• Dissappearing unicode characters in Windows

  3 juin 2014, par user3698015

  so what happens is that if the video title has a symbol that isn’t supported by your current locale then ffmpeg won’t be able to get to that file properly.

  Here’s one example

  ►2 HOURS BEST MELODIC DUBSTEP MIX APRIL 2013◄ ヽ( ≧ω≦)ﾉ

  as you may or may not be able to see, lots of symbols from unicode.

  The problem is that in cmd and ffmpeg, though cmd can see

  ►2 HOURS BEST MELODIC DUBSTEP MIX APRIL 2013◄ ヽ( ≧ω≦)ﾉ

  ffmpeg only sees

  2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013 ヽ(≧ω≦)ﾉ

  This is the exact error message (i’m using youtube-dl)

   [ffmpeg] Adding metadata to 'C:\Music\ToBeDone\2014-06-01\►2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013◄ ヽ( ≧ω≦)ﾉ.mp4'
  
      ERROR: C:\Music\ToBeDone\2014-06-01\2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013 ヽ(≧ω≦)ﾉ.mp4: No such file or directory
  
      ERROR: WARNING: unable to obtain file audio codec with ffprobe

  After some research i’ve determined that by changing the system locale you can change which symbols cmd can support.

  However

  ヽ

  Used to appear as a box in a question mark in United states locale. In japanese locale it appears as it does on your screen right now.

  the problem with

  ◄

  is that even though it’s not appearing as a question mark in a box (it’s appearing as how it should be), ffmpeg (or cmd) can’t detect it properly.

  These are the unique characters that i need to have a locale that supports

  and this is what's going on (Batch Script)
  
  
  
  @echo off
  
  setlocal
  
  cd C:\youtube-dl
  
  
  
  set /p "var1=Enter URL: " %=% pause
  
  if defined var1 set "var1=%var1:"=%"
  
  set "var2=%date:/=-%" 
  
  set "var3=%%(title)s.%%(ext)s"
  
  youtube-dl "%var1%" -ci -o "C:\Music\ToBeDone\%var2%\%var3%" -f best -x --no-mtime --add-metadata 
  
  youtube-dl "%var1%" --skip-download -ci -o "C:\Music\ToBeDone\%var2%\Thumbnail\%var3%" --write-thumbnail
  
  youtube-dl "%var1%" --skip-download -ci -o "C:\Music\ToBeDone\%var2%\Description\%var3%" --write-description

  so i found the symbol but i’m having trouble in finding out how each locale relates to the symbol...

  Like what about each locale makes the symbol usable to cmd ?

• How do I compile a 64-bit version of ffmpeg on Windows ?

  30 septembre 2016, par lyxera

  i need to compile ffmpeg (64 bit shared dll) for windows.
  however I configure in mingw, it always produces 32 bit binary for me.

  tried this already

  ./configure --enable-shared --disable-static --enable-memalign-hack --arch=amd64
  
  ./configure --enable-shared --disable-static --enable-memalign-hack --arch=x86_64

  my guess is that a x86 to x86_64 cross compiler is missing.

  but just can find a way to make those 64bit dlls.
