文件目录结构如下:
——ffmpeg-3.3.8
——config.sh
——build_ffmpeg.sh
——build_ffmpeg_all.sh
编译指定架构的版本可以通过如下命令:
bash build_ffmpeg.sh armeabi-v7a
bash build_ffmpeg.sh x86_64
......
编译全平台支持的版本命令:
bash build_ffmpeg_all.sh
其中build_ffmpeg_all.sh
脚本内容如下:
for arch in armeabi armeabi-v7a arm64-v8a x86 x86_64
do
bash build_ffmpeg.sh $arch
done
输出结果:
开始编译x264库
先获取最新的x264库
git clone http://git.videolan.org/git/x264.git
脚本文件目录结构如下:
——x264
——build_x264.sh
——build_all_x264.sh
开始编译:
#编译指定平台
bash build_x264.sh armeabi-v7a
#编译全平台
bash build_all_x264.sh
稍等片刻即可生成相关的文件
image
开始编译fdk-aac库
先下载 fdk-aac-0.1.6版本
目录结构如下:
——fdk-aac-0.1.6
——build_fdkaac.sh
——build_all_fdkaac.sh
开始编译:
#编译指定平台
bash build_fdkaac.sh armeabi-v7a
#编译全平台
bash build_all_fdkaac.sh
输出如下:
ffmpeg混合编译x264和fdk-aar库
目录结构如下:
——fdk-aac-0.1.6
——x264
——ffmpeg-3.3.8
——libs
——build_ffmpeg_with_x264_fdkaac.sh
——build_ffmpeg_with_x264_fdkaac_all.sh
开始编译:
#编译指定平台
bash build_ffmpeg_with_x264_fdkaac.sh armeabi-v7a
#编译全平台
bash build_ffmpeg_with_x264_fdkaac_all.sh
混合输出结果:
