  • php video upload and ffmpeg won't create a thumbnail

    18 mai 2020, par Azzo

    I am trying to make a video upload feature for my project. But I have a problem with ffmpeg section. ffmpeg is already installed on my server. But i can not get any thumbnail. I have try to create thumbnail using the following code :

    



    $videoa = exec("/usr/bin/ffmpeg  -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4 2>&1");
$videob = exec("/usr/bin/ffmpeg  -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");


    



    But i ge this when use var_dump(); for var_dump($videoa); and var_dump($videob);

    



    


    string(74) "https://mywebsite.com/uploads/video/ey1kXNew_video.flv :
 Input/output error" string(0) ""

    


    



    Also if i use the shell_exec like this :

    



    $videoa = shell_exec("/usr/bin/ffmpeg  -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4");
$videob = shell_exec("/usr/bin/ffmpeg  -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");


    



    and the var_dumps() giving me NULL NULL.

    



    Please help me where am I wrong.

    



    And here is my full video upload code :

    



    $valid_formats = array("mp4","MP4","flv");
            if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST") {
               $name = $_FILES['uploading']['name'];
               $size = $_FILES['uploading']['size'];
               if(strlen($name)) {
                   $ext = strtolower(pathinfo($name, PATHINFO_EXTENSION)); 
                   $name = alphaID(microtime(true) * 10000).'_video';
                   if(in_array($ext,$valid_formats)) {
                   if($size<(50024*50024)) {
                      $GetVideoName = $name;
                      $video_ext=$ext;
                       $tmp = $_FILES['uploading']['tmp_name'];
                       if(move_uploaded_file($tmp, $videoPath.$GetVideoName.'.'.$video_ext)) {
                           $videoUrlp = $base_url.'uploads/video/'.$GetVideoName;
                           $videoa = exec("/usr/bin/ffmpeg  -i $videoUrlp.flv -f flv -s 650x390 $videoUrlp.mp4 2>&1");
                           $videob = exec("/usr/bin/ffmpeg  -i $videoUrlp.mp4 -vcodec png -ss 00:00:5 -s 650x390 -vframes 1 -an -f rawvideo $videoUrlp.png");
                           echo var_dump($videoa);
                           echo var_dump($videob);

                        } else {
                            echo "Fail upload folder with read access.";
                        }
                     } else
                        echo "Image file size max 1 MB";                    
                     } else
                        echo "invalidvieo"; 
                 } else
                    echo "Please select image..!";
                 exit;
              }


    



    I have tested also like this way :

    



    echo exec("/usr/bin/ffmpeg -i $videoUrlp.flv -ar 22050 -ab 32 -f flv -s 780x400 $videoUrlp.$video_ext");
echo exec("/usr/bin/ffmpeg -i $videoUrlp.$video_ext -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $videoUrlp.png 2>&1");


    



    and I see the following echo

    



    video:71kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.000000%

    



    and another try then I get this note : https://mywebsite.com/uploads/video/1547892356_video.flv : Connection refused

    



    echo exec("/usr/bin/ffmpeg -i $videoUrlp.flv -ar 22050 -ab 32 -f flv -s 780x400 $videoUrlp.$video_ext");
echo exec("/usr/bin/ffmpeg -i $videoUrlp.$video_ext -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $videoUrlp.png 2>&1");


    



    Here is last shell_exec Output :

    



     $local = 'https://website.com/uploads/video/'.$GetVideoName.'.'.$video_ext;
 $localTumb = 'https://website.com/uploads/video/'.$GetVideoName.'.png';
 echo shell_exec("/usr/bin/ffmpeg -i $local -deinterlace -an -ss 1 -t 00:00:05 -r 1 -y -vcodec mjpeg -f mjpeg $localTumb 2>&1");

  • ffmpeg, v4l, snd_aloop ... sound asyncron (alsa buffer xrun)

    28 janvier 2019, par Tobias

    I’m trying to create a stream that automatically reloads random inputs. I would like to extend this to a database later.

