mac ffmpeg环境搭建（流媒体开发学习4）

安装相关环境

硬件环境：

• nVidia 2060 2块

yum安装驱动

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm yum install yum-plugin-fastestmirror sudo vim /lib/modprobe.d/dist-blacklist.conf

dist-blacklist.conf

#blacklist nvidiafb blacklist nouveau options nouveau modeset=0

mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak dracut /boot/initramfs-$(uname -r).img $(uname -r) lspci | grep nouveau

没有输出，说明屏蔽默认带有的nouveau成功。

一些命令：

sudo yum install nvidia-detect nvidia显卡检测 nvidia-detect -v 检测结果 # yum -y install kmod-nvidia 安装显卡驱动 这一步应该不需要

run脚本安装

参考：https://github.com/keylase/nvidia-patch

cd /opt/nvidia wget https://international.download.nvidia.com/XFree86/Linux-x86_64/430.40/NVIDIA-Linux-x86_64-430.40.run chmod x NVIDIA-Linux-x86_64-430.40.run ./NVIDIA-Linux-x86_64-430.40.run --kernel-source-path=/usr/src/kernels/3.10.0-957.27.2.el7.x86_64 # 下面是移除NVENC同时运行最大数量的限制 restriction on maximum number of simultaneous NVENC git clone https://github.com/keylase/nvidia-patch cd nvidia-patch bash ./patch.sh

如果需要卸载，使用命令：

./NVIDIA-Linux-x86_64-430.40.run --uninstall

安装Cuda

sudo yum-config-manager --add-repo http://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-rhel7.repo sudo yum clean all sudo yum -y install nvidia-driver-latest-dkms cuda nvidia-smi

配置ffmpeg, 编译安装

下载

git clone https://git.ffmpeg.org/ffmpeg.git git clone https://github.com/libav/libav

配置

PKG_CONFIG_PATH="/usr/lib/pkgconfig" export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH cd ffmpeg ./configure --prefix="/usr" --pkg-config-flags="--static" --enable-gpl --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libxvid --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree --extra-cflags="-I/usr/local/cuda/include/" --extra-ldflags=-L/usr/local/cuda/lib64 --disable-shared --enable-nvenc --enable-cuda --enable-cuvid --enable-libnpp --enable-pthreads --enable-openssl

我实际编译去掉了–enable-libfdk-aac enable-libxvid

编译

make -j 10

安装

make install

使用 测试转码推流

ffmpeg -hwaccel cuvid -c:v h264_cuvid -i "rtsp://aaa:bbb@ip:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif" -c:v h264_nvenc -an -preset slow -tune film -f flv rtmp://rtmpip:port/live/v_test```
