Running ffmpeg on cmd works, but integrating it with PHP gives out an error
11 juin 2022, par digiboyRunning ffmpeg to covert files to mp4 works normally when ran from a command line prompt, but
upon trying to integrate it into a php code I keep getting errors and I am not sure why that is. The error says :


'-i' is not recognized as an internal or external command,
operable program or batch file.
Upload failed 


This is the function that is responsible for running ffmpeg code that converts the file :


public function convertVideoToMp4($tempFilePath, $finalFilePath) {
 $cmd = "$this->ffmpegPath -i $tempFilePath $finalFilePath 2>&1";

 $outputLog = array();
 exec($cmd, $outputLog, $returnCode);

 if($returnCode != 0) {
 //Command failed
 foreach($outputLog as $line) {
 echo $line . "<br />";
 }
 return false;
 }

 return true;
}


and since my code is returning an error pointing to a command line command being faulty, I am guessing it is triggering the
echo $line . "<br />";from the function above.
However, right under this error output, I have an errorUpload failed
which points to a different function in the program, mainly the one responsible for the upload of the file itself :

if(move_uploaded_file($videoData["tmp_name"], $tempFilePath)) {
 $finalFilePath = $targetDir . uniqid() . ".mp4";

 if(!$this->insertVideoData($videoUploadData, $finalFilePath)) {
 echo "Insert query failed\n";
 return false;
 }

 if(!$this->convertVideoToMp4($tempFilePath, $finalFilePath)) {
 echo "Upload failed\n";
 return false;
 }

 if(!$this->deleteFile($tempFilePath)) {
 echo "Upload failed\n";
 return false;
 }

 if(!$this->generateThumbnails($finalFilePath)) {
 echo "Upload failed - could not generate thumbnails\n";
 return false;
 }

 }


But even though I get the output saying Upload failed, my file DOES get transfered into the folder that is dedicated as the "Upload folder" but the file is NOT converted from flv to mp4 before being uploaded, so I am left very confused.


For those who are wondering what the whole code looks like, this is VideoProcessor.php :


<?php
class VideoProcessor {

 private $con;

Pycord Music Bot : AttributeError : 'FFmpegAudio' object has no attribute '_process'
5 juin 2022, par Steven MaoI've made a discord Cog that should be able to queue up and play music, but I'm getting an error from FFmpeg when I actually try to play the URL. I have found an identical question on StackOverflow, but this user's problem was a random typo. The inputs should all be correct, so I am not sure if the problem is my code or my package.


What have I done wrong ?
