• MP3 file become silent when time changed in Firefox with audio API

  14 décembre 2022, par Simon Trichereau

  I have some problem but I need to give you some context :

  


  I have a production environment with large audio mp3 files. Everything is working perfectly but files are too heavy. I used ffmpeg to reduce their Bitrates from 320kbit/s to 190kbit/s to free space in my disk.

  


  My script worked well and I saved almost 50% of space, but before to put it in production I wanted to test it on pre-production and there is some problem with Firefox...

  


  When I play the audio everything is working good, if I listen to it normally everything is working BUT, when I click on the range to change the time and navigate into the audio, it becomes silent. Nothing happens, I can stop, start again, change the time, nothing works, but the audio is still playing...

  


  I don't have any errors in my console, nothing so the only solution is to reload the page and play again the audio without changing the time.

  


  I tried in chrome and it works like a charm, but in Firefox no. I also tried without any extensions and still the same...

  


  Do you have any idea what is happening ?

  


  Thanks a lot !

  


  --- EDIT 14/12/2022 ---

  


  Ok, I have tried a lot of different solutions and I finally found one, it seems firefox doesn't support VBR (variable bitrate) so I've compressed my file in CBR and it seems to finally work ...

  initially there was an error that ffmpeg was not found, I downloaded it separately, indicated the path to it and now it's coming out like this

  


• Why i get permission denied at docker ffmpeg execution

  24 octobre 2022, par Daniel Richter

  i want to make small gifs (miniclip) from a mp4 video using ffmpeg with php script in aws ecs.

  


  The whole configuration is working with the symfony built-in server. Now i put the controller into local docker and now i get the following permission denied error :

  What exactly tells me the error ? The folder /var/www/html/public/ exists but isnt writable ?

  


  The command from php i run the script is :

  


  $output = shell_exec('/usr/bin/ffmpeg -y -ss 255 -t 4 -i '.$url.' -vf "fps=10,scale=320:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 /var/www/html/public/'.$outputFile.' 2>&1');
echo $output;


  


  any idea is welcome.

  


  

  1. the user is wrong. shell_exec('whoami'); gives me www-data, but why ?? My dockerfile have the following in : RUN chown -R root:root /var/www/html/public
