• Ffmpeg Symfony5 PHP8 [duplicate]

  11 septembre 2021, par Kévin Ducrocq

  I'm a french student learning web development, and how to create websites on Symfony 5.

  


  I've got this project to create a kind of Youtube website using Ffmpeg to convert and treat videos.

  


  However, when I try to use the "composer require php-ffmpeg/php-ffmpeg" command, it doesn't work and I really don't know what to do.

  


  here's the error I've got :

  


  PS C :\Users\Dev\Documents\Dev\Symfony\Youride> composer require php-ffmpeg/php-ffmpeg
Using version ^0.18.0 for php-ffmpeg/php-ffmpeg
./composer.json has been updated
Running composer update php-ffmpeg/php-ffmpeg
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  


  Problem 1
- Root composer.json requires php-ffmpeg/php-ffmpeg ^0.18.0 -> satisfiable by php-ffmpeg/php-ffmpeg[v0.18.0].
- php-ffmpeg/php-ffmpeg v0.18.0 requires doctrine/cache ^1.0 -> found doctrine/cache[v1.0, ..., 1.12.1] but it conflicts with your root composer.json require (^2.1).

  


  Use the option —with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

  


  Installation failed, reverting ./composer.json and ./composer.lock to their original content.
PS C :\Users\Dev\Documents\Dev\Symfony\Youride>

  


  thank you for your help, I'm a beginner... :)

  


• When merging video and audio, converting audio to AAC, sound is missed at the end 3 seconds

  10 octobre 2013, par profuel

  I have to build video from images and some audio clip.
  Audio is much longer, so I have to mute last 5 seconds of audio track, cutting to video length.
  My issue is that adding AAC encoding to audio removes last 2-5 seconds of audio in resulted video.
  
  Here are my command lines :

  ffmpeg -i sound.mp3 -i video.mp4 -shortest out.mp4 -> results in correct audio in result video with played audio over 100% of movie

  ffmpeg -i sound.mp3 -i video.mp4 -acodec aac -ab 160000 -strict experimental -shortest out.mp4 -> not correct audio, gets crop at end of video for 2-5 seconds
  
  
  The problem appears for me both on Windows and on CentOS 6.4, no matter which version of ffmpeg is used.

• Capture xvfb stream from docker container using webRTC [closed]

  I have a windows game .exe file and running the game inside a docker container (In EC2 linux VM) using xvfb version of X server. Now I want to Capture X server stream from docker container to my local system using webRTC. What should I do for the same ?

  


  Here's my Dockerfile :

  As of now I'm capturing the xserver stream using ffmpeg and storing the same in .mp4 file. Now I want to play the game on my local machine by using webRTC for connection and streaming.

  


  I have run the .exe in linux using wine and xvfb server and captured the stream using ffmpeg and stored in a .mp4 file.
