android下打算使用ffmpeg的 drawtext ，不过需要 --enable-libfreetype  但是freetype是个第三方库，所以需要先编译freetype，然后再编译ffmpeg

在网上找了个好的教程：

编译流程：

Instructions

• Set environment variable
  1. export ANDROID_NDK={Android NDK Base Path}
• Run following commands to compile ffmpeg
  1. sudo apt-get --quiet --yes install build-essential git autoconf libtool pkg-config gperf gettext yasm
  2. ./init_update_libs.sh
  3. ./android_build.sh
• To update submodules and libraries you can use ./init_update_libs.sh command
• Find the executable binary in build directory.
• If you want to use FONTCONFIG then you need to specify your custom fontconfig config file (e.g - "FONTCONFIG_FILE=/sdcard/fonts.conf ./ffmpeg --version", where /sdcard/fonts.conf is location of your FONTCONFIG configuration file).
• You can also download prebuilt-binaries.zip prebuilt-binaries.tar.gz here.
