ubuntu下编译ffmpeg
Ubuntu下编译ffmpeg
官网指导：https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
下载源代码
git clone https://git.ffmpeg.org/gitweb/ffmpeg.git
切换分支
查看远程分支，切换release版本最新的分支到本地，为了稳定，编译少bug，选择release版本的
git branch -a
git checkout -b remotes/origin/release/4.1
在当前目录创建个bin文件夹，最为编译安装文件夹
mkdir bin

安装libvpx
VP8/VP9 video encoder/decoder
启用需要 configured 配置 --enable-libvpx
sudo apt-get install libvpx-dev -y
libfdk-aac
AAC audio encoder.
Requires ffmpeg to be configured with --enable-libfdk-aac (and --enable-nonfree if you also included --enable-gpl)
sudo apt-get install libfdk-aac-dev -y
libmp3lame
MP3 audio encoder.
Requires ffmpeg to be configured with --enable-libmp3lame.
sudo apt-get install libmp3lame-dev -y
libopus
Opus audio decoder and encoder.
Requires ffmpeg to be configured with --enable-libopus.
sudo apt-get install libopus-dev -y
libaom
AV1 video encoder/decoder:
手动安装在ffmpeg_build文件夹下，也可以收到下载release版本编译安装
git -C aom pull 2> /dev/null || git clone --depth 1 https://aomedia.googlesource.com/aom && \
mkdir aom_build && \
cd aom_build && \

make install
配置configure
生成静态库，动态库, 安装到相对目录./bin文件下
./configure --prefix=./bin--enable-static --enable-shared
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
--prefix="$HOME/ffmpeg_build" \
--pkg-config-flags="--static" \
--extra-cflags="-I$HOME/ffmpeg_build/include" \
--extra-ldflags="-L$HOME/ffmpeg_build/lib" \
--extra-libs="-lpthread -lm" \
--bindir="$HOME/bin" \
--enable-gpl \
--disable-libaom \
--enable-libass \
--enable-libfdk-aac \
--enable-libfreetype \
--enable-libmp3lame \
--enable-libopus \
--enable-libvorbis \
--enable-libvpx \
--enable-libx264 \
--enable-libx265 \
--enable-shared \
--enable-nonfree && \
PATH="$HOME/bin:$PATH" make -j 8 && \
make install && \
hash -r
编译并安装
#-j 8 多个编译一起执行，加快变异速度。多线程？多核处理？
make -j 8
#安装
make install
在bin文件夹中lib有生成的静态库和动态库
