  • ffmpeg HLS transcoding and chunks upload to remote server

    25 mai 2020, par Georgе Stoyanov

    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 :

    



    $ ffmpeg -i 01_llama_drama_1080p.mp4 -profile:v high -level 5.2 -s 1920x1080 -strict -2 -start_number 0 -hls_time 6 -hls_list_size 0 -f hls http://192.168.178.100/hls/test.m3u8

    But no matter what method I am using I got in the access log of my apache web server the following errors :

    



    $ tail -f /var/log/apache2/access.log

    These are the supported methods on my web server :

    



    $ nmap -Pn -p 80 --script http-methods 192.168.178.100

    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 ?

    


  • 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 failed to call avcodec_send_packet

    It basically leaves everything by its defaults and try to read packets and decode frames from them. The avcodec_send_packet always returned a negative value at the first or second round of calling in the while loop.

    So I guess there must be something wrong around avcodec_send_packet call but could not figured out what is missing. Any ideas about the causes ? Much appreciate your help !
