  lavf/url : fix relative url parsing when the query string or fragment has a colon
  This disallows the usage of ? and # in libavformat specific scheme options
  
  (e.g. subfile,,start,32815239,end,0,,:video.ts) but this change was considered
  
  acceptable.

• Subtract a specific string from a variable in a for loop

  14 octobre 2020, par Filip

  I am making a file converter with batch using FFMPEG.

  


  I have encountered a problem when trying to subtract the name of a file from the complete link to the file to get the directory of the folder it is in so after the file is converted it can be put into that directory.

  


  Can someone advise me on how I could subtract the string from the filename variable from the string in the directory

  


  My code :

  


  @echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set filetype=.flac
for /R %%a in ("*%filetype%*") do (
    set directory=%%a
    set filename=%%~na%filetype%
    set convdir=!directory:%filename%=!
    echo !convdir!
    pause
    ffmpeg -i "%%a" "convdir%%~na.wav"
    echo Converted %%a
)
echo Convertion Done!
pause


  


• PHP add whitespaces in string with an URL

  25 juin 2021, par Alberto Valerio

  Problem

  


  I have a temporary url to access an object from AWS-S3

  


  $source = "http://mybucket...";


  


  If I do a var_dump($source) it shows me the correct URL

  


  string(407) "https://mybucket.s3.amazonaws.com/storage/..."


  


  So I try to use this url in a ffmpeg command in this way (double quotes are required in ffmpeg)

  


  $cmd = 'ffmpeg -i "' . $source . '" ...
shell_exec($cmd);


  


  This do not work, and when I do a var_dump($cmd) the url shows like this (whitespace beetween https: and the // )

  


   "https: //mybucket.s3.amazonaws.com/storage/..."


  


  It works fine when I specify the url with the S3 protocol

  


  "s3://mybucket...."


  


  So maybe the problem is with the https protocol

  


  What I tried(It didn't work)

  


  

  • I tried $url = str_replace(' ', '', $source);

  


  • I tried $url = str_replace('%20', '', $source);

  


  • I tried $url = str_replace('https: //', 'https://', $source);

  


  • I tried $url = preg_replace("/\s+/", "", $source);

  


  • I tried addslashes($source) instead '"' . $source . '"'

  


  • I tried $url = escapeshellarg($source);

  


  


  What I'm using

  


  

  • Php 7

  


  • Laravel 4

  


  • AWS-S3
