libfdk-aac for Windows binary builder

libfdk-aac (0.1.6 and 2.0.2) and fdkaac tool (1.0.3) for Windows auto binary builder scripts.

CI build (master)

fdk-aac is "A standalone library of the Fraunhofer FDK AAC code from Android." A mirror of released source code, see official opencore-amr project.

fdkaac is "command line encoder frontend for libfdk-aac".

It'll build both:

  • libfdk-aac-1.dll
  • libfdk-acc-2.dll
  • fdkaac.exe (Linked libfdk-aac-2.dll)

How to use

  1. Install MSYS2
  2. Open MSYS2 shell terminal.
  • Choose MSYS2 MinGW-32bit terminal if you wanna 32bit (i686) binary.
  • Choose MSYS2 MinGW-64bit terminal if you wanna 64bit (x86_64) binary.
  • DON'T USE MSYS2 (unannoteted) terminal.

Terminals

  1. Update components by pacman. (See MSYS2 top page.)
  2. Install development tools.
  • Execute pacman -S mingw-w64-i686-gcc autoconf automake-wrapper make libtool if you wanna 32bit binary.
  • Execute pacman -S mingw-w64-x86_64-gcc autoconf automake-wrapper make libtool if you wanna 64bit binary.
  1. Execute ./setup.sh, it'll download source code archive and extract reference files for testing purpose.
  2. You can choose GCC's optimization option by editing build.sh. See CFLAGS symbols in the head of this file.
  3. Execute ./build.sh.

Finally, stored binaries into artifacts directory.

  • artifacts/i686-w64-mingw32/ (32bit)
  • artifacts/x86_64-w64-mingw32/ (64bit)

If you have to get results for PCM bits equality, you can execute ./test.sh after building was successful. The test materials are generated by a specific version of the encoder, so they can only be used for verifying specific version of fdk-aac, (see here for detailed information). It'll use cmp command, so will show nothing output if these PCM files are verified. For example:

$ ./test.sh
Step 1. Generating reference PCM files
Step 2. Generating test AAC files using fdkaac.exe with libfdk-aac-2.dll
Step 3. Generating test PCM files
Step 4. Comparing PCM files
