• Evolution #2965 : Abandonner le support ie8 et inférieur

  Peut être pas si loin que ça. Chez jQuery ils disaient « jQuery 2.0 (early 2013, not long after 1.9) ». On était à la béta 2 le 1er mars dernier. Donc, ça risque d’être dans la 3.1 à ce train là :) (j’avais loupé la bonne destination de ce message (...)

• FFMPEG : Invalid Pixel Format String -1 when converting MP3 to SWF

  22 janvier 2013, par James Riley

  I'm having an issue with FFMPEG - receiving an error when trying to convert an MP3 into an SWF. The full output contains :

  I'm aware the FFmpeg version here is old, but the issue is only occuring for one of the MP3s I am testing here. I have many others that are working just fine.

  What can be causing this issue and what steps can I take to resolve this ?

  From what I understand, the pixel format relates to the video output, yet in this case, the SWF is only to be used for audio. I've tested this on a newer version of FFmpeg and the issue isn't occuring - I certainly plan to upgrade FFmpeg on the test server I'm using, but would like to get to the bottom of why this is happening and try to get this particular MP3 converting, where its currently failing despite many others not having the same issue.

  Thanks for any help !

• Dissappearing characters in youtube-dl, ffmpeg, and windows

  4 juin 2014, par user3407161

  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.

  (Refer back to the error message, i’ll repost it below.)

  [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

  So as you can see, I think cmd passed on the symbol correctly to ffmpeg seeing from the adding metadata line, but when it actually does the operation ffmpeg loses

  ► and ◄

  Could this be a bug with ffmpeg ? MY workaround so far with incompatible symbols was to change the system locale, but I don’t think i can do that with these two symbols...

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