一套rk3588 rtsp服务器推流的 github 方案及记录 -03(完结)
opencv 解码记录
解码库使用的时候发现瑞芯微以前做过解码库对ffmpeg和gstreamer的支持
然后最近实在不想再调试Rtsp浪费时间了，就从这中间找了一个比较快的方案
ffmpeg 带硬解码库编译
编译流程参考文献
https://blog.csdn.net/T__zxt/article/details/123424359
编译的ffmpeg是这个版本
https://github.com/jjm2473
安装了下面这些东西：
sudo apt-get -y install \
autoconf \
automake \
build-essential \
cmake \
git-core \
libass-dev \
libfreetype6-dev \
libsdl2-dev \
libtool \
libva-dev \
libvdpau-dev \
libvorbis-dev \
libxcb1-dev \
libxcb-shm0-dev \
libxcb-xfixes0-dev \
pkg-config \
texinfo \
wget \
zlib1g-dev
编译选项参考的是这哥们的语句：
https://www.reddit.com/r/OrangePI/comments/14f725v/comment/jpcezy2/?context=3
下面这句话，哪个不能用删哪个，一定要有的是 --enable-rkmpp
./configure --enable-nonfree --enable-gpl --enable-version3 --enable-libx264 --enable-libdrm --enable-rkmpp --enable-librtmp --enable-shared --enable-static --enable-librga --enable-libx265 --enable-libmp3lame --enable-libpulse --enable-openssl --enable-libopus --enable-libvorbis
# 我最后用的 应该是
sudo apt-get -y install autoconf automake build-essential cmake git-core libass-dev libfreetype6-dev libsdl2-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo wget zlib1g-dev
./configure --enable-nonfree --enable-gpl --enable-version3 --enable-libx264 --enable-libdrm --enable-rkmpp --enable-shared --enable-static --enable-librga --enable-libx265 --enable-libpulse --enable-openssl --enable-libvorbis
使用板上编译的时候记得多等一会，有点慢，不要急
编译出来的结果需要使用下面的语句去看ffmpeg是否正常
ffmpeg -decoders |grep h264
如果编译之后，ffmpeg不支持，
修改
sudo vim /etc/ld.so.conf
include /etc/ld.so.conf.d/*.conf
/usr/local/lib
打开之前ldd看一眼是不是所有的链接库都找到地方了

opencv编译带硬解码ffmpeg

opencv 4.5.5来讲，这个ffmpeg太新了，编译不过。只能以毒攻毒，去下了opencv4.8.0
回头把这个打包上传到csdn资源，防止它小更新不能用
4.8.0是编译通过的
一样也是板端编译，cmake-gui配置,然后去build文件夹下面 make make install

注意 ，如果使用qt，一定要把qt勾选，否则在qt里运行会报错
还有opencl他也不是自动勾选的
其他的应该随意
然后去创建工程使用、测试opencv是不是能正常用
