• What could be the reason that PHP isn't outputting video ?

  20 septembre 2014, par Rob Avery IV

  I’m currently trying to create a PHP file in which it can output a video that is not under public_html. I have been using the following PHP script to output video :

  <?php
  
  
  
  //PHP script to output videos
  
  
  
  //Full version of file does a lot of database stuff
  
  
  
  //Get $path of file
  
  
  
  header('Content-type: video/mp4');
  
  header('Content-Length: '.filesize($path)); // provide file size
  
  
  
  $contents = file_get_contents($path);
  
  echo $contents;
  
  //I also tried readfile($path) with the same results

  I have a suspicion that it is my server. So, I tried to view the same video file directly (www.site.com/video.mp4). Doing it directly worked fine.

  Originally, this worked fine. It wasn’t until just recently that it doesn’t work. I’m not sure if it’s something I installed on my server. I remember doing a few changes to the php.ini and maybe .htaccess (or some other hidden with settings inside them) which makes me think it has something to do with that. Is there something within php.ini and/or .htaccess (or any other hidden settings file similar to php.ini and .htaccess) that I would need to change ?

  Right now, I just testing my site on desktop browsers. I’ve tested this on both Chrome and Firefox and they give me the same results. I’ve tried using ffmpeg to convert my videos to many different video formats, but it comes out with the same results (can play directly, can’t play through php script).

  When I open the php file, the console has no errors.

  What could be a reason that my PHP script is not outputting the video content ?

• FFMPEG PUSH to NGINX RTMP server does not work on interlaced content

  1er septembre 2022, par Sambir

  when i add -top 1 -flags +ildct+ilme and push it to the NGINX RTMP server it is unable to "decode" and broadcast the stream. Am i missing something or is NGINX unable to process interlaced content ? FFMPEG works fine with both commands. I also saved the output to a file to check if there is any issues with the output but it looks fine.

  


  My command which doesnt work on the NGINX RTMP server :

  


  ffmpeg -timeout 10000000 -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2 -hwaccel_device 2 -hwaccel cuvid -vcodec h264_cuvid -vcodec h264_cuvid -i 'http://URL' -map 0:1 -map 0:2 -acodec libfdk_aac -b:a 96k -c:v h264_nvenc -gpu 2 -preset llhq -vprofile high -level 4.1 -top 1 -flags +ildct+ilme -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range tv -rc:v vbr -qmin:v 18 -qmax:v 42 -b:v 6M -maxrate 6M -bufsize 12M -threads 0 -r 25 -g 100 -refs 2 -bf 3 -f flv 'rtmp://OUTPUT'


  


  This code works fine :

  


  ffmpeg -timeout 10000000 -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2 -hwaccel_device 2 -hwaccel cuvid -vcodec h264_cuvid -vcodec h264_cuvid -i 'http://URL' -map 0:1 -map 0:2 -acodec libfdk_aac -b:a 96k -c:v h264_nvenc -gpu 2 -preset llhq -vprofile high -level 4.1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range tv -rc:v vbr -qmin:v 18 -qmax:v 42 -b:v 6M -maxrate 6M -bufsize 12M -threads 0 -r 25 -g 100 -refs 2 -bf 3 -f flv 'rtmp://OUTPUT'


  


  The rtmp server then processes the stream and broadcasts it without any problems

  


• FFmpeg package for php

  4 septembre 2013, par Ali faizan

  Does simple ffmpeg package also work fine when we execute its command from PHP via exec ? Or we have some different ffmpeg package for that purpose ?
  Please help me solving it.
