• How to upload dynamically generated video thumbnails as a BLOB into MySQL database in PHP

  26 novembre 2015, par Parthapratim Neog

  Here is the code that has been used to create a thumbnail of a uploaded video. The thumbnail is automatically generated successfully, but now, I want to store that thumbnail as a BLOB in the Database.
  I know how to upload an image as a BLOB using form posts, but there is no form posts involved in this.

  Could someone guide me through this ?

   
  
  
  
  
  
   <form action="index.php" method="POST" enctype="multipart/form-data">
  
    <input type="file" />
  
    <input type="submit" value="Upload" />
  
   </form>
  
   &lt;?php
  
   if(isset($_POST['submit'])){
  
    /*
  
    -i input file name
  
    -an Disabled audio
  
    -ss Get image from x seconds in the video
  
    -s  size of the image
  
    */
  
    //Get one thumbnail from the video
  
    $ffmpeg = "C:\\ffmpeg\\bin\\ffmpeg";
  
    //echo $ffmpeg;
  
    $videoFile = $_FILES["file"]["tmp_name"];
  
    $imageFile = "1.jpg";
  
    $size = "120x90";
  
    $getFromSecond = 5;
  
  
  
    //echo "<pre>"; print_r($_FILES); die;
  
    //echo "video location: ",$videoFile,"<br />";
  
    echo $cmd = "$ffmpeg -i $videoFile -an -ss $getFromSecond -s $size $imageFile";
  
  
  
    echo "<br />";
  
    if(!shell_exec($cmd)){
  
     echo "Thumbnail Created!";
  
    }else{
  
     echo "Error creating Thumbnail";
  
    }
  
  
  
    /*// Get multiple thumbnails from one video
  
    $ffmpeg = "C:\\ffmpeg\\bin\\ffmpeg";
  
    $videoFile = $_FILES["file"]["tmp_name"];
  
    $size = "120x90";
  
    for($num =1; $num&lt;=3; $num++){
  
     $interval = $num * 3;
  
     shell_exec("$ffmpeg -i $videoFile -an -ss $interval -s $size $num.jpg");
  
     echo "Thumbnail Created!- $num.jpg<br />";
  
    }
  
    echo "<br />$num thumbnails Created!";
  
    */
  
   } 
  
   ?>

  Shortcut 8x8/16x16 inverse 2D-DCT

  This commit brought back the shortcut implementation of 8x8/16x16
  inverse 2D-DCT. When the eob <= 10, it skips the inverse transform
  operations on row 4:7/4:15 in the first round. For bus_cif at 1000
  kbps, this provides about 2% speed-up at speed 0.

• DiscordJS Music Bot Connects and Then Immediately Disconnects From Voice Channel

  23 janvier 2020, par კΙбthebraɨɴs

  I see that questions similar to this one have been asked, and after following their solutions I still end up the same as I started. Below I have listed my code, a link to test it with a sample bot I created, and the modules you will need to test it using a self-hosted instance.

  My problem is that upon connecting to the specified voice channel, the bot immediately leaves afterwards without any signs of errors or exceptions. I’m not sure if it is a problem with my code, or with one of the libraries I am using. The only console output I receive is as follows :

  Bot Ready For Use
  
  joined channel
  
  left channel

  Thanks !

  My Code

  var voiceChannel = message.member.voiceChannel;
  
  
  
  if (!message.member.voiceChannel) return message.channel.send(`You do realize you have to be in a voice channel to do that, right ${message.author.username}?`)
  
  
  
  if (!message.member.voiceConnection) voiceChannel.join().then(async connection => {
  
  
  
      let streamURL = args.slice(1).join(" ")
  
      let streamTitle = "";
  
      let streamThumb = "";
  
      let streamAuth = "";
  
      let streamAuthThumb = "";
  
  
  
      if (streamURL.includes("https://www.youtube.com") || streamURL.includes("https://youtu.be/") && !streamURL.includes(' ')) {
  
          let results = await youtube.getVideo(streamURL)
