• Usage of libx264.dll in C++ under windows

  19 janvier 2012, par Anuj

  I have been able to build the libx264 dll from source using hints from here.
  I am successfully able to load the Dll via my application using the LoadLibrary method.
  But when i try to get the address of the methods available via the x264.h header using GetProcAddress(), i always get back NULL.

  Has anyone worked with libx264.dll before in VS or are there any references to some sample code for the same.

• FFmpeg Windows directshow filter

  24 mai 2016, par kiwijus

  I’m trying to open a directshow video source (webcam/push source) using the ffmpeg api however I’m not having any luck.
  I’ve tried using

  av_open_input_file()

  however I don’t think this is the right way... Does anyone have any pointers ?

  I’m using visual studio and c++ on a windows system

• 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
