Can't show image with opencv when importing av
5 mars, par FlojomojoWhen importing the PyAv module, I am unable to show an image with opencv using imshow()


Code without the PyAv module (works as expected)


import cv2

img = cv2.imread("test_image.jpeg")
cv2.imshow('image', img)
cv2.waitKey(0)


Code with the import (doesn't work, just hangs)


import cv2
import av

img = cv2.imread("test_image.jpeg")
cv2.imshow('image', img)
cv2.waitKey(0)


OS : Linux arch 5.18.3-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 09 Jun 2022 16:14:10 +0000 x86_64 GNU/Linux


Am I doing something wrong or is this a (un-)known issue ?

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

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

?>

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.
