  • How to Show result after uploaded file in PHP

    23 avril 2022, par i0x4r

    I 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

    &#xA;

    EDIT :&#xA;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.

    &#xA;

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

    &#xA;

    This is an example of that

    &#xA;

    &lt;?php&#xA;&#xA;//upload.php&#xA;&#xA;$folder_name = &#x27;upload/&#x27;;&#xA;$tumb_name = &#x27;thumb/&#x27;;&#xA;$imageext = &#x27;.png&#x27;;&#xA;&#xA;if(!empty($_FILES))&#xA;{&#xA;&#xA; $temp_file = $_FILES[&#x27;file&#x27;][&#x27;tmp_name&#x27;];&#xA; $location = $folder_name . $_FILES[&#x27;file&#x27;][&#x27;name&#x27;];&#xA; move_uploaded_file($temp_file, $location);&#xA; $upload = $_FILES[&#x27;file&#x27;][&#x27;name&#x27;];&#xA; $uploadStr = str_replace(" ", "\ ",$upload);&#xA; $locationStr = str_replace(" ","\ ",$location);&#xA; $cmd  = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&amp;1";&#xA; echo shell_exec($cmd);&#xA;}&#xA;&#xA;if(isset($_POST["name"]))&#xA;{&#xA; $filename = $folder_name.$_POST["name"];&#xA; $imagename = $thumb_name.$_POST["name"].$imageext;&#xA; unlink($filename);&#xA; unlink($imagename);&#xA;}&#xA;&#xA;&#xA;$output .= &#x27;Successfly file is "&#x27;.$location.&#x27;"&#x27;;&#xA;echo $output;&#xA;&#xA;?>&#xA;

    &#xA;

    Result : Successfly file is ""&#xA;no name file :(

    &#xA;

    EDIT 3 :

    &#xA;

    this code upload.php&#xA;functions not working

    &#xA;

    &lt;?php&#xA;&#xA;//upload.php&#xA;&#xA;$folder_name = &#x27;upload/&#x27;;&#xA;$tumb_name = &#x27;thumb/&#x27;;&#xA;$imageext = &#x27;.png&#x27;;&#xA;&#xA;if(!empty($_FILES))&#xA;{&#xA;&#xA; $temp_file = $_FILES[&#x27;file&#x27;][&#x27;tmp_name&#x27;];&#xA; $location = $folder_name . $_FILES[&#x27;file&#x27;][&#x27;name&#x27;];&#xA; move_uploaded_file($temp_file, $location);&#xA; $upload = $_FILES[&#x27;file&#x27;][&#x27;name&#x27;];&#xA; $uploadStr = str_replace(" ", "\ ",$upload);&#xA; $locationStr = str_replace(" ","\ ",$location);&#xA; $cmd  = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&amp;1";&#xA; echo shell_exec($cmd);&#xA;}&#xA;&#xA;&#xA;echo "The file " . $location .

    About the developer solution Markus AO

    &#xA;

    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&#xA;enter image description here

    &#xA;

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

    &#xA;

    Thank you bro.

  • Can't show image with opencv when importing av

    5 mars, par Flojomojo

    When importing the PyAv module, I am unable to show an image with opencv using imshow()

    &#xA;

    Code without the PyAv module (works as expected)

    &#xA;

    import cv2&#xA;&#xA;img = cv2.imread("test_image.jpeg")&#xA;cv2.imshow(&#x27;image&#x27;, img)&#xA;cv2.waitKey(0)&#xA;

    &#xA;

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

    &#xA;

    import cv2&#xA;import av&#xA;&#xA;img = cv2.imread("test_image.jpeg")&#xA;cv2.imshow(&#x27;image&#x27;, img)&#xA;cv2.waitKey(0)&#xA;

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