Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.
Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
All uploaded files are stored online in their original format, so you can (...)

os.system() returning False for some reason
22 février 2017, par Kendall WeiheI have a rather large program (memory-wise), it’s a neural network with Tensorflow. I’m working with volumetric data. My end goal is to use
ffmpegto create a video through the volume — where each frame is a z-slice. I’ve successfully done this before using theospython library. The code looks like this :videoFile = self.slicesPath + "/0.mp4"
sliceFiles = self.slicesPath + "/%04d.jpg"
os.system("ffmpeg -y -framerate 10 -start_number 0 -i " + sliceFiles + " -vcodec mpeg4 " + videoFile)When I step through this with
pdband I try to execute theos.system()command I get-1as if there were some error.(Pdb) os.system("ffmpeg -y -framerate 10 -start_number 0 -i " + sliceFiles + " -vcodec mpeg4 " + videoFile)
-1So then I printed the two variables...
(Pdb) sliceFiles
'/home/volcart/UnsupervisedResults/HercFragment/VAE/0/1/%04d.jpg'
(Pdb) videoFile
'/home/volcart/UnsupervisedResults/HercFragment/VAE/0/1/0.mp4'Opened up a python console in a new terminal tab, copy and pasted the exact same line of code (with the strings above instead of variable names), and BAM ! it magically works.
Why is this ? It works in a separate python console, it works in bash, but it doesn’t work inside my program (when it is the exact same thing). My only guess is something to do with memory, but I know for certain I am not out of memory... my machine has 64GB and python has no limits.
EDIT
I just tried a
subprocessinstead and got this :(Pdb) subprocess.call("ffmpeg -y -framerate 10 -start_number 0 -i " + sliceFiles + " -vcodec mpeg4 " + videoFile, shell=True)
*** OSError: [Errno 12] Cannot allocate memoryBut how is it unable to allocate memory ? Python doesn’t have memory bounds right ? I have 64GB of memory, and I can execute the
ffmpegcommand outside the program, so something is bounding my program. -
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);
}

 }
 }
}
$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";

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.
