ffmpeg编译支持AVS3编解码_代码007(未授权)

本文介绍: linux 平台下编译 ffmpeg 支持AVS3编解码

#代码仓库
git clone https://github.com/uavs3/uavs3d.git
#可以参考其仓库说明安装，这里使用linux平台
apt install gawk cmake #安装依赖
cd uavs3d
mkdir build/linux
cd build/linux
cmake -DCOMPILE_10BIT=1 -DBUILD_SHARED_LIBS=1 --install-prefix=/usr ../..
make &amp;&amp; make install

libuavs3d会安装的文件：

/usr/lib/libuavs3d.so
/usr/include/uavs3d.h
/usr/lib/pkgconfig/uavs3d.pc

如果编译得时候没有-DBUILD_SHARED_LIBS，则uavs3d不会生成 li bu a vs3d.so，静态链接生成ua vs3dec可执行文件，这样ffmpeg就不能使用 li bu a vs3d库了。

#代码仓库
git clone https://github.com/uavs3/uavs3d.git
apt install gawk cmake #安装依赖
cd uavs3e
mkdir build/linux
cd build/linux
cmake -DCOMPILE_10BIT=1 -DBUILD_SHARED_LIBS=1 --install-prefix=/usr ../..
make &amp;&amp; make install

uavs3e安装的文件比uavs3d的多一个

/usr/lib/libuavs3e.so
/usr/include/uavs3e/uavs3e.h
/usr/include/uavs3e/com_api.h
/usr/lib/pkgconfig/uavs3e.pc

ffmpeg添加libuavs3e.c及接口支持

#libavs3e.c开源代码仓库
git clone https://github.com/uavs3/uavs3e_ffmpeg_interface.git

ff mpeg中configure 修改以及all code cs.c修改：
