• How to build FFmpeg with Apple Symbols ?

  22 septembre 2021, par Meh.

  MOVED FROM : https://superuser.com/questions/1676856/how-to-build-ffmpeg-with-apple-symbols?noredirect=1#comment2572799_1676856

  


  I'm trying to build FFmpeg 3.2.4 with OpenSSL >= 2.0.7 (3.0.0) from source so I can use it's binaries to build Dolphin-Emu.

  


  I just do this : ./configure --enable-gnutls and when I build with make -j5 (-j5 speeds up the process) then make install. When I use it in compiling Dolphin , I get an error somewhat like this :

  


  Undefined symbols for architecture x86_64:
  "_kCVImageBufferColorPrimaries_ITU_R_709_2", referenced from:
      _vtenc_init in libavcodec.a(videotoolboxenc.o)

(example)


  


  These _kV(blahblahblah) symbols are provided by Apple... under <coremedia></coremedia>CoreMedia.h> so my mac should DEFINITELY have this. OpenSSL version is 3.0.0 as there's an error about _SSLSetCertificate not existing.

  


  Does anyone have any ideas why this is throwing undefined symbols for existing symbols ? (My FFmpeg is compiled by clang whenever I use make, and I use gnutls(installed by brew) which should rely on openssl3.0)

  


  Xcode version : 11.3.1 (Only has macos 10.15 SDK)

• Does FFMPEG support AES128 Sample encryption required for Apple Fairplay DRM ?

  29 avril 2019, par Sathish Rao

  I need to encrypt an MPEG2 Transport stream with Sample AES encryption compatible with Fairplay DRM. Does FFMPEG support Sample AES encryption (just like how it supports Common Encryption for Widevine and Playready DRMs) ?