    Each time ffmpeg finishes and starts again, so the input changes, the connection to the rtmp is interrupted briefly causing the whole connection breaks down. I then tried to separate audio and video, to send them to virtual devices and read from there again. Split the stream on virtual devices, reassemble them directly and send them to rtmp. If the input is then exchanged, the sending to the devices interrupts what does not bother the second ffmpeg. As soon as I stop sending to the devices the fps go very slowly (10 - 20 sec) from 25 to 0. Only then does the transmitter ffmpeg break the connection to the rtmp. The script which exchanges the inputs needs only one second. A practical test showed that everything works as desired.

    I can quite comfortably change the input while the second ffmpeg maintains the stream ...

    The joy did not last long. The sound is good 1 sec delayed. But sporadically. Sometimes everything works great. Sometimes the sound is offset.

    I wrote several scripts for this.

    Background :

    1. File is selected by random
    2. Media file is split and written to / dev / video0 (v4l loopback) and alsa default (snd_aloop loopback)
    3. Put the splits together again and stream them to a rtmp server

    Code that selects the input and sends to / dev / video0 and alsa default

    #!/bin/bash
    

    
cat /dev/null > log
    

    
while true;
    
do
    

    
  WATERMARK="watermark.png";
    
  dir='/homeXXXXXXXXXX/mix'
    
  file=`/bin/ls -1 "$dir" | sort --random-sort | head -1`
    
  DATEI=`readlink --canonicalize "$dir/$file"` # Converts to full path
    

    
if [ -z $DATEI ]
    
then
    
  echo "Keine Datei gefunden" >> log;
    
else
    
  START=$(date +%s);
    
  echo "Sende $DATEI" >> log;
    
  ffmpeg -re -y -i "$DATEI" -c:v libx264 -vf "fps=25,scale=640:480,setdar=4:3" -async 1 -pix_fmt yuv420p -preset ultrafast -map 0:0 -f v4l2 -vcodec rawvideo /dev/video0 -f alsa default
    
fi
    

    
DOKILL=`cat kill`;
    
if [ "$DOKILL" = "1"]
    
then
    
  break;
    
fi
    

    
done

    And then when that comes, dives in the first window, so in the ffmpeg sends the input :

    Does anyone have any advice and can help me ?

  • Today we celebrate Data Privacy Day 2019

    28 janvier 2019, par Jake Thornton — Privacy

    Today we celebrate Data Privacy Day 2019 !!!

    What is Data Privacy Day ?

    Wikipedia tells us that : The purpose of Data Privacy Day is to raise awareness and promote privacy and data protection best practices.

    Our personal data is our online identity. When you think what personal data means – our phone records, credit card transactions, GPS position, IP addresses, browsing history and so much more. All so valuable and personal to us as human beings.

    That’s why we cannot take our personal data online for granted. We have a right to know which websites collect our data and how it’s then used, something that’s often not visible or easily recognisable when browsing.

    What Data Privacy Day means to Matomo

    Every year the team at Matomo uses this day as a chance to reflect on how far the Matomo (formerly Piwik) project has come. But then also reflect how far we still have to go in spreading the message that our data and personal information online matters.

    2018 saw the introduction of the EU General Data Protection Regulation (GDPR) to protect people’s data online. As a team, Matomo was at the forefront of this development in the analytics space and have since built a GDPR Manager to ensure our users can be fully compliant with the GDPR.

    With every new release of Matomo, we are ensuring that security continues to be at the highest standard and we will continue to be committed to our bug bounty program. Our most recent release of Matomo 3.8.0 alone added a Two Factor Authentication (2FA) feature and a password brute force prevention.

    What next for Matomo and data privacy ?

    As always, security is a top priority for every new release of Matomo and continues to only get better and better. We have a duty to spread our message further that the protection of personal data matters and today is a vital reminder of that. We are, and forever will be, the #1 open-source (and free to use) web analytics platform in the world that fully respects user privacy and gives our users 100% data ownership.

    In 2018 we changed our name, we updated our logo and website, and advanced our platform to compete with the most powerful web analytics tools in the world, all so we can spread our message further and continue our mission.

    Come with us on this exciting journey. Now is the time to take back control of your data and let’s continue creating a safer web for everyone.

    Please help us spread this message.
