf("%04d", $i).'_test.m3u8 -segment_format mpegts '.$i.'stream%05d.ts';
  
      shell_exec($exec);
  
      $startTime->modify('+10 seconds');
  
      echo "\n";
  
  }
  
  
  
  //cycle all m3u8 and creates a master hls playlist
  
  $files = glob('*.{m3u8}', GLOB_BRACE);
  
  sort($files);
  
  $ret = "#EXTM3U
  
  #EXT-X-VERSION:3
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXT-X-ALLOW-CACHE:YES
  
  #EXT-X-TARGETDURATION:11
  
  ";
  
  foreach($files as $file) {
  
      $ret .= shell_exec('sed -n -e 6,7p '. $file);
  
  }
  
  $ret .= "#EXT-X-ENDLIST";
  
  
  
  file_put_contents('final.m3u8', $ret);
  
  
  
  ?>
  
  </file></seconds>

  Thanks

• Trying to compile ffmpeg and mpv in Arch Linux : error "undefined reference to pl_log_create_341" [closed]

  4 février 2024, par Mike Nguyen

  Ever since yesterday, I have been struggling to compile ffmpeg, and to a further extent, mpv, on Arch Linux due to the following error that is probably unique to my install :

  


  /usr/bin/ld: libavfilter/libavfilter.so: undefined reference to pl_log_create_341
collect2: error: ld returned 1 exit status
make: *** [Makefile:133: ffplay_g] Error 1
make: *** Waiting for unfinished jobs....
/usr/bin/ld: libavfilter/libavfilter.so: undefined reference to `pl_log_create_341'
collect2: error: ld returned 1 exit status
make: *** [Makefile:133: ffprobe_g] Error 1
/usr/bin/ld: libavfilter/libavfilter.so: undefined reference to `pl_log_create_341'
collect2: error: ld returned 1 exit status
make: *** [Makefile:133: ffmpeg_g] Error 1


  


  I was trying to install mpd on my system, but pacman forced me to remove a ton of essential packages relating to multimedia, Qt, etc. I have since been able to reinstall most of these packages.

  


  However, my ffmpeg has been corrupted (as well as mpv failing to start) due to another error that apparently no one else has been getting (I have searched Google for this) :

  


  symbol lookup error: /usr/lib/libavfilter.so.9: undefined symbol: pl_tone_map_auto


  


  I have both libavfilter.so.9.12.100 and libavfilter.so.9.13.100 in my /usr/lib directory, and I am forced to run sudo ln -s /usr/lib/libavfilter.so.9.12.100 /usr/lib/libavfilter.so.9 every time I run pacman.

  


  I have spent countless hours browsing the web about what solutions are available, but as I said, I seem to be the only one getting these errors.

  


  Whether it's installing ffmpeg-git via the AUR, or removing and reinstalling mpv, nothing seems to fix the problem. And no one else is having this problem.

  


  I might be forced to do a clean install of Arch Linux, but I don't have the time for it.
