- libuavs3d
ffmpeg的官方源码中已经支持了libuavs3d解码器的接口(libavcodec/libuavs3d.c中定义),因此如果需要编译ffmpeg支持libuavs3d解码器,只需要安装libuavs3d.so以及开启ffmpeg的编译选项即可。
安装libuavs3d解码器
shell
#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 && make install
libuavs3d会安装的文件:
shell
/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libuavs3d.so,静态链接生成uavs3dec可执行文件,这样ffmpeg就不能使用libuavs3d库了。
- libuavs3e
ffmpeg官方源码中还未添加对libuavs3e库的支持,需要做一点修改。
安装libuavs3e编码器
shell
#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 && make install
uavs3e安装的文件比uavs3d的多一个
shell
/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
shell
#libavs3e.c开源代码仓库
git clone https://github.com/uavs3/uavs3e_ffmpeg_interface.git
ffmpeg中configure修改以及allcodecs.c修改:

编译时会报错,pkg-config找不到uavs3e,可以查看ffbuild/config.log中的具体错误,我这里是因为uavse.h头文件和uavs3e.pc中路径不匹配,直接把/usr/include/uavs3e/路径下的两个头文件拷贝到/usr/include/下面(和uavs3d.h路径一致了)

libuavs3e.c修改,为了适配较新的ffmpeg代码【编码还有问题】

ffmpeg的配置选项
./configure --enable-libuavs3d --enable-libuavs3e --enable-shared --disable-stripping --enable-ffplay --prefix=/usr
- 效果
- 解码播放avs3视频
- 编码yuv至avs3视频【编码出来的视频播放有问题,待调试解决】
