`ffmpeg`: Fails to build while applying patch `020-ffmpeg-fix-build-with-fdk-aac-2.0.patch` and other fdkaac patches.

[dreirund]

Ahoj,

when I try to build libffmpeg-audio-dec from the HandsomeMod/packages feed, it fails while applying the patch 020-ffmpeg-fix-build-with-fdk-aac-2.0.patch:

[...]
Applying ./patches/020-ffmpeg-fix-build-with-fdk-aac-2.0.patch using plaintext: 
patching file libavcodec/libfdk-aacenc.c
Hunk #1 succeeded at 35 with fuzz 2 (offset 9 lines).
Hunk #2 FAILED at 291.
Hunk #3 FAILED at 324.
2 out of 3 hunks FAILED -- saving rejects to file libavcodec/libfdk-aacenc.c.rej
[...]

→ Here is the libavcodec/libfdk-aacenc.c.rej.

After a failing make -j6, → here is the terminal output of make -j1 V=sc package/feeds/packages/ffmpeg/compile.

Configuration:

• grep -i ffmpeg .config:

  CONFIG_PACKAGE_libffmpeg-audio-dec=m
  # CONFIG_PACKAGE_libffmpeg-custom is not set
  # CONFIG_PACKAGE_libffmpeg-full is not set
  # CONFIG_PACKAGE_libffmpeg-mini is not set
  # CONFIG_PACKAGE_ffmpeg is not set
  

• → Full .config.
