• I can't use HW encoder of QSV by ffmpeg

  6 novembre 2017, par Ubunkun

  I would like to use to encode by Intel H/W encode QSV.

  Intel(R) Core(TM) i7-5650U CPU @ 2.20GHz

  lspci -nn -s 0:02.0
  00:02.0 VGA compatible controller [0300] : Intel Corporation Broadwell-U Integrated Graphics [8086:1626] (rev 09)

  I could install MediaServerStudioEssentials2017R2 and ffpemg.

  It seems like that the encoding is using by software. It’s slow.
  How can I do by H/W encode ? If you know it, let me know it.

• FFmpeg (Thumbnail from video) works in command line, but not in PHP script

  25 juin 2017, par Jun Kim

  I looked at the similar questions, and the solutions there do not work in my case. Anyone has any idea ? I am trying to capture a thumbnail from a given video file.

  Later, my goal is to capture a thumbnail from live streaming video file.

  Below is my current set up.

  Linux Ubuntu 16.04

  PHP version 7.0

  Nginx Version 1.10.3

  FFmpeg Version FFmpeg 2.8.11

  I installed FFmpeg through below commands in my Ubuntu server.

  apt-get update
  
  apt-get install ffmpeg

  When I type the below command line in the terminal, it does the conversion fine.

  ffmpeg -i /etc/nginx/html/test.mp4 -ss 00:00:01 -vframes 1 -vf scale=240:120 /etc/nginx/html/Share/ffmpeg/thumbnails/test.png;

  In order to use it in php file, I confirmed the location of ffmpeg binaries by I typing in the terminal, which ffmpeg, and it returns /usr/bin/ffmpeg

  I also gave permission to the directory by using chmod 755 command line.

  Here is what I have in my ffmpeg.php file.
  I included the full path to my ffmpeg as you can see.

  <?php
  
  header("Content-Type: text/html;charset=UTF-8");
  
  
  
  $ffmpeg = "/usr/bin/ffmpeg";
  
  $videoFile="/etc/nginx/html/test.mp4";
  
  $thumbnail= "/etc/nginx/html/Share/ffmpeg/thumbnails/thumbnail1.jpg";
  
  
  
  $cmd = "$ffmpeg -i $videoFile -ss 00:00:01 -vframes 1 -vf scale=240:120 $thumbnail 2>&1 &";
  
  
  
  $output = shell_exec($cmd);
  
  echo "<pre>".$output."</pre>";
  
  ?>

  This returns the message like below.

• ffmpeg HLS transcoding and chunks upload to remote server

  I am trying to create a so called origin server for storing the hls chunks and the manifest file on a remote server. The sending machine running ffmpeg is with IP : 192.168.178.50 and the web server which has to store both the HLS chunks and the manifest file is with IP : 192.168.178.100. My ffmpeg transcoding command line is :

  My web server is running apache2 on Ubuntu 16.04 :

  



  $ apache2 -v

Server version: Apache/2.4.18 (Ubuntu)
Server built:   2017-06-26T11:58:04


  



  So according to the access.log file no matter what method I define in the ffmpeg command line it is always trying to upload the chunks using HTTP POST, but the latter is already supported and the directory I am directing the chunks has even 777 rights. Am I missing something here ?
