Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.
Version mono serveur

NVIDIA Version Outdated Error when mine is updated
21 février 2021, par Agent MerlotI'm trying to encode stuff with my NVIDIA GeForce MX150 (Driver Version : 461.09).


import os
os.system(f'ffmpeg -i "Cells at Work Season 2 - Episode 07 - English Subbed.mp4" -c:a copy -c:v hevc_nvenc "07.mp4"')

Whenever I'm trying to run it, I'm getting this error.


[hevc_nvenc @ 0000017a8bdf7e40] Cannot load nvEncodeAPI64.dll
[hevc_nvenc @ 0000017a8bdf7e40] The minimum required Nvidia driver for nvenc is 436.15 or newer
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!

What bugs me is that it says that I need 436.15 or newer, and mine is 461.09. That means it should work, right ? Can anyone help ?

FFmpeg Throwing Up Error After Concat Attempt [closed]
8 mai 2021, par OrdinaryCarrot16I am trying to convert my DVDs using FFmpeg, while doing additional filtering and concatenation. The script I am making is very WIP, but it isn't working at the moment. It throws up the error : "No such filter : ''
Error initializing complex filters.
Invalid argument"


Am I using the correct syntax ?

Why does File upload for moving image and Audio to tmp PHP folder work on Windows but only image upload portion works on Mac using MAMP ?
31 mai 2021, par YazdanSo according to my colleague who tested this on Windows says it works perfectly fine , but in my case when I use it on a Mac with MAMP for Moodle , the image files get uploaded to the correct destination folder without an issue whereas the audio files don't move from the tmp folder to the actual destination folder and to check if this was the case ... I just changed and gave a fixed path instead of
$fileTmpLocand the file made it to the correct destination. Sorry I know the first half of the code isn't the main issue but I still wanted to post the whole code so one could understand it easily, moreover I am just beginning to code so please "have a bit of patience with me" . Thanks in advance

I am a student learning frontend but a project of mine requires a fair bit of backend. So forgive me if my question sounds silly.


What I meant by manually overriding it was creating another folder and a index.php file with
echo "hello"; $output = shell_exec("ffmpeg -i Elephant.mp3 -ab 160k -ac 2 -ar 44100 -vn bub.mp3"); echo $output;so only yes in this caseElephant.mp3was changed as the initial tmp path so in this case as suggested by Mr.CBroe the permissons shouldn't be an issue.

Okay I checked my
Apache_error.logonly to find out ffmpeg is indeed the culprit ... I had installedffmpegglobally so I am not sure if it is an access problem but here is a snippet of the log

I checked my php logs and found out that
FFmpegis the culprit.
Attached is a short log file
