How to Show result after uploaded file in PHP
23 avril 2022, par i0x4rI have a script that uploads the video to a server, everything is correct but there is a problem, after the upload of the video to the server is completed
it shows all the uploaded files in the (uploads) folder as array !


I only want the result of the file I just uploaded, and it doesn't show me the previous files !
I need ffmpeg to improve video quality


index.php

upload.php


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);
 $locationStr = str_replace(" ","\ ",$location);
 $cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
 echo shell_exec($cmd);
}

if(isset($_POST["name"]))
{
 $filename = $folder_name.$_POST["name"];
 $imagename = $thumb_name.$_POST["name"].$imageext;
 unlink($filename);
 unlink($imagename);
}

$result = array();

$files = scandir('upload');

$output = '<div class="row">';

if(false !== $files)
{
 foreach($files as $file)
 {
 if('.' != $file && '..' != $file)
 {
 $output .= '
 <a href="http://stackoverflow.com/view.php?file=&#x27;.$file.&#x27;" target="_blank"> <img src="http://stackoverflow.com/feeds/tag/thumb/&#x27;.$file.&#x27;.png" class="img-thumbnail" width='246' height='138' /></a>
 <button type="button" class="btn btn-link remove_image">Remove</button>
 ';
 }
 }
}
$output .= '</div>';
echo $output;

?>


EDIT :
I put the example on an Array, I don't want it, I just want it to show the downloaded video I just uploaded as a result.


EDIT 2 :
There are some who say type $location and it displays the downloaded file, but this does not work !!!
I just tried more than once and with several uses, there is no display where the text is empty


This is an example of that


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);
 $locationStr = str_replace(" ","\ ",$location);
 $cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
 echo shell_exec($cmd);
}

if(isset($_POST["name"]))
{
 $filename = $folder_name.$_POST["name"];
 $imagename = $thumb_name.$_POST["name"].$imageext;
 unlink($filename);
 unlink($imagename);
}


$output .= 'Successfly file is "'.$location.'"';
echo $output;

?>


Result : Successfly file is ""
no name file :(


EDIT 3 :


this code upload.php
functions not working


<?php

//upload.php

$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';

if(!empty($_FILES))
{

 $temp_file = $_FILES['file']['tmp_name'];
 $location = $folder_name . $_FILES['file']['name'];
 move_uploaded_file($temp_file, $location);
 $upload = $_FILES['file']['name'];
 $uploadStr = str_replace(" ", "\ ",$upload);
 $locationStr = str_replace(" ","\ ",$location);
 $cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
 echo shell_exec($cmd);
}


echo "The file " . $location . " has been uploaded";
// not working
echo "<br />";
echo "The file " . $upload . " has been uploaded";
// not working
echo "<br />";
echo "The file " . $uploadStr . " has been uploaded";
// not working
echo "<br />";
echo "The file " . $locationStr . " has been uploaded";
// not working

?>




this error :

About the developer solution Markus AO


I did the experiment and it is quite good, but dropzone is still missing, because I will upload a large video and the normal upload compresses the video before uploading, here is a picture from my mobile while uploading, but this does not happen with dropzone



I want to implement this in dropzone as well, because this library does not compress the video, but upload it in full size.


Thank you bro.

ffprobe does not show packet size of a mpeg transport stream as 188 bytes
16 octobre 2015, par CompNetI created a transport stream from a
H.264encoded file using the followingffmpegcommand :ffmpeg -i encoded.mp4 -c copy -map 0 -vbsf h264_mp4toannexb mpegts sample.tsNow I want to check the frames and packets within the transport stream. I used
ffprobe -show_frameswhich shows the frame details for audio and video frames. But I’m confused about the
pkt_sizefield. Is it the actual frame size of each elementary stream of audio and video (I/B/P frames) ?Also, when I run
ffprobe -show_packetsis it supposed to give each packet details in the transport stream ? Because the
sizefield of each packet is not 188 bytes, rather it is same as thepkt_sizeI got with-show_frames.Could someone please explain why the size in
-show_packetsof transport stream is not 188 bytes ? Did I do anything wrong while multiplexingmp4toTS?
